| 中文摘要: |
| 采用低锌活性剂SA-1作为丁苯橡胶(SBR)胶料的硫化活性剂,研究其用量对SBR硫化胶物理性能、耐热空气老化性能和动态力学性能的影响,同时与普通氧化锌997进行对比。结果表明:活性剂SA-1在SBR基体中的分散性优于氧化锌997;活性剂用量较大(3~5份)时,采用活性剂SA-1的SBR硫化胶具有较出色的物理性能和耐热空气老化性能;随着活性剂SA-1和氧化锌997用量的减小,SBR硫化胶的物理性能和耐热空气老化性能均有下降,与氧化锌997相比,活性剂SA-1可以在用量更小时保持SBR硫化胶的物理性能;采用活性剂SA-1的SBR硫化胶具有更好的抗湿滑性能,同时滚动阻力无明显增大。 |
| 英文摘要: |
| Low zinc activator SA-1 was used as the vulcanizing activator of styrene-butadiene rubber
(SBR) compound,and the effects of its amount on the physical properties,hot-air aging resistance and
dynamic mechanical properties of SBR vulcanizate were studied and compared with ordinary zinc oxide 997.
The results showed that the dispersibility of activator SA-1 in the SBR matrix was better than that of zinc
oxide 997.When the amount of activator was large(3 ~ 5 phr),the SBR vulcanizate with activator SA-1
had excellent physical properties and hot-air aging resistance.With the decrease of the amount of activator
SA-1 and zinc oxide 997,the physical properties and hot-air aging resistance of the SBR vulcanizate were
decreased. However,compared with zinc oxide 997,activator SA-1 could maintain the physical properties
of the SBR vulcanizate when the amount of activator was small. It was also found that by replacing ordinary
zinc oxide 997 with activator SA-1,the wet skid resistance of the SSBR vulcanizate was improved,while the
rolling resistance did not increase significantly. |
