The invention relates to a scratch-resistant and wear-resistant high-strength PVC/ABS and PS/ABS double-layer composite automotive interior skin and a preparation method thereof. The interior skin comprises the following raw materials: 50-100 parts of PVC resin with the polymerization degree of 1300; 30 to 70 parts of ABS resin; 20-40 parts of powdered nitrile rubber; 1.5-3 parts of a PC/ABS alloy film; 5 to 20 parts of dioctyl sebacate; 50 to 75 parts of trioctyl trimellitate; 5 to 10 parts of antimony trioxide; 8-12 parts of zinc borate; 20 to 60 parts of filler; 10-15 parts of a calcium-zinc heat stabilizer; 0.4 to 0.6 part of an external lubricant; 0.5-1 part of an internal lubricant; 3-10 parts of a processing aid; and 1-5 parts of a matt agent. According to the invention, ABS is used as an adhesive, a benzene ring in ABS can be well combined with a benzene ring in PC, PC/ABS is used as a surface layer and is subjected to double-layer lamination with the PVC/ABS film, so that the surface hardness of a product is improved, the original physical and chemical characteristics are maintained, the scratch resistance of the automotive trim skin can be effectively improved, the process can be simplified, and the environmental pollution can be reduced.

    一种耐刮磨高强度PVC/ABS、PS/ABS双层复合汽车内饰表皮及其制备方法,内饰表皮的原料包括:聚合度为1300的PVC树脂50~100份;ABS树脂30~70份;粉末丁腈橡胶20~40份;PC/ABS合金薄膜1.5~3份;癸二酸二辛酯5~20份;偏苯三酸三辛酯50~75份;三氧化二锑5~10份;硼酸锌8~12份;填料20~60份;钙锌热稳定剂10~15份;外润滑剂0.4~0.6份;内润滑剂0.5~1份;加工助剂3~10份;雾面剂1~5份。本发明利用ABS作为粘合剂,ABS中的苯环能与PC中的苯环很好的相结合,利用PC/ABS为表层与PVC/ABS薄膜进行双层贴合来提高产品的表面硬度并保持原有物化特性,可有效提升汽车内饰表皮的耐刮痕性,并能简化工艺、减少环境污染。
