Abstract:
      The formula of rubber track compound for agricultural machinery was modified by using carbon black/silica blending reinforcement system and adding a small amount of tear resistant additives，to improve the cutting resistance of rubber track compound.The results showed that，compared with the production formula compound，the Mooney viscosity and scorch time of the improved formula compound were similar，FL and Fmax were reduced，the modulus at 300% elongation and modulus at 500% elongation slightly increased，the tensile strength，tear strength and aging resistance were similar，the elongation at break was reduced，and the cutting resistance was improved，which helped to solve the early damage problem of rubber track groove bottom cracks.
