Description

Technical Field

[0001] This utility model relates to the field of composite fabric technology, and in particular to a flame-retardant and heat-insulating high-temperature coated fabric. Background Technology

[0002] Flame-retardant and heat-insulating fabrics are widely used in many fields, one important function being the manufacture of fire-fighting suits. They are also widely used in industries involving high-temperature operations, such as steel, metallurgy, welding, power, and petrochemicals. Traditional coated fabrics are bonded together by hot pressing or adhesive, resulting in a weak interlayer structure that often leads to problems like peeling, cracking, or insufficient high-temperature resistance. Therefore, designing a coated fabric that simultaneously satisfies flame retardancy, heat insulation, and high-temperature rupture resistance is of significant technical importance. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a flame-retardant and heat-insulating high-temperature coated fabric, which more precisely solves the problems described above.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a flame-retardant and heat-insulating high-temperature coated fabric, including a high-temperature resistant fabric body. The high-temperature resistant fabric body is composed of a first fireproof layer, a heat insulation layer, a second fireproof layer, and a fabric inner layer, which are bonded together by adhesive bonding. The heat insulation layer is disposed between the first fireproof layer and the heat insulation layer. The fabric inner layer is disposed in close contact with the lower surface of the second fireproof layer. The upper surface of the first fireproof layer is provided with a flame-retardant coating. The heat insulation layer is wavy, which folds the fabric layer. The flame-retardant gap formed between the heat insulation layer and the first and second fireproof layers is filled with a carbon fiber cotton filling layer.

[0006] Furthermore, the first fireproof layer is formed by weaving an upper layer of high-temperature resistant limiting warp, a lower layer of high-temperature resistant limiting warp, and a high-temperature resistant limiting weft. The upper layer of high-temperature resistant limiting warp forms a line node on the upper surface of the first fireproof layer, and the lower layer of high-temperature resistant limiting warp forms a line node on the lower surface of the first fireproof layer. The second fireproof layer has the same weaving structure as the first fireproof layer.

[0007] Furthermore, the corrugated section of the heat insulation layer is provided with expandable microspheres, which are any one or more composites of polypropylene porous microspheres, polyethylene porous microspheres, and silicone porous microspheres.

[0008] Furthermore, the inner layer of the fabric is composed of a composite weave of nylon limiting yarn and carbon fiber yarn, and the weave method is a flat staggered stitch weave.

[0009] Furthermore, the first fireproof layer, the heat insulation layer, and the second fireproof layer are connected by fiberglass stitching, which is diamond-shaped.

[0010] Furthermore, the surfaces of the first fireproof layer, the heat insulation layer, the second fireproof layer, the inner fabric layer, and the flame-retardant coating are incorporating micro-anchoring particles, which are any one or more composites of silica microspheres, silicate microspheres, and polyester particles.

[0011] Furthermore, the surface of the flame-retardant coating is provided with biomimetic patterns, which are any one or more combinations of fish scale patterns, crustal patterns, or petal patterns.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses lines to create nodes on the surfaces of the first and second fireproof layers. The raised nodes are bonded to the double-bonded thermoplastic adhesive layer between the layers, ensuring a strong connection between the layers and greatly avoiding delamination and cracking. The high-temperature resistant fabric body has a flame-retardant coating that exhibits good thermal stability at high temperatures and has high thermal conductivity, which can effectively reduce body heat loss and greatly improve the flame retardant and heat insulation performance of the fabric. The flame-retardant coating surface can be set with biomimetic textures according to actual needs to improve lateral support, bending resistance, tear resistance, waterproofing, abrasion resistance, flexibility and tensile strength.

[0014] 2. In this utility model, the heat insulation layer is a wavy folded fabric layer, and an expansion microsphere is provided in the wavy bend of the heat insulation layer. When the expansion microsphere is subjected to high temperature, it expands, causing the wavy bend of the heat insulation layer to bulge, thereby greatly improving the heat insulation and flame retardant performance by separating the first fireproof layer and the second fireproof layer.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1 As shown, a flame-retardant and heat-insulating high-temperature coated fabric includes a high-temperature resistant fabric body 1. The high-temperature resistant fabric body 1 is composed of a first fireproof layer 101, a heat insulation layer 102, a second fireproof layer 103, and a fabric inner layer 104, which are bonded together with a double-bonded thermoplastic adhesive layer to prevent the interlayer bonding from peeling and cracking. The heat insulation layer 102 is disposed between the first fireproof layer 101 and the heat insulation layer 102. The fabric inner layer 104 is disposed close to the lower surface of the second fireproof layer 103. The upper surface of the first fireproof layer 101 is provided with a flame-retardant coating 105, such as... Figure 3 As shown, the first fireproof layer 101 is formed by warp and weft weaving of the upper high-temperature resistant limiting warp 1011, the lower high-temperature resistant limiting warp 1012, and the high-temperature resistant limiting weft 1013. The upper high-temperature resistant limiting warp 1011 forms a line node 1014 on the upper surface of the first fireproof layer 101 through the hook thread, and the lower high-temperature resistant limiting warp 1012 forms a line node 1014 on the lower surface of the first fireproof layer 101 through the hook thread. The second fireproof layer 103 has the same weaving structure as the first fireproof layer 101. The line node 1014 protrudes and is bonded to the double-bonded thermoplastic adhesive layer to ensure a firm connection between the layers and greatly avoid delamination and cracking.

