Description

Technical Field

[0001] This invention relates to the field of camouflage technology, and in particular to a high-temperature resistant camouflage net and its preparation method. Background Technology

[0002] Camouflage nets are an important camouflage and concealment tool, primarily used to conceal and protect various targets, making them difficult to detect. With continuous technological advancements, reconnaissance techniques are constantly innovating and upgrading. For example, high-resolution satellites can monitor the dynamic changes of ground targets in real time, capturing minute details. Combined with artificial intelligence and machine learning technologies, they can analyze massive amounts of data in real time, quickly identifying patterns, anomalies, and predicting potential threats. Furthermore, drones equipped with various reconnaissance devices and small weapons can cruise in the air for extended periods, providing comprehensive, all-weather, and all-time reconnaissance coverage of targets. These emerging reconnaissance technologies increase the threat to target detection, placing higher demands on camouflage nets to maintain effective camouflage in all operational states, especially for camouflage during the launch phase of some equipment. Existing ordinary camouflage nets need to be removed during missions to prevent ablation by the high-temperature exhaust flames. Even if some camouflage nets have flame-retardant properties, and the launching equipment carries them on missions, the nets will still be severely damaged by the exhaust flames after the mission, rendering them unusable. In the existing technology, most high-temperature camouflage nets have complex structures. For example, Chinese patent "202220974847.X" discloses a fireproof double-sided camouflage net, which includes a first camouflage net layer, a second camouflage net layer, an inflatable airbag, a fireproof and flame-retardant bag, etc. The structure is complex and cannot resist the scouring of high-speed airflow, which makes it difficult to meet the requirements of high-temperature tail flame.

[0026] An optical camouflage coating is formed by coating the third high-temperature resistant coating onto the formed flame-retardant coating.

[0027] The high-temperature resistant base fabric coated with the radar camouflage coating, the flame retardant coating and the optical camouflage coating is cut into flower decorative fabric;

[0028] After stretching the cut flower decorative fabric, tie the cut flower decorative fabric to the bottom net using several of the binding ropes;

[0042] The beneficial effects of this invention are as follows:

[0043] This invention provides a high-temperature camouflage net. The main structure of the high-temperature camouflage net consists of a base net and a decorative fabric bound with cut flowers. The structure is simple, easy to manufacture, convenient to store, lightweight, and easy to transport. When camouflage is required, simply unfold the base net with the decorative fabric bound to it and lay it on the target for quick and convenient camouflage. Furthermore, the edges of the decorative fabric and the base net are wrapped and fixed by edge ropes, preventing the edges of the decorative fabric from separating from the base net. This prevents the high-temperature camouflage net from curling under the impact of high-speed airflow, improving its reliability. Simultaneously, the base net, decorative fabric, binding ropes, and edge ropes are all made of high-temperature resistant fibers, possessing excellent high-temperature resistance. This makes the high-temperature camouflage net suitable for targets spraying high-temperature exhaust plumes. The high-temperature camouflage net does not need to be removed during missions and can remain in normal condition after use. It not only provides excellent camouflage but is also reusable, saving costs.

[0044] This invention also provides a method for preparing a high-temperature resistant camouflage net. The prepared high-temperature resistant camouflage net has the advantages of simple structure, lightweight and easy storage, good reliability and good camouflage effect, and is suitable for targets to be camouflaged by ejecting high-temperature exhaust flames.

[0052] To facilitate understanding of the present invention, a more comprehensive description will be provided below. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention. Unless otherwise defined, all technical and scientific terms used in this invention pertain to the technical field of the invention.

[0053] like Figures 1 to 3 As shown, this embodiment provides a high-temperature camouflage net, which includes a base net 1, a decorative cut fabric 2, several binding ropes, and several edge ropes 3. The decorative cut fabric 2 is bound to the base net 1 by several binding ropes, with each rope wrapping around one side of the decorative cut fabric 2 and fixing it to one side of the base net 1. The base net 1 and the bound decorative cut fabric 2 form the main structure of the high-temperature camouflage net, which is simple in structure, easy to manufacture, easy to store, lightweight and easy to transport. When it is necessary to camouflage a target, simply unfold the base net 1 with the decorative cut fabric 2 bound to it and lay it on the target to cover and camouflage the target, which is relatively quick and convenient to use. Furthermore, the edge ropes 3 wrap and fix the edges of the decorative cut fabric 2 and the edges of the base net 1, making it difficult for the edges of the decorative cut fabric 2 to separate from the base net 1. This prevents the high-temperature camouflage net from curling under the scouring action of high-speed airflow during use, which helps to improve the reliability of the high-temperature camouflage net.

