Abstract

The invention discloses a low-VOC foaming prime coat which is prepared from the following raw materials in parts by weight: 15-20% of PVC (polyvinyl chloride) copolymer resin, 5-7% of PVC blended resin, 32-36% of a filler, 24-28% of plasticizer, 3-5% of moisture absorbent, 1-4% of zeolite powder and 1-1.5% of tackifier, wherein the filler is calcium carbonate with the particle size of 10-20 microns and nano-scale calcium carbonate, the weight ratio of the calcium carbonate with the particle size of 10-20 microns to the nano-scale calcium carbonate is (2-2.5): 1. According to the foaming primecoat, the VOC content in a product is low, and the foaming prime coat is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of primers used in the automobile industry, in particular to a low-VOC foam primer. Background technique [0002] At this stage, the VOC content of primers used in the automotive industry is generally around the national standard critical value, which has a certain impact on the environment and the human body. At present, the VOC exceeding the standard of foaming primer is mainly due to the lack of decomposed organic substances or raw materials that absorb opportunities. How to solve the above technical problems is a matter for those skilled in the art to solve. SUMMARY OF THE INVENTION [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a low VOC foaming primer. [0004] In order to achieve the above-mentioned purpose, the technical scheme adopted in the present invention is: a low-VOC foaming primer, the foaming primer, in parts by weight, comprises ...
