  • Solution polymerized styrene-butadiene rubber-polyurethane elastomer material for high performance tire and preparation method thereof
    Patent number: 10717854
    Abstract: A solution polymerized styrene-butadiene rubber-polyurethane elastomer material and a preparation method thereof are provided. The elastomer material is prepared by performing cast molding on a soft segment and a hard segment in a mass ratio of 100:(20-50); the soft segment includes hydroxyl-terminated solution polymerized styrene-butadiene moiety rubber prepared by an anionic polymerization; the hard segment comprises isocyanate, a small-molecule polyol chain extender and a cross-linking agent; and the soft segment has a molecular weight of 1000-8000 and a glass-transition temperature of ?20° C. to ?30° C.
