环氧树脂具有优良的电绝缘性能、高强度、耐化学腐蚀和对金属、非金属材料的优异粘结力,以及收缩性小等特点。广泛用于航空、电子、仪表、化工、建筑、机械、汽车、造船、水电及军事等部门。随着经济建设的发展,对环氧树脂的性能要求也越来越高。目前仍以改性或改变固化组份,以配制单组份或低温固化使用方便而又具有高性能品种,并扩大应用为主要研究内容,如:苏联合成了一系列新型环氧树脂液态固化剂,如磷—(β—氨基乙氧基)苯胺,2—氨基—5—(β—氨基乙氧基)吡啶…等等,结构式为:
Epoxy resin has excellent electrical insulation properties, high strength, chemical resistance and excellent adhesion to metals and non-metallic materials, as well as small shrinkage. Widely used in aviation, electronics, instruments, chemicals, construction, machinery, automotive, shipbuilding, utilities and military departments. With the development of economic construction, the performance requirements of epoxy resin are also getting higher and higher. At present, we still modify or change the curing components to prepare single-component or low-temperature curing easy to use and high-performance varieties, and expand the application as the main research content, such as: the Soviet Union synthesized a series of new epoxy resin liquid curing agent , Such as phosphorus- (β-aminoethoxy) aniline, 2-amino-5- (β-aminoethoxy) pyridine ... and so on, the formula is:
