摘　　要：纯聚酯体系常用的消光方法为填料消光、添加不相容物比如蜡粉消光、两种反应速度的粉末干混消光、添加消光剂消光等。这些消光方式都有其优点,但是都难以实现消光至10%以下、甚至是5%的光泽。只有环氧丙烯酸树脂消光才能实现<10%光泽且有很好的稳定性,但是有表面抗划伤性能差的缺陷。本文通过对丙烯酸树脂的选择、聚酯酸值与交联密度、填料、加入羟基聚酯与其相应固化剂等方面来改进丙烯酸树脂消光时出现的抗划伤性差的问题。The typical methods of matting for polyester systems are to add matting filler, or incompatible component(wax),to mix the powders with two reaction rate or add matting agent, etc.These matting methods have their advantages while are difficult to achieve less than 10% gloss, or even 5% gloss. Only acrylic matting agent can achieve less than 10% gloss and good stability but there is a defect of low surface scratch resistance. In this paper, the low scratch resistance of acrylic resin is improved by the selection of acrylic resin, polyester acid value and crosslinking density,fillers, addition of hydroxyl polyester and its corresponding curing agent.
