Description

The present invention relates to a cooling sensation mat containing a phase change material (phase change constant temperature material) as an intermediate material, and particularly to a curing prevention cooling sensation mat for preventing the occurrence of curing of the intermediate material. Here, the phase change constant temperature material is as described below.

The so-called cooling sensation mat contains an anhydrous phase change material (phase change constant temperature material) as a main material. Therefore, when the external temperature (that is, the environment temperature in which the cooling mat is used) rises, the phase change material absorbs heat and changes from solid (gel/gel) to liquid, and the external temperature changes. When descending, the phase change material dissipates the absorbed heat and changes from liquid to solid. The “curing prevention cooling sensation mat” of the present invention utilizes the process of absorbing the heat quantity of the outside, especially the process of absorbing the heat of the outside during the temperature change of the external environment as described above. The surface temperature is lowered, and as a result, a cooling effect is given to the human body.

Cooling mats that are commonly used in the market today are included in the filling material filled in the mat during the use process (that is, during the solid-to-liquid, liquid-to-solid circulation process described above). In many cases, the crystals of the constituents become non-uniform, and as a result, large lumps (crystal lumps) are generated in the middle material, and they harden. As a result, there is a problem in that the body part of the person who uses the cooling sensation mat touches such a lump, and the sensation becomes unpleasant and the satisfaction of the user decreases. Further, since the shape of the large crystal mass as described above is irregular and some of them are sharp, during use, such a crystal mass breaks through the material (sheet etc.) wrapping the middle material, There is also a problem that the middle material may leak.

(Meth)acrylic monomer, (meth)acrylic polymer having a specific weight average molecular weight, and oil-soluble polymerization, as a heat storage material composition having excellent heat storage properties and excellent workability and workability without leakage of the heat storage material. A heat storage material composition containing an initiator and an organic latent heat storage material is known (see, for example, Patent Document 1). However, this heat storage material composition has an excellent latent heat effect, is soft to the human body as in the present invention, and makes the crystal size of the composition small and uniform to prevent the generation of large lumps. I have no doubt.

Also, in order to provide accurate phase change and stable functionalized material in a specific temperature range where the latent heat loss of the latent heat storage material composition is reduced, sodium sulfate hydrate (Glauber's salt) mainly composed of electrolyte hydrate And a normal temperature heat storage material, and a surfactant such as tetrasodium pyrophosphate hydrate useful for the ion exchange ability of cations and anions for suppressing the crystal habit of Glauber's salt associated with the phase change, and ammonia salts for setting the melting point freezing point, It contains ethylenediamine, sodium tetraborate as a supercooling prevention catalyst, a zeolite composite in a phase separation prevention suspension, and nanocarbon as a heat transfer promoter, and is solid-liquid reversible in a low temperature range, and has a transition point from 8°C to 12°C. There is known a latent heat storage material that requires (for example, refer to Patent Document 2). However, there is a possibility that a large lump (crystal lump) is generated in such a latent heat storage material and that it hardens, the latent heat effect is excellent, and it is soft to the human body like the present invention. It is unclear whether or not the size of the crystal of the composition is made small and uniform to prevent the generation of large lumps.

Further, a cold storage material capable of maintaining a melting temperature in a low temperature range of -13°C or higher and -2°C or lower, developing a stable temperature holding time in the temperature range, and preventing contamination of the cold storage material composition due to container damage as much as possible. To provide a composition, a gel-like aqueous solution comprising a melting temperature adjusting agent, a gelling agent, and water, containing urea as a melting temperature adjusting agent in an amount of 2.0% by weight or more and 20% by weight or less, and -13°C. A cold storage composition having a melting temperature in the range of not less than −2° C. is known (for example, see Patent Document 3). However, there is a possibility that a large lump (crystal lump) is generated in such a regenerator composition and that it hardens, and it is soft to the human body as in the present invention, and the crystal of the composition is It is unclear whether the size is made small and uniform to prevent the formation of large lumps.

Thus, in order to satisfy the person using the cooling mat, the feeling of the mat itself is soft to the human body, and the part of the body touching the mat is sufficiently cooled to obtain a satisfactory cooling effect. Currently, development is required.

