Phenolic resin （PF） and nano-SiO2 were used to improve the curing property and high humidity resistance of epoxy resin （EP） and methyl nadic anhydride （MNA） resistor paint, respectively. Hydrogen bonds, formed between phenolic resin and nano-SiO2 in alcohol, made nano-SiO2 disperse easily in EP/MNA paint through phenolic resin without being treated by supersonic vibration. When the mass ratio of PF to EP in paint is 3：7, the formed composite paint film can be cured in 2 min at 170 ℃. When the mass ratio of nano-SiO2 to PF in paint is 3：100, the property of high humidity .resistance of the composite paint is the best, meeting the requirement of varying ratio of resistance less than 0.1% after experiment on high humidity resistance. SEM analysis shows the surface of the composite paint film is smooth, glassy, tight and homogeneous, without acicular air holes.
