Abstract

The invention relates to the technical field of glass fiber preparation, in particular to a high-strength and high-modulus glass fiber composition, each raw material including SiO 2 、Al 2 o 3 , Fe 2 o 3 , CaO, MgO, TiO 2 、K 2 O, BeO, CeO 2 etc.; the production process includes pretreatment, glass fiber precursor preparation, pickling, warm water rinsing, and heat setting steps; the present invention introduces an appropriate amount of rare earth elements, and rare earth oxides can not only reduce the melting temperature and high temperature viscosity of the glass, but also improve the viscosity of the glass. The mechanical properties, modulus and strength are improved; through the ternary mixed alkaline earth effect of CaO, MgO and rare earth elements, on the basis of ensuring that the glass fiber has high mechanical properties and low molding temperature, the liquidus temperature of traditional high-performance glass is solved If it is too high, the crystallization rate is too fast, and glass crystallization is prone to occur.

Description

technical field [0001] The invention relates to the technical field of glass fiber preparation, in particular to a high-strength and high-modulus glass fiber composition. Background technique [0002] High-strength glass fiber is the most widely used type of glass fiber with special functions. It has excellent properties such as high strength, high temperature resistance, impact resistance, high wave penetration, and corrosion resistance. It is widely used in aerospace, aviation, weapons, ships, and chemical industries. Applications, such as missile engine casings, aerospace aircraft linings, composite gun stocks, launching barrels, high-pressure vessels, sucker rods, bulletproof armor, etc. With the promotion and application of high-strength glass fibers in industrial fields such as pressure vessels, optical cables, heat-resistant materials, and friction materials, the demand for them is also expanding. Chinese patent CN105174732A discloses a high-strength glass fiber and ...
