Abstract

The invention provides a special-shaped glass fiber and a preparation method thereof. The special-shaped glass fiber comprises the following components in percentage by mole: 52-58% of SiO2, 16-24% of B2O3, 13-19% of Al2O3, 1-5% of CaO, 4.2-8% of MgO, 0.4-2% of F2, 0-0.5% of Li2O, 0-0.4% of Fe2O3, 0-0.2% of K2O and 0-0.2% of Na2O. Compared with the prior art, the special-shaped glass fiber with a relatively-low dielectric constant and dielectric loss factor is prepared by controlling components in a formula and the contents of all the components, and meanwhile, the special-shaped glass fiber has relatively-high mechanical property, filling rate and special-shaped rate. Experiment results prove that the special-shaped glass fiber provided by the invention has the dielectric constant of smaller than 4.7 and the dielectric loss factor of smaller than 10<-3>.

Description

technical field [0001] The invention relates to the technical field of glass fibers, and more specifically relates to a special-shaped glass fiber and a preparation method thereof. Background technique [0002] Special-shaped glass fiber, also known as special-shaped cross-section glass fiber, is a glass fiber with a special cross-sectional shape spun through a certain geometric shape of the spinneret hole. Since the cross-section of special-shaped glass fibers can form irregular geometric shapes, it has better optical effects and larger specific surface area compared with traditional glass fibers, and can solve the problem of small reflectivity and refractive index of glass fibers to light. , The problem of slow optical signal transmission speed has huge application potential in the rapidly developing field of electronic information industry. [0003] At present, special-shaped glass fibers are mostly made of ordinary non-alkali glass as raw materials, and are melted and f...
