一种汽车内饰用软触弹性涂料
摘要：
本发明公开了一种汽车内饰用软触弹性涂料，由组分A、组分B、组分C制成，其中，所述组分A由以下重量份的组分制成：聚碳酸酯树脂A 40-50，聚碳酸酯树脂B 10-20，色粉5-20，分散剂5-10，弹性助剂A3-6，弹性助剂B2-4，流平剂1-3，紫外线吸收剂1-2，SiO2消光粉4-10，溶剂3-20；所述组分B为：HDI固化剂20-40，所述组分C为：稀释剂10-40；其中，所述聚碳酸酯树脂A的羟基值占固体成分的6.4wt％，质均分子量为500-550；所述聚碳酸酯树脂B的羟基值占固体成分的2.7wt％，质均分子量为1500-2000。本发明的汽车内饰用软触弹性涂料，可以同时达到美国通用GMW15516标准、PES11041耐DOP测试标准，并通过美国通用TYPE-F触感测试。
摘要（英）：

The invention discloses a soft touch elastic coating for automobile interior trims, wherein the soft touch elastic coating is prepared from a component A, a component B and a component C. The component A is prepared from the following components in parts by weight: 40-50 parts of polycarbonate resin A, 10-20 parts of polycarbonate resin B, 5-20 parts of a toner, 5-10 parts of a dispersant, 3-6 parts of an elastic auxiliary agent A, 2-4 parts of an elastic auxiliary agent B, 1-3 parts of a leveling agent, 1-2 parts of an ultraviolet absorbent, 4-10 parts of an SiO2 extinction powder, and 3-20 parts of a solvent; the component B is 20-40 parts of an HDI curing agent; the component C is 10-40 parts of a diluent. The hydroxyl value of the polycarbonate resin A accounts for 6.4 wt% of the solidcomponents, and the mass average molecular weight is 500-550; the hydroxyl value of the polycarbonate resin B accounts for 2.7 wt% of the solid components, and the mass average molecular weight is 1500-2000. The soft touch elastic coating for the automobile interior trims can simultaneously reach America general GMW 15516 standards and PES 11041 DOP-resisting test standards, and passes through America general TYPE-F touch tests.
