Description

Technical Field

[0001] This utility model relates to the field of foam technology, and in particular to a composite foam for home furnishing products. Background Technology

[0002] Composite foam is widely used in home furnishing products such as sofas, mattresses, carpets, and curtains to provide functions such as cushioning, heat insulation, sound insulation, and warmth retention. It is usually made of a combination of materials with different properties to meet the requirements of home furnishing products for comfort, functionality, and durability.

[0003] Traditional composite foams used in home furnishing products often have a relatively simple structure. While some composite foams have certain cushioning properties, their heat insulation and sound insulation effects are poor. Others, although they have good heat insulation properties, lack sufficient cushioning and moisture-proof capabilities. In addition, the existing composite foams are not tightly bonded to other materials, making them prone to delamination during use, which reduces the stability and reliability of the products. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing composite foam for home products has the disadvantages of insufficient performance and loose bonding. Therefore, we propose a composite foam for home products.

[0005] To achieve the above objectives, this application adopts the following technical solution: a composite foam for home furnishing products, comprising a surface layer, wherein a first functional layer, a buffer layer, a second functional layer and a bottom layer are sequentially disposed from top to bottom on the bottom of the surface layer, and the surface layer, the first functional layer, the buffer layer, the second functional layer and the bottom layer are laminated together by means of a hot melt adhesive film.

[0006] Preferably, the surface layer is an antibacterial and antifungal layer, which is made of a blend of nano-silver antibacterial fibers and polyester fibers, wherein the nano-silver antibacterial fibers are evenly distributed among the polyester fibers.

[0007] Preferably, the first functional layer is a heat insulation and sound insulation layer, which is composed of aerogel and polyurethane foam, wherein the aerogel is uniformly filled in the pores of the polyurethane foam.

[0008] Preferably, the buffer layer is a honeycomb-structured EVA foam, and the individual honeycomb cells of the honeycomb structure are interconnected.

[0009] Preferably, the second functional layer is a waterproof and moisture-proof layer, formed by coating the surface of XPE foam with a polyvinyl acetal resin coating. The polyvinyl acetal resin coating is dense and uniform, and can effectively block the penetration of moisture.

[0010] Preferably, the bottom layer is an anti-slip layer, which is formed by mixing and pressing rubber particles with hot melt adhesive, wherein the rubber particles are evenly distributed in the hot melt adhesive.

[0011] Preferably, the honeycomb structure of the buffer layer is filled with a phase change material, which is paraffin wax.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting up a surface layer, a first functional layer, a buffer layer, a second functional layer, and a bottom layer, functions such as antibacterial and mildew-proof, heat insulation and sound insulation, buffering, waterproofing and moisture-proofing, and anti-slip can be integrated into one, thereby meeting the multi-dimensional needs of comfort, safety, and hygiene in the home environment and comprehensively improving the user experience of home products. At the same time, the layers are laminated together by hot melt adhesive film, resulting in a tighter bond and effectively avoiding delamination, thus improving the quality and reliability of the product.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a composite foam for home furnishing products, including a surface layer 1. From top to bottom, the bottom of the surface layer 1 is sequentially provided with a first functional layer 2, a buffer layer 3, a second functional layer 4, and a bottom layer 5. The surface layer 1, the first functional layer 2, the buffer layer 3, the second functional layer 4, and the bottom layer 5 are laminated together using a hot melt adhesive film. Through the arrangement of the surface layer 1, the first functional layer 2, the buffer layer 3, the second functional layer 4, and the bottom layer 5, functions such as antibacterial and mildew-proofing, heat insulation and sound insulation, buffering, waterproofing and moisture-proofing, and anti-slip properties can be integrated into one unit. This can meet the multi-dimensional needs for comfort, safety, and hygiene in the home environment, comprehensively improving the user experience of home furnishing products. Simultaneously, the lamination between the layers using a hot melt adhesive film results in a tighter bond, effectively preventing delamination and improving the quality and reliability of the product.

