Abstract
The invention relates to a camouflage coating preventing infrared photography and infrared night vision reconnaissance. The coating comprises the following components in percentage by weight: 10-30% of vinylidene chloride resin, 1-10% of modified alkyd resin, 1-15% of mixed pigment, 5-20% of filler, 1-5% of mixing aid, and 35-65% of mixed solvent. The invention further provides a preparation method and an application of the camouflage coating suitable for large weapons to prevent the infrared photography and the infrared night vision reconnaissance. According to the camouflage coating disclosed by the invention, the vinylidene chloride resin is modified with the alkyd resin to serve as film-forming resin base stock, pigments are selected and compounded, aids are selected and compounded, two roller machines are used for dispersion so as to achieve a preset fineness, and thus, the functional requirements on suitability to the large weapons and the camouflage effect are finally met.
Description
Technical field
The present invention relates to the coating industry in chemical industry, specifically, relate to cooperation and the processing technology of coating, more particularly, relate to and be a kind ofly applicable to large-scale weapons anti-infrared and take a picture and the camouflage paint of infrared night vision scouting and the preparation method and application of this coating.
Background technology
It is the most common in military affairs is also one of the most ripe Detection Techniques that visible ray and near infrared scout detection, its principle of work mainly utilizes object and background to the difference of visible ray and near infrared light reflectivity, produce larger contrast contrast gradient on the detector, thus detect target in background.
For the military target of non high temperature, the source of visible ray and near infrared light both can be sunlight, also can be the artificial lights such as infrared illumination bullet.Detect to defend the scouting of enemy to visible ray and near infrared light, the Camouflage painting of visible ray and near infrared light is obtained in countries in the world and develops rapidly, its Main Function is that paint is at target surface, by the reflection of simulation background to visible ray and near infrared light, thus reduce the contrast gradient of object and background at visible ray and near-infrared band.How to make camouflage paint well be attached on large-scale weapons, and desirable reflectivity be provided thus reach the camouflage effectiveness of expection, be this area coating industry one of the aspect that will pay close attention to emphatically.
Camouflage paint involved in the present invention develops just under this market background.This camouflage paint is by supervinyi chloride resin, and Synolac and urethane resin carry out modification, is equipped with chrome yellow, titanium dioxide pigment, charcoal blacks and reach the reflectivity requirements met in visible ray and near infrared range.
