Description

Technical Field

[0001] This utility model relates to the field of sponge pads, and in particular to a long-lasting antibacterial and anti-corrosion sponge pad. Background Technology

[0002] Traditional sponge materials, due to their porous structure and excellent elasticity, are widely used in home furnishings, medical applications, and sports. However, their inherent characteristics also bring significant technical bottlenecks: First, the porous surface easily absorbs moisture and organic matter, providing a breeding ground for bacteria and mold, which can easily lead to hygiene and safety hazards with long-term use. Second, traditional antibacterial treatments mostly adopt surface coating or single-functional layer designs, which have problems such as short antibacterial effect, uneven penetration, and weak bonding with the matrix. In addition, sponge products are prone to absorbing and retaining moisture in humid environments, leading to odor accumulation and internal structural deterioration. Therefore, there is an urgent need to develop a long-lasting antibacterial and anti-corrosion sponge pad that can inhibit the growth of microorganisms in the long term, while being breathable, deodorizing, and maintaining user comfort. Utility Model Content

[0003] In order to overcome the shortcomings of traditional sponge pads, which mostly adopt surface coating or single functional layer design for antibacterial treatment, such as short antibacterial effect, uneven penetration and weak bonding with the substrate, this utility model aims to provide a long-lasting antibacterial and anti-corrosion sponge pad that can inhibit the growth of microorganisms for a long time, while being breathable, deodorizing and maintaining the comfort of use.

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

[0005] A long-lasting antibacterial and anti-corrosion sponge pad includes a sponge base layer and an antibacterial and anti-corrosion outer layer covering the entire outer surface of the sponge base layer.

[0006] The sponge matrix layer includes a first sponge layer and a second sponge layer stacked together. The first sponge layer and the second sponge layer are made of porous polyurethane sponge, polyvinyl alcohol sponge, or natural latex sponge. An antibacterial and anti-corrosion inner layer is disposed between the first sponge layer and the second sponge layer. The two sides of the antibacterial and anti-corrosion inner layer are fixedly bonded to the first sponge layer and the second sponge layer by adhesive. The two sides of the antibacterial and anti-corrosion inner layer are also provided with a number of protrusions that are evenly spaced and extend into the first sponge layer and the second sponge layer, respectively. The height of the protrusions is two-thirds of the thickness of the antibacterial and anti-corrosion inner layer.

[0007] The antibacterial and anti-corrosion outer layer includes an innermost antibacterial layer; a breathable and deodorizing layer is fixedly bonded to the outside of the antibacterial layer; and a waterproof and breathable surface layer is fixedly bonded to the outside of the breathable and deodorizing layer.

[0008] Furthermore, the antibacterial layer is a polyurethane fiber layer containing nano-silver ions; the highly efficient antibacterial properties of nano-silver ions inhibit the growth of bacteria and mold, while polyurethane fibers have excellent elasticity and breathability.

[0009] Furthermore, the breathable and deodorizing layer is a non-woven fabric layer loaded with activated carbon particles, achieving the effect of efficiently adsorbing odors and facilitating moisture and air circulation.

[0010] Furthermore, the waterproof and breathable surface layer is a polytetrafluoroethylene microporous membrane; it has excellent waterproof and breathable properties, achieving a synergistic effect of liquid water barrier and gaseous water vapor permeability.

[0011] Furthermore, the antibacterial and antiseptic inner layer is a polymer layer containing quaternary ammonium salt compounds; it achieves highly efficient and long-lasting broad-spectrum antibacterial properties through chemical bonding and sustained release.

[0012] Furthermore, the protrusion has a conical or cylindrical geometric structure, which can enhance the mechanical anchoring effect between the antibacterial and antiseptic inner layer and the sponge layer, improve the interfacial bonding strength, and optimize the slow-release penetration effect of the antibacterial agent.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves the effect of long-term inhibition of microbial growth, while being breathable, deodorizing, and maintaining user comfort. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: Example

[0019] A long-lasting antibacterial and antiseptic sponge pad, such as Figure 1-2 As shown, it includes a sponge matrix layer 1 and an antibacterial and antiseptic outer layer 2 covering the entire outer surface of the sponge matrix layer 1.

[0020] The sponge matrix layer 1 includes a first sponge layer 11 and a second sponge layer 12 stacked together. The first sponge layer 11 and the second sponge layer 12 are made of porous polyurethane sponge, polyvinyl alcohol sponge, or natural latex sponge. An antibacterial and anti-corrosion inner layer 13 is disposed between the first sponge layer 11 and the second sponge layer 12. The two sides of the antibacterial and anti-corrosion inner layer 13 are fixedly bonded to the first sponge layer 11 and the second sponge layer 12 by adhesive. On the two sides of the antibacterial and anti-corrosion inner layer 13, a plurality of protrusions 14 are evenly spaced and protruded, extending into the first sponge layer 11 and the second sponge layer 12 respectively. The height of the protrusions 14 is two-thirds of the thickness of the antibacterial and anti-corrosion inner layer 13.

[0021] The antibacterial and anti-corrosion outer layer 2 includes an innermost antibacterial layer 21; a breathable and deodorizing layer 22 is fixedly bonded to the outside of the antibacterial layer 21; and a waterproof and breathable surface layer 23 is fixedly bonded to the outside of the breathable and deodorizing layer 22.

[0022] Working principle:

[0023] This utility model of a sponge pad includes a sponge matrix layer 1 and an antibacterial and anti-corrosion outer layer 2 covering the entire outer surface of the sponge matrix layer 1. The sponge matrix layer 1 includes a first sponge layer 11 and a second sponge layer 12 stacked together. The first sponge layer 11 and the second sponge layer 12 are made of porous polyurethane sponge, polyvinyl alcohol sponge or natural latex sponge, providing elastic support for the sponge pad. An antibacterial and anti-corrosion inner layer 13 is disposed between the first sponge layer 11 and the second sponge layer 12. The antibacterial and anti-corrosion inner layer 13 is a polymer layer containing quaternary ammonium salt compounds, which achieves efficient and long-lasting broad-spectrum antibacterial properties through chemical bonding and slow release. At the same time, a number of protrusions 14 are evenly and uniformly protruding on both sides of the antibacterial and anti-corrosion inner layer 13, which respectively extend into the first sponge layer 11 and the second sponge layer 12, thereby enhancing the mechanical interlocking with the sponge layer and expanding the contact surface for slow release of antibacterial agents, achieving bidirectional penetration and antibacterial action.

[0024] The antibacterial and anti-corrosion outer layer 2 includes an innermost antibacterial layer 21, which is a polyurethane fiber layer containing nano-silver ions. The highly efficient antibacterial properties of nano-silver ions inhibit the growth of bacteria and mold, while the polyurethane fiber has excellent elasticity and breathability. A breathable and deodorizing layer 22 is fixedly bonded to the outside of the antibacterial layer 21. The breathable and deodorizing layer 22 is a non-woven fabric layer loaded with activated carbon particles, which achieves efficient adsorption of odors and moisture permeability. A waterproof and breathable surface layer 23 is fixedly bonded to the outside of the breathable and deodorizing layer 22. The waterproof and breathable surface layer 23 is a polytetrafluoroethylene microporous membrane with excellent waterproof and breathable properties, achieving a synergistic effect of liquid water barrier and gaseous water vapor permeability.
