一种新型玻璃纤维组合物
摘要：
本发明涉及一种玻璃纤维组成物，含有下述组分，基于所述的SiO2、Al2O3、CaO、MgO、B2O3、F2、TiO2、K2O、Na2O、Fe2O3和SO3，各组分的重量百分含量表示如下：SiO2 58～65％，CaO 20～26％，Al2O3 9～17％，MgO 0.5～1％，B2O3 0～5％，F2 0～1％，TiO2 0.1～1％，K2O+Na2O 0～0.8％，Fe2O3 0.1～0.5％，SO3 0～0.6％。本发明的玻璃纤维组合物以SiO2-Al2O3-CaO三元系统为基础，引入低含量的MgO和B2O3，并且合理设计碱土金属氧化物的总量及MgO与CaO的比例关系，不仅有利于改善玻璃的机械强度、耐高温性及化学稳定性，同时还具有良好的拉制性能；并且本发明所述玻璃纤维组合物原料成本低，同时也符合环保要求。
摘要（英）：

The invention relates to a glass fiber composition comprising the following components in percentage by weight: 58 to 65 percent of SiO2, 20 to 26 percent of CaO, 9 to 17 percent of Al2O3, 0.5 to 1 percent of MgO, 0 to 5 percent of B2O3, 0 to 1 percent of F2, 0.1 to 1 percent of TiO2, 0 to 0.8 percent of K2O+Na2O, 0.1 to 0.5 percent of Fe2O3, and 0 to 0.6 percent of SO3. The glass fiber composition uses SiO2-Al2O3-CaO three-element system as basis, introduces low content of MgO and B2O3, and reasonably designs the total weight of alkaline metal oxides and the proportional relationship between the MgO and the CaO, which not only contributes to the improvement of the mechanical strength, the high temperature resistance and the chemical stability of the glass, but also has excellent drawing performance; furthermore, the glass fiber composition has low cost in raw materials, and meets the requirement of environmental protection.
