Title:
GRAPHENE MODIFIED ASPHALT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/016442
Kind Code:
A1
Abstract:
The present invention relates to the technical field of asphalt preparation, and in particular relates to graphene modified asphalt and a preparation method therefor. The graphene modified asphalt provided in the present invention is prepared from the following raw materials in parts by weight: 100-140 parts of asphalt, and 1-20 parts of a modifier, wherein the modifier is modified graphene, and is prepared from the following raw materials: graphene, a styrene-butadiene-styrene block copolymer, polyurethane, rubber, a compatilizer, a coupling agent, sulfur and an accelerant. The graphene modified asphalt provided in the present invention has relatively strong aging resistance, fatigue resistance and hydrophobicity.
