Abstract

The invention relates to an infrared radiation enhanced coating and a preparation method thereof. The downconversion frequency shift infrared radiation enhanced coating is characterized by consisting of the following components in percentage by mass: 20 to 50 percent of radiation synergistic enhancer, 1 to 7 percent of downconversion frequency shift additive, 15 to 45 percent of high-temperature resistant base stock, 32 to 50 percent of high-temperature binder, 1 to 4 percent of flexibilizer and 1 to 4 percent of coating auxiliary agent, and the sum of the mass percentage of the components is 100 percent. The coating not only has high emissivity and good thermal shock resistance, but also can convert visible light into infrared radiation; and the thermal conversion efficiency of the coating is effectively improved.

Description

technical field [0001] The invention relates to an infrared radiation coating and a preparation method thereof. Background technique [0002] Infrared radiation coatings are applied to the heat-absorbing surfaces of various industrial furnaces and civil boilers. Using the principle of high absorption rate and high emissivity of the coating on thermal radiation, it can improve the absorption of furnace flame heat by the furnace lining or boiler tube wall. Improve furnace heat exchange conditions, increase thermal efficiency, and at the same time have good protection against high temperature oxidation for furnace lining materials, prolong the service life of furnaces and boilers, and reduce maintenance workload. In addition, by strengthening the radiation heat transfer in the furnace, the temperature uniformity of the thermal field in the furnace and the heating quality of the heated body can be improved, so it has attracted people's attention. Infrared radiation coating, as ...
