Problems solved by technology

Since plastic products are insulators, they are prone to static electricity, which leads to poor coating effect on the surface of the paint, and the performance of the paint film is average.
In addition, the existing plastic paint has average adhesion on the plastic surface, and its coating process is two coats of primer and top coat, which is costly.

Abstract

The invention provides a plastic paint and a preparation method thereof. The plastic paint is composed of the following raw materials in parts by weight: 50-60 parts of acrylic resin, 10-15 parts of filler, 2-5 parts of auxiliaries, 7-10 parts of pigment, 1-3 parts of curing agent, 5-10 parts of graphene dispersion liquid, 0.5-1 part of fatty alcohol phosphate diethanolamine salt, and 15-20 parts of solvent. The plastic paint prepared by the invention has the features of being high in rigidity, good in glossiness, and strong in adhesive force, convenient for construction, free from primer painting, and can be extensively applied to the product coating of the plastic substrate.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a plastic paint and a preparation method thereof. Background technique [0002] In recent years, plastic products have been widely used in industrial products. Plastics are light in weight, excellent in corrosion resistance, poor in heat transfer and electrical conductivity, and are easy to press into devices with complex shapes. In terms of product structure, it can replace some non-ferrous metals and light metals. In order to eliminate the pressing marks and uneven color on the plastic surface, it is often necessary to paint the plastic surface. Coating can both improve the appearance and prolong the life of the plastic. Since plastic products are insulators, they are prone to static electricity, which leads to poor coating effect of paint on the surface, and the performance of the paint film is average. In addition, the existing plastic paint has average adhesion on the p...
