CN107459260A 一种以粉煤灰为主要原料的玻璃纤维及其制备方法 无效 - 驳回

一种以粉煤灰为主要原料的玻璃纤维及其制备方法
摘要：
本发明涉及一种以粉煤灰为主要原料的玻璃纤维及其制备方法，本发明的以粉煤灰为主要原料的玻璃纤维，包括以下质量百分比的原料组分：粉煤灰25-75％、石英砂5-30％、方解石5-25％、白云石0～5％、其他成分5-20％。本发明将所述质量配比的原料组分混合、研磨后加入添加剂得到混合料，进行熔制得到玻璃液，水淬后得到粉煤灰玻璃，经清洗、挑选、去污后，进行拉丝、烘干得到终产物玻璃纤维。本发明制备得到的玻璃纤维强度高、抗腐蚀、耐高温，且实现整个产业链的节能环保，具有非常大的经济效益、环境效益和社会效益，同时也具有非常好的发展前景。
摘要（英）：

The invention relates to glass fiber mainly from flyash and a preparation method thereof. The glass fiber mainly from flyash comprises, by weight, 25-75% of flyash, 5-30% of quartz sand, 5-25% of calcite, 0-5% of dolomite, and 5-20% of other ingredients. The ingredients having the above ratio are mixed and ground, additives are added to the ground mixture to obtain a mixture, the mixture is melted obtain molten glass, the molten glass is water-quenched to obtain flyash glass, the flyash glass is subjected to washing, selecting and cleaning are then performed, and drawing and drying are finally performed to obtain the finished glass fiber. The glass fiber prepared herein has high strength, good corrosion resistance and good resistance to high temperature; a whole industry chain is energy efficient and environmentally friendly; the glass fiber has great economic benefit, environmental benefit and social benefit, and has a very promising development prospect.
