Problems solved by technology

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 at the same time. Parts, but made for plastic parts of a certain material, so it adds a lot of inconvenience to the parts when painting
In addition, the existing commercially available plastic primer products have weak adhesion and poor cooking resistance

Abstract

The invention relates to a general plastic auto primer and the preparation method thereof, pertaining to the coating technical field. The invention solves the universality of plastic auto primer and is characterized in that the primer comprises the components with certain weight portions, modified thermoplastic acrylic resin of 55-65wt portions, paint of 20-25wt portion, dispersion agent of 0.3-1.0wt portions, flow agent of 0.1-0.3wt portions and solvent of 15-30wt portions. The components are mixed and grinded for preparing the primer. The product of the invention is mainly characterized in that the product is applicable for primer coating of various auto plastic components and for plastic components of different materials, thereby, the product can reduce waste and trouble which are caused by frequent exchange of paint and dramatically improve work efficiency. In addition, the product of the invention has excellent boiling resistance and hot-cold alternation resistance. The product is proved to have better index of pencil hardness, adhesive, impact strength and water resistance, etc. over than the prior product and is expected to replace the prior plastic auto primer product.

Description

technical field [0001] The invention relates to an automobile paint, in particular to a plastic primer which has good compatibility with plastic parts of different materials, good cooking resistance and resistance to alternating cold and heat, and belongs to the technical field of paint and paint. Background technique [0002] Automotive plastic coatings are similar to those used for other metal parts. They 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 at t...