[0054] The system comprises a base net 1 made of high-temperature resistant fiber warp-knitted mesh fabric, binding ropes made of high-temperature resistant fiber hook lines, and edge ropes 3 made of high-temperature resistant fiber woven ropes. The decorative cut fabric 2 includes a high-temperature resistant base fabric 21 and radar camouflage coating 22, flame-retardant coating 23, and optical camouflage coating 24 sequentially coated onto the base fabric 21. The base fabric 21 is made of high-temperature resistant fiber fabric. The base net 1, decorative cut fabric 2, binding ropes, and edge ropes 3 are all made of high-temperature resistant fibers, possessing excellent high-temperature resistance. This makes the high-temperature camouflage net suitable for targets that emit high-temperature exhaust flames (where high-temperature exhaust flames refer to jet flames with an instantaneous temperature not lower than 600℃). Furthermore, the high-temperature camouflage net does not need to be removed from the target during missions, and it can remain in normal condition after use. This not only provides excellent camouflage for the target but also allows for reuse, saving costs.

[0055] Understandably, the cut flower decorative fabric 2 can be U-shaped cut flowers, which are stretched and tied to the base net 1 to form a three-dimensional flower effect with a certain degree of visibility.

[0056] Preferably, the mesh size of the high-temperature resistant fiber warp-knitted mesh fabric is less than 5mm, such as 3mm or 4mm, and is set according to actual needs. The appropriate mesh size of the high-temperature resistant fiber warp-knitted mesh fabric helps to ensure the structural strength of the high-temperature resistant camouflage net, while ensuring that the visibility of the cut flower decorative fabric 2 is within a preset range after installation, such as 10%-30%, thus ensuring a better camouflage effect.

[0057] In this embodiment, the high-temperature camouflage net also includes several fixing ropes 4, one end of each fixing rope 4 being fixedly connected to one side of the base net 1, for example, tied tightly to the base net 1. The fixing ropes 4 are used to connect to the target after the high-temperature camouflage net is covered on it, so that the high-temperature camouflage net is stable on the target, ensuring stability and reliability in use. Preferably, the fixing ropes 4 are high-temperature resistant fiber ropes.

[0058] Alternatively, the high-temperature resistant fibers include aramid fibers, polytetrafluoroethylene fibers, polyimide fibers, and other high-temperature resistant fibers.

[0059] Specifically, the radar camouflage coating 22 is formed by coating a first high-temperature resistant coating onto a high-temperature resistant base fabric 21, for example, by applying it using a precision coating machine. The first high-temperature resistant coating includes a first component A and a first component B. The first component A includes 100 parts of silicone rubber matrix, 10-50 parts of radar absorber, 30-60 parts of solvent, 1-1.5 parts of reinforcing agent, 1-2 parts of antioxidant, and 1-2 parts of mildew inhibitor. The third component B includes 2-3 parts of crosslinking agent. For example, the radar absorber may be present in weights of 10, 20, 30, 40, or 50 parts; the solvent in weights of 30, 40, 50, or 60 parts; the reinforcing agent in weights of 1, 1.3, or 1.5 parts; the antioxidant in weights of 1, 1.5, or 2 parts; the mildew inhibitor in weights of 1, 1.5, or 2 parts; and the crosslinking agent in weights of 2, 2.5, or 3 parts.

[0060] Specifically, the flame-retardant coating 23 is formed by applying a second high-temperature resistant coating onto the radar camouflage coating 22, for example, by using a precision coating machine. The second high-temperature resistant coating includes a second component A and a second component B. The second component A includes 100 parts of silicone rubber matrix, 30-60 parts of solvent, 10-50 parts of flame retardant, 1-1.5 parts of reinforcing agent, 1-2 parts of antioxidant, and 1-2 parts of mildew inhibitor. The second component B includes 2-3 parts of crosslinking agent. For example, the flame retardant may be present in parts by weight of 10, 20, 30, 40, or 50 parts; the solvent in parts by weight of 30, 40, 50, or 60 parts; the reinforcing agent in parts by weight of 1, 1.3, or 1.5 parts; the antioxidant in parts by weight of 1, 1.5, or 2 parts; the mildew inhibitor in parts by weight of 1, 1.5, or 2 parts; and the crosslinking agent in parts by weight of 2, 2.5, or 3 parts.

[0061] Specifically, the optical camouflage coating 24 is formed by coating a third high-temperature resistant coating onto the flame-retardant coating 23, for example, by applying it using a precision coating machine. The third high-temperature resistant coating includes a third component A and a third component B. The third component A includes 100 parts of silicone rubber matrix, 10-50 parts of heat-resistant pigment, 30-60 parts of solvent, 1-1.5 parts of reinforcing agent, 1-2 parts of antioxidant, and 1-2 parts of mildew inhibitor. The third component B includes 2-3 parts of crosslinking agent. For example, the heat-resistant pigment may be 10, 20, 30, 40, or 50 parts by weight; the solvent may be 30, 40, 50, or 60 parts by weight; the reinforcing agent may be 1, 1.3, or 1.5 parts by weight; the antioxidant may be 1, 1.5, or 2 parts by weight; the mildew inhibitor may be 1, 1.5, or 2 parts by weight; and the crosslinking agent may be 2, 2.5, or 3 parts by weight.

