Abstract

An alkali-resistant heat-resistant glass fiber is provided. The glass fiber is characterized by comprising, by mass, 48-65 parts of SiO2, 22-30 parts of Al2O3, 23-35 parts of CaO, 3.5-6 parts of CaF2, 2.5-6.8 parts of CaWO4, 0.5-3.5 parts of TiO2, 0.2-1.7 parts of MgO, and 1-5.5 parts of FeCr2O4. The glass fiber has a flat and smooth appearance, even color and high mechanical strength. A preparing process is simple. The glass fiber prepared by a corporation has good alkali resistance, and can be widely applied in the fields of precision meter thermal protection member manufacturing, ablative material manufacturing, heat insulation material manufacturing, and the like.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an alkali-resistant and heat-resistant glass fiber and a preparation method thereof. Background technique [0002] Glass fiber has a wide range of uses in transportation, industry, construction, environment and other fields. With the increasing expansion of the field of glass fiber, the current mechanical properties of alkali-free glass fiber are far from being able to meet the needs of light military weapons and aviation components. , special-purpose automotive components, and wind power generation. According to market demand, it is necessary to seek suitable glass fibers with higher strength, corrosion resistance and high temperature resistance, good light weight. Contents of the invention [0003] In order to solve the above existing problems, the object of the present invention is to provide an alkali-resistant and heat-resistant glass fiber. The alkali-resistant an...
