Description

Technical Field

[0001] The utility model relates to the field of mattress products, in particular to a formaldehyde-removing hot-melt composite elastic material structure and a mattress using the same. Background Art

[0002] Most of the existing materials with formaldehyde removal function are formed by fixing granular formaldehyde removal materials between two layers of non-woven fabrics. When this kind of formaldehyde removal composite non-woven fabric is used in actual mattresses, the following problems mainly exist:

[0003] 1. The formaldehyde removal material is enclosed in the middle of the non-woven fabric, the non-woven fabric has large air resistance and poor air permeability, and the formaldehyde removal effect is not ideal;

[0004] 2. The composite non-woven fabric has poor comfort and is difficult to be used in the quilting layer on the surface of the mattress. Therefore, it is necessary to find another product that has both formaldehyde removal effect and comfort and can be used in mattress products. Currently, there is no corresponding product.

[0005] 3. In order to improve air permeability and comfort, if the non-woven fabric on one side of the granular formaldehyde-removing material is replaced with sponge or latex, the granular formaldehyde-removing material is fixed to the non-woven fabric by glue, and the fixation reliability is poor. During the reciprocating compression and rebound process of the sponge or latex, the granular formaldehyde-removing material is prone to loosening and detachment. Since the sponge or latex has a porous and breathable structure, and accelerates the air flow during its compression and rebound process, the accelerated flow of air can easily carry the detached granular formaldehyde-removing material through the pores and cause it to fall into the surrounding environment, which is not only not conducive to the cleanliness and hygiene of the surrounding environment, but also affects the long-term formaldehyde removal effect. Summary of the invention

[0006] The purpose of the utility model is to solve the above-mentioned problems existing in the prior art and to provide a formaldehyde-removing hot-melt composite elastic material structure and a mattress using the same. The formaldehyde-removing material, the elastic layer and the cushion layer are bonded by a hot-melt layer. The formaldehyde-removing material can be stably adhered to the hot-melt layer and clamped between the elastic layer and the cushion layer. Even during use, the formaldehyde-removing material is not easy to fall off due to the external force of the reciprocating compression and rebound of the elastic layer and the airflow, and can always be stably fixed on the hot-melt layer, and it is also beneficial to improve the formaldehyde removal efficiency. The formaldehyde-removing hot-melt composite elastic material structure meets the requirements of air permeability and comfort when in use, and can also prevent the formaldehyde-removing material from falling off. It can effectively ensure the formaldehyde removal effect for a long time and avoid affecting the cleanliness and hygiene of the surrounding environment.

[0007] The above technical purpose of the utility model is mainly solved by the following technical solutions: a formaldehyde-removing hot-melt composite elastic material structure, characterized in that it includes a formaldehyde-removing hot-melt layer, an elastic layer composited on at least one side of the formaldehyde-removing hot-melt layer, and a composite cushion layer on the other side of the formaldehyde-removing hot-melt layer, the formaldehyde-removing hot-melt layer includes a formaldehyde-removing material layer and a hot-melt layer, the hot-melt layer is hot-melt-bonded to the formaldehyde-removing material layer, and the hot-melt layer is hot-melt-bonded to the elastic layer. The formaldehyde-removing material is bonded by the hot-melt layer, and the formaldehyde-removing material can be stably adhered to the hot-melt layer. Even if it is subjected to the external force of the reciprocating compression and rebound of the elastic layer and the airflow during use, it is not easy for the formaldehyde-removing material to fall off, and it can always be stably fixed on the hot-melt layer, and it is also beneficial to improve the formaldehyde-removing efficiency, which not only meets the requirements of the formaldehyde-removing hot-melt composite elastic material structure having air permeability and comfort when in use, but also can prevent the formaldehyde-removing material from falling off, can effectively preserve the formaldehyde-removing effect for a long time, and avoid affecting the cleanliness and hygiene of the surrounding environment.

