JP5730515B2 - Water-absorbing antibacterial deodorant composition and rug to which the same is applied - Google Patents

Description

The present invention relates to carpets and mats laid on the floors of buildings and corridors, automobiles and trains, airplanes, especially entrance mats, carpets and foot-wiping mats laid in bathrooms and bathrooms, and kitchens. The present invention relates to a water-absorbing and antibacterial deodorant composition applied to uses such as kitchen mats and toilet mats that are easily wetted with water and easily generate bad odors, and a rug to which the same is applied.

Specifically, a temperature-sensitive water-absorbing polymer capable of quickly absorbing and holding water and releasing the absorbed water is employed, and after the temperature-sensitive water-absorbing polymer absorbs water, The present invention relates to a water-absorbing and antibacterial deodorant composition capable of effectively suppressing the growth of bacteria and the generation of bad odors associated with this until the drainage performance is exhibited , and a rug to which the same is applied.

  Conventionally, entrance mats are often laid at the entrances of public facilities such as hotels and theaters. When it rains, many users go in and out through the doormat, so the doormat contains a lot of water, and when the user steps on the doormat, the user may get wet. For this reason, there was also the trouble that the doormat had to be replaced frequently. In addition, there are many entrance halls covered with marble and so on in the back of the entrance, and there was a danger that a user who had wet his feet would fall in the entrance hall.

  On the other hand, rugs such as carpets and foot mats laid in bathrooms and bathrooms must be removed and dried each time they get wet with water. It became a hotbed and caused odors.

  Furthermore, in the case of a rug such as a toilet mat, since it is used on the assumption that it becomes wet with urine, there is a problem that it must be frequently cleaned. If left wet, a bad odor was generated, causing discomfort to the user.

  Under such circumstances, a rug using a water-absorbing material made of an inorganic material such as zeolite or silica gel or a water-absorbing material made of a water-absorbing resin has been proposed. However, in such a rug, in order to increase the water absorption, when the amount of the water absorbing material is increased, the water absorbing material absorbs water and swells to lower the strength, and conversely to increase the strength as the rug. When the amount of the water absorbing material is reduced, there is a problem that sufficient water absorption cannot be obtained.

  Then, the rug which has sufficient water absorption and intensity | strength has come to be proposed (for example, refer patent document 1). This rug is characterized in that a stretchable nonwoven fabric layer having an elongation of 50% or more is laminated and partially integrated on at least one surface of a water absorbent nonwoven fabric layer composed of superabsorbent fibers having a water absorption of 10 g / g or more. It is what.

  However, in this rug, if the amount of water absorption reaches saturation, it does not have a function of discharging and releasing the retained water, so it becomes ineffective and must be replaced. Moreover, when pressure such as being stepped on is applied, there is a problem in that a phenomenon in which the absorbed water reverts also occurs.

  Therefore, a temperature-sensitive water-absorbing polymer (see, for example, Patent Document 2) having a function capable of quickly absorbing and holding water and releasing the water once absorbed is known. Consider adopting rugs instead of water-absorbing polymers.

  The temperature-sensitive water-absorbing / draining polymer exhibits water-drainage only when the temperature reaches the temperature-sensitive point after absorbing and holding moisture. For this reason, it is expected that the rug containing the polymer that has absorbed water until it reaches the temperature sensing point becomes a hotbed of bacteria and a source of malodor. In particular, when applied to a rug placed in an isolated room such as an automobile or a train, bad odor damage is considered to be significant.

FIG. 1 shows an antibacterial deodorant containing a water absorbing / draining solvent solution containing a temperature sensitive water absorbing / draining polymer having a temperature sensitive point of 10 to 45 ° C. constituting the water absorbing / draining antibacterial deodorant composition of the present invention. The spray apparatus which stored the solvent liquid is shown.

Examples of the solvent component that constitutes the water-absorbing solvent solution include at least one selected from water, lower alcohols such as methanol, ethanol, propyl alcohol, and isopropyl alcohol, or mixtures thereof. Among them, an aqueous ethanol solution having a blending ratio of water / ethanol (weight ratio) = 95/5 to 30/70 is preferable from the viewpoints of safety, availability, and price. Using this mixed solvent component, after the intake aqueous antimicrobial liquid deodorant composition is applied to the rug, dried in a short time, since the odor is not also strongly preferred because there is no possibility that an adverse effect on the surrounding environment during use .

