A blend of modified rubber

The invention discloses a blend modified rubber material which contains one or a plurality of polyurethane (PU) rubbers and one or a plurality of other types of rubbers. The uncured PU rubber is compounded with other types of unvulcanized rubbers, and is cured or vulcanized to obtain the blend modified rubber material. The blend modified rubber material is composed of the polyurethane rubber (PU) and other rubbers. The PU material is utilized to enhance the abrasion resistance of the rubber, and the polyurethane rubber is blended with other types of rubbers to improve the tearing strength under high-temperature conditions, thereby enhancing the comprehensive properties of the rubber material.
