Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to an ultra-quick-drying aerosol stock solution composition for treating pet excrement. (Prior art and problems to be solved by the invention) The recent pet boom is astounding, and product development in the pet industry is remarkable and widely used in all fields such as clothing, food, housing, medicine, and entertainment. It extends to However, the development of products related to pet excrement is lagging behind, and although there are some related products for pets kept indoors, there is currently no product development at all for pets kept outdoors. Therefore, for example, despite the fact that leaving or insufficiently disposing of excrement from outdoor pets when taken out for play or walks is becoming a social problem, there is a need for a means to dispose of excrement quickly, easily, and hygienically. has not been developed yet. The present invention was made in view of the current situation, and is the first of its kind in this industry. Therefore, by applying the present invention to the excrement of outdoor pets, it is possible to eradicate the odor and to dispose of the excrement quickly, easily, with less disgust, and in a hygienic manner. An object of the present invention is to provide an aerosol coating composition. It should be noted that the composition according to the invention is completely different in its application and usage from the previously used aerosol paint sprays. (Means for Solving the Problem) According to the present invention, the above problem can be solved by adding solid resin and/or A concentrate composition formed by dissolving a highly nonvolatile resin, the resin being selected from the group consisting of polyethylene resin, polypropylene resin, polyamide resin, polybutadiene resin, acrylic resin, polystyrene resin, vinyl acetate resin, butyral resin, and petroleum resin. and the solvent is selected from the group consisting of halogenated hydrocarbons, hydrocarbons, ethers, esters, alcohols and ketones, and the neat composition has a This problem can be solved by an ultra-quick-drying aerosol stock composition characterized in that the ratio of the area of the formed suspended zone after 96 hours to the area of the dense zone is 0.9 or more. That is, when the ultra-quick-drying aerosol stock composition is sprayed onto excrement and applied, a dry coating is formed on the excrement in an extremely short period of time, making it possible to dispose of the excrement quickly and easily. In the present invention, the resin is swollen in a desired solvent,
By dispersing and minimizing the dissolution, the volatilization of the propellant and solvent is promoted the moment the resulting composition is sprayed, achieving ultra-quick drying properties. The resin used in the present invention is a solid resin, a highly nonvolatile resin, or a mixture thereof. By using such a resin, swelling in a solvent, dispersion, and minimal dissolution operations as described above become easy. solid resin is
Powders with a diameter of 10 μm or less are preferred. Further, the highly nonvolatile resin preferably has quick drying properties and requires a small amount of solvent. In the composition of the present invention, the resin is selected from the group consisting of polyethylene resin, polypropylene resin, polyamide resin, polybutadiene resin, acrylic resin, polystyrene resin, vinyl acetate resin, butyral resin and petroleum resin, and the solvent is halogenated hydrocarbon, selected from the group consisting of hydrocarbons, ethers, esters, alcohols and ketones. Acrylic, styrene and butyral are preferred. The content of synthetic resin in the composition is 6 to 60 wt%, preferably 15 to 40 wt%. When it is less than 6wt%, the formed film becomes thin and the film effect becomes poor. Moreover, if it exceeds 60 wt%, clogging of the aerosol contents is likely to occur and the price will increase. In the present invention, the affinity between the resin and the solvent is one of the important factors. In other words, when the affinity between the resin and the solvent is good, the volatilization of the solvent is slow and the desired composition cannot be obtained.On the other hand, when the affinity between the resin and the solvent is poor, the volatilization of the solvent is accelerated and the result is ultra-quick drying. Although neat compositions are obtained, problems arise in the sprayability of the composition and the desired adhesion to the coating. Therefore, in the present invention, a mixed solvent of a poor solvent and a true solvent is used as the solvent, and in this case, the ratio of the poor solvent to the true solvent to the resin is very important. Furthermore, the ratio also affects the storage stability of the aerosol product obtained using the composition. The types of poor solvent and true solvent are determined by the resin concerned. Specific examples of classification of poor solvents and true solvents for the resins are shown in Table 1.

【table】

[Table] The mixing ratio by weight of poor solvent to true solvent is from 10 to
90:90-10, preferably 40-80:60-20.
