Abstract

The invention relates to the field of antibacterial glass, in particular to an anti-fingerprint antibacterial glass. The anti-fingerprint antibacterial glass comprises an original glass sheet and an anti-fingerprint antibacterial layer which coats the upper surface of the original glass sheet, the anti-fingerprint antibacterial layer is formed by coating an antibacterial composition, and the antibacterial composition is prepared from, by mass, 2 to 10 percent of organic modified acrylic resin, 60 to 80 percent of methylbenzene, 10 to 30 percent of dichloromethane and 1 to 8 percent of fluorinated silver-loaded carbon nanohorn ethanol dispersion liquid. The fluorinated silver-loaded carbon nanohorn ethanol dispersion liquid is prepared on the basis of carboxylated single-walled carbon nanohorns and has antibacterial, antifouling and anti-fingerprint effects, and the antibacterial effect reaches 99% or above. According to the antibacterial glass, self-assembly of the antibacterial nano particles and the synergistic effect of the components are induced through solvent volatilization, so that the antibacterial glass has an excellent anti-fingerprint effect and outstanding antibacterial performance, and breeding of bacteria on the surface can be effectively inhibited.

Description

technical field [0001] The invention relates to the field of antibacterial glass, in particular to an antifingerprint antibacterial glass. Background technique [0002] In recent years, due to the improvement of people's living standards, people pay more and more attention to environmental sanitation. As the application of touch interaction technology becomes more and more extensive, users will come into contact with the screen of touch devices more frequently, which may cause bacteria, fungi, viruses, etc. to spread before users to a greater extent, and the demand for antibacterial protective materials and products is increasing. Relevant application terminal manufacturers have begun to introduce antibacterial and anti-mildew function cover plates or glass products on the outermost layer of touch products. [0003] Antibacterial glass, called green glass, is a new type of ecological functional material, which uses the addition of inorganic antibacterial agents to inhibit a...
