| 中文摘要: |
| 研究天然橡胶（NR）/丁苯橡胶（SBR）/高苯乙烯橡胶HS60（简称HS60）和SBR/HS60复合材料的阻尼性能和物理性能。结果表明：HS60可以有效提高复合材料在高温段的阻尼性能，增大复合材料的硬度和定伸应力，HS60可作为增强相代替炭黑；HS60与NR的相容性不佳，但与SBR的相容性较好，HS60用量增大可使SBR/HS60复合材料的拉伸强度和撕裂强度增大；当SBR/HS60并用比为60/40时，SBR/HS60复合材料的有效阻尼温域拓宽至－11～94 ℃，符合阻尼橡胶材料的要求。 |
| 英文摘要: |
| The damping properties and physical properties of natural rubber（NR）/styrene-butadiene rubber（SBR）/high styrene rubber HS60（abbreviated as HS60） and SBR/HS60 composites were studied.The results showed that，HS60 could effectively improve the damping properties of the composites at high temperature range，and increase the hardness and stress at a given elongation of the composites as a reinforcing phase instead of carbon black.HS60 exhibited poor compatibility with NR but good compatibility with SBR，with the increase of HS60 amount，the tensile strength and tear strength of the SBR/HS60 composite were improved.When SBR/HS60 blending ratio was 60/40，the effective damping temperature range of SBR/HS60 composite was expanded to －11 to 94 ℃，meeting the requirements of damping rubber materials. |
