Abstract

The invention relates to a TADE-type silicon-containing adhesive and a preparation method thereof. The TADE-type silicon-containing adhesive consists of a reaction product of 3,3',4,4'-tetraamino diphenyl ether (TADE), maleic anhydride, aromatic diamine, aromatic dianhydride and 3-aminopropyl trialkoxy silane, and an organic solvent. Sources of the raw materials are convenient, the process is simple, operation is convenient, and comprehensive performance of the product is good. The TADE-type silicon-containing adhesive can be applied to binding base materials of glass, ceramic, composite materials, special polar textile prepreg and composite materials of the glass, the ceramic, the composite material and the special polar textile prepreg, and a good market application prospect is achieved.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a TADE type silica gel-containing adhesive and a preparation method thereof. Background technique [0002] Adhesive systems are widely used in various fields of the national economy: whether it is high-tech or general-purpose technology, whether it is national defense or civilian industry, or even people's daily life. [0003] There have been many research reports on adhesive systems or silicone resin systems, and there are also many invention patents: [0004] Chinese invention patent CN102786902A discloses a silicone organic fluorine epoxy adhesive and a preparation method thereof. [0005] Yan Rui, Yu Xinhai et al [Research on Preparation and Properties of New Epoxy Adhesives, Insulating Materials, 2012, 45(2): 12-14,18] disclosed a new type of epoxy resin adhesive and its preparation method, and its performance has been systematically studied. [0006] Chinese invention patent CN1...