If the amount of the poor solvent is less than the above range, drying will be extremely slow, while if the amount is more than the above range, the spray mist will be coarse and the coating effect will be almost nil. For example, if we take acrylic resin as an example, it will be as follows. Poor solvent: n- of alcohol type and hydrocarbon type
Pentane, trichlorotrifluoroethane among halogenated hydrocarbons, etc. True solvents: halogenated hydrocarbons, hydrocarbons, ethers, esters, ketones, etc. In this case, the ratio of poor solvent to true solvent is particularly 50:
50 is preferred. The content of solvent in the composition is 20-90 wt%, preferably 25-85 wt%. If it is less than 20wt%, it will not be sufficient to swell, disperse, and dissolve the resin to a minimum, while if it is more than 90wt%, it will not dry very quickly, and the formed coating will sag, resulting in poor removability. . Furthermore, in the present invention, when the sedimentation curve of the aerosol stock composition is graphed, the isokinetic sedimentation curve, compression desorbing curve, and soft cake height curve indicate that it is formed when 96 hours have passed after the preparation of the stock solution composition. The ratio of the area of the suspended zone to the area of the dense zone is
It is good if it is 0.9 or more. This aerosol stock solution composition (Example 1)
Figure 1 shows the sedimentation rate plotted in a 50 c.c. candle bottle. The height (%) of the interface between the suspended part and the transparent part or the height (%) of the soft cake is plotted on the vertical axis, and the time (time) is plotted on the horizontal axis.
The curve showing the height of the boundary surface is the constant velocity sedimentation curve, the curve showing the height of the soft cake is the soft cake height curve, and the point after the point where the uniform sedimentation curve and the soft cake height curve touch (compression point) The curve showing the height of the boundary surface (height of the soft cake) is the compression dehydration curve. The area formed below the isokinetic sedimentation curve and above the soft cake height curve is defined as the suspended area, and the area formed below the soft cake height curve and below the optional compression dehydration curve is defined as the dense area. Note that the area after 96 hours is the area of each area 96 hours after preparation of the composition. If the ratio of the area of the suspension zone after 96 hours to the area of the dense zone is less than 0.9, it is undesirable because it tends to become a hard cake and has poor storage stability. The larger the area of the suspension zone, the less likely it will be a hard cake. Furthermore, a hard cake can also be easily formed when the resin is not dissolved at all. Therefore,
The mixing ratio of the poor solvent and the true solvent is an important factor in widening the suspension zone and stabilizing the precipitate as a soft cake. When the ultra-quick-drying aerosol stock composition according to the present invention was filled into an aerosol container and a storage stability test was conducted, it was found that the composition, which swelled, dispersed, and dissolved to a very small extent, did not separate easily and did not last for a long time. It was found that the suspended state was maintained. Even when the storage stability was tested for 3 months, it was found that the sediment did not get stuck in the hard cake, but was easily dispersed and mixed in the glass beads built into the aerosol container. In addition to the above-mentioned resin and solvent, the ultra-quick-drying aerosol stock composition of the present invention may contain coloring pigments, auxiliary agents, plasticizers, and the like. It is important to select coloring pigments that have good affinity with synthetic resins, solvents, plasticizers, etc. For example, for red, β-naphthol type (Lake Red C, D, 4R, permanent F4R, etc.), yellow So, azo type (Hansa Yellow 10G, 5G, G,
GR, benzine yellow G, etc.), green colors such as Diamond Green Lake, Heliogen Green G, Pigment Green B, etc., white colors such as titanium white, zinc white, lead white, etc., and black colors such as carbon black, aniline black, etc. I can do it. The content of the colored pigment in the composition is 1-
20wt%, preferably 5-10wt%. Any plasticizer may be used as long as it imparts plasticity to the formed coating film, and preferred are sorbitan fatty acid ethyl ether and phthalic acid diester. The content of plasticizer in the composition is 1 to 20 wt%, preferably 2 to 15 wt%. If it is less than 1wt%, the plasticity of the formed coating film will decrease, and if it is more than 20wt%, the tackiness of the coating film will increase, which is not preferable. Examples of auxiliary agents include anti-settling agents (white carbon, polyethylene wax, etc.) and deodorants (complex of ferric sulfate and ascorbic acid, limonene, etc.). The content of the adjuvant is 0.1-5wt%, preferably 0.5-3wt%. Meanwhile, a propellant is used to make the ultra-quick-drying aerosol stock composition into an aerosol product. The propellant is usually selected from dichlorodifluoromethane, monochlorodifluoromethane, dimethyl ether, liquefied petroleum gas, dichlorotetrafluoroethane, etc., which can be used as propellants, and each may be used alone or as a mixture. May be used. Aerosol products can be manufactured using the present aerosol stock composition according to any commonly used method. Examples of the present invention will be described below.
