摘要： 为解决亚黑 PU涂料抗刮性能差的问题，根据汽车内饰涂料的特点及要求，通过筛选不同的羟基丙烯酸树脂、添加剂，并对各物料配比进行合理化设计，最终采用了中羟丙烯酸树脂与改性的功能树脂混拼，并搭配消光粉、镁强粉、蜡粉、蜡浆等，研制了一种具有良好抗刮性能的汽车内饰单涂亚黑 PU涂料。对涂膜的综合性能进行了测试，结果显示：制备的单涂亚黑 PU涂料涂膜综合性能优良，在抗刮划方面的效果理想，适合作为汽车内饰用漆推广应用。

Abstract: To solve the problem of lower scratch resistance of matte black PU coatings， according to the characteristics and quality demand for automotive interior parts coatings，an excellent anti-scratch single-coat matte black PU coatings for automotive interior parts was developed by selection of different hydroxy acrylic resins，suitable additives and optimized formulation design，which was formulated with a blended binder of medium hydroxyl value acrylic resin，and a specific functional resin and mixed with matting agents，magnesium powder，wax etc.The overall performance of the new coatings was tested.The results showed that the matte black PU coatings developed provided better comprehensive performance， especially the scratch resistance. It could be scaled up for further applications for automotive interior parts.
