Abstract
A composition for preparing high-performance glass fiber by tank furnace production comprising in preferred percentage by weight: 57.5˜62.5% of SiO2, 14.5˜17.5% of Al2O3, 13.5˜17.5% of CaO, 6.5˜8.5% of MgO, 0.05˜0.6% of Li2O, 0.1˜2% of B2O3, 0.1˜2% of TiO2, 0.1˜2% of Na2O, 0.1˜1% of K2O and 0.1˜1% of Fe2O3 and (CaO+MgO)/MgO>3, with the content of at least one of the three components, A2O, B2O3 and TlO2 higher than 0.5%, with the composition yielding glass fiber having improved mechanical property, causing the melting and clarification of glass and forming performance of fiber close to those of boron-free E glass, and facilitating industrial mass production by tank furnace processes with manufacturing costs close to those of conventional E glass.
