Abstract

The invention relates to a method for preparing industrial waste alkali-resistant glass fibers modified with intermediate oxides. The method is characterized in that the mass percentage of mixed industrial wastes is 26-39%, a ratio of red mud to blast furnace slag is 1:(2.1-3), the industrial wastes are modified with the intermediate oxides iron oxide and alumina, and the raw material is sequentially pretreated, mixed, melted and drawn to finally prepare the glass fibers with a high industrial waste proportion and a good alkali resistance. The method changes the wastes into valuables, improvesthe application values of the red mud and blast furnace slag, reduces the environmental hazard brought by massive accumulation of wastes, and achieves the dual development of economy and environmental protection.

Description

technical field [0001] The invention relates to a method for preparing alkali-resistant glass fiber, especially a method for preparing alkali-resistant glass fiber from industrial waste modified by intermediate oxides. The glass fiber is provided by industrial waste red mud and blast furnace slag. The intermediate oxide improves the alkali resistance, and the purpose is to use a large amount of industrial waste as much as possible under the premise of improving the alkali resistance of the glass fiber, turn waste into treasure, and prepare glass fiber with excellent corrosion resistance. Background technique [0002] Blast furnace slag is industrial waste slag produced during the pig iron smelting process. It is generally formed by gangue, ash, flux and other impurities that cannot enter pig iron. The main components are silicate and aluminate. In the process of ironmaking, 300-360kg of pig iron will be produced for every ton of pig iron. The main component is SiO 2 、Al 2 ...
