The invention relates to the field of nano materials and particularly relates to a mildew-resistant and antibacterial nano-silver decorative laminated board. The mildew-resistant and antibacterial nano-silver decorative laminated board is formed by a decorative veneer and a base material which are bonded by an adhesive layer, wherein the decorative veneer and the base material are dipped by nano aqueous solution; the adhesive layer contains nano-silver substances; the decorative veneer and the base material are made of technical wood; the nano-silver aqueous solution is formed by adopting deionized water as a solvent, adopting nano silver as solute to be dissolved into the deionized water, adopting acrylic resin as a complexing agent and a stabilizing agent to be dissolved into the deionized water, and adding a dispersing agent and a first reducing agent simultaneously; the concentration of nano silver in the adhesive is 75-150ppm; the mass content of flour in solution is 18-45%; environmental-friendly glue comprises the following materials in parts by weight: 40-80 parts of acrylic resin solution emulsion with the solid content being 40-55%, 20-40 parts of acrylic resin powder, 5-20 parts of EVA emulsion with the solid content being 40-60%, 1-4 parts of dibutyl phthalate and 7-13 parts of chlorinated polypropylene or polyolefin substrate adhesive-force promoter. The mildew-resistant and antibacterial nano-silver decorative laminated board has the advantages that the stability and the dispersibility are good and the mildew can be fully resisted.

The invention discloses water-based environment-friendly color-changing nail polish which comprises the following components: 40.0-50.0 parts by weight of water-based aliphatic polyurethane, 35.0-45.0parts by weight of a water-based aliphatic polyurethane acrylic acid copolymer, 3.0 to 6.0 parts by weight of a reversible temperature-sensitive color-changing material, 3.0 to 6.0 parts by weight ofa reversible photo-sensitive color-changing material, 0-2.0 parts of a pigment, 0.1-0.5 part of a wetting agent, 1.0-2.0 parts by weight of a thickening agent, 0.5-1.0 part of an adhesion promoter, 0.5-1.0 part of a preservative, 3.0-5.0 parts of a coalescing agent, 0-2.0 parts of other additives and the balance of deionized water. The reversible color-changing powder and other components are lowin odor and harmless to human health, environment-friendly, strong in adhesive force and long in retention time on nails, and can be used for blending various colors, and different colors can be changed along with different temperatures and different intensity of light, and the reversible temperature-sensitive color-changing material and the photo-sensitive color-changing material are good in stability, not easy to fade, and capable of maintaining a bright color for a long time.

The invention discloses nano conductive ink. The nano conductive ink is prepared from the following components: 60-80 parts of conductive metallic packing, 0.1-5 parts of silver nanoparticles 2-50nm in particle size, 1-12 parts of high molecular organic resin, 0.5-5 parts of an adhesion accelerant, 0.1-2 parts of a flatting agent, 0.1-2 parts of an antifoaming agent and 10-25 parts of an organic solvent. The invention also discloses a preparation method of the nano conductive ink, an RFID antenna of the nano conductive ink, and a preparation method of an RFID electronic tag. The nano conductive ink has the beneficial effects that the RFID antenna printed by using the nano conductive ink is ultrathin and uniform in thickness and has good conductivity and adhesive force, also consumption ofthe conductive ink can be reduced by reducing the thickness of the RFID antenna, and the cost is greatly reduced.

The invention provides high-adhesion wear-resistant UV-LED printing ink, which is prepared from 41 to 46 parts of high-functionality polyurethane acrylate, 13 to 18 parts of adhesion promoter, 30 to 35 parts of cyclopentene ethyl isocyanuric acid triacrylate, 6 to 12 parts of photoinitiator, 2 to 4 parts of auxiliary agent and 3 to 5 parts of filler. The high-functionality polyurethane acrylate is taken as a prepolymer, thecyclopentene ethyl isocyanuric acid triacrylate is taken as an active monomer, the adhesion promoter is added as a modifier, then the photoinitiator, the auxiliary agent and the filler are added, so that the prepared UV-LED printing ink has high friction resistance and adhesion, and the service life pf a keyboard smeared with the UV-LED printing ink can be prolonged.
