Abstract

The invention relates to a preparation method of high-performance glass fiber yarn. The high-performance glass fiber yarn is prepared from, by weight, 0-40% of waste glass, 0-40% of silica sand, 3-7%of fluorite, 10-16% of pyrophyllite, 8-12% of kaoline, 4-8% of dickite, 4-8% of calciclase, 5-11% of sodium borate, 1-3% of limestone, 2-6% of marble, 5-9% of dolomite, 1-3% of fluorite and 2-4% of mirabilite. Crushing, smelting, wiredrawing, drying, yarn manufacturing and other technologies are adopted, and the high-quality glass fiber yarn is produced. According to the produced high-performanceglass fiber yarn, effective use of waste resources is enhanced, and environmental pollution is lowered; the produced glass fiber yarn has the advantages of being high in acid and alkali resistance, high in mechanical strength, good in rigidity and resistant to aging.

Description

technical field [0001] The invention relates to a glass fiber, in particular to a preparation method of a high-performance glass fiber yarn. Background technique [0002] Glass fiber is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, equivalent to a hair 1 / 20-1 / 5 of silk, each bundle of fiber precursors consists of hundreds or even thousands of single filaments. Glass fiber has the characteristics of good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Usually used as reinforcing material of composite material, electrical insulation and heat insulation materials, circuit substrate and other national economy fields. [0003] Glass fiber, its main components are silica, alumina, calcium oxide, boron oxide, magnesium o...
