选用氯丁橡胶(CR)作为铁道轨枕垫的胶料,通过单因素实验考查不同牌号的氯丁橡胶、填充剂、防老剂和硫化体系,研究了作为铁道轨枕垫的氯丁橡胶胶料的力学性能、老化性能及尺寸稳定。研究结果表明:选用调节剂丁(二硫化二异丙基黄原酸酯)调节型氯丁橡胶,防老剂RD和防老剂MB并用,多种填充剂并用,采用MgO/ZnO金属氧化物硫化体系,研制出的铁道轨枕垫的综合力学性能最佳,满足了产品的技术要求。 The neoprene (CR) was selected as the rubber compound for railway sleeper cushion, and the mechanical properties of the neoprene rubber compound as rail sleeper cushion were studied by single factor experiments on the different grades of neoprene, filler, antioxidant and vulcanization system Performance, aging properties and dimensional stability. The results show that: the regulator of butyl (diisopropyl xanthogen disulfide) conditioning neoprene, antioxidant RD and antioxidant MB used in combination with a variety of fillers, the use of MgO / ZnO metal oxide curing system , Developed the railway track pad the best comprehensive mechanical properties to meet the technical requirements of the product.
