Description

Technical Field

[0001] This invention relates to the technical field of upholstered furniture, specifically to a flame-retardant and heat-insulating multi-layer composite cladding board for upholstered furniture. Background Technology

[0002] Upholstered furniture refers to furniture primarily made of soft materials such as sponge and fabric, mainly including sofas, mattresses, upholstered chairs, headboards, etc., and is one of the most widely used furniture categories in modern home life and public spaces. Among them, flexible polyurethane foam, due to its excellent properties such as low density, high specific strength, good elasticity, sound absorption, and breathability, is widely used as a cushioning filling material for upholstered furniture. For example, a paint-free, melamine-free, environmentally friendly coated board with announcement number CN204725968U includes a substrate, the outer surface of which is covered with a 360° outer decorative layer. The outer decorative layer includes a base layer and a decorative layer. The base layer has a multi-layer kraft paper structure, and both the base layer and the decorative layer have a phenolic resin layer on their outer surfaces, which are fixed together by the phenolic resin layer. This type of board features a simple structure, reasonable design, stable color, effectively solving fading and color difference problems, high hardness, good wear resistance, good transparency, resistance to edge chipping, and strong overall integrity. For example, a melamine-coated board with announcement number CN218615760U belongs to the field of furniture technology. It consists of a flat panel, a melamine panel, and a melamine multilayer board. The melamine multilayer board has grooves on both sides, the distance of which from the grooves to the edges of the board is determined by the thickness of the flat panel. The flat panel is a semi-finished product; after being bent through the grooves, the melamine multilayer board forms a U-shape. The flat panel is then covered by this U-shaped melamine multilayer board, with one side of the flat panel connected to the melamine panel. This design avoids edge defects, and the U-shaped covering significantly reduces production costs. The seamless, one-piece covering results in a more refined appearance. However, the aforementioned coated board still has the following drawbacks in actual use: 1. Traditional veneer panels have poor compressive strength. Since veneer panels are usually used in sofa and bed cushions and other places that are frequently subjected to pressure, they are prone to deformation after being subjected to pressure for a long time, and their recovery ability will be reduced. 2. Furthermore, the cladding panels usually have flame-retardant materials inside for fire protection. However, traditional flame-retardant materials have limited flame-retardant effects and do not have the function of extinguishing fires after a fire. Some cladding panels are filled with flame retardants, but their release rate after a fire is slow, which still affects fire extinguishing.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on the existing covering panels. Summary of the Invention

[0004] The purpose of this invention is to provide a flame-retardant and heat-insulating multi-layer composite cladding board for upholstered furniture, in order to solve the problems mentioned in the background art, that traditional cladding boards have poor compressive strength and that traditional flame-retardant materials have limited flame-retardant effects and do not have the function of extinguishing fires after a fire.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flame-retardant and heat-insulating multi-layer composite cladding board for upholstered furniture, comprising a surface layer, wherein the surface layer covers the exterior of the entire flame-retardant layer, the upper substrate, the lower substrate, and the moisture-proof layer; It also includes: a flame-retardant layer disposed on the inner side of the surface finish layer, an upper substrate attached to the lower end surface of the flame-retardant layer, a buffer mechanism disposed between the upper substrate and the lower substrate, and a moisture-proof layer attached to the lower end surface of the lower substrate.

[0006] Preferably, the moisture-proof layer is made of EPDM rubber. The rubber moisture-proof layer not only has a good moisture-proof effect, but also improves the anti-slip properties of the back of the cover plate.

[0007] Preferably, the upper substrate has through-holes that are evenly distributed. The presence of these holes does not impede the strength of the upper substrate, reduces the overall weight of the covering plate, and facilitates the passage of flame-retardant liquid.

[0008] Preferably, the buffer mechanism is used to improve the overall resilience of the covering plate, and the buffer mechanism includes a buffer bladder disposed between the upper substrate and the lower substrate. By setting the buffer bladder, the overall compressive strength of the covering plate can be improved.

[0009] Preferably, the buffer bladder is filled with flame-retardant liquid, and the side of the buffer bladder near the upper substrate is wavy. By making the surface of the buffer bladder wavy, the cushioning performance can be further improved.

[0010] Preferably, a fixing block is provided at the corner of both the upper and lower substrates, and a spring is provided between the two sets of fixing blocks. The spring can also improve the buffering performance.

[0011] Preferably, the upper substrate and the lower substrate form a relatively elastic motion, and the upper and lower end faces of the buffer bladder are respectively attached to and connected to the upper substrate and the lower substrate.

