| 中文摘要: |
| 研究改性酚醛树脂（牌号RM-1）、马来酸酐接枝三元乙丙橡胶（EPDM-g-MAH）和钴盐粘合剂RC作为相容剂对棉短纤维（SCF）/EPDM复合材料性能的影响。结果表明：加入相容剂后，复合材料的100%定伸应力呈增大趋势，拉伸强度、拉断伸长率和撕裂强度先增大后减小，其中相容剂EPDM-g-MAH的改善效果最好；当相容剂EPDM-g-MAH用量为6份时，随着SCF用量的增大，复合材料的邵尔A型硬度和拉断永久变形逐渐增大，定伸应力呈增大趋势，拉伸强度略有减小，撕裂强度先增大后减小，耐热空气老化性能变化不大。 |
| 英文摘要: |
| The effect of compatibilizer on the properties of short cotton fibers （SCF）/EPDM composites was investigated， and the compatibilizers included modified phenolic resin （RM-1），EPDM-g-MAH and organic composite based on melamine prepolymer（RC）.By adding compatibilizer，the modulus at 100% elongation of the composite generally increased，and the tensile strength，elongation at break and tear strength increased at first and then decreased.It was found that EPDM-g-MAH showed the best compatibilization effect.With 6 phr of EPDM-g-MAH，as the addition level of SCF increased，the Shore A hardness and tensile set at break of the composite increased gradually，the modulus increased，the tensile strength decreased slightly，the tear strength increased at first and then decreased，and the thermal aging property changed a little. |
