▎ 摘　　要

NOVELTY - Preparing infrared absorption coating with wide spectrum and low heat capacity, comprises (i) grinding thermoelectric ceramic substrate and polishing for pretreatment; (ii) obtaining paint by means of physical and chemical dispersion; (iii)spraying coating on the surface of the pretreated thermoelectric ceramics, curing, to obtain broad-spectrum absorption coating. USE - The coating is useful in the preparation process of the low heat capacity resin coating (claimed). ADVANTAGE - The prepared coating has good wide spectrum infrared absorption effect and sensor amplification effect, good impact resistance and good heat resistance, and effectively avoids the hygroscopicity of the coating, and has wide development prospect. The method is convenient to use and preparation method, reduces the redundant process operation, which not only can effectively save cost, but also can accelerate the application efficiency of coating and has very excellent applicability.
