Abstract

The invention relates to imide organic silica gel and a preparation method thereof. The imide organic silica gel is composed of a reaction product of 1, 4-di(2, 4-aminophenoxy)benzene 14BDAPB, double-terminated aminopropyl polydimethylsiloxane YASI, maleic anhydride, aromatic diamine, aromatic binary anhydride and 3-aminopropyl trialkoxysilane and an organic solvent. Raw material source is convenient, process is simple, operation is convenient, and the imide organic silica gel is good in comprehensive performance, can be applied in bonding of glass, ceramic, composite materials, special-polarity textile prepreg and composite material base materials thereof and has good market application prospect.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to an imide organic silica gel 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 CN106220851A discl...
