摘要
研究国产星形支化丁基橡胶S-ⅡR1451混炼胶的门尼松弛性能、流变性能、硫化特性以及硫化胶的物理性能和耐热氧老化性能,并与进口ⅡR301胶料进行对比;以S-ⅡR1451为原材料批量制作了半钢轮胎和全钢轮胎用硫化胶囊进行轮胎生产的实际应用评价,并与ⅡR301商用硫化胶囊进行应用对比。结果表明:与ⅡR301胶料相比,S-ⅡR1451胶料的加工性能相近,但具有更低的挤出胀大比,硫化胶的物理性能和耐热氧老化性能均更优;采用S-ⅡR1451胶料制作的硫化胶囊表现出更优异的耐热氧老化性能,使用寿命比采用ⅡR301胶料的硫化胶囊提高20%以上。
In this study,the Mooney relaxation,rheological properties,vulcanization characteristics of the domestic star-branched butyl rubber S-IIR1451 compounds,and the physical properties and thermal oxidative aging resistances of the S-IIR1451vulcanizates were investigated,and compared with those of imported product IIR301. The tire curing bladders made from S-IIR1451 were experimentally applied in the production of semi-steel and all steel tires,and compared with those from IIR301. The results showed that the S-IIR1451 compounds displayed lower die swell with similar processing properties compared with IIR301, and the S-IIR1451 vulcanizates possessed better physical properties and thermal oxidative aging resistance than those of IIR301. The experimental tire bladders made from S-IIR1451 exhibited superior thermal oxidative aging resistance and their service life was higher by 20% or more than that of tire bladders made from IIR301.
