Abstract

The invention discloses a new type of glass fiber, which relates to the technical field of new materials. The glass fiber is mainly composed of SiO2, Al2O3 and CaO raw materials, and on this basis, MgO, ZrO2, TiO2, Fe2O3, Na2O, K2O and Li2O and other components are introduced. The manufacturing process includes raw material mixing and melting, acid leaching, water cleaning, heat treatment, post-surface treatment, etc. The glass fiber prepared by the above process has high silica content, smooth appearance and uniform color, which can be well applied to Various post-processing manufacturing processes, excellent high temperature resistance, can be used for a long time below 1100°C, has good ablation performance, better high temperature resistance, chemical corrosion resistance and elastic modulus, and can be widely used in the manufacture of precision instruments Heat protection parts, ablation materials, thermal insulation materials and other fields.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a novel glass fiber. Background technique [0002] With the continuous development of the economy, the demand for glass fiber in industrial smelting, welding and other industries has increased sharply. At present, some alkali-free glass fibers are used, which have a very short life and poor heat insulation. Damaged, thereby endangering personal safety, its acid and alkali resistance, rigidity, anti-aging, high temperature resistance properties need to be improved. Glass fiber is an inorganic non-metallic material, which has many advantages such as good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, so it has become the most widely used type of matrix material in reinforced composite materials. With the wide application of inorganic non-metallic materials, the industry's requirements for glass fibers are also increasing. As a r...
