Abstract Basalt fiber is one of high performance inorganic fibers. As a promising textile material, basalt fiber has to be equipped with a coating to avoid abrasion during the handling and textile process. Starch phosphate sizing agent with different content of phosphate groups were prepared and coated on basalt fiber surface to improve its mechanical properties. The results showed that the fiber surface was successfully covered by a uniform and compact layer and modified by starch phosphates. The breaking force of the optimal sized fiber can be 47.8% higher than that of nonsized fiber, and the breaking elongation was also 12.6% higher than that of the original fiber.

磷酸淀粉施胶剂改善玄武岩纤维力学性能

摘要 玄武岩纤维是一种高性能无机纤维。作为一种很有前途的纺织材料，玄武岩纤维必须配备涂层，以避免在处理和纺织过程中磨损。制备了不同磷酸基团含量的淀粉磷酸酯施胶剂并包覆在玄武岩纤维表面以提高其力学性能。结果表明，纤维表面成功地被均匀致密的层覆盖，并被淀粉磷酸酯改性。最佳上浆纤维的断裂力可比未上浆纤维提高47.8%，断裂伸长率也比原纤维提高12.6%。
