Description

Technical Field

[0001] The utility model relates to the technical field of composite mesh cloth, in particular to a multi-layer composite mesh cloth with high structural strength. Background Art

[0002] Mesh is a mesh material made of glass fiber, typically using medium-alkali or alkali-free glass fiber yarn. This material is woven using a special weave structure (such as a leno weave) and coated with an alkali-resistant polymer emulsion to enhance its alkali resistance, strength, and durability. However, existing meshes are often exposed to harsh environments in practical applications, which can lead to a reduction in structural strength. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and to provide a multi-layer composite mesh with high structural strength, which can improve the situation that the structural strength of the existing mesh is reduced when used in harsh environments.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] Technical Solution 1: A multi-layer composite mesh with high structural strength, characterized in that, from top to bottom, a first tensile layer, a protective layer, a reinforcing layer and a second tensile layer are provided in sequence; the first tensile layer and the second tensile layer are welded by stainless steel wire to form a grid shape; the protective layer is formed by weaving aramid fiber through a twisted heald process, and is sewn and fixed to the first tensile layer; the reinforcing layer is formed by weaving glass fiber through a twisted heald process, and is sewn and fixed to the protective layer and the second tensile layer.

[0006] Technical solution 2 based on technical solution 1: a fireproof layer is provided on the upper side of the first tensile layer, and the fireproof layer is woven from aluminum silicate fibers.

[0007] Technical solution three based on technical solution two: a waterproof layer is provided on the upper side of the fireproof layer, and the waterproof layer is formed by weaving polyurethane fibers.

[0008] Technical solution 4 based on technical solution 3: an antistatic layer is provided on the lower side of the second tensile layer, and the antistatic layer is woven from nylon fibers containing carbon black.

[0009] Technical solution five based on technical solution four: the lower surface of the antistatic layer is coated with a rubber coating, and the rubber coating is made of EPDM rubber.

[0010] Technical solution six based on technical solution five: a wear-resistant layer is provided on the upper surface of the waterproof layer, and the wear-resistant layer is formed by weaving nylon fibers.

[0011] Technical solution seven based on technical solution six: the first tensile layer and the second tensile layer are made of stainless steel wire with a tensile strength of 800MPa to 1000MPa.

[0012] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0013] Technical Solution 1 provides a multi-layer composite mesh with high structural strength. The mesh is provided with two tensile layers, and a protective layer and a reinforcement layer are provided between the two tensile layers. The two tensile layers are welded into a grid shape by stainless steel wire. The stainless steel wire has extremely high tensile strength, and the small-diameter stainless steel wire has good flexibility, which facilitates the rolling, storage and unfolding of the mesh. The tensile layers are arranged above and below the protective layer and the reinforcement layer, so that the tensile layers can serve as the main body of the mesh, provide the mesh with excellent tensile properties, and improve the overall structural strength and durability of the mesh. In addition, a protective layer is provided, which is formed by weaving aramid fiber heddles. The heddling process combined with aramid fiber makes the protective layer have extremely high tensile strength, and the protective layer is arranged between the reinforcement layer and the first tensile layer to provide protection for the outer side of the reinforcement layer. A reinforcement layer formed by weaving glass fiber heddles is provided. The glass fiber has excellent structural strength and heat resistance. In combination with the protective layer and the two tensile layers, the overall strength and durability of the mesh are further improved. In harsh environments, it can still maintain a high strength after long-term use.

[0014] In the second technical solution, aluminum silicate fibers are woven to form a fireproof layer, providing fireproof protection for the inner tensile layer, protective layer and reinforcement layer.

[0015] In technical solution three, polyurethane fibers are woven to form a waterproof layer. The waterproof properties of polyurethane fibers prevent the mesh from absorbing water in humid or watery environments, thereby maintaining its structural strength and durability and avoiding the degradation of material performance due to water intrusion.

[0016] In technical solution four, an anti-static layer is set up, and the nylon fiber containing carbon black can effectively prevent the accumulation of static electricity and avoid the impact of static electricity on the performance of the mesh, while maintaining the mechanical strength and durability of the mesh.

[0017] In technical solution five, the EPDM rubber coating provides additional protection for the mesh, further improving the durability of the mesh.

[0018] In technical solution six, a wear-resistant layer is set on the upper side of the waterproof layer. The wear-resistant layer is woven with nylon fibers, which improves the wear resistance of the mesh and thus extends the service life of the mesh in harsh environments.

[0019] In technical solution seven, stainless steel wire with high tensile strength is used as the material of the tensile layer, so that the mesh can withstand greater mechanical stress and ensure that the mesh has high structural strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example

[0032] The utility model provides a multi-layer composite mesh with high structural strength. Figure 1 and Figure 2 From top to bottom, that is, from the outside to the inside of the mesh, the mesh is sequentially provided with a wear-resistant layer 8, a waterproof layer 2, a fireproof layer 3, a first tensile layer, a protective layer 4, a reinforcing layer 1, a second tensile layer, an antistatic layer 7 and a rubber coating 5.

[0033] Among them, reference Figure 2 The first tensile layer and the second tensile layer are welded by stainless steel wire to form a grid; the protective layer 4 is formed by weaving aramid fiber through a twisting process, and is sewn and fixed to the first tensile layer; the reinforcing layer 1 is formed by weaving glass fiber through a twisting process, and is sewn and fixed to the protective layer 4 and the second tensile layer.

