Method for preparing infrared coating paint from metallurgical solid waste

Abstract

The invention discloses a method for preparing infrared coating paint by utilizing metallurgical solid waste, and belongs to the field of infrared energy-saving materials. The method for preparing infrared coating paint by using metallurgical solid waste includes the following steps: a. Mixing the metallurgical solid waste and iron oxide red evenly; b. sintering the mixture in stages, and cooling to obtain a calcined material; c. Mix evenly with the transition metal oxide; d. The mixture is sintered again, cooled, and mechanically crushed to obtain infrared coating powder; e. After fully mixing the infrared coating powder, high-temperature binder and water, an infrared coating is obtained. layer of paint. The material prepared by the method of the invention has a softening temperature of not lower than 1500° C., good high-temperature adhesion, a comprehensive emissivity of not less than 0.87, a low-band emissivity (1-5 μm) of not less than 0.93, and excellent comprehensive performance. , the production cost is low, and the problems of poor radiation performance and high preparation cost of the infrared coating paint under the existing high temperature conditions can be effectively solved.

Description

technical field [0001] The invention belongs to the field of infrared energy-saving materials, and relates to a method for preparing infrared coating paint by utilizing metallurgical solid waste. Background technique [0002] In recent years, infrared coating coatings have made great progress in aviation, construction, photocatalysis, energy saving and environmental protection and other fields, especially the application of infrared coating coatings in the field of energy saving and environmental protection is the main development trend of infrared coating coatings. However, compared with foreign coatings, there is a huge gap in product performance between my country's infrared coatings and foreign coatings. The utilization rate of infrared coatings in many developed countries has reached 40%, and the emissivity is above 0.9, while the utilization rate of infrared coatings in industrial furnaces in my country is only 15%, and the infrared emissivity is also around 0.8, which...
