MULTI-LAYER SHEET MATERIAL AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a multi-layer sheet material, which contains at least one cover layer made of plasticizer-containing polyvinyl chloride and at least one coating facing outward on the cover layer. The invention further relates to a method for producing the multi-layer sheet material and to an interior trim part made of a sheet material for a vehicle. In order to solve the goal conflict between grain distortion of the surface during deep drawing and discoloration of the surface of the sheet material, the cover layer contains 50 to 100 wt% of at least one polyvinyl chloride and 0 to 15 wt% of at least one cross-linking aid, which is suitable for irradiation cross-linking, and a calcium hydroxide stabilizer and/or a Ca/Zn stabilizer, which has 0.5 to 10 wt% of calcium and 0.5 to 10 wt% of zinc, and at the same time the multi-layer sheet material is irradiation cross-linked.
