Abstract

The invention relates to DAHTM type silicon-containing epoxy imide matrix resin and a preparing method thereof. The matrix resin is prepared from 4,4'-diamido-4''-hydroxy triphenylmethane (DAHTM), epoxy resin, 3-aminopropyl trialkoxysilane, an imide oligomer and a curing agent. The preparing method includes the following steps that 1, the imide oligomer is prepared; 2, DAHTM and epoxy resin are put into a reaction kettle, stirred and mixed for reaction, then the imide oligomer is added, the mixture continues to be stirred for reaction, then 3-aminopropyl trialkoxysilane is added and stirred for reaction, the curing agent is added and stirred to be mixed uniformly to obtain the matrix resin. The matrix resin can be widely applied to adhesion between metal such as steel, copper and aluminum and a base material such as ceramic, glass and a resin-based composite material and used for preparing glass fiber, aramid fiber and carbon fiber reinforced composite and has good industrial prospects.

Description

technical field [0001] The invention belongs to the field of polymer matrix resin and its preparation, in particular to a DAHTM silicon-containing epoxyimide matrix resin and a preparation method thereof. Background technique [0002] As we all know, epoxy resin has many excellent properties: (1) Good bonding performance: high bonding strength, wide bonding surface, it is compatible with many metals (such as iron, steel, copper, aluminum, metal alloys, etc.) The bonding strength of metal materials (such as glass, ceramics, resin-based composite materials, wood, plastics, etc.) is very high, and some even exceed the strength of the bonded material itself, so it can be used in many stressed structural parts. One of the main components of the mixture; (2) good processing performance: the flexibility of epoxy resin formula, the diversity of processing technology and product performance are the most prominent among polymer materials; (3) good stability performance: ring The curi...
