Abstract

The invention discloses a wide-temperature-range high-infrared-emissivity coating material and a preparation method thereof. The wide-temperature-range high-infrared-emissivity coating material is prepared by mixing wide-temperature-range high-infrared-emissivity powder and an adhesive in a weight ratio of 1:1-1:2.5. The wide-temperature-range high-infrared-emissivity powder is prepared from the following raw materials in percentage by weight: 5-30% of iron-ore-slag-base high-emissivity powder material, 25-50% of hercynite, 0-15% of magnetite, 0-20% of zirconium oxide, 20-40% of cerium oxide and 0-15% of molybdenum silicide. The adhesive is aluminum oxide sol. The wide-temperature-range high-infrared-emissivity coating material can be used on an aluminum oxide fiber refractory material surface, can be used at higher temperature, and has the high-infrared-emissivity energy-saving function and the surface reinforcement function.

Description

technical field

[0001] The invention relates to an energy-saving coating material for a high-temperature furnace, in particular to an infrared high-emissivity coating material with a wide temperature range and a preparation method thereof. Background technique

[0002] High-temperature kilns are widely used in various fields of national production and scientific research. They are high-energy-consuming industrial products and account for a large share of total energy consumption. In particular, the thermal energy utilization rate of most industrial high-temperature furnaces is generally low, and there is a lot of room for energy saving. Coating the inner wall of a high-temperature furnace with high-emissivity materials is an effective way to achieve energy saving. High-emissivity coatings can not only increase the emissivity of the inner wall of the furnace, improve the distribution of heat rays in the furnace, increase the utilization of secondary emission heat energy, and ...
