| 摘 要： | 该文研究了高乙烯基锡偶联型SSBR、NR、BR3种胶料的相容性及共混硫化胶的性能。结果表明：SSBR、NR及BR在一定的比例下，具有较好的相容性，DMA曲线上只有1个玻璃化转变，当SSBR／BR／NR的比例为20：30：50时，共混硫化胶的
M300、断裂伸长率和断裂时的拉伸疲劳次数最大，力争陛能较好。SSBR／BR／NR3种胶料共混有效地改善了NR的耐磨耗性能和抗湿滑性能，而对滚动阻力影响不大。

| Abstract: | The compatibility and the properties of the blends of high-vinyl SSBR ( solution styrene-butadiene rubber), BR (butadiene rubber) and NR (natural rubber) are studied. The results show that SSBR, BR and NR are compatible in a definite proportion. There is only one glasstransition temperature in the DMA curve. M300 elongation at break and fatigue cycles of the blends and vulcan-izates are the best when the ratio of SSBR/ BR/ NR is 20: 30:50. Blending with SSBR/BR, the anti-abrasion property and wet skid resistance of NR are improved while the rolling resistance of NR is only affected slightly. |
