Abstract

The invention provides anti-icing nano-paint for surfaces of ultra-high-voltage lines in mountainous areas. The anti-icing nano-paint comprises raw materials in parts by weight as follows: 35-55 parts of fluoro-siloxane resin, 6-10 parts of a light-absorbing pigment, 2-4 parts of nano-TiO2, 6-12 parts of nano-SiO2, 0.3-1 part of a dispersing agent, 0.5-1 part of a defoaming agent, 0.3-1 part of a levelling agent, 1-3 parts of a preservative bactericide and 20-40 parts of a solvent. The prepared anti-icing nano-paint for the surfaces of the ultra-high-voltage lines in the mountainous areas has a contact angle ranging from 129 degrees to 168 degrees with water, the higher light absorptivity ranging from 0.92 to 0.96 and the lower emissivity ranging from 0.16 to 0.28 and is resistant to acid and alkali and high in adhesion.

Description

technical field [0001] The invention relates to an anti-icing coating on the surface of an ultra-high voltage transmission line, in particular to an anti-icing nano coating on the surface of an ultra-high voltage line in a mountainous area and a preparation method thereof. Background technique [0002] my country's ultra-high voltage transmission lines are generally relatively long distances, and many ultra-high voltage transmission lines pass through steep mountainous areas with cold climate, high altitude, and inaccessible people. The terrain in mountainous areas is complex and the climate is changeable. The ultra-high voltage lines in mountainous areas are more likely to suffer from icing disasters. , and due to the special and complex geographical conditions in mountainous areas, it is difficult to use equipment to remove the ice after the icing disaster occurs on the ultra-high voltage lines in mountainous areas. The anti-icing material on the surface of the line can redu...
