Problems solved by technology

[0003] Chinese patent number: CN1552779A discloses a high-temperature far-infrared coating. The coating is prepared from micro-nano ultrafine powder. The coating has good suspension and stability and can be stored for a long time. Then it is applied to the inner wall of the furnace lining, which will easily lead to an increase in the thermal conductivity of the furnace lining matrix. Large, resulting in increased heat dissipation of the furnace body, resulting in energy loss
Patent CN101113097A uses lightweight floating beads as a foaming agent to sinter porous ceramics with low thermal conductivity, but the preparation method is relatively complicated, and the stability of the materials after mixing is poor, and the coating is difficult to preserve for a long time.

Description

technical field [0001] The invention relates to a far-infrared energy-saving coating and a preparation method thereof, which belongs to the technical field of coatings and is mainly applicable to industries such as high-temperature kilns, steam boilers, fuel vehicles, and ships, and achieves the purpose of energy conservation and environmental protection. Background technique [0002] Far-infrared rays are a kind of heat light invisible to the naked eye. It has a longer wave band below 800°C, and has shorter far-infrared radiation when it is above 800°C. Most of the existing far-infrared energy-saving coatings have problems such as narrow application range, poor permeability, or different expansion coefficients from the substrate to be coated, long-term service performance decline, and even cracks. Far-infrared ceramic coating is a ceramic powder material with high radiation rate and radiation intensity in the far-infrared band, which is prepared by ceramic powder processing...
