摘　　要：汽车水性金属闪光底色漆以水性饱和聚酯树脂为基体树脂,以甲醚化氨基树脂为交联剂,以水性闪光铝粉为效应颜料,以改性乙烯-醋酸乙烯共聚物蜡乳液为定向排列剂,在基材润湿剂、消泡剂、流平剂、增稠剂、中和剂、助溶剂、去离子水等配合下精制而成。涂膜于160℃、20 min条件下固化,具有VOC含量低、硬度高、抗冲击、附着力强、闪光效果好、防腐性能优异、绿色环保、施工安全方便等优点。The automotive waterborne metallic flash basecoat was prepared by aqueous saturated polyester resin as matrix resin, methylated amino resin as a crosslinking agent, water-based flash aluminum powder as effect pigment, modified ethylene-vinyl acetate copolymer wax emulsion as directional alignment agent, and it is refined by substrate wetting agent, defoamer, leveling agent, neutralizer, thickener, cosolvent and deionized water. The film is cured at 160 ℃ for 20 minutes, it has some advantages such as low VOC content, high hardness, impact resistant, strong adhesion, good flash, excellent corrosion resistance, environmental protection, construction safety and convenience, etc.
