摘　　要：采用乳液型丙烯酸树脂为主要成膜物,水稀释性羟基硅丙树脂为改性剂,甲基醚化三聚氰胺树脂为固化剂,制备了性能优异的水性氨基烘烤涂料。当固化剂与成膜树脂的质量比为1∶4,改性剂占成膜树脂总量的16.7%,颜料体积浓度为18%时,漆膜的硬度为2H,耐冲击性为50 cm,60°光泽>90,附着力1级,耐乙醇性好。并采用红外光谱分析了其固化前后分子结构及变化。The title waterborne acrylic -melamine coating with good performance has been prepared by use of acrylic resin emulsion as the main film - former, water reducible hydroxyl silicone - acrylic resin as modified agent and methylated melamine resin as curing agent. When the mass ratio of curing agent and film former reaches 1：4, the proportion of modified agent reaches 16. 7% of the film former and PVC is 18%, the hardness of the film is 2H, impact 50 cm, 60° gloss 90, the adhesion of the film grade one and good al- cohol resistance. And the molecule structure and changes in curing process were analyzed by fourier transform infrared spectroscopy （ FT - IR）.
