[0023] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0024] The terms “outer layer”, “inner layer” and “outer surface” are based on the normal use state of the camouflage net and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0025] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0026] The utility model discloses a camouflage net, comprising a grid layer 1, a camouflage outer layer 2 and a waterproof ventilation layer 3. The grid layer 1 has a first surface and a second surface opposite to each other along the thickness direction, and the camouflage outer layer 2 is arranged on the first surface.

[0027] The material of the grid layer 1 is nylon, and the material of the camouflage outer layer 2 is high-strength Oxford cloth. Among them, nylon material has high strength and toughness, can withstand certain pulling and wear, is suitable for building the support structure of the camouflage net, and ensures its stability and durability in harsh environments. Nylon material is relatively light and easy to carry and deploy, which is particularly important for military purposes that require rapid movement and setting. Nylon has good weather resistance and can resist a certain degree of weathering and ultraviolet erosion, extending its service life. Nylon can be easily processed into grids of different shapes and sizes to meet a variety of camouflage needs. Oxford cloth is tough and durable, and can resist physical wear and tear in the natural environment, such as scratching and tearing, and is suitable for long-term outdoor use. In particular, specially treated waterproof Oxford cloth can effectively prevent moisture penetration and has mildew-proof properties, keeping the camouflage net dry and clean in a humid environment and extending its service life. Some Oxford cloth camouflage nets are designed with leaf-like patterns, which can better integrate into the natural environment and provide a more realistic camouflage effect. It has good stealth performance both visually and in the near-infrared spectrum. They have visible light and near-infrared stealth protection functions, which means that they can not only provide camouflage in the visible light range, but also reduce visibility under near-infrared reconnaissance equipment, improving camouflage efficiency. Due to its diversity, Oxford cloth camouflage nets are suitable for military camouflage training, as well as for civil decoration, film and television bases, theme parks and other scenarios. Oxford cloth is usually easy to clean and dry quickly, which is convenient for quick cleaning and maintenance after use.

[0028] The printing processes on the outer surface of the camouflage outer layer 2 include water printing, paint printing, transfer printing and color paste coating, and the water printing process has the best color fastness of the fabric.

[0029] In some embodiments, the waterproof ventilation layer 3 is disposed between the grid layer 1 and the camouflage outer layer 2 and is provided with ventilation holes (not shown) that open when heated or shrink when cooled, which can effectively solve the shortcomings of nylon that it easily absorbs moisture and affects its physical properties, and increases weight in a humid environment.

[0030] In some embodiments, the waterproof ventilation layer 3 is disposed on the second surface of the grid layer 1 and is provided with ventilation holes that open when heated or shrink when cooled.

[0031] In some embodiments, the waterproof ventilation layer 3 is disposed between the grid layer 1 and the camouflage outer layer 2, as well as on the second surface of the grid layer 1, and is provided with ventilation holes that open when heated or shrink when cooled.

[0032] Furthermore, the waterproof ventilation layer 3 includes a negative heat material, which includes but is not limited to β -Eucryptite. Negative thermal material is a material that shrinks when heated and expands when cooled, and β-eucryptite is a negative thermal expansion material with excellent performance, which can trigger negative thermal expansion behavior at room temperature and lower temperatures. Therefore, when the temperature is high during the day, the volume of this β-eucryptite negative thermal material will shrink accordingly, causing a certain degree of detachment of the base material in the ventilation layer of the negative thermal material particles, thereby forming air holes. The air holes are in an open state, replenishing the outside air into the space covered or enclosed by the camouflage mesh to improve air permeability. When the outside temperature drops, the volume of the negative thermal material particles will expand as the ambient temperature drops, and the air holes will become smaller or closed to maintain the temperature in the space covered or enclosed by the camouflage mesh. This achieves the effect of breathability and waterproofing.

[0033] In order to prevent the temperature in the space covered or enclosed by the camouflage net from increasing too much or decreasing too much, it also includes a heat-insulating net layer 4, which is the inner surface layer. That is, the grid layer 1 and the waterproof ventilation layer 3 are sandwiched between the camouflage outer layer 2 and the heat-insulating net layer 4. The material of the heat-insulating net layer 4 is polypropylene, which further improves the puncture resistance of the waterproof ventilation layer 3. The colors of the heat-insulating net layer are black, white and green.

