▎ 摘　　要

NOVELTY - A graphene/epoxy resin composite polymer material comprises first component and second component. The first component comprises graphene and epoxy resin (128). The second component comprises curing agent and catalyst. The curing agent is pentaerythritol tetramercaptopropionate epoxy resin prepolymer (PPTM). The graphene has amount of 5-15% of the mass of epoxy resin (128). USE - Graphene/epoxy resin composite polymer material. ADVANTAGE - The composite polymer material has fast curing speed, good compatibility of raw materials, good mechanical property, low cost, simple preparation method, small environment pollution, and tensile strength of 6.75-28.29 N/mm. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the polymer material comprising mixing raw materials, and curing for 99-261 seconds.
