Title:
ELECTRONIC-GRADE GLASS FIBER COMPOSITION, GLASS FIBER AND ELECTRONIC CLOTH THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/056679
Kind Code:
A1
Abstract:
An electronic-grade glass fiber composition, a glass fiber and an electronic cloth thereof. The electronic-grade glass fiber composition contains the following components, and the content of the components is represented by weight percentage as follows: SiO2 is 54.2-60%, Al2O3 is 11-17.5%, B2O3 is 0.7-4.5%, CaO is 18-23.8%, MgO is 1-5.5%, RO=CaO+MgO is less than or equal to 24.8%, R2O=Na2O+K2O+Li2O is less than 1%, TiO2 is 0.05-0.8%, Fe2O3 is 0.05-0.7%, F2 is 0.01-1.2%, and the range of weight percentage ratio C1=SiO2/(RO+R2O) is greater than or equal to 2.20, the total content of the described components is 98.5% or more. The electronic-grade glass fiber composition has the characteristics of low cost and high corrosion resistance; can improve the electrical properties of glass, especially the dielectric properties, and improve the mechanical properties, water resistance and acid resistance of the glass fiber; and can significantly reduce the raw material cost, significantly reduce the volatilization of the raw material, and reduce the corrosion of the refractory material; and is suitable for large-scale tank furnace production.