[0062] The silicone rubber matrix includes one or more of methyl silicone rubber, methyl vinyl silicone rubber, and methyl phenyl vinyl silicone rubber; the solvent includes one or more of xylene and acetylacetone; the reinforcing agent includes fumed silica; the antioxidant includes antioxidant 4010 (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine); the mildew inhibitor includes LF-1066 mildew inhibitor; the crosslinking agent includes bis(2,5-dimethyl)sulfide; the flame retardant includes one or more of polyphosphate flame retardants, melamine, and antimony trioxide; the radar absorber includes one or more of carbon-based iron powder, iron-nickel alloy powder, carbon black, graphite, and graphene; and the heat-resistant pigment includes one or more of iron oxide red, chromium oxide green, cobalt blue, medium chrome yellow, titanium nickel yellow, and carbon black.

[0063] like Figures 1 to 4 As shown, this embodiment also provides a method for preparing a high-temperature resistant camouflage net, which is used to prepare the above-mentioned high-temperature resistant camouflage net.

[0100] S3: Apply the first high-temperature resistant coating onto the high-temperature resistant base fabric 21 to form a radar camouflage coating 22;

[0101] S4: Apply a second high-temperature resistant coating to the formed radar camouflage coating 22 to form a flame-retardant coating 23;

[0102] S5: Apply a third high-temperature resistant coating to the formed flame-retardant coating 23 to form an optical camouflage coating 24;

[0103] By forming a radar camouflage coating 22, the high-temperature camouflage net can evade radar detection and has a good camouflage effect. By forming an optical camouflage layer, the high-temperature camouflage net can closely resemble the color of the environment, improving the camouflage effect on the target. By forming a flame-retardant layer, the high-temperature resistance of the high-temperature camouflage net can be improved and it can be effectively prevented from being burned and damaged by high-temperature exhaust flames during use. Moreover, the radar camouflage coating 22, the flame-retardant coating 23, and the camouflage coating all use an organosilicon rubber matrix, which further improves the high-temperature resistance of the high-temperature camouflage net. They also all use anti-aging agents, anti-mildew agents, and reinforcing agents, which can effectively improve the structural strength, service life, and reliability of the high-temperature camouflage net.

[0104] S6: Cut the high-temperature resistant base fabric 21 coated with radar camouflage coating 22, flame retardant coating 23 and optical camouflage coating 24 to obtain cut decorative fabric 2;

[0105] For example, a high-temperature resistant base fabric 21 coated with radar camouflage coating 22, flame retardant coating 23 and optical camouflage coating 24 is cut into U-shaped patterns to form a cut decorative fabric 2.

[0106] S7: After stretching the cut flower decorative fabric 2, tie the cut flower decorative fabric 2 to the bottom net 1 with several binding ropes;

[0107] Among them, the mesh size of the high-temperature resistant fiber warp-knitted mesh fabric is less than 5mm, such as 3mm, 4mm, etc., and the specific size is set according to actual needs. The appropriate mesh size of the high-temperature resistant fiber warp-knitted mesh fabric is conducive to ensuring the structural strength of the high-temperature resistant camouflage net.

[0108] After the U-shaped cut floral decorative fabric 2 is tied to the base net 1, it forms a three-dimensional floral effect with a certain degree of transparency, for example, a transparency of 10%-30%.

[0109] S8: After wrapping each side cord 3 with one side of the cut flower decorative fabric 2, sew it onto one side of the bottom net 1.

[0110] By wrapping the edge of the decorative fabric 2 around the edge rope 3 and then sewing it onto the base net 1, the edge of the decorative fabric 2 is less likely to separate from the base net 1. This makes the final high-temperature resistant camouflage net less prone to curling under the scouring action of high-speed airflow during use, which helps to improve the reliability of the high-temperature resistant camouflage net.

[0111] Preferably, several fixing ropes 4 are also fixed to the edge of the base net 1. The fixing ropes 4 are used to connect to the target after the high-temperature camouflage net is covered, so as to make the high-temperature camouflage net stable on the target and ensure stability and reliability in use. More preferably, the fixing ropes 4 are high-temperature resistant fiber ropes.

[0112] The high-temperature camouflage net provided in this embodiment was subjected to a 600℃ instantaneous high-temperature flame erosion test. No ignition, curling, rolling, loosening, separation between the cut flower decorative fabric 2 and the base net 1, or coating peeling off the cut flower decorative fabric 2 occurred. In other words, the high-temperature camouflage net remained in a normal state, indicating that the high-temperature camouflage net has good high-temperature resistance and erosion resistance, and has a simple structure, is easy to store and transport, and has good convenience and reliability in use.
