Title:
PREPARATION OF GRAPHENE/NATURAL RUBBER WITH SIMULTANEOUSLY IMPROVED MECHANICAL PROPERTY, HEAT CONDUCTION AND WEAR RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2023/241196
Kind Code:
A1
Abstract:
A method for preparing graphene/natural rubber with simultaneously improved mechanical property, heat conduction and wear resistance, comprising: forming graphene oxide loaded with nano silicon dioxide by means of electrostatic interaction between silicon dioxide and graphene oxide; adding graphene oxide loaded with nano silicon dioxide into natural latex; preparing a graphene master batch by using an aqueous phase synergistic coagulation process; and obtaining graphene/natural rubber by means of a mechanical blending method and a vulcanization process. The electrostatic interaction between silicon dioxide and graphene oxide is a dynamic acting force which not only reinforces the crosslinked network structure of the graphene/natural rubber composite material and significantly increases the crosslinking density, but also enables the graphene filler to entangle a large amount of rubber molecular chains and enhances the interface interaction between the graphene and the rubber matrix in the dynamic movement process of the rubber, thereby improving the mechanical property, the heat conduction and the wear resistance simultaneously.
