摘要
研究白炭黑和硅藻土对丁基橡胶（IIR）加工性能、物理性能和动态力学性能的影响。结果表明：与硅藻土相比,随着加工时间的延长,白炭黑填充IIR胶料的加工性能较优,硫化胶的邵尔A型硬度和拉伸强度较高,拉断伸长率较低;在低温阶段,白炭黑填充IIR硫化胶的储能模量（E′）较大,而在高温阶段,两种填料填充IIR硫化胶的E′相当;当频率为0.1~200 Hz时,白炭黑填充IIR硫化胶的损耗因子较大,E′在低频（〈150 Hz）时较小,而在高频（≥150 Hz）时则较大。
The effects of silica and diatomite on the processability,physical properties and dynamic mechanical property of IIR were investigated. The results showed that,compared with diatomite,as the processing time extended,the processability of IIR compound filled with silica was better,the Shore A hardness and tensile strength of the vulcanizate were higher,and the elongation at break was lower. The storage modulus（E′） of IIR vulcanizate filled with silica at low temperature was higher,while the E′ of IIR vulcanizate filled with silica and diatomite at high temperature was similar. When the frequency range was 0. 1～200 Hz,for the silica filled IIR vulcanizate,the loss factor was higher,and the E′ at low frequency（〈150 Hz） was lower,while the E′ at high frequency（≥150 Hz） was higher.
