Problems solved by technology

The glass fiber significantly reduces the B 2 o 3 and F 2 content, but at the same time in order to improve the fiber-forming performance, the formula also added expensive CeO 2 , SrO and MnO 2 , which will obviously greatly increase the production cost of glass fiber

Abstract

The invention discloses an organic or inorganic fiberglass for enhancement, and a composition thereof. The fiberglass is characterized in that the fiberglass comprises the following components, by weight, 56-61 parts of SiO2, 12-16 parts of Al2O3, 18-22 parts of CaO, 3.5-6 parts of MgO, 23-27 parts of CaO+MgO, 0.2-0.5 parts of TiO2, 0.8 or less of Na2O+K2O, and 0.5 or less of Fe2O3. Boron or fluorine contained raw materials are not specially added to glass fiber products of the invention, so the cost is saved, and the discharge of harmful exhaust gases is substantially reduced; the tensile strength, the elastic modulus, the corrosion resistance and the high temperature resistance of the products are substantially higher than that of traditional E glass fibers, so the products can be applied to fields of automobiles, wind blades, compressed gas cylinders and the like; and the products which have good fiber forming properties allows the large scale production to be economically realized.

Description

Technical field: [0001] The invention relates to a glass fiber, in particular to a boron-free and fluorine-free reinforcing glass fiber composition, which belongs to the technical field of glass fiber materials. Background technique: [0002] Glass fiber belongs to inorganic non-metallic materials. It has many advantages such as good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is currently the most widely used type of matrix material in reinforced composite materials. [0003] The glass component used to make continuous glass fibers is currently mainly E glass, which accounts for almost 99% of the total glass fiber production. Traditional E-glass fiber belongs to SiO 2 -Al 2 o 3 -B 2 o 3 -CaO system glass, this kind of glass has good electrical and mechanical properties, and has relatively low molding temperature and wide operating temperature range, and good processing performance, so it has become the most widely used...
