Abstract

In order to overcome the limitation that the prior anti-pollution flashover coating only can be operated after power failure, the application of the invention provides a preparation method of anti-pollution flashover coating suitable for coating live electrical equipment and the anti-pollution flashover coating. The anti-pollution flashover coating comprises the following raw materials: room temperature vulcanizing silicone rubber, diluent trichloro ethane, reinforcing agent gas phase method SiO2, fire retardant mixture of Al(OH)3 and Mg(OH)2, arc resistant agent decabromodiphenyl oxide, addictive hydroxy silicone oil, catalyst chelated titanate and crosslinker methyl triethoxysilane, and is prepared by mixing the raw materials to react in vacuum. Compared with the prior art, in the technical scheme of the invention, the dielectric strength and the anti-tracking erosion in the electrical properties are obviously superior to the prior art, the anti-pollution flashover coating has technical characteristics of non-combustion and no flashover under a spray pattern, thereby truly ensuring that the anti-pollution flashover coating can be implemented with safe spray painting work under the electriferous state of the electrical equipment.

Description

technical field [0001] The patent application of the present invention relates to an anti-pollution flashover coating mainly for electric equipment and a preparation method thereof. Background technique [0002] Pollution flashover accidents have become one of the most serious accidents in the power system due to their wide range of influence, long power outages, and huge losses. Therefore, how to avoid pollution flashover accidents and ensure the safe and stable operation of the power grid is an important issue for the development of the electric power industry. technical issues. Research and practice have shown that coating anti-fouling flashover coatings on the surface of insulators is the most economical and effective anti-fouling flashover measure. However, the existing antifouling flashover coatings can only be sprayed or brushed after a power failure. This method of coating operation brings great problems. Dry and sunny weather with suitable temperature is very diff...
