Abstract

The invention discloses plastisol for an automobile chassis and a preparation method of the plastisol. PVC (polyvinyl chloride) paste resin and DOP (dioctyl phthalate) are taken as main materials, and the plastisol comprises components in parts by weight as follows: PVC paste resin, DOP, KCM-12, heavy calcium carbonate, a lead sulfate tribasic stabilizer, ZnO, low-molecule polyamide, nano activated calcium carbonate, CaO and a viscosity reducer.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for preparing automobile chassis plastisol with PVC paste resin as the main raw material. Background technique [0002] The application of adhesives in the automotive industry began in the 1940s. The purpose of developing adhesives at the beginning was to seal and prevent rust. Since the 1960s, with the improvement of the production process of the automobile industry and the need for comfort and luxury of cars, the automobile industry began to use a large number of sealants and adhesives. Before the 1980s, the sealants used in the automotive industry (mainly neoprene, nitrile rubber and alkyd resin) had the biggest disadvantage of containing benzene solvents, which were very toxic, affecting the health of operators and polluting the environment. In addition, during the curing process of the glue, due to the volatilization of the solvent, bubbles and volume sh...
