| 中文摘要: |
| 研究硫化条件和胶料硫化体系对橡胶制品用聚酯线绳强力的影响。结果表明：在硫化温度为150或160 ℃、硫化时间为1～3 h下，干热硫化条件对聚酯线绳强力基本无影响；湿热硫化条件使聚酯纤维有一定程度的水解，造成聚酯线绳强力有所下降，且温度越高、时间越长，强力下降幅度越大，但整体变化不大；湿热硫化条件下，胶料过氧化物硫化体系对聚酯线绳强力影响不大，胶料硫黄硫化体系对聚酯线绳强力有明显不利影响，活性更高的二硫代氨基甲酸盐类促进剂的硫黄硫化体系比秋兰姆类促进剂的硫黄硫化体系的影响更严重。 |
| 英文摘要: |
| The effect of vulcanization conditions and compound vulcanization systems on the strength of polyester cord for rubber product was studied. The results showed that，under vulcanization temperature of 150 or 160 ℃ and vulcanization time of 1 to 3 h，the dry heat vulcanization conditions had basically no effect on the strength of the polyester cord. Under the damp heat vulcanization condition，the polyester fiber was hydrolyzed to a certain extent，resulting in a decrease in the strength of the polyester cord，and the higher the temperature and the longer the time were，the greater the decrease in strength was，but the overall change was not large. Moreover，under the damp heat vulcanization condition，the peroxide vulcanization system of the compound had little effect on the strength of the polyester cord，the sulfur vulcanization system of the compound had a significant adverse effect，and the sulfur vulcanization system with dithiocarbamate accelerators which had higher activity had a more serious impact than that with thiuram accelerators. |
