Problems solved by technology

But the glass is used in the construction field, which is very different from the touch screen
[0008] At present, the coated glass used in touch screens and other fields is mainly anti-reflection glass, that is, coated glass that improves the light transmission performance of glass, but in these fields, especially in the field of touch screens, there are still antibacterial performance requirements and anti-fingerprint requirements, there is currently no such coated glass that can meet such requirements at the same time, so it is urgent to provide a glass with antibacterial, anti-fingerprint and anti-reflection triple functions

Embodiment 1

[0058] Prepare SiO as described above 2 -TiO 2 -Ag 2 O-fluorosilane sol-gel solution, SiO in this example 2 -TiO 2 -Ag 2 The O-fluorosilane sol-gel solution is calculated by volume percentage, including: 90% of silica sol (using acid catalysis as raw material to prepare tetraethyl orthosilicate, wherein the volume percentage of silicon dioxide in silica sol content is 3.0%), titanium dioxide sol 3.5% (prepared by acid catalysis with tetra-n-butyl titanate as raw material, wherein the volume percentage of titanium dioxide in titanium dioxide sol is 3.0%), fluorosilane sol 3.5% (raw material trimethyl Fluorosilane, wherein the volume percentage of trimethylfluorosilane in the fluorosilane sol is 1%), silver nitrate solution 2.0% (wherein the weight percentage of silver nitrate in the silver nitrate solution is by Ag 2 The specific weight percentage of O oxide is 5.0%) and the stabilizer solution 1.0% (the raw material silane coupling agent, wherein the weight percentage of ...

Embodiment 2

[0061] SiO in this example 2 -TiO 2 -Ag 2 The O-fluorosilane sol-gel solution is the same as in Example 1.

[0062] In this embodiment, the glass with antibacterial, anti-fingerprint and anti-reflection triple effects is prepared by spraying method. The method is as follows: use a spray gun to spray SiO 2 -TiO 2 -Ag 2 The O-fluorosilane sol-gel solution was sprayed onto the glass substrate at a uniform speed up, down, left, and right to obtain a glass substrate with a single-layer film; after the film layer was naturally dried, the glass substrate with a single-layer film was placed in an oven at 250°C for 15 minutes to obtain The thickness of the single-layer film is 100nm, which has the triple effect of antibacterial, anti-fingerprint and anti-reflection.

Abstract

The invention discloses a glass with antibacterial, anti-fingerprint and transmission increasing triple efficacy and a preparation method thereof. The glass includes a glass substrate and a monolayer film formed on at least one surface of the glass substrate. The monolayer film is a porous network structure SiO2-TiO2-Ag2O-fluoroalkyl silane composite membrane formed by SiO2, TiO2, Ag2O and fluoroalkyl silane. The preparation method of the glass provided by the invention comprises: letting an SiO2-TiO2-Ag2O-fluoroalkyl silane sol-gel solution form on the glass substrate by Czochralski method, spraying method, roller coating method, spin-coating method or spray coating method, and conducting drying to obtain the glass with antibacterial, anti-fingerprint and transmission increasing triple efficacy. The existence of SiO2 and TiO2 endows the glass with the transmission increasing function, the existence of Ag2O endows the glass with the antibacterial function, and the existence of fluoroalkyl silane endows the glass with the anti-fingerprint function. Therefore, the glass provided by the invention has antibacterial, anti-fingerprint and transmission increasing triple efficacy.

Description

technical field [0001] The invention relates to the technical field of coated glass, in particular to a glass with triple functions of antibacterial, anti-fingerprint and anti-reflection and a preparation method thereof. Background technique [0002] Touchscreens were a technology that emerged in academic and corporate research laboratories in the late 1960s. Today, many people still think that touch screens are cutting-edge technology, but in fact we have been using touch screens for 25 years, and there are more than ten kinds of touch screen technologies used in mobile phones, personal computers and monitors today. Some of these touch technologies are resistive, capacitive, surface acoustic wave, and infrared matrix. [0003] Among them, surface acoustic wave technology can provide good image clarity, because it uses a pure glass structure, which can provide excellent image clarity, resolution and high light transmission. However, the light source transmitted by pure gla...
