Description

Manufacturing method of anti-dazzle anti-reflection antibacterial glass

Technical Field

The invention relates to a manufacturing method of anti-dazzle anti-reflection antibacterial glass.

Background

The anti-dazzle glass is also called non-reflection glass or anti-reflection glass, and is characterized by that the glass raw sheet is undergone the process of special surface treatment, so that it has lower reflection ratio than that of general glass, and does not basically affect light transmission, and the light reflection ratio is reduced from 8% to below 4%. The anti-dazzle glass can reduce the interference of ambient light, improve the visual angle and the brightness of a display picture, and enable an image to be clearer, the color to be more gorgeous and the color to be more saturated, thereby obviously improving the display effect.

The anti-reflection glass used in China at present can basically meet the decoration aspects of glass with low requirement on transmittance. The transmittance of the antireflection glass cannot meet the requirements in liquid crystal display screens, rear projection televisions, mobile phone cover plates, electronic photo frames and instrument display screens which have high transmittance requirements.

Under the situation that the transmission of new coronary pneumonia is severe, the transmission of contact objects is difficult to find, and the display glass with the antibacterial function has great advantages, but the existing display glass does not have the function.

Therefore, there is an urgent need for a glass that can achieve the anti-glare purpose, has a high transmittance, and has an antibacterial effect.

Detailed Description

The invention is further described with reference to the following figures and examples.

Referring to fig. 1-2, a method for manufacturing anti-glare anti-reflection antibacterial glass comprises the following steps:

step 1, pretreating glass 10;

step 2, carrying out film coating treatment on the surface of the glass 10;

the film layer 20 coated in the step 2 has at least two layers, which are a base layer 210 and a titanium dioxide layer 220, respectively, and the titanium dioxide layer 220 is an outer layer.

The titanium dioxide can kill bacteria under photocatalysis, thereby having antibacterial effect. The test results show that the killing rate of the staphylococcus aureus to escherichia coli is 99%.

The principle of photocatalysis:

titanium dioxide is excited by light, and electrons and holes generated by the light are used to participate in redox reactions. When light with energy larger than or equal to the energy gap is irradiated on the titanium dioxide nano-particle, electrons in the valence band are excited to jump to the conduction band, and relatively stable holes are left on the valence band, so that electron-hole pairs are formed. Due to the large number of defects and dangling bonds in the nanomaterial, the defects and dangling bonds can trap electrons or holes and prevent the electrons and holes from recombining again. These trapped electrons and holes diffuse to the surface of the particles, respectively, and a strong redox potential is generated.

The pretreatment in the step 1 comprises the following steps:

step A, cutting the glass 10 into required size by a glass cutting machine or manually;

step B, cleaning the glass 10 for the first time through manpower or cleaning equipment;

c, performing frosting treatment on the glass 10, wherein the frosting treatment can ensure that the surface of the glass is chemically etched to form an anti-glare layer;

d, cleaning the glass 10 for the second time through manpower or cleaning equipment;

e, performing chemical polishing treatment on the glass 10 by using chemical polishing liquid;

and F, carrying out third cleaning on the glass 10 by manpower or cleaning equipment.

Further, the cleaning equipment in the step B or the step D adopts an existing ultrasonic cleaning machine.

Further, in the step C, the frosting treatment is carried out by adopting a spraying process or a soaking process.

The layered structure of the base layer 210 is composed of a first silicon oxide layer 211, a first niobium oxide layer 212, a second silicon oxide layer 213, a second niobium oxide layer 214 and a third silicon oxide layer 215 from inside to outside in sequence, and the titanium dioxide layer 220 is arranged on the third silicon oxide layer 215.

The anti-glare layer has an anti-glare haze of 2-40% and a roughness of 0.05-0.5.

The reflectivity of the film layer 20 is 400-700nm and is less than 0.6% on average.
