| 摘 要： | 针对硅橡胶具有较高的耐热性,但力学性能差;丁苯橡胶(SBR)力学性能较好,但粘性较差;提出了将硅橡胶与SBR共混,制成共混材料;采用偏光显微镜、傅里叶变换红外光谱、差示扫描量热仪以及力学性能、热老化性能测试手段,研究了甲基乙烯基硅橡胶(MVQ)/SBR共混体系的并用比(质量比)、硫化工艺参数以及顺丁橡胶(BR)的加入对力学性能、耐热老化性能和相容性的影响。结果表明:MVQ与SBR最佳配比为30/70,白炭黑为45份;最佳硫化工艺参数为170℃×10 MPa×30 min。MVQ/SBR并用胶的玻璃化温度为-20℃,MVQ和SBR具有较好的相容性。

| Abstract: | Based on the facts that methyl and vinyl silicon rubber(MVQ) is good in heat resistance but bad in physical property,styrene-butadiene rubber(SBR) is good in mechanical property but bad in cohesion,a new blend was prepared by blending them.By means of Polarized Light Microscopy(PLM),Fourier Transform Infrared Spectroscopy(IR),Differential Scanning Calorimetry(DSC),and mechanical thermal properties testing,the effects of the mass ratio,cure parameters and BR content of cis-polybutadiene rubber(BR) compatibil... |
