Abstract

The invention discloses an alkali-free glass fiber, which comprises wollastonite: 200-300 parts; pyrophyllite 250-350 parts; quicklime 50-100 parts; kaolin 100-200 parts; dolomite 50-100 parts; 10-80 parts of boronite; 80-160 parts of leucaoite; 10-30 parts of fluorite; 5-20 parts of Glauber's salt. The formula disclosed in the invention innovatively uses wollastonite as a raw material for producing alkali-free fiber glass, reduces the usage of pyrophyllite and quicklime, saves raw material costs and energy costs, and has good economic benefits.

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...
