Novel high-strength glass fiber

Abstract

The invention provides a novel high-strength glass fiber which comprises the following components in parts by weight: 55-65 parts of SiO2, 15-25 parts of Al2O3, 5-10 parts of CaO, 5-10 parts of MgO, 0.05-0.1 part of K2O, 0.05-0.1 part of Na2O, 0.05-0.1 part of B2O3, 0.05-0.1 part of Li2CO3, 0.05-0.1 part of CeO2, 0.05-0.1 part of Fe2O3, 0.05-0.1 part of WO3, 0.05-0.1 part of TiO2, 0.05-0.1 part of MnO2 and 0.05-0.1 part of ZrO2. The novel high-strength glass fiber has the technical effects that a few bubbles are generated and both the acid resistance and the high temperature resistance are greatly improved.

Description

technical field [0001] The invention relates to a novel high-strength glass fiber, which belongs to the technical field of chemical industry. Background technique [0002] Compared with ordinary non-alkali glass fiber, high-strength glass fiber has high tensile strength, high elastic modulus, good impact resistance, good chemical stability, good fatigue resistance, high temperature resistance and other excellent properties, and is widely used in aerospace, aviation, etc. , weapons, ships, chemical industry and other fields, such as missile engine shells, aerospace aircraft linings, gun stocks, launching barrels, bulletproof armor, high-pressure vessels, etc. With the development of science and technology, the demand for high-strength glass fibers in optical cables, heat-resistant materials, friction materials and other industrial fields is also expanding. [0003] Existing high-strength glass fibers have some shortcomings, such as a large number of bubbles, insufficie...
