Abstract

The invention provides an insulating coating special for high-voltage lines. The insulating coating is prepared from the following raw materials in parts by weight: 55-60 parts of polytetrafluoroethylene emulsion, 20-25 parts of silica powder, 10-13 parts of titanium dioxide, 0.5-1 part of polyethylene wax, 0.6-0.8 part of defoamer, 15-20 parts of glycerol, 16-18 parts of n-butyl acetate and 80-90 parts of water. The insulating coating has excellent non-corrosibility and high and low temperature resistance in addition to excellent insulation property, and the coating has excellent wear resistance.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a special insulating coating for high-voltage electric wires. Background technique [0002] Special coatings for high-voltage wires play an important role in the field of coatings, effectively protecting the safety of high-voltage lines, prolonging the life of lines, and providing security for people's lives. At present, the common coatings for high-voltage wires have good insulation performance, but their cold resistance, heat resistance and corrosion resistance are not good, and the weather resistance needs to be further improved. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the field of coatings. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and propose a special insulating coating for high-voltage electric wires. The coating of...
