摘要：以饱和聚酯树脂A和苯代三聚氰胺甲醛树脂为主要成膜物制备了汽车中涂漆。讨论了氨基树脂、聚酯树脂、填料、助剂和有机溶剂等对涂料性能的影响。结果表明，当聊(饱和聚酯树脂A)：m(苯代三聚氰胺甲醛树脂)=36：18，W(羟基聚酯树脂B)=3‰m(碳酸钙)：m(滑石粉)=5：5，w(附着力促进剂)=1％，采用丙烯酸类流平剂，选择适宜的有机溶剂时，得到了与底、面漆涂层配套性及综合性能良好的汽车中涂漆。 关键词：汽车；中涂；聚酯氨基漆；树脂；流平剂；溶剂 中图分类号：TQ633．52 文献标志码：A 文章编号：1004—227X f20091 02—0056—04 Preparation of high·-performance polyester--amino automotive intermediate paint／／SHEN Qiu—wang*，LIU Zhong，ZHOU Rong—hua，CUI Yue—song Abstract：A polyester．amino automotive intermediate paint was prepared by using saturated polyester resin A and benzene．substituted melamine formaldehyde resin as main film—forming materials．The effects of amino resin，polyester resin，fillers，additives and organic solvents on the properties ofpaint were studied．The experimental results indicated that the polyester—amino automotive intermediate paint prepared with 3％hydroxyl polyester resin B and l％adhesion． promoting agent by using acrylic leveling agent and a proper organic solvent at a mass ratio of saturated polyester resin A to benzene—substituted melamine formaldehyde resin 36：1 8 and a mass ratio of calcium carbonate to talcum powder 5：5 shows good comprehensive performance and matches well with primer and topcoat layers． Keywords：automotive；intermediate coatin9；polyester． amino paint；resin；leveling agent；solvent First-author’s address：Shenzhen Tonge Coatings Technology Development Company Ltd．，Shenzhen 5 1 8 1 22， China 1 前言 汽车中涂漆是介于底漆与面漆之间所用的涂料，它主要具有以下特性： (1)与底、面漆涂层配套性好，涂层间的结合力强，硬度配套适中，不被面漆的溶剂咬起。 |
