[0021] The preparation method of coating member 10 of the present invention, it comprises the steps:

[0022] (1) Add the antibacterial material to the organic solvent to disperse the colloid. The antibacterial material contains at least one of nano-silver ions, nano-copper ions, and at least one of nano-titanium dioxide, nano-zinc oxide, and nano-copper oxide. The organic solvent is preferably ethanol, but not limited to ethanol. The mass ratio of the antibacterial material to the organic solvent in the colloid is 1:1-1:100.

[0023] (2) Mix the above-mentioned colloid with silicon oxide having nanoscale pores, remove the organic solvent, and perform heat treatment to obtain a nanocomposite material. The heat treatment is at 300-500° C. for 0.5-5 hours. The antibacterial material in the nanocomposite material is loaded on silicon oxide, which can greatly improve the utilization rate of the antibacterial material. The mass of the antibacterial material contained in the col...

Embodiment 1

[0032] The antibacterial material is added into an organic solvent to disperse the colloid. The antibacterial material contains nano-silver ions and nano-titanium dioxide. The organic solvent is ethanol, and the mass ratio of the antibacterial material to the organic solvent is 1:50.

[0033] The above colloid was composited with silicon oxide with nanoscale pores, and the organic solvent was evaporated to remove the organic solvent. Then, the temperature was raised to 400°C in a muffle furnace for 2 hours to prepare a nanocomposite material, in which the mass of the antibacterial material was 2.0% of the mass of the silicon oxide.

[0034] The material of the substrate 11 used in this embodiment is glass.

[0035] Adopt the method for evaporative coating, deposit nano-composite material on the surface of base material 11 to form an antibacterial layer 13, the vacuum tightness in the vacuum evaporation machine is set to be 5 * 10 -5 torr, the temperature is 80° C., and the com...

Embodiment 2

[0043] The antibacterial material is added into an organic solvent to disperse the colloid. The antibacterial material contains nano-silver ions and nano-titanium dioxide. The organic solvent is ethanol, and the mass ratio of the antibacterial material to the organic solvent is 1:100.

[0044] The above colloid was combined with silicon oxide with nanoscale pores, and the organic solvent was evaporated to remove the organic solvent. Then, the temperature was raised to 350 ° C in a muffle furnace for 2.5 hours to prepare a nanocomposite material, in which the mass of the antibacterial material was 2.5% of the mass of the silicon oxide.

[0045] The material of the substrate 11 used in this embodiment is glass.

[0046]Adopt the method for evaporative coating, deposit nano-composite material on the surface of base material 11 to form an antibacterial layer 13, the vacuum tightness in the vacuum evaporation machine is set to be 5 * 10 -5 torr, the temperature is 70°C, and the com...

Abstract

A coated member comprises a substrate, an antibiotic layer formed on the surface of the substrate, and an anti-fingerprint layer formed on the surface of the antibiotic layer, the antibiotic layer contains silicon oxide having nanometer pores and an antibiotic material loaded on silicon oxide, the antibiotic material contains at least one of nanometer silver ions and nanometer copper ions, and at least one of nanometer titanium dioxide, nanometer zinc oxide and nanometer copper oxide, the anti-fingerprint layer is a perfluoropolyether silane layer, and the thickness of the anti-fingerprint can realize the dissociation of antibiotic material in the antibiotic layer to the surface of the anti-fingerprint layer. The invention also provides a making method of the coated member. The surface of the coated member has good anti-pollution and antibiosis effects.

Description

technical field [0001] The invention relates to a coating piece and a preparation method thereof. Background technique [0002] Currently, smart phones and tablet computers are favored by more and more consumers. When using a smart phone or a tablet computer, the user often needs to touch the touch screen of the smart phone or tablet computer with fingers, so that various dirt such as sweat and oil on the fingers are easily transferred and adhered to the touch screen. Various stains form on the surface of the touch screen. In addition, if the stains on the touch screen cannot be cleaned and removed in time, microorganisms such as bacteria will easily breed. Contents of the invention [0003] In view of this, it is necessary to provide a coating with antifouling and antibacterial surface. [0004] In addition, it is also necessary to provide a method for preparing the above-mentioned coated piece. [0005] A kind of coating part, it comprises base material, the antibact...
