▎ 摘　　要

NOVELTY - Graphene modified conjugated diene resin comprises conjugated diene resin and graphene, the graphene is distributed on the surface or interior of the conjugated diene resin; and the conjugated diene resin includes dicyclopentadiene resin and/or tricyclopentadienyl resin. USE - The graphene modified conjugated diene resin is useful in automobile, rail transportation, infrastructure construction, and marine engineering (claimed). ADVANTAGE - The graphene modified conjugated diene resin has excellent corrosion resistance, and has passed a severe grade 5 corrosion performance test, has low viscosity and surface air-drying properties, and is suitable for large-scale production of prepreg. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene modified conjugated diene resin comprising heating and mixing all the raw materials to obtain the graphene modified conjugated diene resin.
