Composition for high-performance heat-resistant and corrosion-resistant glass fibers

Abstract

The invention provides a composition for high-property heat-resisting corrosion-resisting glass fiber. The composition comprises the following components: 55-63wt% of SiO2, 18-23wt% of Al2O3, 8-16wt% of MgO, 7-13wt% of CaO, 0-1wt% of CeO2, 0-0.5wt% of Li2O, 0-0.4wt% of Fe2O3, 0-2wt% of TiO2, 0-0.5wt% of WO3 and 0-1.5wt% of Bi2O3, wherein the total content of SiO2, Al2O3, MgO and CaO is 94-98wt%; and CeO2, Li2O, Fe2O3, TiO2, WO3 and Bi2O3 are modifiers, the content of a single modifier is 0 at different times, and the total content of the modifiers is 2-6wt%. According to the invention, raw materials are adopted to produce the high-property heat-resisting corrosion-resisting glass fiber, thus the production difficulty is low, and the cost is low; and the produced glass fiber can be used as a reinforcing material and a heat-resisting heat-insulating material of a resin-based composite material and has the characteristics of high strength, corrosion resistance, high temperature resistance and light mass.
