Abstract

The invention provides an anti-icing nano-coating for an extra-high voltage line surface in mountain areas. The coating includes the following raw materials by weight: 30-50 parts of fluorosilicone resin, 2-5 parts of carbon nanotubes, 2-5 parts of nano Ni, 6-8 parts of diamond carbon, 5-8 parts of a light absorbing pigment, 4-6 parts of nano TiO2, 8-12 parts of nano SiO2, 0.5-1 part of an emulsifier, 0.5-1 part of a defoaming agent, 0.3-1 part of a leveling agent, 1-2 parts of a silane coupling agent, 1-2 parts of a preservative, and 20-30 parts of a solvent. The anti-icing coating has the advantages of water contact angle of 131-169 DEG, strong hardness and wear resistance, and high absorptivity rate and low emission rate.

Description

technical field [0001] The invention relates to an anti-icing coating for ultra-high voltage transmission lines, in particular to an anti-icing nano coating for the surface of ultra-high voltage lines in mountainous areas and a preparation method thereof. Background technique [0002] While my country's economy continues to grow at a high speed, energy issues have increasingly become a bottleneck for stable and sustainable economic development. Based on the basic national conditions of my country's unbalanced energy distribution and productivity development, the State Grid Corporation plans to build an AC 1000 kV and DC ±800 kV UHV power grid in order to optimize the allocation of power resources in a wider range and realize the efficient use of my country's limited energy resources. use. Due to the long transmission distance of UHV transmission lines, in some mountainous areas with complex terrain, the span of UHV transmission lines, the diameter of conductors and the heigh...
