一种变色人造革及其制备方法
摘要：
本发明涉及一种变色人造革，从上到下依次包括面层、变色层和发泡层，所述面层包括以下重量份原料制备而成：聚氨酯树脂100份和有机溶剂80-100份，所述变色层包括以下重量份原料制备而成：聚氯乙烯树脂100份、邻苯二甲酸二辛酯80-100份、碳酸氢钙40-60份、热稳定剂1-3份和PVC色浆3-5份，所述发泡层包括以下重量份原料制备而成：聚氯乙烯树脂100份、邻苯二甲酸二辛酯80-90份、填充剂60-70份、稳定剂2-3份和发泡剂3-4份。本发明还涉及一种变色人造革的制备方法。本发明提供的变色人造革具有大幅度提升变色人造革的整体结构的耐磨性能的优点。
摘要（英）：

The invention relates to allochroic artificial leather which sequentially comprises a surface layer, an allochroic layer and a foaming layer from top to bottom. The surface layer is prepared from, by weight, 100 parts of polyurethane resin and 80-100 parts of organic solvent; the allochroic layer is prepared from, by weight, 100 parts of polyvinyl chloride resin, 80-100 parts of dioctyl phthalate, 40-60 parts of calcium bicarbonate, 1-3 parts of heat stabilizers and 3-5 parts of PVC color paste; the foaming layer is prepared from, by weight, 100 parts of polyvinyl chloride resin, 80-90 parts of dioctyl phthalate, 60-70 parts of filling agents, 2-3 parts of stabilizers and 3-4 parts of foaming agents. The invention further relates to a preparation method of the allochroic artificial leather. The allochroic artificial leather has the advantages of significantly improving the wear-resisting property of the overall structure of the allochroic artificial leather.
