Nano SiO2 modified basalt fiber material and preparation method thereof
The invention relates to the technical field of basalt fiber, and discloses a nano SiO2 modified basalt fiber material and a preparation method thereof, the nano SiO2 modified basalt fiber material comprises SiO2-coated basalt fiber, polyamino acid composite fiber and porous silicon particles; the polyamino acid composite fiber comprises a regular molecular chain formed by connecting same amino acids through peptide bonds and an irregular molecular chain formed by connecting different amino acids through peptide bonds. The polyamino acid composite fibers are additionally arranged between basalt fiber base material layers, the polyamino acid composite fibers contain regular molecular chains and irregular molecular chains at the same time, so that the fiber material can be endowed with good toughness and strength, and the polyamino acid composite fibers are combined between the basalt fiber base materials through the porous structure particles; the problems that the toughness of the existing basalt fiber material is unstable and reduced in the using process can be solved.
本发明涉及玄武岩纤维技术领域，公开了一种纳米SiO2改性玄武岩纤维材料及其制备方法，所述纳米SiO2改性玄武岩纤维材料包括SiO2@玄武岩纤维、多聚氨基酸复合纤维和多孔硅颗粒；所述多聚氨基酸复合纤维中包含由同种氨基酸经肽键连接而成的规则分子链、以及由不同氨基酸经肽键连接而成的不规则分子链。通过在玄武岩纤维基料层间增设多聚氨基酸复合纤维，由于多聚氨基酸复合纤维中同时含有规则分子链和不规则分子链，可赋予纤维材料良好的韧性和强度，并通过多孔结构颗粒将多聚氨基酸复合纤维结合于玄武岩纤维基料间，可改善现有玄武岩纤维材料在使用过程中出现韧性不稳定和下降的问题。
