Title:
GRAPHENE MATERIAL FOR ASPHALT MODIFICATION AS WELL AS PREPARATION METHOD AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2020/034822
Kind Code:
A1
Abstract:
Disclosed is a graphene material for asphalt modification as well as a preparation method and application. The graphene material for the asphalt modification comprises partially oxidized graphene powder and a surface grafting modifier. The partially oxidized graphene powder is connected to an inorganic affinity group in the surface grafting modifier by means of an oxygen-containing functional group on the partially oxidized graphene powder. The oxygen content in the partially oxidized graphene powder is 0.05%-15%. Also disclosed is the application of the graphene material for the asphalt modification or the preparation method of the graphene material in matrix asphalt and modified asphalt.
