Problems solved by technology

In the existing automotive interior material market, PVC artificial leather is only widely used in the epidermis of seat accessories due to poor wear resistance and poor air permeability. The main material area is often used in contact with body clothes, which is easy to wear and tear, so it is rarely used

Abstract

The invention discloses PVC artificial leather and a preparation method thereof as well as a car seat containing the PVC artificial leather. The PVC artificial leather comprises a base fabric layer, aPVC adhesive layer, a PVC foaming layer, a PVC dense layer and a surface layer which are arranged in order from bottom to top; the PVC adhesive layer is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride, 55-90 parts of a plasticizer, 1-5 parts of a calcium-zinc stabilizer and 1-3 parts of an AC foaming agent. The PVC artificial leather provided by the invention not only meets the technical standards of ordinary PVC leather, but also has the advantages of high wear resistance, environmental protection, and relatively high residual strength after punching, and meets the increasingly stringent requirements of the industry environmental protection regulations.

Description

technical field [0001] The invention relates to the technical field of automobile interior materials, in particular to a PVC artificial leather, a preparation method thereof, and an automobile seat containing the PVC artificial leather. Background technique [0002] At present, with the development of the economy, the demand for automobiles has further expanded, and at the same time, most consumers have further improved requirements for automobile quality and cost performance. Therefore, the competition among major OEMs is becoming more and more fierce, and the pressure to reduce costs is increasing. It has become a trend to use high-performance PVC leather to replace genuine leather on the A side of the seat, and to use microfiber materials to reduce costs. As an important visual part of the car, the car seat covered with PVC artificial leather is widely concerned by consumers for its mechanical properties, environmental protection performance and durability. [0003] For ...
