High-temperature-resistant cement and preparation method for same

Abstract

The invention provides high-temperature-resistant cement and a preparation method for the same. The high-temperature-resistant cement comprises 20 to 40 parts by weight of light mullite brick powder, 15 to 35 parts by weight of high-temperature alumina, 5 to 15 parts by weight of superfine alumina powder, 5 to 15 parts by weight of sillimanite powder, 1 to 8 parts by weight of calcium bentonite, 10 to 25 parts by weight of refractory clay, 2 to 10 parts by weight of polycrystal mullite fiber and 22 to 48 parts by weight of a binding agent. Compared with the prior art, the high-temperature-resistant cement has the advantages that by adding the polycrystal mullite fiber into the high-temperature-resistant cement, the high temperature resistance and heat shock resistance of a product can be improved, and adverse impacts on a kiln caused by shrinkage of the high-temperature-resistant cement and cracking under quick cooling and heating conditions can be effectively prevented; the content of the alumina in the high-temperature-resistant cement is high, different grain diameters are matched with one another, and mullite phases and a small number of corundum phases with excellent performances are generated under high-temperature conditions favorably, thereby improving the high temperature resistance.

AI Technical Summary

Benefits of technology

This patented technology describes an improved type of ceramic material that has better properties at extreme temperatures than traditional materials like silicate bricks or quartz glass due to its ability to maintain strength even when exposed during use for longer periods of time without losing some degree of shape overtime. It includes special ingredients such as lime sand (CaO), bauxite flour, feldspathierite, zircon crystal fibers, magnesium oxide, tungsten carbide, borosilicate acid salt, and bind agents. These added components help improve durability while still being able to perform their function properly despite experiencing sudden changes in environmental factors like hot weather or low humidity levels.

Problems solved by technology

This patented technical describes how heavy weight ceramics like zircon tend to break easily when exposed at higher temperatures than usual due to their lower melting point compared to normal porcelain blocks. To solve this issue, researchers developed various methods called fused linings containing special types of fillers - calcium oxide, talc, quartz sand, sintered dolanolithic stones, and mixtures thereoverages. These compositions help prevent damage from stress caused by these elements while maintaining strength properties over time under extreme conditions found within large industries like steel manufacturing processes.
