Adhesive for direct-current supporting column insulator

Abstract

Provided is an adhesive for a direct-current supporting column insulator. The adhesive is prepared from, by mass, 60-90 parts of solvent dimethyl carbonate, 15-30 parts of cosolvent glycol derivatives, 5-10 parts of nonionic surfactants, 2-5 parts of abrasive nanometal oxide, 1-5 parts of diffusant dichloromethane, 0.5-2 parts of detergent assistant N-alkyl pyrrolidone, 0.2-1 part of stabilizer coconut oil diethanolamide, and 1-3 parts of polymethylsiloxane. Detergent can effectively clear away stains on the surface of an insulator antifouling flashover coating under the environment of high saline-alkali and high industrial pollution, excellent hydrophobicity and migration of the hydrophobicity of the surface of an insulator are recovered, and therefore the capacity of effectively ensuring power equipment to operate safely is achieved.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive for pasting ceramic mandrels and rubber skirts on insulators. Background technique [0002] Existing insulators for high-voltage equipment are mainly divided into two categories: porcelain sleeves made of porcelain materials and silicone rubber hollow composite insulators. There are many structural forms of porcelain bushings, such as straight shape, conical shape and waist drum, etc., but the weight of porcelain bushings is heavy, and it is easy to damage other equipment after explosion. It has low pollution resistance and complicated firing process; the hollow composite insulator itself is light in weight 1 / 4~1 / 10 of the porcelain sleeve, no hidden danger of explosion, good water repellency, significantly improved stain resistance compared with the porcelain sleeve, and the energy consumption of the molding process is far lower than that of the porcelain sleeve. There are ...

Problems solved by technology

The disadvantage of these methods is that the single umbrella body is cemented into a whole, and cracks and other phenomena are prone to occur at the bonding place. Secondly, the insulation, electric corrosion and aging resistance of liquid silicone rubber are poor.

[0003] In the prior art, there is little research on the special adhesive for insulator ceramic core and rubber, and it is necessary to improve it
