▎ 摘　　要

NOVELTY - Graphene-modified unsaturated polyester resin glue comprises 100 pts. wt. component A and 0.8-2 pts. wt. component B. The component A is composed of 100 pts. wt. unsaturated polyester resin, 5-9 pts. w.t tung oil, 0.6-1 pts. wt. sodium diethyldithiocarbamate, 4-10 pts. wt. calcium sulfate whiskers, 0.5-1.5 pts. wt. modified nano glass fiber powder, 0.1-0.3 pts. wt. modified graphene, and 0.5-0.7 pts. wt. cobalt naphthalate. The component B. is methyl ethyl ketone peroxide. USE - The graphene modified unsaturated polyester resin adhesive is useful for painting and glass steel. ADVANTAGE - The graphene modified unsaturated polyester resin adhesive is easy to produce and manufacture, and only needs to mix the component A and the component B evenly, can resist the erosion of chemical media during use, and has the characteristics of good flexibility, no cracking, and aging resistance.
