Infrared stealth coating, preparation method thereof, infrared stealth fabric and preparation method of infrared stealth fabric

Abstract

The invention discloses an infrared stealth coating, a preparation method thereof, infrared stealth fabric and a preparation method of the infrared stealth fabric. The infrared stealth coating is prepared from a composite pigment and an adhesive, wherein the composite pigment contains aluminium paste and a color pigment; the adhesive contains any one of aliphatic elastic polyurethane, one-component elastic polyurethane and epoxy resin; the infrared stealth fabric is obtained by spraying the infrared stealth coating to at least one surface of a substrate. Compared with the prior art, the infrared stealth coating and the infrared stealth fabric with low emissivity have the advantages that human bodies and military weapons can be camouflaged and shielded effectively, probability that the human bodies and the military weapons are detected by an infrared detector is reduced, the coating and the substrate are better bound, and probability of powder falling, cracking and even falling off of the coating from the substrate is reduced.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an infrared stealth paint and a preparation method thereof, an infrared stealth fabric and a preparation method thereof. Background technique [0002] Under modern high-tech combat conditions, the rapid development of infrared detection technology has seriously threatened the safety and vitality of soldiers participating in the war. More and more countries have begun to devote themselves to the research of individual infrared stealth technology. The main way to realize individual red stealth is to use infrared stealth textile materials to reduce the infrared radiation intensity of individual soldiers and their identifiability in the background. However, the special organic molecular structure and organizational structure of ordinary textile materials make the surface infrared radiation intensity very high, and it is difficult to avoid the detection and tracking of infrared detect...

AI Technical Summary

Problems solved by technology

However, the special organic molecular structure and organizational structure of ordinary textile materials make the surface infrared radiation intensity very high, and it is difficult to avoid the detection and tracking of infrared detectors.

[0003] In the prior art, low-emissivity coatings are often applied to the surface of textile materials by scraping or spraying to reduce the infrared radiation intensity of textile materials, but this method can only reduce the emissivity of textile materials to 0.5 Left and right, it cannot meet the requirements of the stealth performance of combat equipment under modern high-tech combat conditions, and the adhesion between coatings and textile materials is poor, and the coatings coated on the surface of textile materials are prone to powder falling, cracks or even falling off
