Rubber material with self-stress icebreaking and phase-change snow melting functions for asphalt road and preparation method of rubber material

The invention discloses an asphalt road rubber material with self-stress icebreaking and phase-change snow melting functions and a preparation method thereof.The preparation method comprises the steps that stable oil-in-water emulsion is prepared with n-tetradecane as a phase-change core material, then modification is conducted through KH550, crosslinking between graphene and vinyl MQ silicon resin is promoted, and the self-stress icebreaking and phase-change snow melting functions are achieved; carrying out hydrolytic polycondensation on the prepolymer on the surface of the oil-in-water emulsion by using an in-situ emulsion polymerization method to prepare the modified graphene oxide-vinyl MQ silicon resin composite wall material phase change microcapsule; the vinyl MQ silicon resin is subjected to a cross-linking reaction with a cross-linking agent hydrogen-containing silicone oil of rubber through active vinyl groups on the surface of the vinyl MQ silicon resin, so that the reinforcing effect is achieved,