  The water-absorbing polymer contained in this solvent component has good handleability and easy control of water-absorbing / draining properties. It uses a temperature-sensitive water-absorbing polymer with the function of changing and draining. Further, the temperature-sensitive water-absorbing / draining polymer may be anything as long as it has a temperature-sensitive point in the temperature range of 10 to 45 ° C, but a polymer having a temperature-sensitive point of 35 ° C is more preferable.

  A specific example of the temperature-sensitive water-absorbing polymer is a polymer obtained by polymerizing at least one of N-substituted (meth) acrylamide and N, N-substituted (meth) acrylamide in the presence of a crosslinking agent as a polymerization component. It is preferable that it is. By using these monomers, it is possible to obtain a resin that repeatedly absorbs and discharges water sensitively to temperature changes.

  Specific examples of N-substituted (meth) acrylamides include N-ethyl (meth) acrylamide, N-isopropyl (meth) acrylamide, N-isobutyl (meth) acrylamide, N-cyclohexyl (meth) acrylamide, N-phenyl (meth) ) Acrylamide, N-benzyl (meth) acrylamide, N-isopropoxy (meth) acrylamide and the like. In the present invention, N-isopropyl (meth) acrylamide is particularly preferable.

  Specific examples of N, N-substituted (meth) acrylamide include N, N-diethyl (meth) acrylamide, N-ethyl-N-methyl (meth) acrylamide, N, N-diisopropyl (meth) acrylamide and the like. . In the present invention, N, N-diisopropyl (meth) acrylamide is particularly preferable.

  The content of the temperature-sensitive water-absorbing polymer in the water-absorbing solvent solution is not particularly limited, but is preferably 1 to 30% by weight in order to ensure sufficient temperature-sensitive water-absorbing property and good dispersibility.

The phthalocyanine compound contained in the antibacterial deodorant solvent solution is represented by the following chemical formula 2, and M in the formula is a metal selected from iron, manganese, titanium, vanadium, nickel, copper, and tungsten. .

  Among the phthalocyanine compounds, those in which a copper complex is formed are preferable in terms of excellent antibacterial properties and deodorizing properties. Although it does not specifically limit as content of the phthalocyanine compound in an antibacterial deodorant solvent liquid, In order to ensure sufficient antibacterial deodorant property and favorable dispersibility, 1 to 30 weight% is preferable.

The solvent component constituting the antibacterial deodorant solvent solution is the same as the solvent component constituting the water-absorbing and draining solvent solution described above, water, lower alcohol such as methanol, ethanol, propyl alcohol, isopropyl alcohol, or a mixture thereof. The at least 1 sort (s) chosen from the inside can be mentioned. Among them, an aqueous ethanol solution having a blending ratio of water / ethanol (weight ratio) = 95/5 to 30/70 is preferable from the viewpoints of safety, availability, and price. Using this mixed solvent component, after the intake aqueous antimicrobial liquid deodorant composition is applied to the rug, dried in a short time, since the odor is not also strongly preferred because there is no possibility that an adverse effect on the surrounding environment during use .

Each of the water-absorbing solvent solution and the antibacterial deodorant solvent solution may further contain a binder component. In this case, the intake and exhaust aqueous antimicrobial liquid deodorant composition when sprayed on rugs, since temperature sensitive intake aqueous polymer and a phthalocyanine compound via a binder component on the fiber surface constituting the rug is attached, using the rug At this time, it is possible to prevent the temperature-sensitive water-absorbing and draining polymer and the phthalocyanine compound from easily falling off, and there is an advantage that the temperature-sensitive water-absorbing and drainage properties and antibacterial deodorizing properties can be secured for a long time.

