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
