| 中文摘要: |
| 改进农用机械橡胶履带胶料的配方，采用炭黑/白炭黑并用补强体系，并添加少量抗撕裂助剂，以提高橡胶履带胶料的抗切割性能。结果表明，与生产配方胶料相比，改进配方胶料的门尼粘度和焦烧时间相近，FL和Fmax减小，300%定伸应力和500%定伸应力稍有提高，拉伸强度、撕裂强度和耐老化性能相近，拉断伸长率降低，抗切割性能提高，这有助于解决橡胶履带沟底裂的早期损坏问题。 |
| 英文摘要: |
| 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. |
