| 中文摘要: |
| 研究高模量低收缩聚酯线绳作骨架材料的V带底胶配方。结果表明：V带底胶主体材料采用天然橡胶（NR）/顺丁橡胶（BR）并用（并用比70/30）、助硫化体系采用偶联剂Si69/抗硫化返原剂TDB680/苯甲酸并用（并用比1/0.5/2）、补强体系采用炭黑N774/炭黑N550/硅粉B-66/无机补强剂JC-069并用（并用比70/20/50/10），并添加耐疲劳和抗撕裂助剂体系，胶料的物理性能、弹性和耐屈挠性能提高，生热降低，成品V带的耐疲劳性能和粘合性能改善，使用寿命延长。 |
| 英文摘要: |
| The rubber compound formulation for the V-belt with high modulus low shrinkage polyester cords as reinforcing material was studied.In the optimized formulation，the matrix material was NR/BR blend with the blending ratio of 70/30，the co-agents in the curing system were coupling agent Si69，anti-reversion agent TDB680 and benzoic acid，the reinforcing fillers were carbon black N774，carbon black N550，fume silica B-66 and inorganic reinforcing agent JC-069 with the mixing ratio of 70/20/50/10，and additives for better fatigue resistance and tear resistance were also applied.The experimental testing results showed that the physical properties，elasticity，fatigue resistance and adhesion property of the compound were good，and the heat build-up was low.The service life of the V-belt was long with the combination of the optimized rubber compound and high modulus low shrinkage polyester cords. |
