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