Abstract

The invention relates to the field of nano materials and in particular relates to an anti-mould and antibacterial nano-silver floor. The nano-silver floor is characterized by sending a technical wood floor into a vacuum tank containing a nano-silver water solution; then carrying out microwave treatment, and then taking out the floor to undergo hot pressing, wherein the hot pressing pressure is 0.5-1.4MPa, and the hot pressing time is 1-5 minutes; the nano-silver water solution is formed by taking deionized water as a solvent and nano-silver as a solute, dissolving nano-silver into the deionized water, dissolving acrylic resin as a complexing agent and stabilizing agent into the deionized water, and then simultaneously adding a dispersing agent and a first reducing agent; the concentration of nano-silver is 50-150ppm, and the mass content of the acrylic resin in the solution is 1-10%; the nano-silver is prepared by the following steps of adding a sodium dodecyl sulfate solution to a silver nitrate water solution to obtain mixed liquor, adding crown ether and second reducing agents containing alkali metals to the mixed liquor, and controlling the pH value to be 8-9, thus obtaining the nano-silver. The nano-silver floor has good stability and dispersibility and can fully resist moulds.

Description

technical field [0001] The invention relates to the field of nanometer materials, in particular to a mildewproof and antibacterial nano silver floor. Background technique [0002] Metal nanomaterials are an important branch of nanomaterials, represented by precious metals gold, silver, and copper, among which nano-silver has received the most attention because of its broad application prospects. Nano-silver can be used in many ways: adding a small amount of nano-silver to chemical fiber can improve some properties of chemical fiber products and make it have a strong bactericidal ability; doping an appropriate amount of nano-silver in the silicon oxide film can make The glass coated with this film has certain photoluminescence. Therefore, nano-silver has broad application prospects in the fields of antibacterial materials, high-efficiency catalysts, lubricants, light-absorbing materials, coatings, sensors, conductive pastes, high-performance electrode materials, etc., and ha...
