Document Type and Number:
WIPO Patent Application WO/2023/082310
Kind Code:
A1
Abstract:
A graphene modified conjugated diene resin and a preparation method therefor and an application thereof. The graphene modified conjugated diene resin comprises a conjugated diene resin and graphene, the graphene is distributed on the surface of or inside the conjugated diene resin, and the conjugated diene resin comprises at least one of a dicyclopentadiene resin and a tricyclopentadiene resin. The graphene modified conjugated diene resin has excellent corrosion resistance, the mechanical strength retention rate of the graphene modified conjugated diene resin is 85% or above by means of a severe level-5 corrosion performance test, and the mechanical strength of the graphene modified conjugated diene resin meets the use requirements of materials for automobiles, rail transit, infrastructure construction and ocean engineering. Moreover, the graphene modified conjugated diene resin is low in viscosity, has surface air-drying property, and is suitable for large-scale prepreg production.
