Description

Technical Field

[0001] The utility model relates to the technical field of sponges, in particular to a thermoplastic composite sponge. Background Art

[0002] Sponge has good softness and is often used in production and processing. Sponge has buffering and shock resistance. It is soft, light, elastic, and can bend. It can absorb and disperse external impact force to achieve a buffering effect. It has a series of excellent usability such as heat preservation and moisture-proof, heat insulation, sound insulation, anti-friction, anti-aging, and corrosion resistance. In life and industrial production, due to its various superior effects, sponge has become the preferred protective material;

[0003] The composite sponge used in the prior art is flammable. When the sponge is ignited by a fire source, the internal combustion speed is fast, which can easily cause a larger fire and threaten people's property and lives. At the same time, the burning sponge will be burned out and cannot be reused, which increases the waste of materials. When the composite sponge is used for floor protection in children's playgrounds and some training halls, it is stepped on barefoot or in socks during use, but the composite sponge has limited air permeability, resulting in odor after a period of use, affecting the user experience and the user's health. Therefore, a thermoplastic composite sponge is designed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a thermoplastic composite sponge.

[0005] The technical problem to be solved by the utility model is to provide a thermoplastic composite sponge which not only has a flame retardant effect but also has a deodorizing effect and is highly practical.

[0006] The utility model provides a thermoplastic composite sponge, comprising: a lower sponge layer, a heat insulation layer and an upper sponge layer, wherein a heat insulation layer is fixedly arranged above the lower sponge layer, an upper sponge layer is fixedly arranged above the heat insulation layer, the upper sponge layer is square, there are multiple upper sponge layers, and the multiple upper sponge layers are all in a linear array, a first flame retardant layer is fixedly arranged on the side and bottom of the lower sponge layer, and a second flame retardant layer is fixedly arranged on the side of the upper sponge layer.

[0007] Preferably, the first flame retardant layer and the second flame retardant layer are both made of chlorinated paraffin material.

[0008] Preferably, the heat insulation layer is made of asbestos material.

[0009] Preferably, an activated carbon layer is arranged in the center of the heat insulation layer, and a plurality of deodorizing holes are opened on the upper surface of the activated carbon layer.

[0010] Preferably, the bottom of the deodorizing hole is penetrated through the activated carbon layer, and the deodorizing hole is located at the bottom of the upper sponge layer.

[0011] Preferably, the number of the deodorizing holes is the same as that of the upper sponge layer, and the deodorizing holes are located at the bottom center of the upper sponge layer.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] 1. The utility model provides a heat-insulating layer, which is located between the upper sponge layers. While ensuring the elasticity of the thermoplastic composite sponge, when the lower sponge layer or the upper sponge layer is burned by a fire source, the heat-insulating layer separates the lower sponge layer or the upper sponge layer from each other to prevent the fire from continuing. In addition, by respectively providing a flame-retardant layer on the lower sponge layer and the upper sponge layer, the lower sponge layer or the upper sponge layer can be prevented from burning. The upper sponge layer is square, and there are multiple upper sponge layers, which are all in a linear array, so that after a single upper sponge layer is burned, the second flame-retardant layer on the upper sponge layer can separate the multiple upper sponge layers to prevent the fire source from burning the upper sponge layer completely.

[0014] 2. The utility model is provided with an activated carbon layer and deodorizing holes. When the upper sponge layer on the thermoplastic composite sponge is stepped on barefoot or with socks, the odor can enter the activated carbon layer through the deodorizing holes. The activated carbon layer absorbs the odor to prevent the odor from being emitted, thereby ensuring the user experience and the health of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] During actual use, by setting the heat insulation layer 2, the heat insulation layer 2 is located between the upper sponge layers to ensure the elasticity of the thermoplastic composite sponge. When the lower sponge layer 1 or the upper sponge layer 3 is burned by a fire source, the heat insulation layer 2 separates the lower sponge layer 1 or the upper sponge layer 3 from each other to prevent the fire from continuing, and by respectively providing a flame retardant layer on the lower sponge layer 1 and the upper sponge layer 3, the lower sponge layer 1 or the upper sponge layer 3 can be prevented from burning, and the upper sponge layer 3 is square, and there are multiple upper sponge layers 3, and the multiple upper sponge layers 3 are all in a linear array, so that after a single upper sponge layer 3 is burned, the second flame retardant layer 301 on the upper sponge layer 3 can separate the multiple upper sponge layers 3 to prevent the fire source from burning the upper sponge layer out.

[0026] In this embodiment, the first flame retardant layer 101 and the second flame retardant layer 301 are both made of chlorinated paraffin material. Chlorinated paraffin is a white to light yellow solid powder, odorless, non-toxic, flame resistant, and elastic.

[0027] In this embodiment, the heat insulation layer 2 is made of asbestos material, which is fire-resistant and has a heat insulation effect against external fire sources.

[0028] In this embodiment, an activated carbon layer 201 is disposed in the center of the heat insulation layer 2 , and a plurality of deodorizing holes 202 are formed on the upper surface of the activated carbon layer 201 .

[0029] In this embodiment, the bottom of the deodorizing hole 202 is penetrated in the activated carbon layer 201 , and the deodorizing hole 202 is located at the bottom of the upper sponge layer 3 .

[0030] In this embodiment, the number of deodorizing holes 202 is the same as the number of the upper sponge layer 3, and the deodorizing holes 202 are located at the bottom center of the upper sponge layer 3, so that the odor on the upper sponge layer 3 can enter the activated carbon layer 201 through the deodorizing holes 202 to achieve the deodorizing effect.
