High-temperature-resistant heat-insulating ash material for coke oven smoke guide hole cover and preparation method of high-temperature-resistant heat-insulating ash material
The invention relates to a high-temperature-resistant heat-insulating ash material for a smoke guide hole cover of a coke oven and a preparation method of the high-temperature-resistant heat-insulating ash material, and the problems of serious heat loss and low heat utilization rate of the traditional smoke guide hole cover can be effectively solved. The high-temperature-resistant heat-insulating ash material is prepared from the following raw materials in parts by weight: 15 to 30 parts of polyethylene resin, 25 to 30 parts of silicon dioxide aerogel, 15 to 20 parts of silicon carbide, 10 to 15 parts of aluminum oxide, 10 to 15 parts of an adhesive, 1 to 5 parts of indium oxide, 0.5 to 3 parts of a thickening agent, 0.25 to 0.5 part of a dispersing agent, 0.01 to 0.8 part of a mildew preventive, 0.02 to 1.5 parts of a defoaming agent and 0.01 to 1 part of an anti-settling agent. The material can resist high temperature up to 1300 DEG C, the lowest heat conductivity at the high temperature can reach 0.03 w/m.k, the surface temperature of the smoke guide hole cover can be reduced to about 240 DEG C through application of the high-temperature-resistant heat insulation material, the temperature is reduced by about 30% compared with a traditional smoke guide hole cover without the heat insulation material, the working environment of a coke oven top is improved, the service life of the smoke guide hole cover is prolonged, and the heat utilization rate is increased; and the high-temperature-resistant heat-insulating ash material is an innovation of high-temperature-resistant heat-insulating mortar.
