AI Technical Summary

Problems solved by technology

The currently used RTV silicon antifouling flashover coating formulations are generally added with reinforcing fillers or special additives to improve the mechanical properties and adhesion of the coating. The existing scavengers cannot remove the failed coating in a short time at room temperature, and Dichloromethane, chloroform and other components in the scavenger are highly toxic. For example, the European Union has explicitly banned the use of dichloromethane cleaning agents
At present, manual tearing or bamboo scraping is still used to remove the invalid paint in field operations, which is time-consuming and laborious, and the removal effect is poor, and it may damage the body of the electric porcelain insulator

Abstract

The invention discloses a remover of electric porcelain insulator surface failure paint. The remover is obtained by mixing of 5-20 weight parts of a fluoride, 1-5 weight parts of an organic quaternary ammonium alkali, 20-50 weight parts of a solvent, 1-10 weight parts of an activator, 5-30 weight parts of a penetrating agent and 1-5 weight parts of a thickening agent. The remover can be prepared by simple processes, is convenient for use, has a fast reaction rate and high peeling efficiency, does not damage an insulator substrate and can be widely used for popularization.

Description

technical field [0001] The invention relates to a stripping agent for ineffective paint on the surface of electric porcelain insulators. Background technique [0002] Electric porcelain insulators are important accessories used in power transmission and transformation lines and equipment. When their surfaces are covered by pollution and affected by rain and fog, electric pollution flashover accidents are prone to occur. Coating a layer of room temperature vulcanized silicone rubber coating on the surface of electric porcelain insulators is one of the effective measures to prevent pollution flashover. [0003] Room temperature vulcanized silicone rubber anti-pollution flashover coating is a kind of electrical functional material for power system. It is a product specially designed for power grids and various power generation, transmission and electricity customers to permanently and completely eliminate the hidden danger of equipment pollution flashover. RTV silicone rubber ...
