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.
