Abstract

The invention discloses a preparation method of a micropore organic silicone adhesive which is prepared from 30-50 percent of organic silicone adhesive, 1-10 percent of crosslinking agent, 1-10 percent of catalyst, 1-20 percent of coupling agent, 0.5-5 percent of inhibiting agent, 10-50 percent of tackifying resin and 1-30 percent of foaming agent through reaction. The invention aims at reconstructing the common organic silicone adhesive into a micropore organic silicone adhesive with a micropore structure, so that the organic silicone adhesive has exhaust property and absorption property, and micropores are hollow and have functions of absorbing molecules. The micropores of the organic silicone adhesive can be regulated, and can be arranged randomly, and the structure of the micropores and the size of the viscosity are determined according to the final requirement.

Description

[0001] technical field [0002] The invention relates to an organic silica gel adhesive, in particular to a preparation method of an organic silica gel adhesive with micropores, and belongs to the technical field of adhesive materials. Background technique [0003] The adhesive of the silicone adhesive is a linear high molecular mass prepared by one or several linear, cyclic or branched siloxanes under the action of a catalyst through reactions such as equilibrium, addition or condensation. Or cross-linked siloxane composition. There are mainly two types of silicone adhesives: rubber type and resin type. Silicone adhesives have the characteristics of high temperature resistance, stable adhesion and good durability, and are widely used in various fields such as aviation, navigation, spacecraft, rockets and missiles, atomic energy, and electronic and electrical industries. With the gradual expansion of the application range of silicone adhesive tapes, all walks of life have ...
