Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather, and specifically, to a high-temperature resistant artificial leather. Background Art

[0002] Artificial leather is a plastic product that imitates animal leather and is mainly used in industries such as clothing, luggage, and ball products. Its production usually uses fabric as the base and is coated with synthetic resin and various plastic additives. Artificial leather has a variety of colors and patterns, good wear resistance and waterproof performance, is not afraid of being eaten by insects, is not easy to mildew, is high-temperature resistant and inexpensive.

[0003] After retrieval, a Chinese patent with the publication number of CN217598009U discloses a high-temperature resistant artificial leather, which includes a base layer. One side surface of the base layer is fixedly compounded with a flame retardant layer, and one side surface of the flame retardant layer is fixedly compounded with a high-temperature resistant layer. The surface of the high-temperature resistant layer is provided with long strip barrier strips. The long strip combination strips are located on one side surface of the first high-temperature resistant layer. The other side surface of the base layer is fixedly compounded with a buffer layer, and one side surface of the buffer layer is fixedly compounded with a cotton yarn layer. The inside of the high-temperature resistant layer is fixedly compounded with a first reinforcing fiber, and the inside of the cotton yarn layer is fixedly compounded with a second reinforcing fiber. The surface of the first reinforcing fiber is fixedly wound with connecting fibers, and one end surface of the connecting fiber is wound around the surface of the second reinforcing fiber to form a three-dimensional grid structure, which can effectively improve the composite strength and avoid peeling and cracking, thus greatly improving the convenience and stability of use and ensuring the high-temperature resistant effect and structural strength.

[0004] There are some drawbacks in the existing devices during use. For example: the artificial leather in the above solution has high-temperature resistance on its surface. In actual use, it is found that the flame retardant property of this artificial leather is poor. The flame retardant property of the existing artificial leather is mainly reflected in its slow burning speed and extinguishing immediately when removed from the fire. Although it has certain flame retardant performance, the internal heat insulation and high-temperature resistance effect is not good, resulting in heat being easily transferred to the human skin during actual use and easily causing burns to the human skin.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Embodiment 1

[0021] As Figure 1 and Figure 2 shown, the present invention provides a technical solution: a high-temperature resistant artificial leather, including a base fabric layer 10, a PVC foam layer 11 is fixedly compounded on the upper surface of the base fabric layer 10, a high-temperature resistant layer 12 is fixedly compounded on the upper surface of the PVC foam layer 11, a flame retardant layer 13 is fixedly compounded on the upper surface of the high-temperature resistant layer 12, a heat insulation fiber layer 14 is fixedly compounded on the lower surface of the base fabric layer 10, and an auxiliary heat insulation structure for heat insulation is arranged between the PVC foam layer 11 and the flame retardant layer 13. In the specific use process, the base fabric layer 10 is used as the basic skeleton of the artificial leather to provide physical strength and stability. The PVC foam layer 11 forms a layer on the base fabric layer 10, which may be used to increase the thickness, softness and buffering of the material. The high-temperature resistant layer 12 is used to withstand high temperatures and protect the underlying materials from direct damage by heat sources. The flame retardant layer 13 provides fire protection on the outermost layer to prevent the material from igniting or spreading flames. The heat insulation fiber layer 14 is located below the base fabric layer 10 to provide additional heat insulation performance and prevent heat from passing through the material. The auxiliary heat insulation structure is located between the PVC foam layer 11 and the flame retardant layer 13 to enhance the overall heat insulation effect.

[0022] As an implementation manner in this embodiment, as Figure 2 and Figure 3 shown, the auxiliary heat insulation structure includes airbags 20 fixedly arranged in an array on the PVC foam layer 11. The cross-sections of the plurality of airbags 20 are semi-circular structures, and the plurality of airbags 20 are filled with air inside. In this way, the airbags 20 will automatically expand when heated. A plurality of perforations 21 are arranged in an array on the high-temperature resistant layer 12, and a plurality of accommodation cavities 22 adapted to the airbags 20 are arranged in an array on the lower end surface of the flame retardant layer 13. The airbags 20 pass through the perforations 21 and are accommodated in the accommodation cavities 22. In the specific use process, when the airbags 20 are heated by the heat on the flame retardant layer 13, they will quickly expand. In this way, the airbags 20 pass through the perforations 21 and push up the flame retardant layer 13, and the top ends of the airbags 20 continue to expand and enlarge in the accommodation cavities 22. As a result, the flame retardant layer 13 and the high-temperature resistant layer 12 are separated. In this way, a certain space interval is formed between the flame retardant layer 13 and the high-temperature resistant layer 12, which can, to a certain extent, prevent the heat on the flame retardant layer 13 from being transferred to the high-temperature resistant layer 12 and play a certain heat insulation effect.

[0023] Among them, the base fabric layer 10 is a bamboo carbon fiber cloth, which has the characteristics of moisture absorption and breathability, antibacterial and antimicrobial, warm in winter and cool in summer, green and environmental protection. This material not only has high temperature resistance but also provides physical strength and stability for the artificial leather. The high-temperature resistant layer 12 is made of a polyester resin reinforced composite material, which has the advantages of excellent high-temperature resistance, high mechanical properties and good corrosion resistance. The flame retardant layer 13 is made of tinfoil cloth and is positioned by hot pressing and compounding, and has excellent heat insulation, heat radiation reflection and fire prevention properties. The heat insulation fiber layer 14 is made of glass fiber and has excellent heat insulation, heat resistance and electrical insulation properties.

[0024] Working principle: First, the base fabric layer 10 serves as the basic framework of the artificial leather, providing physical strength and stability. The PVC foam layer 11 is formed on the base fabric layer 10 and may be used to increase the thickness, softness and buffering of the material. The high-temperature resistant layer 12 is used to withstand high temperatures and protect the underlying materials from direct damage by heat sources. The flame retardant layer 13 provides fire protection on the outermost layer to prevent the material from igniting or spreading flames. The heat insulation fiber layer 14 is located below the base fabric layer 10 to provide additional heat insulation performance and prevent heat from passing through the material. The auxiliary heat insulation structure is located between the PVC foam layer 11 and the flame retardant layer 13 to enhance the overall heat insulation effect. When in use, when the airbag 20 receives heat on the flame retardant layer 13, it will expand rapidly. Thus, the airbag 20 passes through the perforation 21 and pushes up the flame retardant layer 13, and the top of the airbag 20 continues to expand and enlarge within the accommodating cavity 22, thereby separating the flame retardant layer 13 from the high-temperature resistant layer 12. In this way, a certain spatial interval is formed between the flame retardant layer 13 and the high-temperature resistant layer, which can, to a certain extent, prevent the heat on the flame retardant layer 13 from being transferred to the high-temperature resistant layer 12, achieving a certain heat insulation effect.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
