Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an ultra-quick-drying aerosol stock composition for treating bed excrement.

(Prior art and problems to be solved by the invention) The recent betting boom has been spectacular, and product development in the betting industry has been rapid and widespread in all fields such as clothing, food, housing, medicine, and entertainment. It extends to However, the development of products related to bed excrement has been delayed, and although there are some related products for indoor beds, there is currently no product development at all for outdoor beds. Therefore, for example, although the neglect or insufficient disposal of excrement from outdoor pets when taken out for play or walks is becoming a social problem, there is no means to dispose of excrement quickly, easily, and hygienically. It has not been developed.

The present invention was made in view of the current situation, and is the first of its kind in this industry.

Therefore, the present invention provides an aerosol that can be applied to the excrement of outdoor pets to eradicate the bad odor thereof, and to dispose of the excrement quickly, conveniently, and hygienically with less disgust. The purpose is to provide a coating composition.

It should be noted that the composition according to the present invention has a completely different use and function from conventionally used aerosol paint sprays.

(Means for Solving the Problems) According to the present invention, the above problems can be solved by adding solid resin and/or The ratio of the area of the suspended zone after 96 hours to the area of the dense zone formed by the isokinetic sedimentation curve, compression dewatering curve and soft cake height curve of the solution obtained by dissolving the highly non-volatile resin is This problem can be solved by using an ultra-quick-drying aerosol stock composition characterized by a drying temperature of 0.9 or more.

That is, when the ultra-quick-drying aerosol stock composition is sprayed onto excrement and applied, a dry pattern is formed on the excrement in a very short period of time, making it possible to dispose of the excrement quickly and easily.

In the present invention, by swelling, dispersing, and dissolving the resin in a desired solvent to a minimum, the volatilization of the propellant and solvent is promoted and ultra-quick drying properties are achieved the moment the resulting composition is sprayed.

The resin used in the present invention is a solid resin or a high non-volatile resin or a mixture thereof. By using such a resin, swelling, dispersion, and minimal dissolution operations in a solvent as described above become easy. The solid resin is preferably a powder of 10 μm or less. Further, the highly nonvolatile resin preferably has quick drying properties and requires a small amount of solvent.

As the resin, synthetic resins are generally used, such as polyethylene, polypropylene, polyamide, butadiene, acrylic, polystyrene, vinyl acetate, butyral, polyester, petroleum resin, and the like. Acrylic, styrene and butyral are preferred. The content of the synthetic resin in the composition is 6 to 5 Qwt%, preferably 15 to 40Wt%. When it becomes less than 5wt%,
The formed film is not thin and the coating effect is poor. Also, 6
When it exceeds 0wt, clogging of the aerosol contents is likely to occur, and the price becomes high.

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 resin are shown in Table 1, but the present invention is not limited to these combinations.

Mixing ratio by weight of poor solvent to true solvent is %10-90:9
The ratio is 0 to 10, preferably 40 to 80:60 to 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, taking acrylic resin as an example, it is as follows.

Poor solvents: alcohols, n-tanthane among hydrocarbons, 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 preferably 50:50.

The content of solvent in the composition is 20-9 Q wt%, preferably 25-85 wt%. If it is less than 2Qwt%, it will not be sufficient to swell, disperse, and dissolve the resin to a minimum, while if it is more than 9Qwt%, it will not dry quickly, and the formed coating will sag, resulting in poor peelability. is inferior.

Furthermore, in the present invention, a isokinetic sedimentation curve when graphing the sedimentation curve of the present aerosol stock composition.

It is preferable that the ratio of the area of the suspended zone after 96 hours and the area of the dense zone formed by the compression desolvation curve and the soft cake height curve is 0.9 or more.

Fig. 1 shows a plot of the sedimentation rate of this aerosol stock solution composition f 50 cc placed in a 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.
Take. The curve showing the height of the interface is the constant velocity sedimentation curve, the curve showing the height of the soft cake is the soft cake height curve, and the point where the uniform sedimentation curve and the soft cake height curve touch (
The curve showing the height of the interface after the compression point (the height of the soft cake) is the compression degasification 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 compression desolvation contamination that may exist is defined as the dense area. . Incidentally, 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 carried out, it was found that the composition, which swelled to 1 level and dissolved to a minimum, did not separate easily and remained stable 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.

The ultra-quick-drying aerosol stock composition of the present invention includes:
In addition to the resin and solvent mentioned above, coloring pigments, auxiliary agents, plasticizers, etc. can be included.

It is important to select coloring pigments that have good affinity with synthetic resins, solvents, plasticizers, etc. For example, for red, β-naphthol type (Lakeretsu) C, D, 4R, permanent F4R, etc.) , For yellow, azo type (Hansa Yellow 10G, 5G).

Green colors include Diamond Green Lake, Heliodan Green G1 Pigment Green B, etc. White colors include Titanium White, Zinc White,
Examples of black colors such as lead white include carbon black and aniline black. The content of the colored pigment in the composition is 1 to 20 wt, preferably 5 to 1 Qw.
t%.

Any plasticizer may be used as long as it imparts plasticity to the formed coating film, and preferred examples include nrubitan fatty acid ester,
Coated with phthalic acid diester. The content of plasticizer in the composition is 1 to 20 wt%, preferably 2 to 15 wt%.
It is. If it is less than 1 wt%, the plasticity of the formed coating film will decrease, and if it is more than 20 wt%, the adhesiveness of the film will be undesirable.

Examples of auxiliary agents include anti-settling agents (white carbon,
polyethylene wax, etc.), deodorants (complex of ferric sulfate and ascorbic acid, limonene, etc.). What is the content of adjuvants?

0.1-5 wt%, preferably 0.5-3 wt%
It is.

Meanwhile, a propellant is used to make the ultra-quick-drying aerosol stock composition into an aerosol product. As a propellant, dichlorodifluoromethane, which can usually be used as a propellant,
It is selected from monochlorodifluoromethane, dimethyl ether, liquefied petroleum gas, dichlorotetrafluoroethane, etc., and each may be used alone or in a mixture.

Aerosol products can be manufactured using the present aerosol stock composition according to any commonly used method.
