Description

Technical Field

[0001] This utility model relates to the field of carpets, specifically to a carpet with fire-resistant function. Background Technology

[0002] Carpets are typically made from natural fibers such as cotton, linen, wool, silk, and grass, or synthetic fibers, through hand or machine weaving, tufting, or spinning. However, natural and synthetic fibers are generally flammable and can easily contribute to the spread of fire. An existing fire-resistant carpet (publication number CN209346598U) incorporates basalt fiber fire-retardant cloth, a flame-retardant layer, silicone rubber-coated fiberglass cloth, and a surface layer, giving it excellent fire-resistant and heat-insulating properties. However, its complex structure with numerous layers makes manufacturing complicated, and the carpet is also quite thick. Therefore, this invention proposes a carpet with a simple structure, high comfort, and fire-resistant function. Utility Model Content

[0003] This invention provides a fire-resistant carpet, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A fire-resistant carpet includes a backing fabric and pile on the backing fabric;

[0006] A thin adhesive layer is also provided on the back of the base fabric. The thickness of the thin adhesive layer is less than the length of the pile passing through the base fabric. A first solid fire-retardant particle is also provided on the lower side of the thin adhesive layer. The first solid fire-retardant particle is distributed between adjacent piles and is in direct contact with the adjacent piles. The upper surfaces of the base fabric and the piles are also coated with fire-retardant adhesive. A buffer layer is also provided on the lower end face of the piles. A base layer for bonding with the bottom surface is also provided below the buffer layer.

[0007] As a further improvement, the first solid fireproof particles are arranged in multiple lines, and the multiple lines intersect to form a grid.

[0008] As a further improvement, the first solid fire-retardant particle is made of composite material particles.

[0009] As a further improvement, the base layer is made of polyester adhesive and is also embedded with a mesh.

[0010] As a further improvement, specifically, the lines of the first solid fireproof particles are arranged to intersect to form several squares, wherein the side length of the square is X, and 1cm≤X≤3cm.

[0011] As a further improvement, a layer of basalt fiber fireproof cloth is provided between the buffer layer and the base layer.

[0012] As a further improvement, the lower side of the base layer is also provided with anti-slip protrusions.

[0013] The beneficial effects of this utility model are:

[0014] By setting a thin adhesive layer and first solid fire-retardant particles on the back of the backing fabric, and applying fire-retardant adhesive to the surface of the backing fabric and pile, and setting a buffer layer and base layer on the lower end of the pile, the structure is simplified. In particular, placing the first solid fire-retardant particles between adjacent piles effectively reduces the thickness of the carpet and also reduces the foreign object feeling caused by the first solid fire-retardant particles when walking or stepping on them, making the overall feel softer. The fire-retardant adhesive applied to the surface of the backing fabric and pile forms the first fire-retardant measure. When the pile is ignited, it continues to burn downwards until it passes through the backing fabric, where it can quickly transfer heat to the first solid fire-retardant particles between adjacent piles. This causes the fire-retardant particles to react quickly when heated and volatilize substances that inhibit combustion, thus forming an effective fire-retardant effect. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0023] Example 1:

[0024] Reference Figure 1-2 As shown, a fire-retardant carpet includes a backing fabric 3 and pile 1 embedded in the backing fabric 3. A thin adhesive layer 4 is also provided on the back of the backing fabric 3. The thickness of the thin adhesive layer 4 is less than the length of the pile 1 passing through the backing fabric 3. First solid fire-retardant particles 6 are also provided on the underside of the thin adhesive layer 4. The first solid fire-retardant particles 6 are distributed between adjacent piles 1, and their diameter is between 0.5-2 mm, depending on the spacing of the pile 1 on the carpet. Different carpets have different spacing of the pile 1. The side of the pile 1 that passes through the backing fabric 3 is provided with the thin adhesive layer 4, except for the thick portion of the thin adhesive layer 4. When the first solid fire-retardant particles 6 are placed between the piles 1, they are in direct contact with adjacent piles 1. When the pile 1 is ignited, the portion passing through the backing fabric 3 can more quickly transfer heat. The first solid fire-retardant particles 6 react with heat to release substances that can prevent combustion and thus have a flame-retardant effect. The thin adhesive layer 4 can prevent the first solid fire-retardant particles 6 from falling out from the holes in the base fabric 3 or the gaps between the holes and the pile 1. The base fabric 3 and the upper surface of the pile 1 are also coated with fire-retardant adhesive 2, forming the first fire-retardant measure. The lower end of the pile 1 is also provided with a cushioning layer 5, which is made of polyurethane. Polyurethane has high strength, tear resistance, wear resistance, and good heat insulation and waterproof performance. It has high sound absorption, heat insulation and insulation effects, and excellent elasticity, which can reduce the foreign object feeling caused by the first solid fire-retardant particles 6 when stepped on, thereby increasing the comfort of the carpet. Below the cushioning layer 5, there is also a base layer 7 for bonding with the bottom surface.

