Problems solved by technology

[0002] High-aluminum wear-resistant plastic is a kind of amorphous refractory material with high plasticity in a long period of time and is in the form of hard mud paste. It belongs to high-alumina plastic and is used for some low-temperature kiln masonry or repair boilers. Or when heating the lining of the furnace, the traditional high-alumina refractory plastic hardens for a long time, which is inconvenient for construction, especially in emergency repairs, when the time is limited

Abstract

The invention relates to a high temperature resistant material, specifically to high-strength refractory plastics, which is composed of the following raw materials (by weight): 15-25 parts of high-alumina bauxite with particle size being 0.02-0.03 mm, 7-10 parts of aluminium oxide with particle size being 0.3-0.71 mm, 7-13 parts of aluminium oxide with particle size being 2-3 mm, 12-25 parts of aluminium oxide with particle size being 3-5 mm, 5-15 parts of aluminium oxide with particle size being 5-8 mm, 7-10 parts of silica micropowder with particle size being 0.05-0.15 mm, 15-20 parts of silica micropowder with particle size being 0.5-1 mm, 8-15 parts of magnesia, 25-30 parts of mullite and 13-20 parts of aluminium dihydrogen phosphate. The high-strength refractory plastics provided by the invention has short hardening time, is convenient for construction, and is used for repairing parts inside a furnace which are severely worn and scoured.

Description

technical field [0001] The invention relates to a high-temperature-resistant material, in particular to a high-alumina refractory plastic. Background technique [0002] High-aluminum wear-resistant plastic is a kind of amorphous refractory material with high plasticity in a long period of time and is in the form of hard mud paste. It belongs to high-alumina plastic and is used for some low-temperature kiln masonry or repair boilers. Or when heating the lining of the furnace, the traditional high-aluminum refractory plastic hardens for a long time, which is inconvenient for construction, especially in emergency repairs, and the time is limited. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a high-temperature wear-resistant plastic with short hardening time and a preparation method thereof. [0004] The specific technical solutions are: [0005] High-strength refractory plastic, composed of the following r...
