NOVELTY - Conductive double-hydrophobic coating comprises 10-20 wt.% silicate, 40-80 wt.% aqueous resin, 10-30 wt.% aqueous antifouling additives, 5-20 wt.% nano conductive materials, 3-10 wt.% nano wear-resistant filler, 0.5 wt.% drying agent and 0.5-10 wt.% common additives. USE - The hydrophobic coating is useful cleaning-free oil smoke purifier including electrostatic oil smoke purifier (claimed). ADVANTAGE - The hydrophobic coating: ensures the surface of the oil fume purifier does not stick to oil and does not accumulate fouling, thus the oil fume purifier does not need to be cleaned; and has functions of hydrophobic, oleophobic, easy to clean and wear-resistant, convenient construction, and economic cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing mixing silicate and water-based resin, adding hydroxy-modified acrylic resin, nano conductive materials, nano wear-resistant filler, common additives and drying agent into the mixture under stirring conditions, stirring evenly and dispersing at high speed for 30 minutes to obtain final product; and (2) cleaning-free oil smoke purifier, where the fin of the cleaning-free oil smoke purifier is sprayed with the conductive double-hydrophobic paint.
