[0002] Epoxy resin AB glue is a two-component adhesive, mainly composed of epoxy resin component A and curing agent component B. It contains two or more epoxy groups in a molecular structure, and can form a three-dimensional cross-linked cured compound under appropriate chemical reagents and conditions.

[0003] However, the existing epoxy resin AB glue may have a relatively insufficient toughness during actual use, which is specifically manifested in that the epoxy resin AB glue is relatively brittle after curing and is more likely to crack. Therefore, an epoxy resin AB glue and a preparation method thereof are invented. Summary of the invention

[0004] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0005] An epoxy resin AB glue comprises a component A and a component B, wherein the raw materials of the component A comprise, by weight: 10-20 parts of bisphenol A epoxy resin, 8-12 parts of bisphenol F epoxy resin, 4-12 parts of hydantoin epoxy resin, 6-10 parts of aliphatic epoxy resin, 2-4 parts of toughening agent, 1-5 parts of impact resistance agent, 2-6 parts of thickening agent, 2-4 parts of dispersant, 1-5 parts of stabilizer, 2-3 parts of surfactant, 1-5 parts of adhesive, 2-4 parts of polyetheretherketone, 2-4 parts of silicone rubber, 2-4 parts of polyurethane resin, and 2-4 parts of waterborne epoxy resin;

[0010] As a preferred embodiment of the epoxy resin AB glue described in the present invention, the dispersant is a mixture of one or more of polyolefin acid emulsion, polyvinyl alcohol and polyurethane.

[0011] As a preferred embodiment of the epoxy resin AB glue described in the present invention, the stabilizer is a mixture of one or more of phosphoric acid, p-toluenesulfonic acid, benzoyl chloride and pyrophosphoric acid.

[0012] As a preferred embodiment of the epoxy resin AB glue described in the present invention, the surfactant is a mixture of a surfactant, a solvent and an organic acid, the solvent is a mixture of water, ethanol, methanol and benzene, and the organic acid is a mixture of one or more of citric acid and acetic acid.

[0018] Step 3: Mix component A and component B to obtain epoxy resin AB glue.

[0019] Compared with existing technologies:

[0020] By adding toughening agent and impact resister to component A, the toughness of epoxy resin AB glue can be improved while the impact resistance can be improved, thereby avoiding the cracking of epoxy resin AB glue to a certain extent and improving the stability of use; in addition, by adding polyetheretherketone, silicone rubber, polyurethane resin and water-based epoxy resin, the toughness and temperature resistance of epoxy resin AB glue can be improved while the corrosion resistance of epoxy resin AB glue can be improved, thereby increasing the use environment of epoxy resin AB glue.
