Preparation method of alkali-resistant basalt fiber for cement-based cementing material
The invention discloses a preparation method of alkali-resistant basalt fiber for a cement-based cementing material, which comprises the following steps: mixing basalt and an additive through ball milling to obtain a basalt fiber raw material; the preparation method comprises the following steps: gradually heating a basalt fiber raw material to 1350-1600 DEG C, and homogenizing for 5-10 hours to obtain a basalt melt; the basalt melt is quenched, and basalt glass is obtained; basalt glass is subjected to wire drawing under the condition of 1250-1450 DEG C to generate hot fibers, the hot fibers are modified to obtain the alkali-resistant basalt fibers, and the modification is that the hot fibers are coated with the alkali-resistant slurry in the wire drawing process. The alkali resistance of the basalt fiber can be improved, and the effect of long-term performance stability of the basalt fiber reinforced cement-based material is achieved.
本发明公开了一种水泥基胶凝材料用耐碱玄武岩纤维的制备方法，包括将玄武岩和添加料经球磨混合，得到玄武岩纤维原料；将玄武岩纤维原料逐步加热至1350‑1600℃，再均质5‑10h得到玄武岩熔体；将玄武岩熔体进行淬火，得到玄武岩玻璃；将玄武岩玻璃在1250‑1450℃的条件下进行拉丝产生热纤维，并对热纤维进行改性得到耐碱玄武岩纤维，所述改性为在拉丝过程中将耐碱浆料涂覆于热纤维上。本发明可以改善玄武岩纤维的耐碱性，实现玄武岩纤维增强水泥基材料的长期性能稳定性的效果。
