Embodiment 1

[0012] A glass fiber consisting of the following components by weight: SiO 2 61.0, Al 2 o 3 18.4, CaO 7.0, MgO 11.0, ZnO 0.7, TiO 1.3, Fe 2 o 3 is 0.6, Li 2 O is 1.0, B 2 o 3 is 3.3.

[0013] The preparation method of the above-mentioned embodiment: mix various raw materials uniformly and put them into a tank kiln, and after melting, clarification, and homogenization, a glass liquid is obtained, and the glass liquid is cooled, flowed out, and drawn to obtain glass fibers.

[0014] Based on the above, the present invention improves the mechanical strength, chemical stability and thermal stability of glass fibers by adding SiO2 and controlling its content; controlling the content of Al2O3 effectively reduces the tendency of glass devitrification and improves the mechanical strength of glass fibers. performance; and by controlling the total amount and mutual ratio of CaO and MgO, the high-temperature viscosity of the glass is reduced and its crystallization strength is imp...

Abstract

The invention discloses a glass fiber and relates to the technical field of inorganic non-metallic materials. The glass fiber comprises, by weight, 60.0-64.0 parts of SiO2, 14.3-22.0 parts of Al2O3, 5.0-8.0 parts of CaO, 9.0-12.0 parts of MgO, 0.1-2.0 parts of ZnO, 0.5-1.6 parts of TiO, 0.3-0.9 parts of Fe2O3, 0.2-1.1 parts of Li2O and 0.6-4.3 parts of B2O3. Through optimization of a ratio of the above components, the prepared glass fiber has large curing mechanical strength, good chemical stability and good heat stability.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a glass fiber. Background technique [0002] 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 reinforcing material, the mechanical properties of glass fiber need to be more excellent to meet the demanding requirements of automobiles, high-pressure vessels, large wind turbine blades and other fields; at the same time, for mass application, glass fiber must maintain reasonable production difficulty and production cost. Therefore, improving the mechanical properties and formability of glass fibers h...
