Furthermore, the periphery of the camouflage net unit is provided with a covered edge, the covered edge is provided with a steel plastic spraying hook with self locking, the camouflage net units are connected through the plastic spraying hook, and the camouflage net units are respectively provided with a reinforcing rope in the longitudinal direction and the transverse direction.
Furthermore, the plastic spraying hook is arranged at the corresponding point of the net corner of the camouflage net and the rope end of the reinforcing rope.
Furthermore, the rice grain-shaped patterns can be replaced by square patterns or square patterns with rice grain shapes inside.
Further, the first pattern is one of, but not limited to, a spherical pattern or a leaf pattern.
Further, the foam base layer can adopt a single layer, or adopt a plurality of layers which are randomly overlapped through thermal compounding or gluing.
Furthermore, the thickness of the foam base layer is 0.5-10 mm, and the thickness of a single layer of the foam base layer is 0.5-1 mm.
Furthermore, the coating surface layer is provided with the waterborne polyurethane coating which has high strength, high chroma, wear resistance, high and low temperature resistance, weathering resistance, tensile resistance and air permeability.
Furthermore, the foam base layer is made of polyethylene or polypropylene or polyolefin with a flame retardant function.
The invention has the following beneficial effects: according to the invention, small rice grain grains are pressed on the foam base layer, so that the scattering of high-frequency-band millimeter waves is realized, and the detection of a millimeter wave radar is protected; the invention can be folded by adopting a plurality of layers of foam base layers at will, and has thin thickness and easy control; the multifunctional waterborne polyurethane coating surface layer is adopted to replace the traditional composite oxford fabric, the multifunctional waterborne polyurethane coating surface layer can be coated at one time, the processing is convenient, the weight of each square of the coating surface layer is 50-150 g, the weight is light, and the light weight of a camouflage net is realized.
