一种无硼高性能玻璃纤维及其制备方法
摘要：
本发明公开了一种无硼高性能玻璃纤维，其原料按重量份如下：ZnO 5-12份、MgO 7-15份、CaO 15-20份、助剂2-6份、SiO2 30-40份、Al2O3 15-20份、K2O 4-6份、TiO2 10-20份和SrO 0.5-1.5份。以SiO2、Al2O3、MgO为主，同时加入了Li2O、Bi2O3和Fe2O3的助剂，成功熔制出新型高强度玻璃，并制备了其相应高强度玻璃纤维。制备的新型高强度玻璃纤维，其新生态强度为4800～5000MPa、软化点温度为965～970℃。玻璃纤维的耐热温度明显提高，玻璃纤维的耐热性能大大提高，能够满足现有市场的需求，且生产工艺简单，生产条件易满足，生产效率高。
摘要（英）：

The invention discloses boron-free high-performance glass fiber which comprises, by weight, 5-12 parts of ZnO, 7-15 parts of MgO, 15-20 parts of CaO, 2-6 parts of auxiliaries, 30-40 parts of SiO2, 15-20 parts of Al2O3, 4-6 parts of K2O, 10-20 parts of TiO2 and 0.5-1.5 parts of SrO. Novel high-strength glass is successfully obtained by taking SiO2, Al2O3 and MgO as main ingredients and Li2O, Bi2O3and Fe2O3 as auxiliaries for melting, and corresponding high-strength glass fiber of the glass is prepared. Nascent-state strength of the novel high-strength glass fiber is 4800-5000MPa, and softeningpoint temperature is 965-970 DEG C. Heat-resistant temperature of the glass fiber is increased obviously, heat resistance of the glass fiber is improved greatly, needs of existing market can be met,and the glass fiber is simple in production process, easy-to-meet in production condition and high in production efficiency.
