Abstract

The invention provides a method for preparing a high-adhesion wear-resistant paint used for polycarbonate. The method comprises the following steps: chlorinated polypropylene resin and modified resinare mixed, and stirred for 5-10 min, a BYK-163 type dispersant, a BYK-071 type antifoaming agent, dibutyltin dilaurate, cellulose acetate butyrate, corundum micro powder, ultrafine mica powder and a porous inorganic particle material are added under a stirring state, a sand milling machine is used for grinding the materials with fineness being less than or equal to 25 [mu]m, a solvent is added, the materials are heated to the temperature of 30-40 DEG C and is subjected to heating backflow for 1h, a silane coupling agent and a curing agent are added, cooling is carried out to room temperature,and the solvent is used for dilution. The paint has high adhesion, water resistance and excellent wear resistance.

Description

technical field [0001] The invention relates to the field of plastic coatings, in particular to a preparation method of a high-adhesion wear-resistant coating for polycarbonate. Background technique [0002] Polycarbonate (PC) is an important optical thermoplastic resin, which has the advantages of high transparency, good impact resistance, low density, low price and easy processing. Not only is it widely used in the production of transparent parts such as plates, eye lenses, and automobile windshields, but it has also been the first choice for high-speed aircraft in developed countries to improve the high-temperature resistance and bird impact resistance of transparent parts. However, PC also has the problems of low surface hardness, poor wear resistance, easy to scratch, chemical solvent resistance, crack growth resistance and poor weather resistance. The surface free energy of polycarbonate sheets is generally lower than that of metal surfaces, and even the surface tensi...
