| Abstract: | The effects of coupling agent,pigment and filler used in fluorocarbon resin paint on the performance of the coatings made of the fluorocarbon resin paint were investigated based on energy dispersive spectrometric analysis,scanning electron microscopic analysis, contact angle tests and scratching tests.Results show that the surface of the coatings has a higher fluorine content than the underlayer, and contains nano-sized protrusions.The coatings made of the paint with coupling agent content of above 3.0%possessed stronger hydrophobicity and adhesion to substrate,but their corrosion resistance remained almost unchanged.Increasing content of rutile TiO2 in the paint resulted in reduced hydrophobicity as well as increased adhesion and corrosion resistance of the coatings. Moreover,gas-phase SiO2 had little effect on the hydrophobicity of the coatings.With increasing content of SiO2,the adhesion of the coatings was reduced,and the corrosion resistance of the coatings initially rose but later declined therewith.The fluorocarbon coatings made of the paint consisting of 5.5%- 8.5% coupling agent,2.0% 6.0%TiO2 and 2.5 6.1%SiO2 possessed better performance. |
