Beschreibung
Zusammenfassung:	The invention provides a soluble basalt fiber. The soluble basalt fiber is prepared from the following raw materials in percentage by mass: 40-50wt% of SiO2; al2O3: 15 to 25 wt%; caO: 15 to 22 wt%; mgO: 7 to 13 wt%; less than 4% of K2O + Na2O; 3 to 11 wt% of total Fe; the molar ratio of O to Si is 3.4 to 3.8; and 4-12% of K2O, Na2O and total Fe. By regulating and controlling the total Fe (FeO + Fe2O3) content, the dosage ratio of Fe (FeO + Fe2O3) to K2O + Na2O and the O/Si ratio, the flexural strength of the fiber is improved (expressed by the tensile strength of the blanket), and the diameter of the fiber is reduced. The invention also provides a preparation method of the soluble basalt fiber and a soluble basalt fiber blanket. 本发明提供了一种可溶性玄武岩纤维，由以下质量分数的原料制成：SiO2：40～50wt％；Al2O3：15～25wt％；CaO：15～22wt％；MgO：7～13wt％；K2O+Na2O：＜4％；总Fe：3～11wt％；O与Si的摩尔比为3.4～3.8；K2O+Na2O+总Fe：4～12％。本发明通过调控总Fe(FeO+Fe2O3)含量以及其与K2O+Na2O的用量配比以及O/Si比，提高纤维的挠曲强度(通过毯的抗拉强度表现)，并降低纤维的直径。本发明还提供了一种可溶性玄武岩纤维的制备方法和可溶性玄武岩纤维毯。