[0012] Preferably, a shape memory alloy is fixed between the two fixing blocks, and the shape memory alloy is a nickel-titanium alloy wire material. The shape memory alloy can deform in the event of a fire, thereby compressing the buffer bag.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This flame-retardant and heat-insulating multi-layer composite cladding board for upholstered furniture, through the setting of multiple buffer structures, can improve the overall compressive strength of the cladding board and ensure good recovery ability even after long-term pressure. Furthermore, by using built-in flame retardants, it can be quickly released in the event of a fire to achieve the effect of extinguishing the fire. The specific details are as follows: 1. Through the design of the buffer bladder and spring, both have good recovery performance, so they can rebound quickly after being squeezed, ensuring the elasticity of the covering plate and preventing it from being easily deformed or damaged. Furthermore, the buffer bladder is designed with a wave shape near the upper substrate, which further enhances the rebound performance. 2. After the buffer bladder is burned, the flame-retardant liquid inside can be discharged to extinguish the fire. The shape memory alloy 8 deforms into a bent shape when heated, which can drive the upper and lower substrates to move closer to each other, thereby squeezing the buffer bladder. In this way, the flame-retardant liquid inside can be quickly discharged through the fixing hole, achieving a good fire extinguishing effect. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-8The present invention provides the following technical solution: Example 1: In order to solve the problems existing in the prior art, this example provides the following technical solution: a flame-retardant and heat-insulating multi-layer composite cladding board for upholstered furniture, including a surface layer 1, which covers the entire flame-retardant layer 2, upper substrate 3, lower substrate 4 and moisture-proof layer 5; and further including: a flame-retardant layer 2, which is disposed on the inner side of the surface layer 1, with the upper substrate 3 pasted on the lower end surface of the flame-retardant layer 2, and a buffer mechanism provided between the upper substrate 3 and the lower substrate 4, and the moisture-proof layer 5 pasted on the lower end surface of the lower substrate 4.

[0018] Existing veneer panels have relatively poor compressive strength. Since veneer panels are typically used in sofa and bed cushions and other areas subject to frequent pressure, they are prone to deformation after prolonged pressure, resulting in reduced resilience. Figures 1-4 and Figures 6-7 As shown, the moisture-proof layer 5 is made of EPDM rubber; the buffer mechanism is used to improve the overall resilience of the covering plate, and the buffer mechanism includes a buffer bladder 9 disposed between the upper substrate 3 and the lower substrate 4; a fixing block 6 is provided at the corner of the upper substrate 3 and the lower substrate 4, and a spring 7 is provided between the two sets of fixing blocks 6; the upper substrate 3 and the lower substrate 4 form a relative elastic movement through the spring 7, and the upper and lower end faces of the buffer bladder 9 are respectively attached to the upper substrate 3 and the lower substrate 4; by setting the buffer bladder 9 and the spring 7 between the upper substrate 3 and the lower substrate 4, the covering plate can drive the buffer bladder 9 and the spring 7 to deform after being squeezed. Since both have good recovery performance, they can quickly rebound after being squeezed, ensuring the elasticity of the covering plate and preventing it from easily deforming and being damaged. The compression of the upper substrate 3 is not enough to cause the buffer bladder 9 to rupture, thus ensuring safety.

[0019] Example 2: While cladding panels typically incorporate flame-retardant materials for fire protection, traditional flame-retardant materials have limited effectiveness and do not provide fire extinguishing capabilities after a fire. Some cladding panels are filled with flame retardants, but their release rate after a fire is slow, still affecting fire suppression. Therefore, this example employs the following technical solution: Figures 3-5 and Figures 7-8 As shown, the upper substrate 3 has through-holes 31 inside, and the holes 31 are evenly distributed; the buffer bladder 9 is filled with flame-retardant liquid, and the side of the buffer bladder 9 near the upper substrate 3 is wavy; a shape memory alloy 8 is fixed between the two fixing blocks 6, and the shape memory alloy 8 is made of nickel-titanium alloy wire; when the covering plate encounters a fire, the flames burn through the surface layer 1 and the flame-retardant layer 2, and then burn through the buffer bladder 9, allowing the flame-retardant liquid inside to be discharged for fire extinguishing. At the same time, the shape memory alloy 8 deforms under heat and bends, which can drive the upper substrate 3 and the lower substrate 4 to move closer to each other, thereby squeezing the buffer bladder 9. In this way, the flame-retardant liquid inside can be quickly discharged through the fixing holes 31, achieving a good fire extinguishing effect and improving safety.
