摘要
对CRH2046A动车组用橡胶密封垫的防护体系进行研究,改变橡胶密封垫配方中的防老剂品种,进行热空气加速老化试验,通过数理统计方法进行橡胶密封垫使用寿命预测。结果表明:与单独使用1.5份防老剂4010相比,防老剂4010和防老剂RD并用比为1/0.5时,橡胶密封垫的使用寿命显著提高。
The antioxidant system of rubber gasket in CRH2046 A EMU was studied,different antioxidants were tested in the rubber gasket formula by using hot air accelerated aging experiment,and then the service life of the rubber gasket was predicted using mathematical statistics model. The results showed that,compared with 1. 5 phr antioxidant 4010 alone,the combination of antioxidant 4010 and antioxidant RD by a blending ratio of 1/0. 5 could greatly improve the service life of the rubber gasket.
