Abstract

The invention discloses an alkali-free glass fiber. The alkali-free glass fiber is prepared from 200-300 parts of wollastonite, 250-350 parts of pyrophyllite, 50-100 parts of quick lime, 100-200 parts of kaolin, 50-100 parts of dolomite, 10-80 parts of colemanite, 80-160 parts of quartzitic sandstone, 10-30 parts of fluorite and 5-20 parts of mirabilite. According to the prescription disclosed by the invention, the wollastonite is creatively used as a raw material for producing the alkali-free glass fiber, so that the amount of used pyrophyllite and quick lime is reduced, the raw material cost and energy cost are lowered, and a good economic benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of glass fiber preparation, in particular to an alkali-free glass fiber and a preparation method thereof. Background technique [0002] At present, my country's glass fiber industry mainly adopts the pool kiln wire drawing production process. When this process is used to produce alkali-free glass fiber, the main mineral powder (micro powder) raw material is pyrophyllite. With the expansion of global pool kiln glass fiber production capacity, mineral powder Raw material resources will continue to shrink. At the same time, the main component of wollastonite is CaSiO3 or CaSiO2, which is very close to the chemical composition of alkali-free glass fiber, and has a low melting point, which is helpful for melting. China is the country with the richest wollastonite resources in the world. my country's wollastonite has been widely used in papermaking, ceramics, cement and other industries, but it has not yet matured...
