Problems solved by technology

[0004] The essence of infrared stealth is to weaken the radiation characteristics such as energy, frequency band, heat source and direction through various technical measures, reduce the difference between the infrared radiation of the target and the background, so that the detector cannot receive enough energy, thereby reducing the detection and identification of the target. and the probability of tracking

Abstract

The invention discloses a novel low-infrared-emissivity corrosion-resistant coating comprising the components of, by weight, 80 parts of polyurethane, 120 parts of maleic-anhydride-modified ethylene propylene diene monomer (EPDM) rubber, 0-50 parts of floating flake-shaped Al powder, 0-50 parts of floating flake-shaped Cu powder, 10-20 parts of a silane coupling agent KH550, 10-20 parts of xylene, and 4-8 parts of cyclohexane. The prepared coating has low infrared emissivity, and the corrosion resistance of the modified coating is greatly improved. The method has good application prospect.

Description

technical field [0001] The invention relates to a special paint, in particular to a novel paint with low infrared emissivity and good corrosion resistance. Background technique [0002] Since precision-guided weapons were first used in warfare in the 1970s, precision-guided weapons and guidance technology have played a pivotal role in all previous wars. And with the constant changes in the war situation and the gradual emergence of information-based warfare, the characteristics of precision-guided weapons make it the focus of military development in various countries. As an important member of the precision-guided weapon family, the infrared detection-guided weapon has shown its superiority: it has high precision, high sensitivity, high resolution, high frame rate (staring infrared), strong anti-interference, and can automatically identify targets. Even the key parts of the target, which can work day and night, have been widely used in guided missiles and smart ammunition. ...
