Title:
GLASS FIBER COMPOSITION AND GLASS FIBER AND COMPOSITE MATERIAL THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/041581
Kind Code:
A1
Abstract:
Disclosed are a glass fiber composition and a glass fiber and a composite material thereof, wherein the content of each component of the glass fiber composition is as follows (expressed in mass percentages): 57.4%-60.9% of SiO2, greater than 17% and less than or equal to 19.8% of Al2O3, greater than 9% and less than or equal to 12.8% of MgO, 6.4%-11.8% of CaO, 0-1.6% of SrO, 0.1%-1.1% of Na2O+K2O, 0.05%-1% of Fe2O3, less than 0.8% of TiO2, and less than or equal to 79.4% of SiO2+Al2O3, and the total content of the components mentioned above is greater than 99%. The range of the ratio of weight percentages of C1＝(Al2O3+MgO)/SiO2 is from 0.43 to 0.56, and the range of the ratio of weight percentages of C2＝(CaO+MgO)/(SiO2+Al2O3) is greater than 0.205. The glass fiber composition can improve the modulus of glass fibers, and reduce the crystallization rate of glass, so as to obtain an ideal ΔT value of a glass fiber forming range, can improve the clarification effect of glass, and is suitable for the production of high performance glass fibers in a tank furnace.
