Problems solved by technology

[0007] Because the surface of the hard interior is hard, the texture is not as good as the soft interior. The soft interior gives people a comfortable and luxurious feeling, and also has the function of absorbing collision energy and noise, so it is mostly used in mid-to-high-end cars. In recent years, more

Abstract

The invention relates to an auto-interior PVC new composite material and a production method thereof. The material is characterized in that the material comprises a foaming layer and a rind arranged on the foaming layer; the rind is characterized by composing the following components in parts by weight: 100 parts of more than one of PVC and ultra-high molecular weight ethylene-vinyl chloride copolymer, 5-30 parts of impact modifier, 1-5 parts of stabilizer, 40-80 parts of plasticizer and a defined amount of pigment; the degree of polymerization of the ultra-high molecular weight ethylene-vinyl chloride copolymer can reach 2800, the impact modifier is more than one of ABS, MBS and ASA. Compared with the prior art, the invention has the advantages of low cost, favorable weather resistance and good texture.

Description

technical field [0001] The invention relates to a composite plastic and its manufacturing process. Background technique [0002] The scope of automotive interiors is mainly composed of instrument panels, door panels, roofs, seat cushions, wood grain finishes, sun visors, armrests, gear covers, etc. The material properties are very demanding, and they have high requirements for temperature resistance, weather resistance, odor, appearance, Wear resistance and other requirements are very strict. Among them, the structures of instrument panels, door panels, armrests, roofs, and seat backs are basically the same. Taking instrument panels as an example, they can be divided into hard instrument panels and soft instrument panels according to their surfaces. [0003] The hard instrument panel refers to the instrument panel with a hard surface, usually a single-layer structure directly injection molded (very few use a multi-layer structure), mostly using modified PP or TPO materials,...