An object of the present invention is to solve the above-mentioned problems of the prior art. The feeling of the cooling mat itself is soft to the human body lying on the mat, and the part of the body touching the mat is sufficiently cooled. An object of the present invention is to provide an anti-curing cooling sensation mat that can achieve a satisfactory cooling effect. According to the present invention, in order to prevent the occurrence of the hardening phenomenon of the cooling sensation mat, the size of the crystal of the middle material can be reduced by adding an auxiliary agent such as a hardening preventive agent, an anti-settling agent or a dispersant to the middle material. In addition, it becomes possible to prevent the formation of large lumps and improve the comfort of the user.

In the curing prevention cooling sensation mat of the present invention, two sheets having the same polygonal shape are overlapped with each other, the outer peripheral edge portion of the polygonal shape is fixed, and a space is formed inside, A plurality of chambers are defined between the upper and lower sheets, and each of these chambers contains a simple substance, a thickener, a hardening agent, a cross-linking agent, a suspending agent, a dispersant, and an antifungal agent. , And a gel composition composed of water as a middle material, wherein the simple substance is a mixture of sodium sulfate decahydrate, polyethylene glycol, sodium chloride, and paraffin wax, and the thickener is poly It is composed of one selected from sodium acrylate, methyl pralidoxime iodide, carboxymethyl cellulose, and carbomer, and the crosslinking agent is borax, N,N′-methylenebisacrylamide, or a silane coupling agent. That the anti-hardening agent is sodium aluminosilicate, the precipitation inhibitor is made of fumed silica, the dispersant is sodium polymetaphosphate, the antifungal antibacterial agent, from zinc oxide And the middle material is 70.0 to 80.0% by weight of the above-mentioned simple substance, 0.1 to 0.5% by weight of thickening agent, 1.0 to 5.0% by weight of curing agent, and cross-linking. Agent 1.0 to 10.0% by weight, suspending agent 1.0 to 5.0% by weight, dispersant 1.0 to 5.0% by weight, antifungal antibacterial agent 1.0 to 5.0% by weight, And 1.0 to 5.0% by weight of water.

According to the anti-hardening cooling sensation mat of the present invention, compared to the conventional technique, the lump of the components filled in the cooling sensation mat is crystallized from the liquid without the formation of crystal lumps of the components in the intermediate sensation. The problem of easy hardening during the circulation process is solved.

In the above-mentioned middle material components, a simple substance is 70.0 to 80.0% by weight, a thickener is 0.1 to 0.5% by weight, a hardening agent is 1.0 to 5.0% by weight, and a crosslinking agent is 1%. 0.0 to 10.0% by weight, precipitation inhibitor 1.0 to 5.0% by weight, dispersant 1.0 to 5.0% by weight, antifungal antibacterial agent 1.0 to 5.0% by weight , And water is 1.0 to 5.0% by weight, the anti-curing cooling mat of the present invention can achieve the intended purpose. That is, the feeling of the cooling mat itself is soft to the human body lying on the mat, and the part of the body touching the mat is sufficiently cooled to obtain a satisfactory cooling effect, and the cooling mat is filled in the mat. It is possible to prevent the hardening phenomenon of the middle material. By adding auxiliary agents such as hardening agents, suspending agents, and dispersants to the middle material, the size of the crystals of the middle material can be made small and uniform, preventing the formation of large lumps and making the user feel comfortable. It is possible to improve.

