Description

Long-acting antibacterial and antiseptic sponge cushion Technical Field The utility model relates to the field of foam-rubber mats, in particular to a long-acting antibacterial and antiseptic foam-rubber mat. Background The traditional sponge material is widely applied to the fields of home, medical treatment, sports and the like due to the porous structure and excellent elasticity, however, the inherent characteristics of the sponge material also bring about obvious technical bottlenecks, namely firstly, the porous surface is easy to absorb water and organic matters, a temperature bed is provided for bacteria and mold breeding, health potential safety hazards are easily caused after long-term use, secondly, the traditional antibacterial treatment is mainly carried out by adopting surface coating or single functional layer design, the problems of short antibacterial time effect, uneven permeation, weak binding force with a matrix and the like exist, and in addition, the sponge product is easy to absorb moisture and store water in a humid environment, so that peculiar smell accumulation and internal structure degradation are caused, and therefore, the development of a long-acting antibacterial and anti-corrosion sponge cushion capable of inhibiting microorganism breeding for a long time, ventilating and deodorizing and keeping use comfort is needed. Disclosure of utility model The utility model aims to overcome the defects of short antibacterial time effect, uneven permeation and weak binding force with a matrix of the traditional sponge cushion, which are mostly designed by adopting surface coating or a single functional layer, and the technical problem to be solved by the utility model is to provide the long-acting antibacterial and antiseptic sponge cushion which can inhibit microorganism breeding for a long time, is breathable and deodorant and keeps use comfort. The utility model is achieved by the following specific technical means: A long-acting antibacterial and antiseptic sponge cushion comprises a sponge matrix layer and an antibacterial and antiseptic outer layer coated on the whole outer surface of the sponge matrix layer; The sponge matrix layer comprises a first sponge layer and a second sponge layer which are arranged in a stacked manner, wherein the first sponge layer and the second sponge layer are made of polyurethane sponge, polyvinyl alcohol sponge or natural latex sponge with porous structures, an antibacterial and anti-corrosion inner layer is arranged between the first sponge layer and the second sponge layer, the surfaces of the two sides of the antibacterial and anti-corrosion inner layer are fixedly bonded with the first sponge layer and the second sponge layer through bonding, a plurality of protrusions which extend into the first sponge layer and the second sponge layer respectively are uniformly and convexly arranged on the surfaces of the two sides of the antibacterial and anti-corrosion inner layer in an equidistant manner, and the heights of the protrusions are two thirds of the thickness of the antibacterial and anti-corrosion inner layer; The antibacterial and antiseptic outer layer comprises an antibacterial layer positioned at the innermost side, the outer side of the antibacterial layer is fixedly bonded with a breathable deodorizing layer, and the outer side of the breathable deodorizing layer is fixedly bonded with a waterproof breathable surface layer. The antibacterial layer is a polyurethane fiber layer containing nano silver ions, bacteria and mold breeding are inhibited through the efficient antibacterial property of the nano silver ions, and meanwhile, the polyurethane fiber has excellent elasticity and air permeability. Furthermore, the breathable deodorizing layer is a non-woven fabric layer loaded with active carbon particles, so that the effects of efficiently absorbing peculiar smell and permeable air are achieved. Furthermore, the waterproof breathable surface layer is a polytetrafluoroethylene microporous membrane, has excellent waterproof breathability, and realizes the synergistic effect of liquid water blocking and gaseous water vapor permeation. Furthermore, the antibacterial and antiseptic inner layer is a polymer layer containing quaternary ammonium salt compound, and the high-efficiency and durable broad-spectrum antibacterial property is realized through chemical bonding and slow release. Furthermore, the bulge is in a conical or cylindrical geometric structure, so that the mechanical anchoring effect of the antibacterial anti-corrosion inner layer and the sponge layer can be enhanced, the interface bonding strength is improved, and the slow release permeation effect of the antibacterial agent is optimized. Compared with the prior art, the utility model has the following beneficial effects: The utility model achieves the effects of inhibiting microorganism breeding for a long time, ventilating and deodorizing at the same time and keeping the use com
