Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities, in particular to a TPE composite memory pillow. Background Art
[0002] TPE soft glue is a thermoplastic elastomer. Due to its excellent elasticity, ultra-long extensibility, good safety and softness close to human skin, it has been used in the production of pillows, mattresses and other sleep products in recent years. The existing technology directly injects TPE into a hollow pillow shape, which has good support and breathability. However, since it is an unfoamed material, the product is heavy and the cost is high; at the same time, due to its good elasticity, it also leads to unstable support and shaking; the hollow design leads to unstable shape and size. Based on the above defects, some technicians have tried to compound TPE with memory foam to combine the advantages of both. However, TPE is a non-polar material and is difficult to compound with conventional adhesives.
[0003] In order to overcome the above defects, the prior art uses a TPE sheet containing a waterproof base fabric and places it in a foaming mold, and combines it with the memory foam through a foaming agent. The disadvantages of this process are that the fabric is too thin to form sufficient cross-linking and interpenetration with TPE, resulting in poor bonding strength. The use of a waterproof base fabric greatly reduces the air permeability of the product, and the waterproof base fabric affects the softness. The base fabric size is larger than TPE, which also causes the surface of the memory foam to be covered with the waterproof fabric, resulting in a decrease in comfort. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a TPE composite memory pillow to solve the technical problems in the prior art that a TPE sheet containing a waterproof base cloth is placed in a foaming mold and combined with the memory foam through a foaming agent. The use of the waterproof base cloth reduces the air permeability of the product, and the waterproof base cloth affects the softness. The base cloth size is larger than TPE, which also causes the surface of the memory foam to be covered with the waterproof cloth, resulting in a decrease in comfort.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a TPE composite memory pillow, including a pillow body, the pillow body including a sponge substrate, a grid-shaped TPE film is injection-molded on one side of the sponge substrate, and a memory foam is provided on the opposite side of the sponge substrate. The memory foam is foamed and wrapped around the exposed surface of the sponge substrate and the edges around it, and the edge of the memory foam is spliced with the edge of the grid-shaped TPE film.
[0006] According to an optional implementation, the grid-shaped TPE film is configured as a gradient structure.
[0007] According to an optional implementation, the edges of the grid-shaped TPE film are of a gradual structure.
[0008] According to an optional implementation, the thickness of the four edges of the grid-shaped TPE film ranges from 1 to 3 mm.
[0009] According to an optional implementation manner, the thickness of the grid-shaped TPE film ranges from 3 to 20 mm.
[0010] According to an optional embodiment, the size of the sponge substrate is consistent with the size of the grid-shaped TPE film.
[0011] According to an optional embodiment, the sponge substrate is an open-cell polyether or polyester type soft polyurethane foam.
[0012] According to an optional embodiment, the density of the sponge substrate is in the range of 20-100 kg / m 3 , thickness range is 2-7mm.