  The content of the binder component contained in the water-absorbing solvent solution and the antibacterial deodorant solvent solution is not particularly limited, but if the content is too large, the temperature-sensitive water-absorbing polymer or phthalocyanine compound may be added depending on the binder component. It will be covered, and sufficient temperature-sensitive water-absorbing and drainage properties and antibacterial deodorizing properties cannot be obtained. On the other hand, when the content of the binder component is small, the adhesion of the temperature-sensitive water-absorbing polymer or phthalocyanine compound to the fiber surface constituting the rug through the binder component is weakened. As content of a binder component, 1 to 30 weight% is preferable.

In addition, in the water- absorbing and drainage solvent liquid and the antibacterial deodorizing solvent liquid constituting the water-absorbing and antibacterial deodorant liquid composition , pigments, thickeners and the like may be blended as desired. A glaze, a disinfectant, etc. can also be mix | blended.

Moreover, each of the water-absorbing and drainage solvent liquid and the antibacterial deodorant solvent liquid constituting the water-absorbing antibacterial deodorant liquid composition is in the form of an emulsion, suspension, and aerosol so that it can be sprayed using a spray device described later. Can be prepared.

Next, a spray device (hereinafter simply referred to as a device) used when applying the above-described water- absorbing and antibacterial deodorant composition to a rug will be described. As shown in FIG. 1, the apparatus 10 includes a spray main body 11, a spray container 12, a suction pipe 13, and a trigger 14.

The spray container 12 is an antibacterial solution containing a water absorbing / draining solvent solution containing a temperature sensitive water absorbing / draining polymer X having a temperature sensitive point of 10 to 45 ° C. constituting the water absorbing / draining antibacterial deodorant composition, and an antibacterial solution containing a phthalocyanine compound Y. The deodorant solvent liquid is stored in separate storage portions 12a and 12b, respectively. For this reason, the phthalocyanine compound is not agglomerated by the temperature-sensitive water-absorbing and draining polymer, and there is no fear that the function of the phthalocyanine compound will not be sufficiently exhibited due to aggregation.

  In the liquids of the storage portions 12 a and 12 b of the spray container 12, distal ends 13 a and 13 b of a bifurcated suction pipe 13 are arranged, and a branch pipe is formed at the proximal end portion of the suction pipe 13. Are combined into a liquid feed path (not shown) connected to the spray nozzle 15 in the spray body 11 in a mixed state.

  Then, by rotating the trigger 14 that is rotatably mounted on the spray body 11, a cylinder and a piston (not shown) arranged in the spray body 11 are moved, and the suction in each of the storage portions 12a and 12b is moved. The drainage solvent liquid and the antibacterial deodorant solvent liquid are fed into a liquid feed path (not shown) and sprayed through the spray nozzle 15.

  By using this device 10, during storage, the water-absorbing and draining solvent liquid containing the temperature-sensitive water-absorbing and draining polymer and the antibacterial deodorizing solvent liquid containing the phthalocyanine compound are stored separately. The phthalocyanine compound is not aggregated by the temperature-sensitive water-absorbing and draining polymer.

Next, a rug sprayed with a water-absorbing antibacterial deodorant composition using the apparatus shown in FIG. 1 will be described. The rug 20 shown in FIG. 2 is a tufted carpet in which a pile yarn 23 is tufted on a base fabric 21, and a resin backing 22 is provided on the back surface thereof. A temperature-sensitive water-absorbing polymer X and a phthalocyanine compound Y are attached to the surface of the base fabric 21 and the pile yarn 23 constituting the surface layer of the rug 20 sprayed with the water-absorbing antibacterial deodorant composition. Excellent water absorption and antibacterial deodorizing properties are imparted.

  In this rug 20, the temperature-sensitive water-absorbing polymer contained in the rug quickly absorbs and retains moisture on the rug 20 when wet with water. Once the water-absorbing temperature-sensitive water-absorbing polymer X has reached a predetermined temperature-sensitive point, it exhibits drainage, but until then, the phthalocyanine compound Y is associated with bacterial growth and accompanying this. The generation of bad odor is effectively suppressed.

The dry adhesion amount of the water-absorbing antibacterial deodorant composition to be sprayed on the rug 20 is not particularly limited. However, when sufficient performance is achieved and economy is considered, the adhesion amount at 1 to 100 g / m ² Is desirable.

The present invention is not limited to the above-described examples, and can be freely modified and implemented within the scope of the matters described in the claims .
