Abstract

The invention relates to an energy-absorbing super-amphiphobic anti-icing coating, and relates to the technical field of power transmission equipment. The coating is prepared from the following raw materials in parts by weight: 5-15 parts of super-amphiphobic modified black color paste; 1-5 parts of porous filler powder; 40-77 parts of modified acrylic resin; 1-5 parts of a dispersant; 0.5-2 partsof a defoaming agent; 0.5-3 parts of leveling agent; and 15-30 parts of solvent. The coating formed by the energy-absorbing super-amphiphobic anti-icing coating has super-amphiphobic, super-self-cleaning, anti-fouling and anti-icing capabilities so that dust cannot be attached to the surface of the coating of power equipment using the coating and water on the surface of the coating can take awaydust on the surface layer; an obvious delayed icing effect is achieved in ice and snow weather and the icing amount can be greatly reduced; meanwhile, the coating is extremely easy to deice even at anextremely low temperature due to the energy absorption characteristic of the coating so that the electric power facility using the coating has the functions of self-cleaning and icing prevention.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to an energy-absorbing superamphiphobic anti-icing coating and a preparation method thereof. Background technique [0002] With the construction and networking of UHV transmission lines, the safety and stability of transmission lines are becoming more and more important. Icing is very harmful and will have a great impact on the actual power system. It will seriously reduce the power supply capacity of equipment, affect the power demand of users, and even cause dangerous accidents. This is a major safety hazard in real life. The impact of icing on the power system cannot be ignored, and its harm makes the power equipment unable to safely provide power supply services and cannot meet the power supply in production. The problem of preventing icing does not have a good solution all over the world, and this is a difficult problem in the world. Through unremitting e...
