Detailed Description
In order to make the purpose, technical solution and effect of the present application clearer and clearer, the present application is further described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1, fig. 1 is a schematic cross-sectional view of an antibacterial composite material according to an embodiment of the present disclosure. In this embodiment, the antibacterial composite material includes an antibacterial layer 10 and a bactericidal layer 20.
The antibacterial layer 10 is a porous material layer, and the nano silver antibacterial agent is uniformly dispersed in the porous material layer, so the antibacterial layer 10 is also called a nano silver antibacterial layer. The sterilization layer 20 is at least located on one side surface of the antibacterial layer 10, and the sterilization layer 20 includes a quaternary ammonium salt sterilization agent, so the sterilization layer 20 is also called a quaternary ammonium salt sterilization layer.
In the embodiment, the quaternary ammonium salt sterilization layer is compounded on the surface of the nano silver antibacterial layer, so that on one hand, the quaternary ammonium salt sterilization layer can be combined with the fibers of the porous material layer by utilizing the strong reactivity of positively charged nitrogen atoms in quaternary ammonium salt molecules to form a net-shaped structure layer to cover the surface of the porous material layer, so that the nano silver antibacterial agent is fixed, and the antibacterial performance is prevented from being weakened due to the fact that the nano silver antibacterial agent is separated from the porous material; on the other hand, a bactericide is added, and the combination of the two bactericides and the bactericide can increase the variety of bacteria inhibiting (killing) strains and effectively kill various bacteria.
In one embodiment, the nano-silver antimicrobial agent comprises at least one of a nano-silver ion antimicrobial agent and a nano-silver elemental antimicrobial agent. Specifically, the nano silver ion antibacterial agent is an antibacterial agent formed by attaching nano silver ions on a carrier, the carrier of the nano silver ion antibacterial agent can be mineral substances such as zirconium phosphate, apatite, zeolite and the like, and the nano silver ion antibacterial agent with a nano structure can be obtained by attaching the nano silver ions on the carrier. The obtained nano silver ion antibacterial agent has particle size of 20 nm-400 nm, such as 50nm, 100nm, 150nm, 200nm, 300nm, etc.; the concentration of the nano silver ion in the nano silver ion antibacterial agent is 50ppm to 5000ppm, such as 150ppm, 350ppm, 1000ppm, 2000ppm, 3000ppm, 4000ppm, etc.
The nano silver simple substance is nano silver powder obtained by physical or chemical means, and the single silver is prepared into nano micro powder, so that the unit surface area of silver can be increased, the release amount of silver ions can be increased, and the bactericidal power can be improved. The silver simple substance can be directly used or prepared into colloidal solution for use, and in the using process, the silver simple substance can be oxidized into silver ions by an oxidant in the air to play an antibacterial role. The particle size of the nano silver simple substance antibacterial agent can be 100 nm-10 μm, such as 50nm, 20nm, 1nm, 50 μm, 30 μm and the like.
The nano silver ion antibacterial agent adopted in the embodiment of the application is a very high-efficiency antibacterial agent, and can effectively sterilize at very low concentration (ppm level or even lower). The nano silver ions can strongly attract sulfhydryl (-SH) on the protease in the bacterial body, and can be rapidly combined with the sulfhydryl (-SH) to inactivate the protease, so that the bacteria can die. When the bacteria are killed by the nano silver ions, the nano silver ions are dissociated from the bacterial corpses and then contact with other bacterial colonies, and the process is repeatedly carried out, so that the nano silver ions have strong sterilization durability and are a permanent bactericide. And the nano silver ions do not cause resistant bacteria to appear in the bacteria and the viruses in the bacteria inhibiting (killing) mode of the bacteria and the viruses.
In one embodiment, the nano-silver antimicrobial agent may be uniformly dispersed in the porous material layer by spraying, dipping, or coating. The addition amount of the nano silver antibacterial agent in the porous material layer is 1-50%, such as 5%, 15%, 25%, 40% and the like. It can be understood that the addition amount of the nano silver antibacterial agent in the porous material layer can be adaptively adjusted according to the antibacterial grade of the product to be actually applied.
In one embodiment, the porous material layer may be a thin porous material layer, which may be one or more of a tissue paper layer, a nonwoven material layer, or a textile material layer. Wherein, the tissue paper layer is a sheet-shaped material which is prepared by dispersing plant fiber raw materials into single fiber and then interweaving and forming, such as toilet paper, facial tissue, wiping paper and the like. The basis weight of the thin apertured material layer may be 12g/m2～50g/m2E.g. 15g/m2、20g/m2、25g/m2、40g/m2Etc.; the thickness is 150 μm to 400 μm, such as 180 μm, 230 μm, 270 μm, 350 μm, etc.
In one embodiment, the quaternary ammonium salt sterilizing layer 20 is formed of a quaternary ammonium salt sterilizing agent coated on the surface of the antibacterial layer 10. The quaternary ammonium salt bactericide can be coated on one side surface of the thin porous material layer by spraying or roll coating, for example, to form the quaternary ammonium salt bactericide layer 20.
The quaternary ammonium salt bactericide can comprise at least one of dodecyl trimethyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, cyano quaternary ammonium salt, double-C alkyl quaternary ammonium bromide, polyazacyclo quaternary ammonium salt, polyquaternary ammonium salt, biquaternary ammonium salt and other quaternary ammonium salt bactericides.