[0025] It should be noted that placing the first solid fire-retardant particles 6 between adjacent piles 1 can reduce the thickness of the carpet. Furthermore, during walking or stepping, because the first solid fire-retardant particles 6 are located between the piles 1, the piles 1 will flatten when squeezed, filling the gaps between adjacent piles 1, but not completely. There will still be gaps between the piles 1 on the upper surface of the backing fabric 3. In addition, the piles 1 themselves have a certain degree of softness and resilience, which can prevent them from being squeezed with the first solid fire-retardant particles 6 in the vertical direction. This can reduce the foreign object feeling at the bottom when walking or stepping, making the overall feel softer, the structure simpler, and the manufacturing process more convenient, which helps to improve production efficiency.

[0026] Specifically, the first solid fireproof particles 6 are arranged in lines, and multiple lines intersect to form a grid, which reduces the density of the first solid fireproof particles 6 per unit area, making the carpet softer overall and improving the feel underfoot.

[0027] More specifically, the first solid fireproof particles 6 are arranged in a series of intersecting lines to form several squares, where the side length of the square is X, and 1cm≤X≤3cm. The size is set according to the size of an adult's foot. When the side length X is less than 1cm, the density is higher and the foot feels harder. When it is greater than 3cm, there is a large gap in the middle of the square, which is easy to cause a concave foot feel and its flame retardant effect is poor.

[0028] Specifically, the first solid fire-retardant particle 6 uses composite material particles, which have better performance than ordinary single-material particles, including but not limited to magnesium hydroxide-aluminum hydroxide composite particles. The thermal decomposition temperature of magnesium hydroxide is 340-490℃, and the decomposition temperature of aluminum hydroxide is around 180-200℃. During combustion, aluminum hydroxide decomposes first, absorbing heat and releasing water vapor, which plays a preliminary role in flame retardancy and cooling. As the temperature rises, magnesium hydroxide decomposes again, further absorbing a large amount of heat and releasing more water vapor, thereby achieving a better flame retardant effect.

[0029] Specifically, a layer of basalt fiber fireproof cloth 10 is provided between the buffer layer 5 and the base layer 7, which can effectively block the downward transfer of heat and is suitable for carpets laid on wooden floors.

[0030] Specifically, the base layer 7 uses polyester adhesive and is also embedded with mesh 9, which can effectively prevent the base layer 7 from being excessively deformed or torn when subjected to external forces.

[0031] Specifically, the underside of the base layer 7 is also equipped with anti-slip protrusions 8, so that even if water gets into the bottom of the carpet after use, it will not easily slip.

[0032] Example 2:

[0033] Unlike Embodiment 1, a second solid fire-retardant particle is also provided in the buffer layer 5. The second solid fire-retardant particle is uniformly mixed in the buffer layer 5, and the diameter of the second solid fire-retardant particle is smaller than that of the first solid fire-retardant particle, with a diameter of 0.1mm-0.2mm. The mixing ratio of the second solid fire-retardant particle and the material of the buffer layer 5 is 10%-15%, which can improve the fire-retardant effect when the carpet is ignited from the edge side, and has little impact on the overall softness of the carpet.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
