Abstract

The invention relates to a single-component room temperature vulcanized silicon rubber for sticking an insulator, which belongs to the technical field of an adhesive for sticking the insulator and mainly solves the problems of the existing adhesive of being poor in leveling property, low in adhesive strength and slow in curing. Components of the single-component room temperature vulcanized silicon rubber for sticking the insulator comprise 100 parts of monohydroxyl-terminated polydimethylsiloxane polymer, 10-15 parts of gas phase white carbon black, 18-25 parts of silicone oil plasticizer, 6-10 parts of cross-inking agent, 1.7-4 parts of coupling agent, 10-15 parts of mineral oil and 0.1-1 part of catalyst. The single-component room temperature vulcanized silicon rubber has good leveling property, is high in adhesive strength, fast in deep curing, convenient to construct and operate and widely applicable to sticking and assembling of the insulator.

Description

technical field [0001] The invention relates to a single-component room temperature vulcanized silicone rubber adhesive, in particular to a room temperature vulcanized silicone rubber adhesive for bonding insulators with single component self-leveling, high adhesiveness and fast deep curing. Background technique [0002] Insulators are generally composed of three parts: mandrel, sheath (umbrella plate) and metal joints. During the assembly process, the three parts must be glued into a solid whole by using bonding technology. At the same time, due to the particularity of the use environment, safety and assembly process of the insulator, there are also many requirements for the adhesive technology: First, the insulator requires the adhesive to have low viscosity and good fluidity before it is cured during the assembly process, that is, it has excellent fluidity. Flatness; and long operating time, the most important thing is that it has good adhesion and high strength to insula...
