Alkali-resistant material, alkali-resistant glass fiber and preparation method and application thereof

LI PEIXIN

The invention relates to the field of industrial waste recovery, and discloses an alkali-resistant material and alkali-resistant glass fiber as well as a preparation method and application thereof. The alkali-resistant material is a composite oxide containing Ba, Ti and Si; the composite oxide containing the Ba, the Ti and the Si contains BaO, TiO2 and SiO2; wherein the molar ratio of BaO to TiO2 to SiO2 is (0.4-4): (0.6-8): 1. The alkali-resistant material has excellent alkali resistance, the alkali resistance of the alkali-resistant glass fiber obtained by compounding the alkali-resistant material with a waste wind turbine generator composite material is remarkably improved, and the alkali-resistant material is low in cost and suitable for large-scale preparation of a glass fiber reinforced cement-based material.

本发明涉及工业废弃物回收领域，公开了一种耐碱材料和耐碱玻璃纤维及其制备方法和应用。所述所述耐碱材料为含Ba、Ti和Si的复合氧化物；所述含Ba、Ti和Si的复合氧化物中含有BaO、TiO2和SiO2；其中，BaO、TiO2和SiO2的摩尔比为0.4‑4:0.6‑8:1。该耐碱材料具有优异的耐碱性能，与废旧风电机组复合材料进行复合后得到的耐碱玻璃纤维其耐碱性能显著提升，且成本低廉，适宜用于大规模制备玻璃纤维增强水泥基材料。
