Abstract

The invention discloses an infrared radiation coating for a lining surface of an industrial furnace, which is prepared by the following raw materials in percentage by mass: 30-60% of spinel and silicate multi-phase composite system infrared radiation powder, 1-10% of inorganic combination addition agent, 25-60% of bonder, 0-2% of anti-settlement agent, 0-1% of dispersing agent, 0-1% of defoaming agent, and 0-1% of flatting agent. The invention further discloses a method for using the infrared radiation coating. After the coating disclosed by the invention is dried and solidified, a formed coated surface is compact and has good infrared radiation performance and can be firmly combined with substrates, such as fire-proof material, metal and the like. After being used at high temperature fora long time, the coated surface cannot be split and fallen off, can resist corrosion and has good thermal shock resistance performance.

Description

technical field [0001] The invention relates to the field of infrared radiation energy-saving materials, in particular to an infrared radiation coating that can be firmly combined with refractory materials, metals and other substrates and its application method. Background technique [0002] Infrared radiation is an electromagnetic wave with a wavelength in the range of 0.76μm-1000μm. Thermal effect is its basic feature.
