Embodiment Construction
[0013] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0014] The formula of the toughened epoxy resin is: six raw materials such as bisphenol A epoxy, polyethylene glycol, benzyl alcohol, epoxy silane coupling agent, sodium hydroxide and benzene. Bisphenol A epoxy, polyethylene glycol, benzyl alcohol and epoxy silane coupling agent form a toughened epoxy resin reaction system A, and the epoxy silane coupling agent is bis(dioctyl pyrophosphate acyloxy) Ethylene titanate-acrylamide chelate increases the adhesive density, polyethylene glycol PEG is used to enhance the toughness of the sys...
