摘要
采用丁异戊橡胶作为主体材料,从补强体系、硫化体系和增塑剂三个方面分析了它们对橡胶高低温性能、耐老化性能和耐压性能的影响.粒径小、结构度高的炭黑和气相白炭黑并用可有效改善橡胶的力学性能;硫磺含量在0.8％ ～1.3％使得硫化橡胶既具备较好的高低温性能又兼顾较好的耐老化性能;增塑剂可有效调整橡胶硬度和耐压性能.并对研制的丁异戊橡胶弹性材料及其柔性接头构件耐高低温性能及耐压性能进行分析.结果表明,弹性材料高低温剪切性能及耐压性能表征结果能初步反映柔性接头构件的摆动性能及耐压性能.
The work of this paper was focused on the effect of reinforcement,cure system and plasticizer on properties of vulcanized butadiene-isoprene rubber resilient material.The result showed that the resilient material had better mechanical property reinforced by the carbon black N330 or N220 than carbon black N770,according to the specific surface.With the addition of 0.8 to 1.3 parts sulfur,the resilient material had desirable characteristics at40 to ＋60℃.The hardness and modulus of resilient material can be adjusted by adding of plasticizer.Furthermore,the property of the resilient material and the operational performance on flexible bearing were compared,the result showed that the shear properties at-40 to ＋60℃ and compress properties of the resilient material could represent the swing properties and compress properties of flexible bearing.
