Polystyrene multicolor paint

Abstract

The invention relates to a polystyrene multicolor paint. The paint comprises the following raw materials in parts by weight: 100 parts of polystyrene, 5-15 parts of benzoyl peroxide, 20-40 parts of titanium dioxide, 35-45 parts of tricresyl phosphate, 10-30 parts of rosin size, 5-25 parts of propylene glycol butyl ether, 80-90 parts of deionized water, 15-35 parts of dibutyltin dilaurate, 10-20 parts of pigment, 25-35 parts of diethylenetriamine, 20-30 parts of phthalic acid dibutyl ester, 10-20 parts of precipitated barium sulfate, 8-10 parts of a plasticizer, 25-45 parts of butanediol, 10-20 parts of ethylene glycol monoethyl ether acetate, and 30-40 parts of polyurethane. After products are stirred, the products are uniform, an agglomerate phenomenon is avoided, paint films are scrubbing resistant, and after the paint films are scrubbed for 2500-3500 times, bottoms are not exposed; after the paint films are soaked in saturation calcium hydroxide for 2-4 days, the paint films do not bubble or drop, and after the paint films are soaked in the water with the temperature of 20 DEG C for 10-20 days, the paint films do not bubble, and powder does not drop from the paint films; the covering power is 200-300g / cm <2>; the paint films are flat and smooth, the color is uniform, and the paint can be widely produced and can be used for continuously replacing existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a polystyrene colorful coating. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives, viscous liquid prepared with organic solvent or rosin glue. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." The material coated on the surface of an ob...