However, if the content of the simple substance is less than 70.0% by weight, it tends to remain in a liquid state even in a low temperature environment and to cause little crystallization, which makes it difficult to obtain a heat absorption effect. If it exceeds 0.0% by weight, the middle material remains solid even when it is in a low temperature state, and it is too hard to be in a crystalline state and becomes sandy, which makes it uncomfortable to sleep and further increases the cost. If the thickening agent is less than 0.1% by weight, the preferable anti-curing cooling mat of the present invention cannot be obtained, and if it exceeds 0.5% by weight, the present invention is unfavorable. It is useless because it is not possible to obtain the preferable anti-cooling mat of the present invention, and it tends to be too costly, and when the anti-hardening agent is less than 1.0% by weight, the preferable anti-cooling mat of the present invention is obtained. If the mat cannot be obtained and the amount exceeds 5.0% by weight, the cost tends to be too high, which is wasteful, and if the amount of the cross-linking agent is less than 1.0% by weight, preferable curing prevention of the present invention is prevented. If the cooling mat cannot be obtained and the content exceeds 10.0% by weight, the preferred curing-preventing cooling mat of the present invention cannot be obtained, and the cost tends to be too high. When the content of the inhibitor is less than 1.0% by weight, the preferable anti-curing cooling mat of the present invention cannot be obtained, and when it exceeds 5.0% by weight, the preferable anti-curing cooling mat of the present invention is obtained. However, if the dispersant is less than 1.0% by weight, the dispersion of each component tends to be insufficient from the stage of manufacturing the intermediate material. Even if mixed, the fusion effect between the components is low, and after the final product, there is a tendency that the phenomenon of partial melting is rapid and insufficient crystallization tends to occur, and it exceeds 5.0% by weight. When it is not possible to obtain the preferable hardening sensation cooling sensation mat of the present invention and it tends to be too costly, it is wasteful, and when the antifungal antibacterial agent is less than 1.0% by weight, mold and bacteria are present. Tend to breed, and if it exceeds 5.0% by weight, it tends to be too costly and wasteful, and if the amount of water is less than 1.0% by weight, the viscosity of the intermediate material increases, It is not preferable as a product, and if it exceeds 5.0% by weight, the viscosity becomes low, it is not preferable as a product, it remains in a liquid state even in a low temperature environment, and there is a problem that it hardly crystallizes. It tends to be difficult to obtain effects.

As described above, according to the intermediate material filled in the anti-curing cooling mat of the present invention, the synergistic action of the anti-hardening agent, the suspending agent, and the dispersant is utilized, so that the particles of each component are The adhesive force can be improved and the hardening phenomenon of the cooling matte middle material can be prevented.

According to the curing prevention cooling sensation mat of the present invention, in addition to a single component (main component material), a thickener, a curing inhibitor, a suspending agent, and a dispersant are added to prevent the curing phenomenon during the circulation process and prevent product damage. It also has the effect of lowering risk.

According to the curing prevention cooling sensation mat of the present invention, the feeling of the cooling sensation mat itself is soft to the human body lying on the mat, and the part of the body touching the mat is sufficiently cooled, and a satisfactory cooling effect is obtained. There is an effect that it is possible to provide a curing prevention cooling sensation mat.

According to the curing prevention cooling sensation mat of the present invention, the curing phenomenon of the cooling sensation mat is prevented from occurring, and the size of the crystals of the intermediate material filled in the mat is made small and uniform to prevent the generation of large lumps. Therefore, there is an effect that the sleeping comfort of the user can be improved.

According to the anti-curing cooling sensation mat of the present invention, a cool sensation is maintained, so that it does not become slimy even when used for a long time. Also, since it crystallizes by cooling at 30° C. or lower and absorbs heat at 30° C. or higher to liquefy, it can be kept cold at any time if it is laid in a room at ordinary temperature. If you sweat, wipe the surface of the mat with a towel etc. to keep it clean and easy to maintain.

Hereinafter, embodiments according to the present invention will be described. First, an outline of the embodiment will be described, and then individual components will be described.

According to the embodiment of the anti-cooling cooling mat according to the present invention, the anti-cooling cooling mat has the same size of various shapes such as a polygonal shape (eg, rectangle, square, etc.), a circle, an ellipse, and the like. The two sheets are overlapped, all the edge portions of the outer periphery of the polygonal shape are fixed to form a space inside, and various sheets are divided between the upper sheet and the lower sheet. A plurality of chambers in the shape of is formed, and in each of these chambers, a gel composition consisting of a simple substance, a thickener, a curing agent, a cross-linking agent, a suspending agent, a dispersant, an antifungal agent, and water is contained. It is filled as a material, and this middle material is 70.0-80.0% by weight, thickener 0.1-0.5% by weight, hardening agent 1.0-5.0% by weight, cross-linking Agent 1.0 to 10.0% by weight, suspending agent 1.0 to 5.0% by weight, dispersant 1.0 to 5.0% by weight, antifungal antibacterial agent 1.0 to 5.0% by weight, And 1.0 to 5.0% by weight of water.

