一种高强度玻璃纤维组合物
摘要：
本发明公开了一种高强度玻璃纤维组合物，含有下述组分，基于所述的SiO2、Al2O3、CaO、MgO、K2O、Na2O、Fe2O3和CeO2，各组分的含量以重量百分比表示如下：SiO258～65％，Al2O314～20％，CaO+MgO 15～25％，K2O+Na2O 0.05～1％，Fe2O30.05～1％，CeO20.1～2％，其中，组分含量遵循如下比例关系：0.7＜CaO/MgO＜2.2。本发明通过对组分的优选和组合，在保证玻璃纤维高强度的前提下，它既能充分利用我国丰富的矿物原料，又能实现成型温度、液相线温度及澄清温度的降低，且总体成本较低，易于实现大规模工业化生产。
摘要（英）：

The invention discloses a high strength glass fiber composition which comprises the components with the weight percentage: 58-65% of SiO2, 14-20% of Al2O3, 15-25% of CaO+MgO, 0.05-1% of K2O+Na2O, 0.05-1% of Fe2O3 and 0.1-2% of CeO2; wherein, the proportional relation of the components is that CaO/MgO is more than 0.7 and less than 2.2. By preference and combination of the components, the high strength glass fiber composition not only can fully utilize rich raw mineral materials of China, but also can reduce mold temperature, liquidus temperature and clarification temperature and has lower total cost and easy large scale commercial process under the premise of ensuring the high strength of glass fiber.
