| 中文摘要: |
| 介绍促进剂CBS-80预分散母胶粒的研制。促进剂CBS-80预分散母胶粒的优化配方为：促进剂CBS粉体 80，三元乙丙橡胶（EPDM K4551A） 11，乙烯-醋酸乙烯共聚物（乙酸乙烯酯质量分数为0.26） 4.7，表面改性剂YZ 0.3，环烷油（10#或15#白油） 4；混炼温度和时间分别为50 ℃和720 s；促进剂CBS-80预分散母胶粒中CBS粉体分散均匀，母胶粒与橡胶的相容性好，使用性能与促进剂CBS粉体相当。使用促进剂CBS-80预分散母胶粒可以大幅缩短胶料混炼时间，提高混炼效率。 |
| 英文摘要: |
| The accelerator CBS was pre-dispersed in masterbatch and the optimized formulation was as follows：accelerator CBS 80，EPDM K4551A 11，EVA（VA content of 0.26） 4.7，surface modifier YZ 0.3，naphthenic oil（10# or 15# white oil） 4.The mixing temperature and time were 50 ℃ and 720 s，respectively.It was found that accelerator CBS was uniformly dispersed in the masterbatch，the compatibility between masterbatch and rubber was good，and the application property of the masterbatch was pretty similar as accelerator CBS powder.Use of accelerator CBS pre-dispersed masterbatch could significantly shorten the compound mixing time and improve efficiency. |