The following is an example of the above components. The simple substance is, for example, preferably an inorganic phase transfer agent composed of at least one selected from sodium sulfate decahydrate (Glauber's salt), sodium sulfate, anhydrous sodium sulfate, polyethylene glycol, paraffin, sodium chloride, ammonium chloride and the like. There is, or preferably, a mixture of this inorganic phase change agent and sodium chloride, and the thickener is selected from sodium polyacrylate, pralidoxime methyl iodide, carboxymethyl cellulose, and carbomer (carboxyvinyl polymer). And at least one crosslinking agent, and the crosslinking agent is borax, N,N′-methylenebisacrylamide, and, for example, preferably aminopropyltriethoxysilane, glycidoxycarbonyltrimethoxysilane, methacryloxypropylmethoxysilane, At least one selected from silane coupling agents such as vinyltriethoxysilane, indolepropyltrimethoxysilane, ethylenediaminepropyltriethoxysilane, ethylenediaminepropylmethyldimethoxysilane, etc., and the curing agent is selected from aluminosilicate series. At least one of the above (preferably sodium aluminosilicate), the suspending agent consists of fumed silica, and the dispersant is, for example, preferably phosphate, (hexa)metaphosphate, polymetaline. It is a powdered inorganic material consisting of at least one selected from sodium acid salt, silicate, carbonate and the like, and the antifungal agent comprises various antifungal agents, preferably zinc oxide.

The outer sheet (the front and back materials of the cooling mat) for filling the middle material has a high cooling effect, is not easily damaged, is highly waterproof, and has high mold resistance, for example, 100% polyester. It is preferably composed of a material or 100% polyvinyl chloride material. Then, the peripheral edges of the front and back surface materials are welded by a predetermined heat (heat of the temperature for welding the material), and all the peripheral edges of the sheet are firmly fixed to be completely waterproofed. .. The curing prevention cooling sensation mat of the present invention is composed of a plurality of compartments, and when the mat is divided into a predetermined number, like the edge portion around the material, Each chamber is constructed by welding with the heat of. Therefore, it is possible to fabricate a durable mat that will not fall apart even if it is washed with water many times.

By using the anti-hardening agent, for example, an aluminosilicate (eg, preferably sodium aluminosilicate) or the like weakens the coupling effect between particles of each component, and homogenizes and stabilizes the crystal. Is possible. Further, the aluminosilicate adheres to the main component material and can fulfill the purposes of fluidity and hardening prevention of the simple substance by the following means.

(1) Physically fulfill the function of blocking between the main component materials. Since the adhesion of the aluminosilicate itself is small, the main component materials are weakly connected at the same time, and it is difficult to continue the connection and form a large crystal. When the aluminosilicate adheres to the surface of the main component material, it reduces the frictional force on the surface of the main component material, improves the fluidity of the main component material, and makes the crystals themselves more uniform.

(2) The moisture absorption competition between the aluminosilicate and the main component material reduces the tendency of the main component material to absorb and cure.

(3) The internal structure and interface of the crystal can be reduced during the crystallization process of the main component material. If the interface is small, the crystal structure between molecules can be easily broken, and as a result, it becomes difficult to form large crystals (lumps).

By using the suspending agent, for example, if fumed silica or the like having a strong surface adhesiveness is present on the surface of the molecule of the main material of the present invention, the adhesion between crystals is reduced, and a large lump of crystals is formed. Can be prevented.

By using an antifungal antibacterial agent, for example, an antibacterial effect can be obtained by zinc oxide or the like, the cooling sensitivity can be increased, and the heat absorption time can be extended. It should be noted that nanometer-class zinc oxide has high-efficiency activity, high absorption rate, strong antioxidative ability, safety stability, and antibacterial effect.

