| 中文摘要: |
| 对纸管高速平带强力层和覆盖胶配方进行优化。结果表明，纸管高速平带强力层采用高模量低收缩聚酯钢化棕丝替代普通聚酯线绳，覆盖胶主体材料采用天然橡胶/丁苯橡胶/顺丁橡胶并用（并用比为50/20/30），补强体系采用白炭黑/补强剂JC-069/硅粉B-66并用，粘合体系中减小古马隆用量及添加动态粘合剂LP-600和增粘树脂502，添加助硫化体系（苯甲酸/偶联剂Si69/抗硫化返原剂TDB680并用体系）、耐疲劳体系（耐疲劳剂HG-90/抗撕裂树脂HR-801并用体系）和耐磨剂JTH-315，覆盖胶耐疲劳性能和耐磨性能提高，生热降低，平带线绳和帆布粘合性能改善，平带使用寿命超过进口产品。 |
| 英文摘要: |
| In this study，the formulations for the compounds for high strength layer and cover layer of high-speed rubber flat belt were optimized. For the high strength layer，high-modulus and low-shrinkage pre-stretched polyester monofilament was used to replace ordinary polyester cord. For the cover layer，blend of natural rubber（NR）/styrene butadiene rubber（SBR）/butadiene rubber（BR） blend with the blending ratio of 50/20/30 was used as the matrix material，and silica，reinforcing agent JC-069 and silicon powder B-66 were applied as reinforcement. In the adhesion system the addition level of coumarone resin was reduced and dynamic adhesive additive LP-600 was added. Cure co-agent system of benzoic acid，coupling agent Si69 and anti-reversion agent TDB680 was applied，and anti-fatigue additive system composing of anti-fatigue additive HG-90 and tear resistant additive HR-801 was also added with anti-wear agent JTH-315 as well.With the optimization，the fatigue resistance and abrasion resistance of the cover rubber were improved，heat build-up was reduced and the adhesion between cords and belt compound was improved. It was found that the service life of optimized belt was longer than that of imported products. |
