Abstract

The invention relates to a 1,3-bis(2,4-diamidophenoxy)benzene high-temperature-resistant epoxy adhesive and a preparation method thereof. The 1,3-bis(2,4-diamidophenoxy)benzene high-temperature-resistant epoxy adhesive is composed of a component A and a component B in a mass ratio of 1:(1-2), wherein the component A is a copolymer prepared by reacting 1,3-bis(2,4-diamido phenoxy)benzene and epoxy resin; and the component B is a homogeneous-phase transparent solution with the solid content of 15-30%, which is prepared by reacting 1,3-bis(2,4-diamidophenoxy)benzene and aromatic dibasic acid anhydride in a strong-polarity non-proton organic solvent and toluene. The preparation method comprises the following step: evenly mixing the component A and the component B in a mass ratio of 1:(1-2) at room temperature. The preparation technique is simple; and the adhesive has excellent comprehensive properties, can be widely used for bonding steel, copper, aluminum or any other metal with ceramic, glass, resin-base composite material or any other substrate, and has favorable industrialization prospects.

Description

technical field

[0001] The invention belongs to the field of epoxy resin adhesives and preparation thereof, in particular to a 1,3-bis(2,4-diaminophenoxy)benzene type high temperature resistant epoxy adhesive 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...
