Problems solved by technology

[0002] At present, the thermal emissivity ratio of high-efficiency coatings is usually below 0.9. At the same time, as the temperature increases, the coating is prone to peeling off, chalking, and discoloration. Variation decomposition leads to the attenuation of the thermal emission ratio of the coating, which seriously affects the use effect

Abstract

The invention provides an infrared high-emission coating and a preparation method thereof and belongs to a functional coating film. The coating comprises a component A and a component B, wherein the component A is used as a main coating and contains a filler, a film forming matter and additives; the ilmenite type nano-composite oxide subjected to high-temperature calcinations hybridization treatment is used as the filler; the film forming matter includes one or two of organic silicon modified resin and fluorocarbon resin, a solvent n-butyl acetate and dimethylbenzene; the additives include a delustering agent, an anti-flooding agent, a dispersing agent and a flatting agent; a carbimide lipid curing agent is used as the component B. In a use process, the component A and the component B are uniformly mixed at the ratio of 9:(0.5-1); the coating can be utilized to quicken the heat dissipating efficiency of the object surface; the cleanness of the coating surface is guaranteed and the heat emission ratio of the coating is stabilized at the value more than or equal to 0.92 for a long time.

Description

technical field [0001] The invention relates to a functional coating film layer, in particular to an infrared high-emitting coating and a preparation method thereof. Background technique [0002] At present, the thermal emissivity ratio of high-efficiency coatings is usually below 0.9. At the same time, as the temperature increases, the coating is prone to peeling off, chalking, and discoloration. The variation decomposition leads to the attenuation of the thermal emissivity ratio of the coating, which seriously affects the use effect. Contents of the invention [0003] The technical problem to be solved in the present invention is to address the deficiencies of the prior art, and propose a high-infrared high-emitting coating that maintains a long-term stable thermal emission specific energy, and a preparation method thereof. [0004] The technical problem to be solved in the present invention is achieved through the following technical solutions, a high-infrared emission...