[0008] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: the hot melt layer is a hot melt film or a hot melt net, and the thickness of the hot melt layer is 0.08-0.5 mm. The hot melt film or the hot melt net is used to fix the granular formaldehyde removal material, which can completely fix the formaldehyde removal material on the hot melt film or the hot melt net, and the fixing effect is stable and reliable. The thickness of the hot melt layer is relatively thin, which can not only fix the formaldehyde removal material, but also fix the elastic layer and the cushion layer, and the hot melt layer consumes less hot melt material, which is also conducive to cost saving.

[0009] The material of the elastic layer is mainly polyurethane foam material, thermoplastic elastomer foam material, rubber foam material and silicone foam material. Preferably, the elastic layer is a sponge layer or a latex layer.

[0010] Preferably, the cushion layer is a cloth layer, a sponge layer or a latex layer. The material of the cushion layer can be the same as or different from that of the elastic layer. The material of the cushion layer can be an elastic breathable material, a natural fiber cloth, a man-made fiber cloth, or artificial leather.

[0011] Preferably, the hot melt layer is at least two layers, which is beneficial to increase the overall thickness, elasticity and content of the formaldehyde-removing hot melt composite elastic material structure, thereby improving the overall performance of the formaldehyde-removing hot melt composite elastic material structure, further improving the applicability and adaptability.

[0012] Preferably, when the cushion layer is a sponge layer or a latex layer, the cushion layer and the elastic layer have different support hardnesses, which is beneficial to forming appropriate and layered elasticity, thereby providing a cushioning effect and good elastic support.

[0013] In order to facilitate the subsequent application of the formaldehyde-removing hot-melt composite elastic material structure, the thickness of the elastic layer is 0.5 to 2 cm.

[0014] In order to increase the composite stability and reliability of the formaldehyde-removing material layer and the hot melt layer and prevent the formaldehyde-removing material particles in the formaldehyde-removing material layer from falling off, the mesh size of the hot melt mesh is 20 to 40 meshes, and the formaldehyde-removing material in the formaldehyde-removing material layer is 20 to 40 meshes. The formaldehyde-removing hot melt layer is a composite layer in which the formaldehyde-removing material in the formaldehyde-removing material layer is embedded in the mesh holes of the hot melt mesh and hot-pressed with the hot melt layer, so as to save the consumption of hot melt material by the hot melt mesh.

[0015] The mattress using the formaldehyde-removing hot-melt composite elastic material structure comprises at least one of the layered structures of a quilting layer, a buffer layer, a support layer, and an edge layer, and is characterized in that the layered structure is the above-mentioned hot-melt composite sponge material. The mattress in this technical solution has all the beneficial effects of the formaldehyde-removing hot-melt composite elastic material structure, making the mattress not only comfortable and breathable, but also having a good formaldehyde-removing effect, which can effectively improve human sleep and is also beneficial to physical health.

[0016] The utility model has the beneficial effects:

[0017] 1. The formaldehyde-removing material layer, elastic layer and cushion layer are fixed simultaneously through the hot-melt layer to form an integrated structure. The formaldehyde-removing material can be stably and reliably fixed on the hot-melt layer, effectively solving the problem of formaldehyde-removing material falling off and ensuring the adhesion stability of the formaldehyde-removing material.

[0018] 2. For the formaldehyde-removing hot-melt composite elastic material structure, the porous structure of the elastic layer has good air permeability, which promotes air circulation during the compression and rebound process, so that the formaldehyde-removing material can efficiently contact the air and efficiently decompose the formaldehyde substances in the air, which is beneficial to improve the formaldehyde removal efficiency.

[0019] 3. The mating surface of the elastic layer and the cushion layer is a spatial interlocking mating surface. The yin-yang interlocking of the mating surface on the elastic layer and the cushion layer is a spatial interlocking mating surface, which is beneficial to increase the area of ​​the mating surface, thereby increasing the area of ​​the hot melt layer, and then increasing the area of ​​the formaldehyde removal material layer, thereby achieving the purpose of increasing the amount of formaldehyde removal material, and realizing the purpose of further improving the formaldehyde removal efficiency and increasing the effectiveness.

