Abstract

The invention provides a high-wear-resistance self-recovery rubber-feel plastic paint which comprises a main agent, a diluter and a curing agent, wherein the main agent comprises the following components in parts by weight: 15-17.5 parts of double-component polyurethane resin A, 15-17.5 parts of double-component polyurethane resin B, 5-10 parts of 10% drying agent solution, 6-7.5 parts of matting powder, 0.5-1 part of leveling agent, 0-2 parts of epoxy modified polysiloxane, 15-20 parts of ethyl acetate, 15-20 parts of butyl acetate and 10-15 parts of phenylmethane. The invention also provides a preparation method and construction method of the paint. The paint is applicable to coating cabinets made from plastics, such as ABS (acrylonitrile-butadiene-styrene), ABS+PC (polycarbonate), HIPS (high impact polystyrene) and the like. The paint has a favorable rubber feel, and also has high RCA resistance in common rubber paint. The paint can be widely used for coating interior decorative plastic parts of 3C (Computers / Communications / Consumer electronics) products and automobiles, has favorable appearance effect and touch effect, has the characteristics of low toxicity, low pollution and lower VOC (volatile organic compound) emission, and conforms to the international environmental-protection requirements.

Description

technical field [0001] The application of the present invention relates to a high wear-resistant and self-healing rubber-feeling plastic coating and its production and construction methods, belonging to the technical field of chemical coatings. Background technique [0002] Touch paint, also known as rubber paint and elastic paint, is sprayed on the surface of objects and is in a matte or semi-matte state. It feels very delicate and smooth, with elegant and solemn appearance, excellent scratch resistance, weather resistance and abrasion resistance. [0003] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. The functions of the topcoat and the primer are different. The topcoat is more focused on th...
