Abstract

The invention discloses lightweight artificial leather with wear-resistant skin for vehicles applied to automotive trims. The lightweight artificial leather comprises a surface treatment agent layer,a wear-resistant skin layer, a foaming layer, a glue layer and a base fabric layer distributed in sequence from top to bottom; the wear-resistant skin layer comprises 80-100 parts of PVC (Polyvinyl Chloride) resin powder, 50-100 parts of a plasticizer, 1-20 parts of a heat stabilizer, 0.01-20 parts of a flatting agent, 0.01-20 parts of an anti-aging agent and 0.1-30 parts of an anti-wear agent. The anti-wear agent comprises 5-50 parts of hollow glass beads, 5-50 parts of hollow ceramic micro-beads, 80-100 parts of an o-benzene plasticizer and 30-90 parts of polyvinyl chloride powder. By addingthe hollow micro-beads and performing dispersing treatment on the hollow micro-beads in advance, the technical problem that the conventional PVC artificial leather is not wear-resistant and high in density is solved, and the PVC artificial leather with high wear resistance and the lightweight characteristic is obtained.

Description

technical field [0001] The invention relates to the field of leather processing, in particular to a lightweight artificial leather for vehicles with a wear-resistant skin and a preparation method thereof. Background technique [0002] With the increase of population growth, environmental protection and social needs, the demand for artificial leather in contemporary society is increasing, and polyvinyl chloride (PVC) artificial leather, as the most widely used artificial leather, is widely used in automotive interior parts. Excellent product performance and appearance comparable to natural leather are favored by the public. Polyvinyl chloride (PVC) artificial leather is a composite material made by mixing polyvinyl chloride or other resins with certain additives, coating or pasting on the substrate and then processing it. It is similar to natural leather and has Soft, wear-resistant and other characteristics, it can be used to prepare various bags, car seat covers, car inter...
