Title:
LOW DIELECTRIC MODIFIED GLASS FIBER, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/011207
Kind Code:
A1
Abstract:
The present application relates to a low dielectric modified glass fiber, and a preparation method therefor and an application thereof. The low dielectric modified glass fiber contains components such as: one or two of SiO2, Al2O3, B2O3, R2O, MgO and CaO; TiO2; ZnO; and a functional oxide. The functional oxide is a mixture of CeO2, La2O3, Nd2O3 and Y2O3. According to the low dielectric modified glass fiber provided in the preparation application, the functional oxide of specific composition is added and a usage amount relationship between the functional oxide and SiO2 is regulated, such that a dielectric constant can be significantly reduced, and the low dielectric modified glass fiber can be widely applied to a printed circuit board.
