摘要

采用高混的方法对芳纶短纤维和玄武岩短纤维与改性高岭土和硅烷偶联剂进行改性共混,通过改变芳纶短纤维长度和芳纶短纤维/玄武岩短纤维并用比,系统地研究了芳纶短纤维/玄武岩短纤维共混后对EPDM分散特性及其他物理性能影响。结果表明:随着芳纶短纤维/玄武岩短纤维共混比的降低,门尼黏度降低;沿纤维取向和垂直两个方向上拉伸强度、拉断伸长率、撕裂强度均增加,硬度逐渐减小,耐磨性能增加;储能模量逐渐降低,Payne效应减小。1 mm芳纶短纤维分散性和基本的物理性能优于3 mm芳纶短纤维,储能模量不如3 mm芳纶短纤维高。
        High mixing method is used for modified blending of aramid short fibers/basalt short fibers with modified kaolin and silane coupling agents. By changing the length of aramid short fiber and the ratio of aramid short fiber to basalt short fiber, the effects of aramid short fiber/basalt short fiber blend on EPDM dispersion and other physical properties are systematically studied in this paper. The results show that: With the aramid fiber/basalt fiber blend ratio decreased, the Mooney viscosity decreased; Tensile strength, elongation at break and tear strength increased along two directions of fiber orientation and vertical. Hardness gradually decreased, wear resistance increased; storage modulus decreased and Payne effect decreased. The dispersion and basic physical properties of 1 mm aramid short fibers are better than that of 3 mm aramid short fibers, and the energy storage modulus of 1 mm aramid short fibers is not as high as 3 mm aramid short fibers.