[0022] The surfaces of the first fireproof layer 101, the heat insulation layer 102, the second fireproof layer 103, the inner fabric layer 104, and the flame-retardant coating 105 are incorporating micro-anchoring particles. These micro-anchoring particles are any one or more composites of silica microspheres, silicate microspheres, and polyester particles, forming a stable connection through mechanical interweaving. This maintains the relative independence of the materials at high temperatures while providing limited force conduction. The flame-retardant coating 105 is any one of a neoprene coating, a polyethylene coating, or a polypropylene coating. The flame-retardant coating 105 exhibits good thermal stability at high temperatures and has high thermal conductivity, effectively reducing body heat loss and significantly improving the flame retardancy and heat insulation of the fabric. The flame-retardant coating 105 has a biomimetic texture 1051 on its surface. The biomimetic texture 1051 can be any one or more combinations of fish scale pattern, earth crust pattern or petal pattern. Fish scale pattern enhances the lateral support of the fabric, improves bending resistance, and increases the durability of the material. Earth crust pattern can disperse tensile force, enhance the tear resistance of the fabric, and improve the waterproof and abrasion resistance of the material. Petal pattern improves the flexibility and tensile strength of the fabric, and enhances the texture and aesthetics of the material surface.

[0023] The inner layer 104 of the fabric is made of a composite weave of nylon limiting yarn and carbon fiber yarn. The weave method is a flat staggered knit, which can improve water absorption. If it is used as a fabric that comes into contact with the skin, the inner layer 104 of the fabric can greatly improve comfort.

[0024] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: This utility model uses line nodes 1014 to outline the surfaces of the first fireproof layer 101 and the second fireproof layer 103. The protruding line nodes 1014 are bonded to the interlayer double-bond thermoplastic adhesive layer, ensuring a strong connection between layers and greatly avoiding delamination and cracking. A flame-retardant coating 105 is provided on the surface of the high-temperature resistant fabric body, exhibiting good thermal stability and high thermal conductivity at high temperatures, effectively reducing heat loss and greatly improving the flame-retardant and heat-insulating properties of the fabric. The surface of the flame-retardant coating 105 can be designed with biomimetic textures 1051 according to actual needs, improving lateral support, bending resistance, tear resistance, waterproofing, abrasion resistance, flexibility, and tensile strength.

[0025] Example 2

[0026] like Figure 2As shown, the heat insulation layer 102 is a wavy folded fabric layer. The flame-retardant gap 1021 formed between the heat insulation layer 102 and the first fireproof layer 101 and the second fireproof layer 103 is filled with a carbon fiber cotton layer to further improve the flame-retardant and heat-insulating performance. The wavy bending part of the heat insulation layer 102 is provided with expandable microspheres 1022. The expandable microspheres 1022 are any one or more composites of polypropylene porous microspheres, polyethylene porous microspheres, and silicone porous microspheres. When the expandable microspheres 1022 are subjected to high temperature, they expand, causing the wavy bending part of the heat insulation layer 102 to bulge, thereby separating the first fireproof layer 101 and the second fireproof layer 103 and greatly improving the heat insulation and flame-retardant performance.

[0027] The first fireproof layer 101, the heat insulation layer 102, and the second fireproof layer 103 are connected by a glass fiber suture 106. The glass fiber suture 106 is a diamond-shaped suture, which satisfies the stability of the interlayer structural connection and can also satisfy the structural deformation when the heat insulation layer 102 is heated and expanded.

[0028] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: In this utility model, the heat insulation layer 102 is a wavy folded fabric layer, and an expansion microsphere 1022 is provided in the wavy bending part of the heat insulation layer 102. When the expansion microsphere 1022 is subjected to high temperature, it expands, causing the wavy bending part of the heat insulation layer 102 to bulge, thereby greatly improving the heat insulation and flame retardant performance by separating the first fireproof layer 101 and the second fireproof layer 103.

[0029] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
