▎ 摘　　要

NOVELTY - Vinyl resin composite material comprises 120-150 pts. wt. epoxy vinyl resin, 1-2 pts. wt. initiator, 1-2 pts. wt. adhesive, 0.5-1.5 pts. wt. graphene, 30-40 pts. wt. diphthalonitrile resin and 30-40 pts. wt. dimethyl sulfoxide. USE - Vinyl resin composite material ADVANTAGE - Vinyl resin composite material has better extensibility, extended longer, and has obviously increased strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of vinyl resin composite material, which involves: i. dissolving diphthalonitrile resin in dimethyl sulfoxide to make a uniform solution, then adding epoxy vinyl resin and initiator to mix evenly to form a blended resin solution; ii. under normal temperature conditions, adding graphene is evenly into the adhesive, stirring evenly, and placing in a mixing device for full mixing to obtain the graphene adhesive; iii. mixing blended resin solution and graphene adhesive fully and spraying onto the cotton stalk skin fiber felt, and then heating and curing to form.