[0020] 4. When the formaldehyde-free hot-melt composite elastic material structure is applied to a mattress, an elastic layer is set as the filling material for the comfort layer. Compared with composite materials such as non-woven fabrics, it has better comfort and breathability, and has certain cushioning and massage effects. By combining elastic layers of different types and specifications, it can meet the comfort requirements of different groups of people and effectively improve the user's rest and sleep quality.

[0021] 5. When the formaldehyde-free hot-melt composite elastic material structure is applied to a mattress, and the cushion layer is a sponge layer or a latex layer, the supporting hardness of the cushion layer and the elastic layer are inconsistent, which is conducive to forming a suitable and layered elasticity, thereby facilitating the provision of a cushioning effect and good elastic support.

[0029] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0030] Example 1: Figure 1 As shown, the formaldehyde-removing hot-melt composite elastic material structure includes a formaldehyde-removing hot-melt layer 2, an elastic layer 1 composited on at least one side, a cushion layer 5 composited on the other side of the formaldehyde-removing hot-melt layer 2, the formaldehyde-removing hot-melt layer 2 includes a formaldehyde-removing material layer 3 and a hot-melt layer 4, the hot-melt layer 4 hot-melt-bonded the formaldehyde-removing material layer 3, and the hot-melt layer 4 hot-melt-bonded the elastic layer 1.

[0031] For the elastic layer 1, the cushion layer 5 and the hot melt layer 4:

[0032] The material of the elastic layer 1 is mainly polyurethane foam material, thermoplastic elastomer foam material, rubber foam material and silicone foam material. Preferably, the elastic layer 1 is a sponge layer or a latex layer.

[0033] The cushion layer 5 is a cloth layer, a sponge layer or a latex layer. In practical applications, the material of the cushion layer 5 can be the same as or different from the material of the elastic layer 1. The material of the cushion layer 5 can be an elastic breathable material, a natural fiber cloth, an artificial fiber cloth, or an artificial leather.

[0034] The material of the hot melt layer 4 is one of TPU, PES, EVA, EAA and PA, and TPU is a preferred material.

[0035] The formaldehyde-removing material in the formaldehyde-removing material layer 3 is granular, and a layered structure is formed by evenly spreading the formaldehyde-removing material. The formaldehyde-removing material is a formaldehyde-removing catalyst or activated carbon. The present embodiment adopts a formaldehyde-removing catalyst, which is a formaldehyde-removing granule and a supported formaldehyde-removing catalyst, which has a carrier and an active component, and the active component is supported on the carrier, wherein the carrier is activated carbon or titanium dioxide, preferably activated carbon. The active component is platinum or palladium, preferably platinum.

[0036] In the present technical solution, the formaldehyde-removing material is bonded by the hot-melt layer 4, and the formaldehyde-removing material can be stably adhered to the hot-melt layer 4. Even if it is subjected to the external force of the reciprocating compression and rebound of the elastic layer 1 and the airflow during use, the formaldehyde-removing material is not easy to fall off and can always be stably fixed on the hot-melt layer 4. The formaldehyde-removing hot-melt composite elastic material structure meets the requirements of breathability and comfort during use, and can prevent the formaldehyde-removing material from falling off. The formaldehyde-removing effect can be effectively preserved for a long time and the cleanliness and hygiene of the surrounding environment can be avoided.

[0037] That is, the formaldehyde-removing material is evenly spread on the hot melt layer 4 to form a layered distribution, and then the formaldehyde-removing material and the hot melt layer 4 are hot-pressed to make the formaldehyde-removing material layer 3 and the hot melt layer 4 composite to form the formaldehyde-removing hot melt layer 2, and then the elastic layer 1 and the cushion layer 5 are hot-pressed and composited on both sides of the formaldehyde-removing hot melt layer 2 to form a formaldehyde-removing hot melt composite elastic material structure. Alternatively, the cushion layer 5, the hot melt layer 4, the formaldehyde-removing material evenly spread on the hot melt layer 4, and then the elastic layer 1 are laid in sequence, and finally the stacked layers of materials are composited into an integrated structure.

