Abstract

The invention belongs to the technical field of refractory materials and particularly discloses wear-resistant aluminum silicate refractory fibers. The wear-resistant aluminum silicate refractory fibers are prepared by, by weight, 100-120 parts of flint clay powder, 55-65 parts of aluminum oxide, 30-40 parts of silicon dioxide, 32-36 parts of silicon nitride, 20-25 parts of ABS resin, 18-22 parts of polyurethane, 10-15 parts of natural rubber, 1-2 parts of carbon black, 2-3 parts of zirconate coupling agent, 0.6-0.8 part of dicumyl peroxide, 16-20 parts of silicon dioxide aerogel, 0.2-0.6 part of dispersing agent, 15-25 parts of borax and 20-25 parts of refractory impregnation liquid. The wear-resistant aluminum silicate refractory fibers are high in friction resistance and impact resistance, resistant to the impact and abrasion of hot slag and hot waste residues, resistant to environment stress, high in aging resistance, capable of being used for a long time under high temperature and long in service life.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a wear-resistant aluminum silicate refractory fiber. Background technique [0002] Refractory fiber is a fibrous heat-insulating refractory material, which has the characteristics of general fibers and can be processed into various paper, thread, rope, blanket and felt products. At the same time, it has high temperature resistance and corrosion resistance that ordinary fibers do not have. Widely used in metallurgy, chemical industry, machinery, building materials and other industries. At the same time, refractory fiber also has good thermal capacity and infrared heating effect, which can effectively save energy and is an ideal energy-saving and efficiency-enhancing material. Among them, the aluminum silicate refractory fiber is made of high-quality coke gemstones and high-purity alumina as raw materials. After proper process treatment, it is melt-blown o...
