▎ 摘　　要

NOVELTY - An epoxy structural adhesive comprises components (A) and (B) in a mass ratio of 3:1. The component (A) includes 40-50 self-made graphene-modified epoxy resin, 25-30 pts. wt. bisphenol A epoxy resin, 15-20 pts. wt. bisphenol F epoxy resin, 5-10 pts. wt. diluent, 3-5 pts. wt. silane coupling agent (A), 1-2 pts. wt. modified graphene, 1-2 pts. wt. thixotropic agent and 20-30 pts. wt. filler. The component (B) includes 20-25 pts. wt. cardanol modified amine, 10-15 pts. wt. polyamide, 1-2 pts. wt. accelerator, 0.5-1 pt. wt. toughening agent, 16-20 pts. wt. modified fatty amine and 1-2 pts. wt. silane coupling agent (B). USE - The epoxy structural adhesive is useful for prefabricated segment assembly.