[0034] The surface of the camouflage outer layer 2 close to the grid layer 1 is provided with a radar wave absorbing layer 5 and / or an infrared reflecting layer 6, and the radar wave absorbing layer 5 and / or the infrared reflecting layer 6 are sandwiched between the camouflage outer layer 2 and the waterproof ventilation layer 3. Furthermore, the radar wave absorbing layer 5 includes strontium ferrite powder, and / or the infrared reflecting layer 6 is an aluminum-plated layer. Due to the high magnetic permeability, adjustable dielectric constant and magnetic loss characteristics of strontium ferrite powder, it can effectively absorb electromagnetic wave energy within a certain frequency range, including electromagnetic waves in the radar band. The infrared reflecting layer also helps to prevent the rapid dissipation of heat inside the camouflage net, and plays a certain role in heat insulation and heat preservation. Among them, the aluminum-plated layer has a strong ability to reflect light, with a visible light reflectivity of 70-80% and an infrared reflectivity of 75-100%.

[0035] The waterproof ventilation layer 3 is made of a composite of low-density polyethylene and linear low-density polyethylene. Among them, low-density polyethylene (LDPE) has good softness and ductility, soft touch, light texture, and good electrical insulation performance. Linear low-density polyethylene (LLDPE) has higher strength, toughness and rigidity, better heat and cold resistance, and better resistance to environmental stress cracking. The composite of the two improves its durability while ensuring its toughness and flexibility, and is suitable for objects with different outer contours and easy to store.

[0036] The grid layer 1 is a flame-retardant nylon layer, and its flame retardant performance can be improved by flame-retardant modification of nylon fibers. Flame retardants such as phosphorus-based, halogen-based or inorganic flame retardants are added during the nylon polymerization process. These additives can generate a protective layer that isolates oxygen or absorb heat and decompose when the material burns, thereby inhibiting the spread of flames. Or the surface of the grid layer is coated with a first flame-retardant layer 11; a flame-retardant coating is applied to the surface of the nylon grid, which can maintain the original physical properties and increase the flame retardant effect. The coating contains flame retardants and adhesives to ensure that the coating is firm and durable.

[0037] The camouflage outer layer 2 is flame retardant Oxford cloth, which is made of nylon or polyester. The flame retardant performance of Oxford cloth fibers can also be improved by flame retardant modification, and flame retardants can be added during fiber polymerization. Or the surface of the camouflage outer layer is coated with a second flame retardant layer 22.

[0038] The camouflage net is provided with a edging, and a set of opposite edging is provided with a rubber strip (not shown). The rubber strip is soft and easy to bend, and the oppositely arranged rubber strip has a little stiffness, which makes it easy to find the starting edge of storage, and the reel and the rubber strip are clamped and fixed for storage, so as to prevent the camouflage net from getting tangled and improve the storage efficiency.

[0039] The grid layer 1, the camouflage outer layer 2, the waterproof ventilation layer 3 and the heat-insulating mesh layer 4 can be fixed by heat sealing, gluing, or by threading and binding along the layer thickness direction.

The camouflage outer layer 2 is arranged on the first surface, and the waterproof ventilation layer 3 is arranged between the grid layer 1 and the camouflage outer layer 2, and is distributed with air holes that open when heated or become smaller when cooled. The second surface of the grid layer 1 is provided with a heat insulation grid layer 4, and the heat insulation grid layer 4 is the inner surface layer. The surface of the camouflage outer layer 2 close to the grid layer 1 is provided with a radar wave absorbing layer 5 and an infrared reflecting layer 6, wherein the radar wave absorbing layer 5 is closer to the camouflage outer layer 2, and the radar wave absorbing layer 5 and the infrared reflecting layer 6 are sandwiched between the camouflage outer layer 2 and the waterproof ventilation layer 3. Both surfaces of the grid layer 1 are provided with a first flame retardant layer 11, and the waterproof ventilation layer 3 is between the first flame retardant layer 11 and the infrared reflecting layer 6. The surface of the camouflage outer layer 2 close to the grid layer 1 is provided with a second flame retardant layer 22, that is, the second flame retardant layer 22 is sandwiched between the camouflage outer layer 2 and the radar wave absorbing layer 5.
