Outline
In order to guide the selection of fluorocarbon resin film forming material cured at room temperature in the development of anti-pollution flashover coating, the structure and properties of fluorocarbon resin film forming materials were characterized by FT-IR, AFM, UV ageing, thermogravimetric analysis, contact angle test, volume resistivity and high-voltage capacitor bridge. The results show that the optimal mass fraction of curing agent for FEVE-based type I and type II fluorocarbon resins are 19% and 24%, respectively. Under the optimal curing agent content, the contact angle of FEVE-based type I and type II fluorocarbon resins are 91° and 104°, respectively. After UV ageing for 800 h, the appearance color, hydrophobicity, hardness, adhesion, thermal decomposition temperature, and molecular structure do not change. After 30 min of ultrasonic fog wetting, the AC wet lightning voltage of fluorocarbon resin is about 25 kV, indicating that the FEVE-based fluorocarbon resin has excellent electrical insulation properties and ageing resistance, and is a good base material for the development of antifouling flashover coatings.
