Problems solved by technology

Among them, reducing the emissivity of the object surface is one of the most important methods of thermal infrared stealth at present. The materials that can reduce the emissivity are generally metal materials and semiconductor materials with high reflectivity, and semiconductor materials, as new stealth materials, are still under research. stage, the cost is high, and it cannot be put into use in large quantities. The preparation of metal materials is simple and the cost is low, but the stealth of pure metal materials in the visible light-near-infrared band is easy to appear, and the addition of corresponding coloring pigments will make the emission in the infrared band Therefore, how to prepare low-cost, multi-band stealth color coatings is the focus of military research in various countries

Abstract

The invention discloses infrared brown camouflage paint and a preparation method and application thereof. The infrared brown camouflage paint consists of the following components in parts by weight: 5-15 parts of brown pigment, 5-20 parts of yellow pigment, 2-5 parts of protective colloid, 5-20 parts of functional filler, 15-30 parts of adhesive and 10-50 parts of water. The preparation method of the infrared brown camouflage paint comprises the following steps: mixing the brown pigment, the yellow pigment, the protective colloid, the functional filler, the adhesive and the water in proportion; and performing ultrasonic dispersion for 0.5-1 hour firstly and then carrying out mechanical stirring for 1-10 hours to obtain the infrared brown camouflage paint. The infrared brown camouflage paint disclosed by the invention has the characteristic of low infrared emissivity, wherein the emissivity reaches 0.69-0.79 at the wavelength of 8-14 microns and basically meets the requirement of infrared camouflage; and meanwhile, the infrared camouflage paint disclosed by the invention is brown which is one of the basic colors of visible light camouflage and realizes a good visible light-near infrared multi-band camouflage compatible effect.

Description

technical field [0001] The invention relates to an infrared brown stealth coating and a preparation method and application thereof, belonging to the field of textile material science. Background technique [0002] Any object whose temperature is above absolute temperature zero is always radiating electromagnetic waves of different wavelengths to the surrounding space, and the electromagnetic radiation with a radiation wavelength range of 0.76-1000 μm is called infrared radiation. Generally, electromagnetic waves in this band range are called infrared rays. . [0003] As an electromagnetic wave, infrared rays follow the laws of wave absorption, reflection and scattering during transmission, and are also absorbed and scattered by various solid particles, water vapor and other gas molecules in the atmosphere during transmission, making the infrared radiation energy Attenuation occurs, but infrared rays in the following bands can penetrate the atmosphere without attenuation: 1-...
