The present invention discloses a solution polymerized styrene-butadiene rubber-polyurethane elastomer material for a high-performance tire and a preparation method thereof. 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 is hydroxyl-terininated solution polymerized styrene-butadiene 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 According to the elastomer material in the invention, the hydroxyl-terminated solution polymerized styrene-butadiene rubber is introduced to serve as the soft segment on the basis of synthesis of the traditional polyurethane elastomer, so that the glass-transition temperature of the polyurethane elastomer is regulated, defects such as poor high temperature resistance and undesirable wet-skid resistant grip ability of an existing polyurethane tire are overcome, and the prepared tire has excellent comprehensive application property.
