Problems solved by technology

[0005] However, the amount of binder used in the raw material of the above-mentioned patented ceramic fiber is relatively large (2-6%). Even if the binder has high temperature resistance, it still partially decomposes in a high temperature environment, thereby leaving pores inside the ceramic fiber, resulting in The density of ceramic fibers is reduced, which ultimately affects the strength of the product

Abstract

The invention relates to the field of refractory materials, and discloses a high-density refractory ceramic fiber and a preparation method thereof. The ceramic fiber is prepared by mixing an A ceramicslurry and a B ceramic slurry, wherein the A ceramic slurry comprises electrofused chromium oxide, zirconia, alumina micro powder, yttrium oxide micro powder, lanthanum and / or lanthanide metal oxidemicro powder, metal yttrium micro powder, tetradecyl trimethyl ammonium bromide, ethanol and water; and the B ceramic slurry comprises electrofused chromium oxide, zirconia, alumina micro powder, yttrium oxide micro powder, lanthanum and / or lanthanide metal oxide micro powder, metal yttrium micro powder, sodium dodecyl benzene sulfonate, binding agent, ethanol and water. According to the high-density refractory ceramic fiber, the using amount of the binding agent is greatly reduced, and the density of the ceramic fiber is effectively increased, therefore, the ceramic fiber has a higher strength.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a high-density refractory ceramic fiber and a preparation method thereof. Background technique [0002] Ceramic fiber is a kind of fibrous lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance, so it is widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, Glass, electronics and other industries have been widely used. [0003] At present, the widely used high-temperature insulation fiber materials mainly include aluminum silicate-based ceramic fibers, alumina-based and zirconia-based ceramic fibers. However, aluminum silicate refractory fiber products are considered carcinogenic and banned. Although zirconia-based ceramic fibers can withstand high temperatures of 2000°C, they will expand in volume, ...
