摘要:

在水性环氧树脂及固化剂双组分体系中，采用浅色导电云母粉和钛白粉，优选环保型防锈颜料，运用扫描电镜、激光粒度分析仪、表面电阻率测试仪等分析手段研究了导电云母粉的粒径、用量、搅拌分散速度、钛白粉用量以及防沉剂的种类对涂层抗静电性的影响；研究了树脂/固化剂比例、体系颜料体积浓度及防锈颜料种类对涂层综合性能的影响；制备出了一种兼具良好抗静电性、优异防腐蚀性以及良好装饰性的环保水性抗静电防腐蚀涂料。

Abstract：

Using light color conductive mica, titanium oxides and environmentally friendly　 anticorrosive pigments in the two-component epoxy paint system, a new kind of　 environmentally friendly waterborne paint with good antistatic property,　 excellent anticorrosion performance and good ornamental behavior was prepared.　 The antistatic property and anticorrosive performance of the paint were analyzed　 by use of scanning electron microscopy, laser particle diameter analyzer and　 surface resistivity tester. The results indicated that the particle size and the amount　 of conductive mica, its dispersing speed, the amount of titanium oxides, and the　 type of anti-settlement agent have great influence on the antistatic property of　 the paint. Combined with 30 mass % conductive mica (of volume average diameter as　 16.96μm) under its dispersing speed of 1000 r/min and fumed SiO₂ as　 anti-settlement agent, the surface resistivity of the paint can reach to　 10⁶Ω. The optimal addition of titanium oxides is 2.7 mass%. The　 integrated properties of paint were decided by the ratio of epoxy resin to its　 curing agent, the pigment volume concentration (PVC) and the type of anticorrosive　 pigments. As the PVC range from 30% to 35% and the ratio of epoxy resin to its　 curing agent reach to 4:1, the optimal integrated property of the paint can be　 obtained.

Key words： antistatic;anticorrosive;conductive mica;waterborne epoxy resin;environmentally friendly
