| 中文摘要: |
| 研究环氧化天然橡胶（ENR）用量对天然橡胶（NR）/ENR复合材料性能的影响。结果表明：ENR与NR并用后，NR/ENR复合材料的阻尼因子（tanδ）最大值和阻尼温域（tanδ＞0.3）增大，tanδ最大值对应温度向低温方向移动；随着ENR用量的增大，NR/ENR复合材料的邵尔A型硬度、拉伸强度和拉断伸长率呈减小趋势，100%定伸应力呈增大趋势；当ENR用量为10份，NR/ENR复合材料的tanδ最大值对应温度在25 ℃附近，其综合性能最佳。 |
| 英文摘要: |
| The effect of epoxidized natural rubber（ENR）dosage on the properties of natural rubber
（NR）/ENR composites was studied. The results showed that after ENR and NR were blended，the maximum
damping factor（tanδ） and damping temperature range（tanδ＞0. 3） of the NR/ENR composites increased，
and the temperature corresponding to the maximum tanδ moved to a lower temperature. As the dosage of
ENR increased，the shore A hardness，tensile strength and elongation at break of the NR/ENR composites
tended to decrease，and the modulus at 100% elongation showed an increasing trend. When the ENR dosage
was 10 phr，the temperature corresponding to the maximum tanδ of the NR/ENR composites was around 25
℃，and its comprehensive properties were the best. |
