| Abstract: |
| The effect of curing system on the flexural resistance of natural rubber/butadiene rubber blend
was studied. The results showed that the ratio of sulfur and accelerator，and the type of accelerator had a
significant influence on the properties of the compound. The ratio of single sulfur bonds formed by using high
accelerator and low sulfur system was high，but the flexural resistance of the compound was poor. The ratio of
polysulfur bonds formed with low accelerator and high sulfur system was large，and the flexural resistance of
the compound was improved. Compared with accelerator TBBS，accelerator CBS，TiBTD and DTDM all had
adverse effects on the flexural resistance of the compound. |
