High-voltage power transmission line ice-covering-proof paint and preparation method thereof

The invention discloses high-voltage power transmission line ice-covering-proof paint and a preparation method thereof. The preparation method comprises the following steps: using toluene diisocynate, tridecafluoro-octanol, butyl acetate, organosilicon modified epoxy resin, epoxy resin curing agent, organic solvent, nanographite and carbon nanotubes as raw materials to react and ensure that long-carbon-chain fluoro-alcohol is grafted in the molecular chain of epoxy resin, and adding nanographite and carbon nanotubes in the modified epoxy resin to prepare the paint with good hydrophobicity and thermal conductivity. The paint is mainly used in the coating of the high-voltage power transmission line and the coatings of equipment such as the insulator and the transformer case; and the paint has high coating adhesion, is ice-covering-proof and environmental friendly, has the advantages of corrosion resistance, ultraviolet resistance and aging resistance, and no pollution. Compared with the traditional acrylic paint, the paint has the advantages of simple preparation technology and excellent room temperature curing performance and low temperature curing performance, and is convenient to construct and operate.
