加工助剂对棉短纤维/三元乙丙橡胶复合材料性能的影响

Effects of Processing Aids on Properties of Short Cotton Fiber/EPDM Composites

研究加工助剂TKM-80、60NSF和蒎烯树脂对棉短纤维/三元乙丙橡胶复合材料性能的影响。结果表明:3种加工助剂对复合材料ts1,t10和t50影响不大,加入蒎烯树脂的复合材料t90延长,而加入60NSF的复合材料t90缩短;随着加工助剂用量的增大,复合材料的ML减小,加工性能改善;加入6份60NSF的复合材料剪切储能模量低于未加入加工助剂的复合材料,其综合物理性能优于加入TKM-80或蒎烯树脂的复合材料。

The effects of processing aid TKM-80,60NSF and pinene resin on the properties of short cotton fiber/EPDM composites were investigated. The results showed that, three processing aids had little effect on the tst ,t10 and t50 of composites, and the t90 was extended with pinene resin but shortened with 60 NSF. As the addition level of processing aid increased, the ML of composites decreased, the processibility was improved. The storage shear modulus could be reduced by adding 6 phr of 60NSF, and the comprehensive physical properties with 60NSF were better than those with TKM-80 or pinene resin.
