Fireproof material filler and preparation method therefor

Abstract

The invention relates to fireproof material filler and a preparation method therefore. The fireproof material filler is composed of nano aluminum oxide, nano silicon dioxide, nano zirconium oxide, nano zinc oxide, erbium oxide, cerium oxide and maltodextrin. The filler provided by the invention can be used for improving the thermal shock resistance of the fireproof material, is strong in oxidization resistance, slag resistance and alkali metal corrosion resistance, is excellent in scouring resistance, heat isolation and insulation and is good in high-temperature volume stability; the filler can be highly and uniformly dispersed inside to promote sintering and has more uniform organization structures, so that the strength and thermal shock resistance of a product are improved.

Description

technical field [0001] The invention relates to a refractory filler with improved firing quality, increased strength, good thermal conductivity and excellent thermal shock resistance and a preparation method thereof. Background technique [0002] With the increasing shortage of energy, countries are paying more and more attention to the development, production and use of high-temperature industrial energy-saving materials. High-temperature kilns need to use a large number of refractory materials with excellent performance or special properties. For example, in order to prolong the service life and improve the heat exchange capacity, the glass kiln regenerator needs to have excellent corrosion resistance, creep resistance and lattice body with special shape and size. In addition, the upper structure of the oxy-fuel glass melting furnace also needs to use concave refractory materials with good corrosion resistance and creep resistance and filled with insulating materials.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing refractory materials have insufficient thermal shock resistance and high temperature toughness, so in the kiln of rapid firing, rapid cooling and rapid heating, it is easy to break at the weak part, especially at the shrinkage joint position, or the corner edge To provide a refractory filler that improves the firing quality, improves the strength, has good thermal conductivity, and has excellent thermal shock resistance due to the defects of partial fracture.
