Preparation method for high-strength and anti-aging thermoplastic elastomer

The invention relates to a preparation method for a high-strength and anti-aging thermoplastic elastomer, which belongs to the technical field of thermoplastic elastomer preparation. The invention introduces graphene into thermoplastic elastomer to increase the mechanical properties and anti-aging property of substrate, each carbon atom of graphene is provided with an individual Pi electron, the Pi electrons can freely move on the surface of graphene, moreover, each carbon atom is combined with three adjacent carbon atoms, producing Sigma bonds, the bond energy of the Sigma bonds is extremelyhigh, and thereby the high-temperature resistance and low-temperature resistance of the substrate are increased. Nano-silica prepared by the invention is integrated into the thermoplastic elastomer material, the nano-silica can get deep into macromolecular compound to tightly combine with Pi bonds produced by the macromolecular compound, the structure is steady, and the ion relates to a preparation method for a high-stren
