| Abstract: |
| Accelerator TBSI is a primary amine accelerator，which does not produce carcinogenic
nitrosamines during vulcanization. The application performance and environmental performance of the
environmentally friendly accelerator TBSI in compounds were studied. The results showed that compared
with the accelerators DCBS，TBBS and CBS，TBSI had better storage stability，and the compound with
TBSI had higher activation energy of vulcanization reaction，longer scorch time，better processability and
anti-reversion property. TBSI was more suitable for thick products and could be used alone to replace the
accelerator TBBS/anti-scorching agent CTP. Moreover，accelerator TBSI and its compound had better
environmental performance，with lower mass fraction of tert-butylamine and volatile organic compounds. |