[0038] Among them, the most basic technical solution is a four-layer structure, including a cushion layer 5, a hot melt layer 4, a formaldehyde removal material layer 3 and an elastic layer 1. Figure 2 As shown, the elastic layer 1 is a sponge layer or a latex layer, and the cushion layer 5 is a cloth layer (the cloth can be made of natural materials or artificial materials). Figure 3 As shown, the elastic layer 1 is a sponge layer or a latex layer, and the cushion layer 5 is a sponge layer or a latex layer.

[0039] For the formaldehyde-removing hot-melt composite elastic material structure, the formaldehyde-removing material can be fixed on the hot-melt layer 4 before fixing the elastic layer 1 and the cushion layer 5, which effectively solves the possibility of the formaldehyde-removing material falling off and ensures the adhesion stability of the formaldehyde-removing material. That is, in the present technical solution, hot-melt film, hot-melt mesh or hot-melt particles are used, and the hot pressing technology is used to realize the integrated composite of granular formaldehyde-removing material with the hot-melt layer 4, the elastic layer 1 and the cushion layer 5 to prevent the formaldehyde-removing material particles from falling off.

[0040] In the actual processing and production process: the arranged elastic layer 1, formaldehyde-removing material layer 3, hot melt layer 4 and cushion layer 5 are hot pressed and composited, the composite temperature is 80-180°C, the hot pressing and composite time is 2-10 minutes, the compression amount of the composite hot pressing roller is 20%-70% of the total thickness of each layer of material, and the hot pressing and composite is depressurized after cooling to ensure the stability of the formaldehyde-removing hot melt composite elastic material structure composited into an integrated molding.

[0041] In further optimizing the above scheme, the hot melt layer 4 is a hot melt film or a hot melt net, and the thickness of the hot melt layer 4 is 0.08-0.5 mm. The hot melt film or the hot melt net is used to fix the granular formaldehyde-removing material, and the formaldehyde-removing material can be completely fixed on the hot melt film or the hot melt net, and the fixing effect is stable and reliable. The thickness of the hot melt layer 4 is relatively thin, which can not only fix the formaldehyde-removing material, but also fix the elastic layer and the cushion layer, and the hot melt layer 4 consumes less hot melt material, which is also conducive to cost saving.

[0042] For this technical solution: using hot melt film or hot melt mesh to fix the granular formaldehyde-removing material, the formaldehyde-removing material can be completely fixed on the hot melt film or hot melt mesh. The hot melt film or hot melt mesh fixes the formaldehyde-removing material while fixing the elastic layer 1 and the cushion layer 5, which greatly improves the processing efficiency, and the fixing effect is stable and reliable.

[0043] In order to further meet the needs of mattresses, further improve elasticity or further increase the content of formaldehyde-removing materials to improve the formaldehyde-removing effect, and make the formaldehyde-removing materials fixed stably and reliably: the hot-melt layer 4 is at least two layers. It is beneficial to increase the overall thickness, elasticity and formaldehyde-removing hot-melt composite elastic material structure, thereby improving the overall performance of the formaldehyde-removing hot-melt composite elastic material structure, further improving applicability and adaptability.

[0044] In a further optimized solution, the adhesive surface of the elastic layer 1 located at the top layer is a spatially profiled surface (i.e., a surface with a regularly or irregularly distributed concave-convex structure, which is conceivable to those skilled in the art, and the corresponding drawings are omitted to avoid redundancy). The spatially profiled surface is conducive to increasing the air permeability during use and has a certain massage effect.

