| 中文摘要: |
| 研究硫化体系对胶料（天然橡胶/顺丁橡胶并用胶为主体材料）耐屈挠性能的影响。结果表明：硫黄与促进剂
用量比及促进剂品种均对胶料的各项性能产生影响；高促低硫硫化体系生成单硫键比例较大，胶料的耐屈挠性能较差；
低促高硫硫化体系生成多硫键比例较大，胶料的耐屈挠性能提高；与促进剂TBBS相比，促进剂CBS，TiBTD和DTDM均
对胶料的耐屈挠性能存在不利影响。 |
| 英文摘要: |
| 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. |
