二氧化硅超细短纤维/氯丁橡胶复合材料的结构与性能

Structure and Properties of Superfine SiO_2 Short Fiber/CR Composite

利用静电纺丝技术制备二氧化硅超细短纤维(n-SF),采用偶联剂KH-570对其进行改性,再制备改性n-SF(n-MSF)/氯丁橡胶(CR)复合材料,并对复合材料的结构和性能进行研究。结果表明:n-MSF在CR基体中分散均匀,与CR界面结合良好;加入适量的n-MSF,复合材料的定伸应力、撕裂强度及抗溶胀能力明显提高,动态力学性能有所改善。

The superfine SiO2 short fiber（n-SF） prepared via electrospinning method was modified by coupling agent KH-570,then the modified n-SF（n-MSF）/CR composite was prepared,and its struc- ture and properties were investigated. The results showed that the n-MSF was uniformly dispersed in CR matrix,and the interracial adhesion between n-MSF and CR was good; the modulus, tear strength and swelling resistance of composite increased significantly by adding proper level of n-MSF, and the dynamic mechanical property improved.
