Abstract

The invention relates to a fire-resistant material and particularly relates to a high-temperature wear-resistant coating. The high-temperature wear-resistant coating is prepared from the following raw materials: 13-22 parts of white corundum micro-powder, 6-11 parts of cement, 4-14 parts of carbon fluoride, 8-13 parts of titanium dioxide, 9-14 parts of Mohr's salt, 5-7 parts of barium sulfate, 3-9 parts of magnesium hexasilicate, 4-9 parts of aluminum triphosphate, 2.3-4.5 parts of sodium persulfate, 0.7-1.3 parts of PA-80 cement gum, 6-8 parts of aluminium oxide, 0.3-1.5 parts of silica micro-powder and 3-5 parts of phosphoric acid. The high-temperature wear-resistant coating provided by the invention has the advantages of very good mechanical property and shock resistance, high temperature resistance and excellent adhesive force and can resist wear and hardly fall off when used in a high-temperature furnace.

Description

technical field [0001] The invention relates to a refractory material, in particular to a high-temperature wear-resistant coating. Background technique [0002] High-temperature wear-resistant coatings are mainly used in furnace bodies in the fields of metallurgy, power generation, fluidized beds, building materials, and waste incineration. The high-temperature wear-resistant coating prepared by the existing technology is lacking in wear resistance and mechanical properties, and is prone to cracks and peeling off in high-temperature use environments. Contents of the invention [0003] In view of the above technical problems, the present invention provides a high temperature resistant coating with good wear resistance and mechanical properties. [0004] The specific technical solutions are: [0005] The high-temperature wear-resistant coating is prepared from the following raw materials: 13-22 parts by weight of white corundum powder, 6-11 parts of cement, 4-14 parts of c...
