Problems solved by technology

[0003] However, most of the infrared camouflage paints currently used are single aluminum-silver paste paints, which are silver-gray. This kind of paint can play a good camouflage effect in night scenes, but in daytime scenes, it is impossible to achieve camouflage camouflage with visible light. , therefore, it is of great significance to study a coating with double camouflage effects of visible light camouflage and infrared camouflage

preparation example Construction

[0025] The preparation method of the coating that is used for infrared camouflage provided by the invention comprises the following steps:

[0026] like figure 1 As shown, the metal filler, water, resin and dispersant are mixed and stirred to obtain a dispersion. In this step, mix 1 to 8 parts of metal filler and 1 to 8 parts of water in parts by weight, stir well until the metal filler is evenly mixed in water, then add 0 to 3 parts of diatomaceous earth, stir evenly, and Add 8-15 parts of resin, 0.3-0.8 parts of dispersant, and stir at a speed of 100-200 rpm for 20-40 minutes to obtain a dispersion, wherein the weight ratio of metal filler to water is 1:1. In this step, the metal filler is a combination of one or more of aluminum silver paste, reduced iron powder, and copper powder, wherein the aluminum silver paste is a floating water-based aluminum silver paste; the water is deionized water; the resin is water-based Resin, the resin is a combination of one or more of wat...

Embodiment 1

[0031] In parts by weight, mix 1 part of floating-type water-based aluminum-silver paste with 1 part of deionized water, stir well until the floating-type water-based aluminum-silver paste is uniformly dispersed in deionized water, and then add 0.5 parts of diatomaceous earth, stir well, then add 8 parts of water-based polyurethane resin, 0.3 parts of sulfonate, stir at 100 rpm for 30 minutes to obtain a dispersion, add 1 part of green water-based color paste to the dispersion The coloring pigments are prepared into mixtures with different colors after being fully stirred, and finally 0.3 parts of polyoxypropylene glyceryl ether and 0.3 parts of diphenylpolysiloxane are added to the mixture to prepare a coating that can be used for infrared camouflage.

Embodiment 2

[0033] In parts by weight, mix 8 parts of floating-type water-based aluminum-silver paste with 8 parts of deionized water, stir well until the floating-type water-based aluminum-silver paste is uniformly dispersed in deionized water, and then add 3 parts of diatomite, stir evenly, then add 15 parts of water-based polyurethane resin, 0.8 part of sulfonate, stir at 200rpm for 25 minutes to obtain a dispersion, add 5 parts of green and black in different proportions to the dispersion The coloring pigment prepared by the water-based color paste, after being fully stirred, is blended into a mixture with different colors, and finally 0.8 parts of polyoxypropylene glyceryl ether and 0.8 parts of diphenyl polysiloxane are added to the mixture to obtain a color that can be used for infrared camouflage. coating.

Abstract

The invention provides a coating and a preparation method thereof. The preparation method comprises the following steps: mixing metal fillers, water, water-based resin and a dispersant; then, adding acoloring pigment; and finally, adding a defoaming agent and a levelling agent to prepare the coating for infrared camouflage. The coloring pigment is added into a low-infrared emissivity coating to obtain coatings available for infrared camouflage with different emissivity and different colors in the invention; the coating can realize a double-camouflage effect of visible light camouflage and infrared camouflage at the same time; the preparation method provided by the invention is simple to operate and easy to produce on a large scale; and the provided coatings available for infrared camouflage can be applied to visible light and infrared camouflaged fabrics and then processed into battle dress uniforms, camouflage nets, tents and other products.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating for infrared camouflage and a preparation method thereof. Background technique [0002] The basic principle of camouflage paint is to reduce the difference in scattering or radiation characteristics between the target and the background in the visible light, near-infrared, and thermal infrared bands, so as to conceal the target or reduce the detectable characteristics of the target. Visible light camouflage paint is to use camouflage paint under visible light to produce a color consistent with the background. Infrared camouflage paint is to make the infrared radiation characteristics of the target and the background consistent as much as possible by changing the radiation intensity of the target, that is, to reduce or eliminate the infrared radiation difference between the target and the background, and destroy the shape of the camouflaged object. So as to achieve the purpose o...
