Using radial tire rubber(natural rubber) as the main rubber material,and substandard rubber,skim rubber,isoprene rubber and butadiene rubber as the auxiliary rubber varieties,the hybrid rubber with constant and low Mooney viscosity was prepared by dry mixing with inner mixer. The results showed that,the Mooney viscosity of the hybrid rubber was low and constant,which could be kept for more than 8 months. Compared with natural rubber CV60 from Malaysia,the change rate of the Mooney viscosity of the hybrid rubber was lower,the tensile strength was higher,and other performances were equivalent. The hybrid rubber could meet the requirements of domestic rubber products.
