Title:
LOW DIELECTRIC GLASS FIBER AND PREPARATION METHOD THEREFOR, GLASS FIBER PRODUCT, COMPOSITE MATERIAL AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/105185
Kind Code:
A1
Abstract:
Provided are low dielectric glass fiber and a preparation method therefor, a glass fiber product, a composite material and an application thereof. A low-dielectric glass having excellent comprehensive properties such as high mechanical strength, good dielectric properties and a simple melting process can be obtained by reasonably adjusting the proportions of oxides in a glass composition. Specifically, by reasonably configuring a ratio of silicon oxide, aluminum oxide and boron oxide, the glass fiber has a relatively low dielectric constant and dielectric loss, and the glass viscosity is suitably adjusted; meanwhile, with consideration to dielectric properties and mechanical strength, by appropriately setting the amounts of alkaline earth metal oxides, alkali metal oxides, TiO2, CeO2 and SnO2, the melting and clarifying properties of the glass are further improved, the drawing and forming temperature is lower, the stability and yield is higher, the density is lower, and excellent working performance is achieved.
