Abstract

The invention relates to the field of nano materials, and particularly relates to a nano silver decoration laminated board. The nano silver decoration laminated board is formed by bonding a decoration single board and a base material by a bonding agent layer; the decoration single board and the base material are formed by impregnating by a nanometer aqueous solution; the bonding agent layer contains a nanometer silver substance; the decoration single board and the base material are engineering wood; the nanometer silver aqueous solution is formed by taking deionized water as a solvent, dissolving nanometer silver as solute into the deionized water, taking acrylic resin as a complexing agent and dissolving a stabilizing agent into the deionized water, and meanwhile adding a dispersion agent and a first reducing agent; the concentration of nanometer silver in the bonding agent is 75-150ppm; the mass content of flour in the solution is 18-45%; environment-friendly glue comprises 40-80 parts solid with 40-55%bacrylic resin emulsion, 20-40 parts of acrylic resin powder, 5-20 parts of solid with 40-60%EVA emulsion as well as 7-13 parts of chlorinated polypropylene or polyolefin substrate adhesion promoter. The nano silver decoration laminated board provided by the invention is good in stability and dispersion, and can fully resist mildew.

Description

technical field [0001] The invention relates to the field of nanometer materials, in particular to a nanometer silver decorative veneer. 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 has become a fu...
