Problems solved by technology

At present, there are many similar coating reports and products at home and abroad, but domestic patented technologies such as CN1690147A and CN95112601.6 focus on improving the hydrophobicity and mechanical strength of the coating surface; and foreign products have been proved by hanging nets. Better adapt to China's complex climate and environmental conditions, which reduce the use effect and service life of anti-pollution flashover

Abstract

The invention relates to a tracking-proof corrosion-proof room temperature silicon disulfide rubber composite which has the following formula: 30-70 parts of polysiloxane by weight, 5-40 parts of reinforced filler by weight, 10-70 parts of electric corrosion resistance stabilizer by weight, 5-15 parts of auxiliary agent by weight and 10-80 parts of diluent by weight. The tracking-proof corrosion-proof room temperature silicon disulfide rubber composite provided by the invention has favourable tracking-proof corrosion-proof performance, has higher tensile strength, breaking elongation and tearing strength as well as favourable surface hydrophobicity, hydrophobicity transference and hydrophobicity restoration and is a functional composite capable of effectively preventing and curing pollution flashover.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a room temperature vulcanized silicone rubber composition with resistance to electric tracking and corrosion. Background technique [0002] Under humid conditions (light rain, drizzle, fog, condensation, snowmelt, etc.), pollution flashover is prone to occur on the electric porcelain surface of power equipment. When pollution flashover occurs on equipment, the success rate of reclosing is very low, often causing large-scale power outages, and the accompanying strong arcs also cause damage to electrical equipment, prolonging the power outage time, and seriously threatening the safe and stable operation of the power system. According to statistics, in the 11 years from 1976 to 1986, the power loss caused by pollution flashover accidents was as high as 170 million kilowatt-hours, which is astonishing. Serious consequences. [0003] Practice has proved that the most direct way to reduce or...