[0021] Reference Figure 2 As shown in this embodiment: the surface layer 1 is an antibacterial and mildew-proof layer, which is made of a blend of nano-silver antibacterial fibers and polyester fibers. The nano-silver antibacterial fibers are evenly distributed between the polyester fibers. By setting the antibacterial and mildew-proof layer, the antibacterial properties of the nano-silver antibacterial fibers can effectively inhibit the growth of bacteria and mold, provide health protection for the home environment, and extend the service life of the composite foam.

[0022] Reference Figure 2 As shown in this embodiment: the first functional layer 2 is a heat insulation and sound insulation layer, which is composed of aerogel and polyurethane foam. The aerogel is uniformly filled in the pores of the polyurethane foam. By using aerogel and polyurethane foam to form a heat insulation and sound insulation layer, the low thermal conductivity of aerogel and the porous structure of polyurethane foam are combined, thereby improving the heat insulation and sound insulation effect and better meeting the needs of home for temperature regulation and a quiet environment.

[0023] Reference Figure 3 As shown in this embodiment: the buffer layer 3 is a honeycomb-structured EVA foam. Each honeycomb cell is interconnected. By designing the buffer layer 3 as a honeycomb structure, it can absorb energy more effectively when subjected to external impact, thereby providing better buffering performance, protecting household items and human safety, and having greater practicality.

[0024] Reference Figure 2 As shown in this embodiment: the second functional layer 4 is a waterproof and moisture-proof layer, which is formed by coating the surface of XPE foam with a polyvinyl acetal resin coating. The polyvinyl acetal resin coating is dense and uniform, which can effectively block the penetration of moisture. By combining the polyvinyl acetal resin coating with XPE foam, the waterproof and moisture-proof effect can be improved, and it can be applied to more humid home environments, such as kitchens and bathrooms.

[0025] Reference Figure 4As shown in this embodiment: the bottom layer 5 is an anti-slip layer, which is made by mixing and pressing rubber particles with hot melt adhesive. The rubber particles are evenly distributed in the hot melt adhesive. Through the design of the bottom layer 5, the composite foam is not easy to slip during use, which increases stability and is suitable for home products that need to be placed on a flat surface, such as cushions and foot mats.

[0026] Reference Figure 3 As shown in this embodiment: the honeycomb structure of the buffer layer 3 is filled with a phase change material, which is paraffin. By filling the buffer layer 3 with the phase change material, the composite foam is given temperature regulation capability, which can maintain the temperature stability of the home environment to a certain extent and improve the functionality and practicality of the product.

[0027] Working Principle: Through the layering of surface layer 1, first functional layer 2, buffer layer 3, second functional layer 4, and bottom layer 5, users can integrate antibacterial, anti-mildew, heat insulation, sound insulation, cushioning, waterproofing, moisture-proofing, and anti-slip functions into one unit. This meets the multi-dimensional needs of comfort, safety, and hygiene in the home environment, comprehensively enhancing the user experience of home products. Simultaneously, the layers are laminated together using hot-melt adhesive film, resulting in a tighter bond and effectively preventing delamination, thus improving product quality and reliability. The antibacterial and anti-mildew layer, utilizing the antibacterial properties of nano-silver antibacterial fibers, effectively inhibits the growth of bacteria and mold, providing a healthy home environment and extending the lifespan of the composite foam. The heat insulation and sound insulation layer combines aerogel and polyurethane foam, integrating the low thermal conductivity of aerogel with the porous structure of polyurethane foam. The improved heat and sound insulation better meet the needs of homes for temperature regulation and a quiet environment. By designing the buffer layer 3 as a honeycomb structure, it can more effectively absorb energy when subjected to external impact, thus providing superior cushioning performance, protecting home furnishings and human safety, and enhancing practicality. The combination of polyvinyl alcohol acetal resin coating and XPE foam improves waterproof and moisture-proof performance, making it suitable for more humid home environments, such as kitchens and bathrooms. The design of the bottom layer 5 makes the composite foam less prone to slipping during use, increasing stability, and making it suitable for home products that need to be placed on flat surfaces, such as cushions and floor mats. The phase change material filled in the buffer layer 3 gives the composite foam temperature regulation capabilities, which can maintain a stable home environment temperature to a certain extent, improving the functionality and practicality of the product.
