Abstract

The invention discloses a refractory material with heat insulation and heat preservation as well as a preparation method thereof. The refractory material with heat insulation and heat preservation is prepared by the following raw materials: aluminum oxide, silicon oxide, magnesium carbonate, calcium oxide, titanium oxide, zirconium oxide, zinc oxide, water, sodium bicarbonate, a pore forming agent and the like. The pore forming agent comprises sucrose, carbon powder, aluminium powder, polyethylene microspheres, diatomite, copper sulfate pentahydrate, potassium dodecylbenzenesulphonate, water and the like. The refractory material with heat insulation and heat preservation is prepared by the following steps: pretreatment of raw materials, mixing of raw materials, steam curing, cutting and sintering, aftertreatment, and the like. The light type refractory material has the advantages of lower volume density and higher porosity, high available temperature and high compression strength, lower thermal conductivity, and good heat insulation effects.

Description

technical field [0001] The invention relates to the technical field of refractory manufacturing, in particular to a thermal insulation refractory and a preparation method thereof. Background technique [0002] In the traditional sense, refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 °C. And parts of the material, and can withstand the corresponding physical and chemical changes and mechanical action. [0003] Most refractory materials are made of natural ores (such as refractory clay, silica, magnesite, dolomite), and some industrial raw materials and synthetic raw materials (such as industrial alumina, silicon carbide, synthetic mullite, Synthetic spinel, etc.) are also increasing, so there are many types of refractory materials. According to the mineral composition, refractories can be divided into silica, aluminum silicate, magnesia, dolomite, olivine, spinel, carbonaceous, zirconium-containing refractories and ...