[0045] Further, taking the plane where the formaldehyde-removing hot-melt layer 2 is located as the reference plane, and the direction perpendicular to the reference plane as the height direction, the spatial profiled surface is a spatial profiled surface formed by superimposing transverse waves and longitudinal waves with a certain height corresponding to the transverse and longitudinal directions of the reference plane.

[0046] In practical applications, the thickness of the elastic layer 1 is 0.5-2 cm.

[0047] In order to save the consumption of hot-melt materials, the hot-melt layer 4 adopts the technical solution of hot-melt mesh. The mesh size of the hot-melt mesh is 20 to 40 meshes, the formaldehyde-removing material in the formaldehyde-removing material layer 3 is 20 to 40 meshes, and the formaldehyde-removing hot-melt layer 2 is a composite layer in which the formaldehyde-removing material in the formaldehyde-removing material layer 3 is embedded in the mesh of the hot-melt mesh and is hot-pressed with the hot-melt layer 4.

[0048] Embodiment 2: The difference between this technical solution and embodiment 1 is that the hot-melt layer 4 has two layers. In practical applications, it is feasible to have more than two layers of the hot-melt layer 4.

[0049] When the hot melt layer 4 is two layers or more, it is beneficial to increase the overall thickness, elasticity and formaldehyde-removing material content of the formaldehyde-removing hot melt composite elastic material structure, thereby improving the overall performance of the formaldehyde-removing hot melt composite elastic material structure, further improving the applicability and adaptability, and is also beneficial to increasing the service life of the formaldehyde-removing hot melt composite elastic material structure.

[0050] When the hot-melt layer 4 is two layers, there are at least four solutions:

[0051] Option 1: If Figure 4 As shown, the interlayer between the two hot-melt layers 4 is the elastic layer 1, the top layer and the bottom layer are cushion layers 5, and both cushion layers 5 are fabric layers.

[0052] Option 2: If Figure 5 As shown, the cushion layer 5 and the elastic layer 1 are both made of sponge or latex, and the materials of the cushion layer 5 and the elastic layer 1 can be the same or different.

[0053] Option 3: If Figure 6 As shown, in this scheme, the interlayer between the two hot-melt layers 4 is an elastic layer 1, the top layer and the bottom layer are cushion layers 5, one cushion layer 5 is a cloth layer, and the other cushion layer 5 is a sponge layer or a latex layer.

[0054] Option 4: If Figure 7 As shown, in this solution, the interlayer between the two hot-melt layers 4 is a cushion layer 5 , and the cushion layer 5 is a cloth layer, and the top layer and the bottom layer are elastic layers 1 .

[0055] Example 3: Figure 8 and Fig. 9As shown, the difference between the present technical solution and the embodiment 1 or the embodiment 2 is that the mating surface of the elastic layer 1 and the cushion layer 5 is a spatial interlocking mating surface. The yin-yang interlocking of the mating surface on the elastic layer and the cushion layer is a spatial interlocking mating surface, which is beneficial to increase the area of ​​the mating surface, thereby increasing the area of ​​the hot melt layer, and then increasing the area of ​​the formaldehyde removal material layer, so as to achieve the purpose of increasing the amount of formaldehyde removal material, and further improve the formaldehyde removal efficiency and increase the actual effect.

[0056] Example 4: Fig.10 As shown, the technical solution relates to a mattress using a formaldehyde-free hot-melt composite elastic material structure:

[0057] The mattress using the formaldehyde-removing hot-melt composite elastic material structure includes at least one layered structure selected from the group consisting of a quilting layer 8, a buffer layer 9, a support layer 10, and a surrounding edge layer 11, and is characterized in that the layered structure is the hot-melt composite sponge material described in Example 1.

[0058] The mattress in this technical solution has all the beneficial effects of the formaldehyde-removing hot-melt composite elastic material structure, making the mattress not only comfortable and breathable to use, but also having a good formaldehyde-removing effect, which can effectively improve human sleep and is also beneficial to physical health.

[0059] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. In the above embodiments, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
