Description

Technical Field

[0001] This utility model relates to the field of composite sponge pads, and more particularly to a moisture-proof composite sponge pad. Background Technology

[0002] As people's demands for quality of life increase, the demand for functional home and outdoor products is growing. Among these, moisture-proof, antibacterial, and comfort have become key indicators. Although traditional sponge mats have good cushioning and softness, they generally have problems such as easy moisture absorption, mold growth, and poor anti-slip properties. After long-term use, they are prone to internal dampness, structural deformation, odor, and even health problems. The defects of ordinary sponge mats are more prominent, especially in humid environments (such as bathrooms, kitchens, and outdoor camping). Therefore, there is an urgent need to develop a moisture-proof composite sponge mat that can solve the performance defects in humid environments and has the functions of high-efficiency moisture-proof, breathable antibacterial, long-lasting anti-slip, and comfortable durability. Utility Model Content

[0003] In order to overcome the common problems of traditional sponge pads, such as easy moisture absorption, mold growth, and poor anti-slip properties, which can lead to internal dampness, structural deformation, odor, and even health problems after long-term use, this utility model aims to provide a moisture-proof composite sponge pad that can solve the performance defects in humid environments and has the advantages of high-efficiency moisture-proof, breathable antibacterial, long-lasting anti-slip, and comfortable durability.

[0004] This utility model is achieved by the following specific technical means:

[0005] A moisture-proof composite sponge pad includes a sponge base layer 1, on both sides of which a moisture-proof bottom layer 2 and a moisture-proof top layer 3 are fixedly and adhered.

[0006] The moisture-proof bottom layer 2 includes a lower moisture-proof layer 21 that is fixedly bonded to the sponge substrate layer 1; and an anti-slip layer 22 that is fixedly bonded to the lower moisture-proof layer 21 on the side away from the sponge substrate layer 1.

[0007] The moisture-proof surface layer 3 includes an upper moisture-proof layer 31 that is fixedly bonded to the sponge substrate layer 1; an antibacterial and mildew-proof layer 32 is provided on the side of the upper moisture-proof layer 31 away from the sponge substrate layer 1; and a surface layer 33 is fixedly bonded to the side of the antibacterial and mildew-proof layer 32 away from the upper moisture-proof layer 31.

[0008] The sponge matrix layer 1 includes a sponge layer 11 made of polyurethane sponge or memory foam, and the outer surface of the sponge layer 11 is entirely covered with a waterproof and breathable layer 12.

[0009] Furthermore, the waterproof and breathable layer 12 is a polytetrafluoroethylene microporous membrane or a polyurethane waterproof and breathable membrane; it has excellent waterproof and breathable properties, achieving a synergistic effect of liquid water barrier and gaseous water vapor permeability.

[0010] Furthermore, both the lower moisture-proof layer 21 and the upper moisture-proof layer 31 are non-woven fabric layers impregnated with a hydrophobic agent; the hydrophobic agent forms a nanoscale hydrophobic film on the surface of the non-woven fabric fibers, blocking the penetration of liquid water, preserving the porous structure of the non-woven fabric to allow moisture to escape, and avoiding internal condensation.

[0011] Furthermore, the anti-slip layer 22 is a silicone layer or rubber layer with raised anti-slip textures on the surface; which significantly improves the anti-slip properties, durability and safety of the product.

[0012] Furthermore, the antibacterial and antifungal layer 32 is a coating layer containing nano-silver ions or quaternary ammonium salt compounds, thus imparting microbial inhibition capabilities.

[0013] Furthermore, the surface layer 33 is a waterproof fabric layer or a microfiber leather layer with breathable micropores on its surface; this improves waterproofness, prevents liquid water from seeping into the sponge pad, and ensures breathability.

[0014] Furthermore, the sponge layer 11 and the waterproof and breathable layer 12 are bonded and fixed together by a hot melt adhesive layer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention solves the performance defects in humid environments and has the effects of high-efficiency moisture-proof, breathable antibacterial, long-lasting anti-slip, and comfortable and durable. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings: Example

[0021] A moisture-proof composite sponge pad, such as Figs. 1-2 As shown, it includes a sponge base layer 1, with a moisture-proof bottom layer 2 and a moisture-proof top layer 3 fixedly bonded to both sides of the sponge base layer 1.

[0022] The moisture-proof bottom layer 2 includes a lower moisture-proof layer 21 that is fixedly bonded to the sponge substrate layer 1; and an anti-slip layer 22 that is fixedly bonded to the lower moisture-proof layer 21 on the side away from the sponge substrate layer 1.

[0024] The sponge matrix layer 1 includes a sponge layer 11 made of polyurethane sponge or memory foam, and the outer surface of the sponge layer 11 is entirely covered with a waterproof and breathable layer 12.

[0025] Working principle:

[0026] This utility model of a sponge pad includes a sponge base layer 1, with a moisture-proof bottom layer 2 and a moisture-proof top layer 3 fixedly bonded to both sides of the sponge base layer 1. The sponge base layer 1 includes a sponge layer 11 made of polyurethane sponge or memory foam, providing elastic support. The outer surface of the sponge layer 11 is entirely covered with a waterproof and breathable layer 12, which is a polytetrafluoroethylene microporous membrane or a polyurethane waterproof and breathable membrane. It has excellent waterproof and breathable properties, achieving a synergistic effect of liquid water barrier and gaseous water vapor permeability. The moisture-proof bottom layer 2 includes a lower moisture-proof layer 21 and an anti-slip layer 22, and the moisture-proof top layer 3 includes an upper moisture-proof layer 31, an antibacterial and anti-mildew layer 32, and a surface layer 33. The lower moisture-proof layer 21 and the upper moisture-proof layer 31 are both non-woven fabric layers impregnated with a hydrophobic agent, which makes the non-woven fabric fibers... A nano-scale hydrophobic film forms on the surface, blocking liquid water penetration while retaining the porous structure of the non-woven fabric to allow moisture to escape, preventing internal condensation and preventing the sponge from becoming damp and deformed. The anti-slip layer 22 is a silicone or rubber layer with raised anti-slip textures on the surface. The bottom anti-slip layer 22 uses surface textures to increase friction and prevent slippage during use, significantly improving the product's anti-slip properties, durability, and safety. The antibacterial and anti-mildew layer 32 is a coating layer containing nano-silver ions or quaternary ammonium salt compounds, giving it the ability to inhibit microorganisms, directly killing bacteria and molds that come into contact with it, and preventing the growth of odors. The surface layer 33 is a waterproof fabric layer or microfiber leather layer with breathable micropores on the surface to prevent liquid water from penetrating the sponge pad, ensuring breathability, maintaining a comfortable feel, and quickly wicking away sweat to keep it dry.
