- 摘要:
- 研究了新型热法聚合丁腈橡胶（NBR）40 H生胶分子结构和玻璃化转变温度、混炼胶门尼黏度和硫化特性、硫化胶耐热氧老化性能和耐油性能，并与传统热法聚合产品NBR 3604进行了对比。结果表明，NBR 40 H的分子结构与NBR 3604差异不大，二者玻璃化转变温度和加工性能均相近，热氧老化和在标准参比油中浸泡后力学性能保持率相近；NBR 40 H可以替代NBR 3604。
- Abstract:
- Molecule structure and glass transition temperature of raw rubber of the new nitrile rubber (NBR) 40 H by hot polymerization, and Mooney viscosity and curing characteristics of the compound, as well as thermal-oxidative aging resistance and oil resistance of the vulcanizates, were studied and compared with the traditional hot polymerized product NBR 3604. The results showed that the molecule structure of NBR 40 H was not significantly different from that of NBR 3604, both had similar glass transition temperatures and processing properties, and the mechanical property retention rates after thermal-oxidative aging and immersed in standard refe-rence oil were also similar. NBR 40 H could replace NBR 3604.