[0034] Specifically, refer to Figure 3, which shows a metal mesh 6 with a grid structure formed by welding stainless steel wire, and the metal mesh 6 forms the above-mentioned first tensile layer and second tensile layer. The tensile strength of the stainless steel wire used in this embodiment is 800MPa to 1000MPa. Stainless steel wire has high tensile strength and corrosion resistance. At the same time, the grid structure formed allows the mesh to effectively disperse stress when subjected to tension, avoiding local excessive force and causing breakage. Therefore, after long-term use, the mesh can still maintain a high structural strength to meet actual use requirements. It should be noted that the stainless steel used in the metal mesh 6 is not limited to any model, as long as it is stainless steel and has high-quality rust-proof properties.

[0035] Between the first and second tensile layers are a protective layer 4 and a reinforcement layer 1. The protective layer 4 is woven from a twisted heald of aramid fibers, which possesses exceptional strength and heat resistance, is resistant to breakage, and remains stable in high-temperature environments. The protective layer 4 is sewn and secured to the first tensile layer, ensuring a secure attachment and enhancing the overall structural stability and durability. The reinforcement layer 1 is woven from a twisted heald of glass fibers, which also possesses high strength and heat resistance, remaining stable in harsh environments and providing the mesh with enhanced tensile strength and durability.

[0036] Furthermore, the aforementioned first tensile layer, second tensile layer, protective layer 4, and reinforcement layer 1 constitute the main body of the multi-layer composite mesh. Each layer in this multi-layer structural design contributes to the overall structural strength. The first and second tensile layers provide basic tensile strength, while the protective layer 4 and reinforcement layer 1 provide additional mechanical support and protection, enabling the mesh to maintain high strength and stability in various application scenarios. The tensile layer is provided in two layers, located above and below the protective layer 4 and reinforcement layer 1, respectively, to protect these two layers.

[0037] Reference Figure 2 , a fireproof layer 3 is also provided on the upper side of the first tensile layer, and the fireproof layer 3 is woven from aluminum silicate fibers. Aluminum silicate fibers have very high temperature resistance and can withstand temperatures of up to 1000°C or above. When encountering flames or high temperatures, aluminum silicate fibers can effectively insulate heat and prevent the fire source from penetrating into the interior of the composite mesh, thereby protecting the internal structure from damage by high temperatures. Due to the low thermal conductivity of aluminum silicate fibers, the fireproof layer 3 can serve as an effective thermal insulation barrier, reducing heat transfer to the interior of the composite mesh and lowering the internal temperature. Aluminum silicate fibers have good chemical stability and are not easily corroded by most chemicals, which increases the durability and service life of the fireproof layer 3. The fireproof layer 3 is woven from aluminum silicate fibers, and this woven structure can provide sufficient strength and stability while also maintaining good softness and foldability.

[0038] Reference Figure 2 A waterproof layer 2 is placed above the fireproof layer 3. This layer is woven from polyurethane fibers. Polyurethane fibers are hydrophobic, meaning they are not easily absorbed by the fibers. Therefore, the waterproof layer 2, woven from polyurethane fibers, effectively blocks moisture penetration, protecting the composite mesh's internal structure from the effects of humid environments. Furthermore, polyurethane fibers possess excellent wear resistance, resisting external friction and abrasion, thereby extending the service life of the waterproof layer 2.

[0039] Reference Figure 2 A wear-resistant layer 8 is provided on the upper side of the waterproof layer 2. The wear-resistant layer 8 is woven from nylon fibers. Nylon fibers have excellent wear resistance. The wear-resistant layer 8 can be sewn together with the waterproof layer 2 to improve the overall wear resistance of the mesh.

[0040] Reference Figure 2 An antistatic layer 7 is provided beneath the second tensile layer. This layer is woven from nylon fibers containing carbon black. Carbon black, a conductive material, imparts conductivity to nylon fibers, effectively directing static charge from the surface of the composite mesh toward the ground or other grounded objects, thereby preventing static charge accumulation and reducing safety hazards. The antistatic layer 7 prevents static electricity from building up within the metal mesh 6, ensuring safety.

[0041] Reference Figure 2 The underside of the antistatic layer 7 is coated with a rubber coating 5 made of EPDM rubber. EPDM rubber has excellent weather resistance, maintaining its performance in extreme weather conditions and preventing aging and deterioration of the coating. Furthermore, EPDM rubber has excellent wear resistance and water resistance, reducing the effects of external friction and water vapor penetration on the composite mesh, thereby extending its service life. The rubber coating 5 can be applied to the underside of the antistatic layer 7 by spraying, roller coating, or other methods.

[0042] The embodiment of the utility model provides a multi-layer composite mesh with high structural strength. The mesh is provided with two tensile layers, and a protective layer 4 and a reinforcement layer 1 are provided between the two tensile layers. The two tensile layers are welded by stainless steel wire to form a grid. The stainless steel wire has extremely high tensile strength, and the small diameter stainless steel wire has good flexibility, which is convenient for the mesh to be rolled up, stored and unfolded. The tensile layer is provided above and below the protective layer 4 and the reinforcement layer 1, so that the tensile layer can be used as the main body of the mesh, providing the mesh with excellent tensile performance, thereby improving the overall structural strength and durability of the mesh. In addition, a protective layer 4 is provided, which is formed by weaving aramid fiber twisted healds. The twisted heald process is combined with the aramid fiber to make the protective layer 4 have extremely high tensile strength, and the protective layer 4 is arranged between the reinforcing layer 1 and the first tensile layer, which can provide protection for the outer side of the reinforcing layer 1; a reinforcing layer 1 is provided which is formed by weaving glass fiber twisted healds. The glass fiber has excellent structural strength and heat resistance, and is combined with the protective layer 4 and the two tensile layers to further improve the overall strength and durability of the mesh. In harsh environments, it can still maintain high strength after long-term use.

Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
