Description

Technical Field

[0001] The present invention belongs to the technical field of camouflage materials, and in particular relates to a wear-resistant camouflage resin coating material, a preparation method thereof, and an application thereof. Background Art

[0002] In the security field, camouflage technology, a key means of concealing targets and enhancing survivability, is rapidly developing towards multi-band composite camouflage. Camouflage nets, as core camouflage equipment, have seen their surface coating technology evolve from a single function to a composite technology capable of simultaneously achieving multi-spectral stealth, including optical, radar, and infrared protection, in complex and changing environments. This effectively reduces the risk of detection and significantly enhances the target's survivability.

[0003] However, the complex and ever-changing application environment places extremely stringent demands on the performance of the surface coating of the camouflage net, among which wear resistance becomes a key factor restricting the service life and camouflage effect of the camouflage net. In actual use, the camouflage net needs to frequently deal with natural environmental changes such as wind, sun, and rain, as well as mechanical friction generated during transportation, laying, and winding. These factors can easily lead to problems such as fading, aging, and structural damage to the coating, which greatly reduces the camouflage effect of the camouflage net, and thus seriously affects the concealment and security of the target. Therefore, improving the wear resistance of the surface coating of the camouflage net can not only extend the service life of the camouflage net and ensure that it can continue to stably exert its multi-spectrum stealth performance in complex environments, but also significantly reduce the subsequent maintenance costs, which is of great significance to improving the comprehensive performance of camouflage equipment.

[0004] At present, common camouflage nets are mostly based on polyester plaid cloth embedded with radar metal wires. The radar stealth function is achieved through the reflection, scattering or absorption characteristics of the metal wires on radar waves, and a flame retardant layer is coated on its surface to meet the safety requirements in special environments. However, this composite structure resin coating faces severe challenges in dry friction resistance in actual applications. Frequent mechanical wear can easily lead to scratches, peeling and other failure phenomena on the coating surface, which greatly reduces the multi-spectrum stealth performance of the camouflage net. To solve this problem, existing technologies usually adopt methods such as adding inorganic fillers and increasing the coating thickness to enhance wear resistance. However, these methods often reduce the flexibility of the coating, and it is difficult to control the coating weight to ≤100g / m 2 It is within the scope of industry requirements and cannot meet the development needs of lightweight and high performance camouflage nets.

[0005] Therefore, the technical bottleneck facing existing camouflage coating materials lies in how to significantly improve the dry friction resistance of the camouflage resin coating on the surface, while maintaining or even enhancing the flexibility of the camouflage mesh substrate (especially the polyester radome substrate) and strictly controlling the coating weight (below 100g / m2). This is to withstand mechanical wear in complex environments, extend the service life, and maintain a stable multi-spectrum camouflage effect. In other words, existing technologies fail to effectively resolve the inherent contradiction between wear resistance, flexibility, and lightweight.

[0006] In view of this, this invention is proposed. Summary of the Invention

[0009] In a first aspect, the present invention provides a method for preparing a wear-resistant camouflage resin coating material, comprising the following steps:

[0010] Step 1: coating a flame retardant layer on the surface of a substrate and drying the substrate to obtain a flame retardant layer-coated substrate;

[0011] Step 2, preparing a pigment slurry with a camouflage effect, wherein the pigment in the pigment slurry includes a mixture of one or more of a scarlet pigment, an organic black pigment, a titanium chrome yellow pigment, a cobalt green pigment, a chrome green pigment, a blue pigment, and a white pigment;

[0033] In a third aspect, the present invention further provides an application of the above-mentioned wear-resistant camouflage resin coating material, wherein the wear-resistant camouflage resin coating material is used to enhance the stealth protection capability and mechanical durability of camouflage equipment in complex environments.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. Balance between wear resistance and flexibility / lightweight: The present invention introduces a specific type of organic silicon wear-resistant additive (such as F530-B). This additive has low surface energy characteristics and can effectively migrate to the coating surface during the resin curing process to form a continuous and smooth organic silicon protective film, significantly reducing the friction coefficient of the coating surface, thereby physically reducing mechanical wear. At the same time, the silanol (Si-OH) in its molecular structure can undergo a condensation reaction with active groups such as carboxyl (-COOH) and hydroxyl (-OH) in the resin system to form a stable chemical bond, which not only enhances the overall stability of the coating, but also avoids the problem of decreased flexibility caused by the addition of traditional inorganic fillers. This allows the coating to achieve excellent wear resistance while still maintaining the good flexibility and foldability of the substrate (such as polyester radar cloth).

[0036] 2. Excellent interface bonding performance: The present invention uses a highly efficient adhesion promoter (such as Additive JF-920). The active epoxy group (-CH(O)CH-) on its molecular chain can undergo polymerization reaction with the resin matrix, and can also react with groups such as hydroxyl (-OH) in the flame retardant layer on the surface of the substrate to form a stable ether bond (-COC-) or ester bond (-C(O)O-). This chemical reaction constructs a strong chemical bond network at the interface between the resin coating and the underlying flame retardant layer / substrate, greatly improving the interfacial bonding strength between the coating and the substrate. Even if subjected to strong mechanical friction stress, the coating is not easy to peel or flake off from the substrate, which fundamentally solves the wear resistance problem of the coating caused by interface failure.

