Abstract

The invention discloses an anti-icing coating for an ultra-high voltage power transmission line. The coating includes the following raw materials by weight: 50-60 parts of silicon fluorine resin, 6-10 parts of diamond like carbon, 2-3 parts of carbon nanotube, 5-8 parts of nano TiO2, 8-12 parts of nano SiO2, 0.3-1 part of a dispersant, 0.5-1 part of an antifoaming agent, 0.3-1 part of a leveling agent, 1-3 parts of an anticorrosive and bactericidal agent, and 20-30 parts of a solvent. The anti-icing coating for ultra-high voltage power transmission line has contact angle with water reaching 135-165 DEG C, also has good heating effect, the average temperature rise of 9.5-16 DEG C, very high hardness, excellent adhesion performance, acid and alkali resistance and wear resistance.

Description

technical field [0001] The invention relates to an anti-icing coating, in particular to an anti-icing coating for an ultra-high voltage transmission line and a preparation method thereof. Background technique [0002] my country frequently suffers from ice disasters, and the annual ice disasters bring huge direct and indirect economic losses to the power system. Split conductors have appeared one after another. In some areas with complex terrain and long-spanning line sections, the diameter and height of the conductors of EHV transmission lines have also been greatly improved. The hazards caused by transmission lines to ensure that the EHV transmission system has sufficient safety and reliability have important economic and social values. Anti-icing materials in the prior art can be divided into electrothermal materials, photothermal materials and super-hydrophobic materials according to different anti-icing principles. Ice materials have good electrothermal properties under...
