Problems solved by technology

However, the PVC surface is treated with a coating layer to form a protective layer on the PVC surface, but this method can only indirectly solve the wear-resistant problem of PVC leather for a short time, and cannot fundamentally solve the defect of poor wear resistance of PVC leather. And the wear-resistant protective layer formed by the coating agent will gradually fail over time, which will directly lead to the wear and tear of PVC leather or genuine leather.

Abstract

The invention discloses PVC wear-resistant leather and a preparation method thereof. The PVC wear-resistant leather is prepared from the following raw materials in parts by weight: 50 to 70 parts of PVC resin, 1 to 3 parts of methyl triethyl silane, 10 to 20 parts of epoxidized soybean oil, 1 to 5 parts of polyurethane, 2 to 4 parts of tributyl citrate, 10 to 15 parts of modified aluminum oxide, 3 to 7 parts of silicon carbide, 1 to 3 parts of antistatic agent, 5 to 8 parts of wear-resistant agent and 1 to 5 parts of foaming agent, and the wear-resisting agent is polyvinyl chloride powder. The components of the raw materials cooperate with one another, the preparation method is combined, compared with common PVC leather, the finally prepared PVC leather is soft in hand feeling and has excellent wear resistance and aging resistance, and the preparation method is simple, easy to operate, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a PVC wear-resistant leather and a preparation method thereof. Background technique [0002] Leather is mainly used for car seat surfaces, armrest surfaces, etc. in automotive interiors. The outer surfaces of dashboards, steering wheels, and interior walls of compartments in some high-end cars are also covered with leather. The leather used in automotive interiors is mainly divided into genuine leather, artificial leather, and suede. Compared with artificial leather made of chemical fiber materials, leather interiors are soft, smooth and smooth, and have excellent tensile strength. They are mostly used for high-end luxury products. Inside the car model. Artificial leather includes PVC leather, PU leather, microfiber PU leather, etc. It is an industrial product produced by coating different fiber fabrics with different coating materials. Among them, polyvinyl chloride...
