The epoxy resin polymer is highly adhesive, highly resistant to acid, alkali and heat and high in mechanical performance, and has the electrochromatic performance of triphenylamine, the shear strength of the epoxy resin polymer is about 30MPa, and the maximum service temperature of the epoxy resin polymer is up to 120 DEG C. The electrochromatic epoxy resin polymer and the preparation method thereof are applicable to the field of electrochromism.

Description

technical field [0001] The invention relates to an epoxy resin polymer and a preparation method thereof. Background technique [0002] 1. Epoxy resin adhesive [0003] As an emerging chemical material, epoxy adhesive has good chemical stability, small curing shrinkage, and excellent bonding performance, and its role in various fields is increasing. [0004] Epoxy glue has the following characteristics, (1) a wide range of bonding, which solves the problem of bonding with large performance differences (such as steel and concrete) and large size differences (such as extremely thin and extremely thick), (2) the connecting parts are in the joint Under reasonable conditions, the force on the connection part is uniform. (3) Compared with traditional adhesives, the connection process is light in weight, which is very important for aircraft and aerospace. Of course, there are also shortcomings, such as impact strength, peel strength is not high, and the quality of bonding is affec...
