三元乙丙橡胶耐磨性能研究

Study on the Abrasion of EPDM Rubblers

摘要: 研究了生胶品种、硫化体系、填充体系和加工助剂等因素对三元乙丙橡胶耐磨性能的影响。实验结果表明:胶种选用高乙烯含量,高门尼粘度的非充油型乙丙橡胶,硫化体系采用硫磺/硫载体并用的有效硫磺硫化体系,填充体系采用高结构炭黑N220以及Si-69改性过的气相法白炭黑AS-200并用体系,同时配合0.5份左右的爽滑粉,都能有效提高EPDM胶料的耐磨性能。

Abstract: The effects of the raw rubber variety,curing system,filling systems and processing aids and other factors on the abrasion of EPDM were studied.The results of experiments show that with high ethylene content and Mooney viscosity non-oil-filled EPDM as raw rubber,sulfur/sulfur carrier as curing system,carbon black(N220) and Si 69 modified fumed silica(AS-200) as filler,plus 0.5 phr smooth powder,the abrasion of EPDM is improved.