[0037] 3. Simple preparation process and convenient production: The raw materials used in the preparation method provided by the present invention are all commercially available industrial materials, with a wide range of sources and controllable costs. The coating and stirring processes involved in the preparation process are simple to operate, and various coating methods such as doctor blade coating, roller coating, gravure printing, or screen printing can be used. This method is suitable for industrial large-scale production. Compared with existing technologies, it reduces production costs and improves production efficiency while ensuring improved product performance, thus showing good economic benefits and market application prospects.

[0038] In summary, the technical solutions provided by this invention, particularly the synergistic effect of the introduction of wear-resistant additives and adhesion promoters, resolve the long-standing conflict in the field of camouflage resin coatings: achieving both enhanced wear resistance and maintained flexibility and lightweight. While ensuring the coating's flexibility and weight meet standards, it significantly enhances dry friction resistance, providing material support for the long-lasting, stable, and multi-spectral stealth protection of camouflaged equipment in complex environments.

[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Instead, they are merely examples consistent with certain aspects of the present invention as detailed in the appended claims.

[0045] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0046] See also Figure 1 The present invention provides a method for preparing a wear-resistant camouflage resin coating material, which specifically comprises the following steps:

[0047] Step 1: Coat the surface of the substrate with a flame retardant layer. Generally, a single layer coating is selected to reduce the weight of the substrate while achieving the flame retardant function. The substrate can be any one of cloth, leather, and high molecular polymer. Preferably, polyester radome is used as the cloth substrate. After coating, dry it at a temperature of 120°C to 150°C for 3min to 10min to obtain a substrate coated with a flame retardant layer. This step provides a flame retardant foundation and a stable base for subsequent coatings.

[0048] Step 2: prepare a pigment slurry with a camouflage effect. The pigment can be selected from a mixture of one or more of scarlet pigment, organic black pigment, titanium chrome yellow pigment, cobalt green pigment, chrome green pigment, blue pigment, and white pigment. Taking the preparation of a dark green camouflage effect pigment slurry as an example, 20% to 35% of deionized water, 0.5% to 3% of an aqueous defoaming agent, 1% to 3% of a wetting dispersant, 1% to 3% of a moisturizing agent, 50% to 70% of a pigment (wherein the pigment consists of 0.2% to 0.7% of a bright red pigment, 1% to 3% of an organic black pigment, 9% to 25% of a titanium chrome yellow pigment, 27% to 60% of a cobalt green pigment, and 15% to 45% of a chrome green pigment, and the sum of the mass percentages of each component is 100%) and 5% to 10% of a matte material are weighed as raw materials, and the sum of the mass percentages of each raw material is 100%. The raw materials are added to a container in sequence, and stirred at a speed of 500 r / min to 1500 r / min using a high-speed disperser for 5 to 15 minutes. After uniform dispersion, a pigment slurry is obtained to give a camouflage color to the coating.

[0049] Step 3. Weigh 30% to 60% of the pigment slurry by mass and put it into a container. First, add 35% to 55% of the water-based resin, 0.5% to 4% of the curing agent, 0.5% to 4% of the light stabilizer, 1% to 2% of the wear-resistant additive and 1% to 2% of the adhesion promoter. Stir the mixture for 5 to 15 minutes at a speed of 500 r / min to 1500 r / min using a high-speed disperser. After uniform dispersion, add 0.5% to 5% of the thickener. The sum of the mass percentages of each component is 100%. Similarly, control the speed and stirring time of the high-speed disperser until the mixture is uniformly mixed to obtain a wear-resistant camouflage resin coating. In this process, the components work synergistically to give the coating excellent properties.

[0050] Step 4: Apply the wear-resistant camouflage resin coating obtained in step 3 to the surface of the substrate coated with the flame retardant layer in step 1 by blade coating, roller coating, gravure printing or screen printing, and dry it at a temperature of 80°C to 170°C for 5min to 60min to obtain a wear-resistant camouflage resin coating material.

[0051] In order to further verify the efficacy of the present invention, the inventors conducted the following specific experiments (the pigment slurries were all dark green):

[0052] The reason why the present invention adopts the pigment slurry with dark green camouflage effect is that its advantages are mainly reflected in its high degree of integration with the environment, reduction of reflection and strong visual concealment.

[0053] Specifically, one of the benefits of dark green camouflage is its high degree of integration with the environment. Dark green is similar in color to vegetation in the natural environment, blending well into natural backgrounds such as forests and grasslands, thereby reducing the chance of detection. Secondly, the benefits of dark green camouflage also include reduced reflections. Dark green paint can eliminate or reduce reflections on the surface of an object, allowing the camouflaged object to maintain low visibility in various lighting conditions, especially in strong light environments. Furthermore, dark green camouflage has the characteristic of strong visual concealment. By using dark green paint, the overall outline of the object can be disrupted, avoiding the formation of obvious target features.
