Embodiment 1

[0018] Embodiment 1: A novel zinc-based infrared coating with adjustable infrared emissivity. In the novel zinc-based infrared coating of the present invention, the zinc powder plays a catalytic role in the heating process, so that the carbonization of the compound in the coating occurs while the metal Oxidation, these nano-substances recombine to change the original state of the coating, and finally change the size of the infrared emissivity, and change the light absorption of a certain wavelength, especially for ultraviolet to near infrared, the absorption of light is significantly reduced. Specifically made through the following steps:

[0019] 1) Take 50 parts by mass of zinc powder, 20 parts by mass of component A of polyurethane AB material, and 20 parts by mass of component B of polyurethane AB material, put in 20 parts by mass of butyl acetate, mix and stir evenly;

[0020] 2) Take the mixed solution obtained in step 1), and use a pen to evenly coat the metal aluminum ...

Abstract

The invention discloses a novel zinc-based infrared coating, and relates to an infrared coating, in particular to an emissivity-adjustable novel zinc-based infrared coating. The novel zinc-based infrared coating is characterized by being mixed by polyurethane AB materials, zinc powder and butyl acetate. The novel zinc-based infrared coating is adjustable in terms of emissivity at a certain wave band, absorption strength and absorption strength from an ultraviolet band to a near-infrared band.

Description

technical field [0001] The invention relates to an infrared coating, in particular to a novel zinc-based infrared coating with adjustable emissivity developed by using zinc as a filler. Background technique [0002] Infrared coatings are popular due to their advantages of convenient manufacturing and construction, low cost, and application not limited by geometric shapes, especially in the fields of chemical equipment and building temperature control, and equipment infrared stealth. As a coating, strong adhesion and fast film formation are urgently needed solutions. In addition, for infrared stealth materials, the emissivity can be adjusted, so that the camouflage net and ground targets can be thermally segmented and thermally deformed flexibly and effectively. So as to achieve the purpose of stealth. Therefore, it is extremely important to research and prepare infrared coatings with strong adhesion, fast film formation and adjustable infrared emissivity.