The water is not particularly limited as long as it is ordinary water, but distilled water is preferable.

As described above, according to the intermediate material filled in the anti-curing cooling mat of the present invention, the synergistic action of the anti-hardening agent, the suspending agent, and the dispersant is utilized, so that the particles of each component are The adhesive force can be improved and the hardening phenomenon of the intermediate material for the cooling mat can be prevented.

According to the present invention, the cooling sensation is improved and the cooling sensation duration time is extended by adjusting the ratio of sodium chloride. Thus, the freezing point of the main component material can be lowered by adjusting the input amount of sodium chloride. That is, one of the component materials, sodium sulfate decahydrate, has a freezing point of 32°C, and the optimum human body surface temperature is usually 27 to 29°C. The addition of sodium chloride produces a eutectic mixture with sodium sulphate decahydrate, which can lower the melting point to 27-29°C. As a result, it is possible to immediately feel a cold sensation when the human body surface exceeds 27° C. instead of 32° C.

The intermediate materials obtained in the following Examples and Comparative Examples were divided into a total of 20 chambers (2 rows in length, 10 rows in width) in a 90×140 cm curing prevention cooling mat as shown in FIG. Each of the prepared chambers was filled with a mat having a size of 45×14 cm to prepare an anti-cooling cooling sensation mat.

Regarding the gel-like (gel-like) middle material to be filled in the anti-cooling cooling sensation mat of the present invention, first, water, a simple substance and a dispersant are put into a predetermined container, and preferably mixed for about 10 minutes. After that, a cross-linking agent was added, and preferably mixed for about 5 minutes, and then a thickener, an anti-hardening agent, an anti-settling agent, and an anti-fungal agent were added and mixed sufficiently. In the following Examples and Comparative Examples, the above components were mixed in this order, and a middle material was produced according to this process. All of these components were charged and mixed in an environment of room temperature (18 to 25° C.).

In this example, the following components were mixed at room temperature (18 to 25° C.) based on the above-described manufacturing process of the intermediate material to produce the intermediate material. Also in the following examples and comparative examples, the intermediate material was produced based on the same process. 75.0% by weight of a mixture of 55.0% by weight of sodium sulfate decahydrate, 32.0% by weight of polyethylene glycol, 6.0% by weight of sodium chloride and 7.0% by weight of paraffin wax, as a thickener. 0.5% by weight of sodium polyacrylate, 3.0% by weight of sodium aluminosilicate as a curing agent, and 6.5% by weight of borax as a cross-linking agent. 3.5% by weight of fumed silica as a suspending agent, 5.0% by weight of sodium hexametaphosphate (sodium polymetaphosphate) as a dispersant, 4.0% by weight of zinc oxide and 2.5% by weight of water as an antifungal agent.

In this case, as a comparison, the temperature distribution of the back was also analyzed and measured by thermography for a human body not using the anti-curing cooling mat. The results are shown in FIGS. 3(a) and 3(b). As is clear from FIG. 3(a) (60 minutes, without using the curing prevention cooling sensation mat), it can be seen that the human body surface temperature is high because there are many red portions, and FIG. 3(b) (60 minutes, As can be seen from the use of the curing prevention cooling sensation mat), there are almost no red parts, most of them are blue parts, and the existence of white parts shows that the human body surface temperature is low. Furthermore, the surface temperature change of the human body was measured for 70 minutes with and without the use of the anti-cooling cooling mat (FIG. 4). As a result, as is clear from FIG. 4, when not used (before use), the temperature rises from about 34° C. to about 40° C., and when used (after use), about 32° C. to 36° C. It only rose to. From this, the effect of being able to lower the human body surface temperature by about 3° C. or more can be achieved by using the anti-curing cooling sensation mat. With respect to the anti-curing cooling mat of this example, the relationship between the test time and the temperature of the mat itself (falling temperature) was observed and measured at a test environment temperature of 25° C. for 82 minutes. The results are shown in Table 1 below and graphically in FIG.
