Abstract
The present invention discloses a rubber material for asphalt roads having both self-stress ice breaking and phase-change snow melting functions and a preparation method thereof. A stable oil-in-water emulsion is prepared with n-tetradecane as a phase-change core material, then KH550 modification is performed to promote cross-linking of graphene and vinyl MQ silicone resin, and then a prepolymer is subject to hydrolytic polycondensation on a surface of the oil-in-water emulsion using an in-situ emulsion polymerization method to prepare modified graphene oxide-vinyl MQ silicone resin composite wall material phase-change microcapsules; vinyl MQ silicone resin undergoes a cross-linking reaction with hydrogen-containing silicone oil, a cross-linking agent of rubber, through active vinyl groups borne on the surface, thereby achieving a strengthening effect, effectively improving viscoelasticity and stress-strain behaviors of the silicone rubber, and preparing the rubber material for asphalt roads having both good elasticity and phase-change energy storage function.
