Abstract

The invention discloses a universal plastic primer for an automobile and a preparation method. The preparation method is characterized by comprising the following steps of weighing each raw material according to a proportion, adding modified thermoplastic acrylic resin into a dispersing agent, uniformly stirring, adding a pigment and a solvent while stirring, dispersing and grinding the mixture until the fineness is less than 20 microns, discharging the mixture, adding a leveling agent while stirring after cooling, and performing uniform stirring.

Description

technical field [0001] The invention relates to an automobile coating, in particular to a plastic primer that has good matching properties for plastic parts of different materials, good cooking resistance and resistance to alternating cold and heat, and belongs to the technical field of paint coatings. Background technique [0002] Automotive plastic coatings are similar to those used for other metal parts, and are also divided into primers, primers, varnishes or topcoats. marks and defects. With the rapid development of the automobile industry, the weight of automobiles tends to be lighter. Therefore, more and more plastic parts of various materials are applied to automobiles. In today's automotive plastic parts coating industry, the main resin in the formula is mostly polypropylene resin mixed with other raw materials, and processed according to conventional production processes. The problem is that this plastic primer cannot be applied to plastics of different materials...
