Abstract

The invention relates to a camouflage coating for preventing the detection and reconnaissance of visible light and near infrared and a preparation method thereof. The camouflage coating comprises a component A and a component B, wherein the component A comprises the following materials in percentage by weight: 35%-55% of fluorocarbon resin, 20%-30% of camouflage pigments, 5%-7% of flatting agents, 0.1%-2.5% of auxiliary agents and 10%-25% of solvents; the component B comprises aliphatic series polyisocyanate curing agents; and the weight ratio of the component A to the component B is 8:1. The preparation method comprises the following steps: component A preparation (slurry preparation, color paste preparation and coating preparation) and component B preparation. The camouflage coating disclosed by the invention realizes the optical camouflage within visible light and near infrared bands through scientific proportion and reasonable combination by adopting the fluorocarbon resin and matching selected pigments, thereby protecting the target object. The camouflage coating disclosed by the invention has the advantages of convenience for construction, excellent outdoor durable property, good heat resistance, good color retention and high corrosion resistance, meets the requirement for using condition in a harsh environment and is suitable for the camouflage, corrosion prevention, decorative coating of important facilities and buildings and military equipment and equipment.

Description

technical field [0001] The invention relates to a coating, in particular a fluorocarbon camouflage coating for preventing visible light and near-infrared detection and a preparation method thereof. Background technique [0002] With the development of science and technology, human beings have developed from visual reconnaissance to imaging reconnaissance. Since the 1960s, various detection instruments have developed rapidly, such as near-infrared photography, thermal infrared imaging, low-light night vision, radar imaging, and multispectral imaging. Reconnaissance and detection methods such as laser detection and laser detection have come out one after another and developed rapidly. In the face of all-round, multi-level, multi-band, and multi-method photoelectric reconnaissance, various camouflage or stealth methods can be used for the target, such as natural concealment, camouflage paint, wave-absorbing paint, bait, etc. Among them, camouflage paint is widely used because ...
