| 中文摘要: |
| 研究提高乳胶气囊（用天然胶乳制备）在高伸长率（高充盈）状态下耐疲劳性能的方法。结果表明，采用防老剂CPL和防老剂DTBHQ并用（并用比1/1），增加胶乳预硫化工艺（60 ℃下水浴恒温4 h）和预硫化胶乳离心处理，乳胶气囊的耐疲劳性能明显提高，在700%伸长率下的平均疲劳次数达到85，产品性能可以满足国内市场要求。 |
| 英文摘要: |
| The purpose of this study was to improve the fatigue resistance of latex bladder (prepared by NR latex) under highly inflated condition.The experimental test results showed that，in the optimized formulation and process，the antioxidant CPL and DTBHQ were jointly used at the ratio of 1/1，the latex was pre-vulcanized at 60 ℃ in water bath for 4 h，and the pre-vulcanized latex was treated by centrifugation.The average number of fatigue cycle to failure under 700% elongation reached 85，indicating significantly improved fatigue resistance of the obtained latex bladder.The product performance met the requirements of the domestic market. |
