摘要
用硅烷偶联剂KH-550对不同品种的玄武岩纤维进行表面改性处理,采用单丝拉伸试验,结合扫描电镜和SPSS统计分析的方法,研究了硅烷偶联剂处理对玄武岩单丝拉伸性能的影响.结果表明:表面处理前后,玄武岩纤维品种2和3的拉伸强度和断裂伸长率均没有显著变化;玄武岩纤维品种1的拉伸强度和断裂伸长率明显增大,其拉伸强度提高32.8%,断裂伸长率增大31.79%.这证明用硅烷偶联剂KH-550对玄武岩纤维进行表面改性处理,可以达到表面处理的目的且不损伤玄武岩单丝的拉伸性能,一定程度上可以弥补玄武岩纤维生产工艺的不足.
In order to study the effect of silane coupling agent treatment on the tensile properties of single basalt filament, the surface of different kinds of basalt fibers is treated with silane coupling agent KH-550. Single filament tensile test is applied, combined with scanning electron microscopy and SPSS statistical analysis methods. The results show that： pre-and post-surface treatment, the tensile strength and elongation at break of second type and the third type of basah fibers does not significantly change, whereas these properties of the first type of basalt fiber are remarkably improved. The tensile strength of the first type increases up to 32.8%, and elongation at break go up around 31.79%. This proves that treating the basalt fiber with silane coupling agent KH-550, the purpose of surface treatment could be achieved without damage of tensile strength and elongation properties of basalt single filament, and the surface treatment can make up for the lack of basalt fiber production process in a certain extent.
