▎ 摘　　要

NOVELTY - A photothermal hydrophobic anti-icing anti-shedding coating material comprises 15-50 pts. wt. modified acrylic resin, 1-15 pts. wt. hydrophobically modified inorganic nanoparticles, 0.5-15 pts. wt. hydrophobically modified photothermal conversion nanoparticles, 0.3-6 pts. wt. wetting dispersant, 0.3-5 pts. wt. defoaming agent, 0.5-5 pts. wt. leveling agent, and 10-70 pts. wt. solvent. When using, the coating material is coated on a surface of metal base material, the modified acrylic resin, nanoparticles and the metal base material have hydrogen bonding between one or more of super-molecule, coordination or polarity interactions, so as to improve the anti-shedding performance of the coating material. The nanoparticles are hydrophobically modified inorganic nanoparticles and/or the hydrophobically modified photothermal conversion nanoparticles. USE - Photothermal hydrophobic anti-icing anti-shedding coating material for power transmission line and equipment (claimed). ADVANTAGE - The coating material components and the surface of the metal wire or the metal plate have excellent adhesion performance. The anti-shedding performance of the hydrophobic coating material is improved. When the wire expands and contracts, the resin surface is not prone to cracks, and is not easy to fall off the surface of the wire. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1.the preparation method of coating material, which involves (1) dispersing modified acrylic resin in solvent, adding dispersant, and stirring uniformly to obtain solution (A), (2) Dispersing the modified hydrophobic nanoparticles and the modified hydrophobic photothermal conversion nanoparticles in solvent, adding dispersant, and dispersing at high speed for 20-60 minutes to mix uniformly to obtain dispersion (B), and (3) mixing the dispersion (B) with the solution (A), adding defoaming agent and leveling agent, and stirring at high speed to obtain a final product; and 2.application of the coating material as photothermal hydrophobic anti-icing anti-shedding coating material for power transmission lines and equipment.
