Abstract

The invention belongs to the technical field of pain coating and particularly relates to an environment-friendly bicomponent waterborne polyurethane camouflage paint preparation method. Green waterborne camouflage paint is prepared from 25-32wt% of waterborne emulsion, 10-15wt% of fillers, 15-20wt% of pigments, 20-30wt% of distilled water, 0.3-0.5wt% of an antifoaming agent, 0.3-0.5wt% of a dispersing agent, 0.3-0.5wt% of a flatting agent, 0.3-0.5wt% of a wetting agent, 0.3-0.5wt% of a thickening agent, 10-13wt% of a curing agent, wherein the pigments include 8-10% of an inorganic green pigment, 3-4% of an inorganic yellow pigment, 2-3% of an inorganic black pigment and 2-3% of inorganic blue pigment. The waterborne emulsion refers to hydroxyl acrylic emulsion; the curing agent refers to waterborne isocyanate; the fillers and the pigments include talcum powder, light calcium carbonate, fumed silica, the inorganic green pigment, the inorganic yellow pigment, the inorganic black pigment and the inorganic blue pigment; auxiliaries include the antifoaming agent, the flatting agent, the dispersing agent, the wetting agent and the thickening agent. The waterborne camouflage paint is effective in camouflage and excellent in salt spray resistance, water resistance, corrosion resistance and physical and mechanical properties and can be used for camouflage of military equipment.

Description

technical field [0001] The invention belongs to the technical field of paint coating, and in particular relates to a preparation method of an environment-friendly two-component water-based polyurethane camouflage paint. Background technique [0002] With the development of military high-tech and the advancement of reconnaissance technology, reconnaissance equipment at home and abroad is changing with each passing day. There are ultraviolet photographic equipment that work in the ultraviolet band, telescopes, optical rangefinders, etc. that work in the visible light band, and infrared night vision devices and CCD optical imaging systems that work in the near-infrared band. Reconnaissance equipment working in the infrared band has multi-spectral band infrared photographic equipment and thermal infrared imaging systems, which greatly enhance the ability to distinguish camouflaged targets. Necessary measures to effectively preserve the vitality. [0003] At present, disclosed ...
