Problems solved by technology
[0002] Existing toys obtained by polymer injection molding can be pasted with photo paper stickers, but due to long-term use, the surface of the toy is easily damaged and the adhesion between the two is weakened
The adhesion between the toy and the sticker can be enhanced by coating some tackifying materials on the surface of the toy. However, traditional tackifying materials generally have the problem that the viscosity drops significantly after repeated use, and they are not suitable for washing.

preparation example Construction
[0046] The invention also provides a method for preparing a coating material. The finished color paste and the finished varnish are prepared respectively, and the fillers are added for dispersion.
[0047] In a specific example, the finished color paste and the finished varnish are prepared respectively, and the filler is added for dispersion. Specifically, the dispersion time is 0.1-0.8 hours, and the dispersion speed is 1300-1500 r / min.
[0048] In a specific example, the pigment, methyl methacrylate-butyl methacrylate copolymer, cyclohexanone and butyl acetate are mixed and dispersed to obtain a semi-finished color paste, and the semi-finished color paste is ground as a finished color paste. The dispersion time is 0.2 to 0.6 hours, the dispersion speed is 1300 to 1500 r / min, and the grinding times are 3 to 4 times. Preferably, the particle size of the finished color paste after grinding is 7 to 9 μm, which is more conducive to subsequent dispersion.

Abstract
The invention discloses a coating material and a preparation method and application thereof. The coating material, in parts by weight, includes 10-30 parts of finished color paste, 70-90 parts of finished varnish, and 1-3 parts of filler; the finished varnish, in parts by weight, includes petroleum 10-25 parts of resin, 25-45 parts of block copolymer, 1-3 parts of methyl methacrylate-butyl methacrylatecopolymer, 3-10 parts of polyketone resin, 2-5 parts of ethyl acetate, two 3-6 parts of propylene glycol butyl ether, 1-14 parts of cyclohexane 1.2-diisononyl dicarboxylate, 1.5-6.5 parts of first auxiliary agent, and 3-6 parts of solvent; the finished color paste is calculated in parts by weight , including 5-7 parts of pigments, 4-8 parts of methyl methacrylate-butyl methacrylatecopolymer, 6-10 parts of butyl acetate, and 6-10 parts of cyclohexanone. The above-mentioned coating material can be prepared as a coating glue, and can also be coated on toys or handicrafts, which can keep the stickiness and can be washed with water after repeated use with photo paper stickers.
Description
technical field [0001] The invention relates to the field of coatings, in particular to a coating material and a preparation method and application thereof. Background technique [0002] The existing toys obtained by polymer injection molding can be pasted with photo paper stickers, but due to long-term use, the surface of the toy is easily damaged and the adhesion between the two is weakened. The adhesion between the toy and the sticker can be enhanced by coating some tackifying materials on the surface of the toy. However, the traditional tackifying materials generally have the problem that the stickiness decreases significantly after repeated use, and they are not suitable for washing. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a coating material and a preparation method and application thereof in order to satisfy the requirement that the stickers such as toys and photo paper stickers remain sticky and can be washed with water after repe...
