High-temperature refractory mortar

Abstract

The invention relates to a refractory material, particularly a high-temperature refractory mortar which is prepared from the following raw materials in parts by weight: 20-35 parts of 1.5-2.5mm quartz, 20-35 parts of 2-5mm kaolin, 5-10 parts of 0.5-1.5mm smolmitza, 2-4 parts of 0.05-0.15mm yttrium oxide, 10-15 parts of water glass, 5-10 parts of 1-1.5mm copper oxide and 2-4 parts of high-alumina cement. The high-temperature refractory mortar provided by the invention has favorable stripping resistance and seismic stability, and prolongs the service life of the kiln.

Description

technical field [0001] The invention relates to a refractory material, in particular to high-temperature refractory mortar. Background technique [0002] Refractory mortar is mainly made of high-quality refractory powder, high-strength and temperature-resistant chemical binders and additives. It is suitable for kiln masonry that requires small mortar joints, good sealing, and high bonding strength. The currently used cement has poor peeling resistance and poor seismic stability. Contents of the invention [0003] In view of the above technical problems, the present invention provides a cement with strong anti-stripping performance and high seismic stability. [0004] The specific technical solutions are: [0005] High-temperature refractory cement is composed of raw materials in parts by weight: 1.5-2.5mm quartz 20-35 parts, 2-5mm kaolin 20-35 parts, 0.5-1.5mm black clay 5-10 parts, 0.05-0.15mm yttrium oxide 2- 4 parts, 10-15 parts of water glass, 5-10 parts of 1-1.5mm ...
