Problems solved by technology

[0007] Although the above-mentioned patents all involve high-temperature-resistant epoxy resin adhesives, and also propose some improvements about epoxy resin AB adhesives, it can be seen through careful analysis that these patents do not propose how to improve epoxy resin AB adhesives in high-temperature environments. Under the thermal stability problem, there are still problems such as the decrease of the strength of the epoxy resin AB glue in the high temperature environment, prone to aging and brittleness, so it still needs to be further improved

Abstract

The invention discloses an epoxy resin AB glue used in high-temperature environment and manufacturing and use methods thereof. The epoxy resin AB glue used in high-temperature environment comprises components A and B, wherein a main body of the component A is bisphenol epoxy resin, and hydantoin epoxy resin is added to the component A; and a main body of the component B is low molecular polyamide, and 4,4'-diamino diphenyl sulfone is added to the component B. The components A and B are mixed and cured when in use, and thermal stability and aging resistant performance of the epoxy resin AB glue are improved by a joint action of hydantoin epoxy resin and 4,4'-diamino diphenyl sulfone.

Description

technical field [0001] The invention relates to an epoxy resin glue and its production and use method, especially a high-strength epoxy resin AB glue used in an environment with a temperature above 180°C and its production and use method. This product is mainly used for metal It can also be used for the bonding of high temperature resistant parts such as metal, ceramic and metal, ceramic and ceramic, and can also be used for the cold welding process of different metals and other plastics, especially for the bonding of high temperature resistant parts such as brushless motors. Background technique [0002] Epoxy resin adhesive (epoxy resin adhesive) generally refers to the adhesive made with epoxy resin as the main body, and epoxy resin adhesive is divided into soft glue and hard glue. Most epoxy resin glues are hard glues with high hardness but high brittleness. The epoxy resin AB glue of the present invention is a kind of epoxy resin glue, is a kind of two-component high-t...
