摘 要:针对汽车发动机 体上涂装的防护涂层经超声波-化学清洗工艺容易被破坏和剥离的
难题,研制了一种高性能水性单组分浸涂漆并研究其应用效果;探讨了浸涂漆的成膜物、润湿剂、催
干剂和附着力促进剂对漆膜的附着力、耐水性、耐盐雾性和耐超声波-化学清洗性能的影响。结果表
明:选择水性丙烯酸改性环氧酯树脂 TH-8180和改性水性环氧分散体 H-502-42W 按照质量比 6∶4作
为成膜物,选择润湿剂 BW-104E 和 HOS 2413按照质量比 2∶3进行复配,同时,添加 5% 无钴环保催干
剂 OXY-Coat1101和 1. 5% 附着力促进剂 MOAP 1880,制备的水性单组分浸涂漆对发动机 体的润湿
性良好,漆膜的干燥速度快,耐水性、耐盐雾性和耐超声波-化学清洗性优异。

Abstract:To solve the problem that the protective coating on the automobile engine
cylinder block was easy to be destroyed and peeled off by the ultrasonic-chemical cleaning
process,a high-performance waterborne one-component dip-coating was developed and its
application effect was studied in this paper. The effects of film former,wetting agent,drier and
adhesion promoter on the adhesion,water resistance,salt spray resistance and ultrasonic-
chemical cleaning resistance of the paint film were discussed. The results showed that the
waterborne acrylic modified epoxy ester resin TH-8180 and the modified waterborne epoxy
dispersion H-502-42W were selected as the film-forming material according to the mass ratio of 6∶
a
4,nd the wetting agent BW-104E and HOS 2413 were selected according to the mass ratio of
2∶3. At the same time,5% cobalt-free environmental protection drier OXY-Coat1101 and
