Embodiment 1

[0053] Prepare antibacterial glass, the method is as follows:

[0054] Step 1: Take a piece of 4*4cm ordinary glass, soak it in 5% NaOH solution for 12 hours, then ultrasonically wash it in acetone, absolute ethanol and deionized water for 15 minutes, then dry it at room temperature and set it aside.

[0055] Step 2: Prepare a colorless nano-silver solution composite solution. Weigh 50 mL of commercially available colorless nano-silver solution and mix it with PEG-2000 at a mass ratio of 15:1, wherein the silver ion content is 5%. Brush the prepared colorless nano-silver solution composite solution evenly on the glass to form a first coating of 1 μm, and then bake it at 120°C for 30 minutes, and set it aside.

[0056] Step 3: The glass in the above step 2 is painted with UV resin containing 5% ethoxy-modified TMPTA, and cured by ultraviolet radiation to obtain a transparent and dense second coating. The ultraviolet irradiation curing adopts conventional ultraviolet irradiati...

Embodiment 2

[0058] Prepare antibacterial glass, the method is as follows:

[0059] Step 1: Take a piece of 4*4cm ordinary glass, soak it in 5% NaOH solution for 12 hours, then ultrasonically wash it in acetone, absolute ethanol and deionized water for 15 minutes, then dry it at room temperature and set it aside.

[0060] Step 2: Prepare a colorless nano-silver solution composite solution. Weigh 50 mL of commercially available colorless nano-silver solution and mix it with PEG-2000 at a mass ratio of 20:1. Brush the prepared colorless nano-silver solution composite solution evenly on the glass to form the first coating of 5 μm, and then bake it at 120°C for 30 minutes, and set it aside.

[0061] Step 3: Paint the glass in the above step 2 with a UV resin containing 10% ethoxy-modified TMPTA, and cure with ultraviolet radiation to obtain a transparent and dense second coating. The ultraviolet irradiation curing adopts conventional ultraviolet irradiation conditions.

Embodiment 3

[0063] Prepare antibacterial glass, the method is as follows:

[0064] Step 1: Take a 4*4cm piece of ordinary glass, soak it in 5% NaOH solution for 12 hours, then ultrasonically wash it in acetone, absolute ethanol and deionized water for 10 minutes, then dry it at room temperature and set it aside.

[0065] Step 2: Prepare a colorless nano-silver solution composite solution. Weigh 50 mL of commercially available colorless nano-silver solution and mix it with PEG-2000 at a mass ratio of 5:1. Brush the prepared colorless nano-silver solution composite solution evenly on the glass to form a first coating of 8 μm, and then bake it at 120°C for 30 minutes, and set it aside.

[0066] Step 3: Paint the glass in the above step 2 with a UV resin containing 15% ethoxy-modified TMPTA, and cure with ultraviolet radiation to obtain a transparent and dense second coating. The ultraviolet irradiation curing adopts conventional ultraviolet irradiation conditions.

Abstract

The invention relates to antibacterial glass and a preparation method of the antibacterial glass. The antibacterial glass comprises a glass substrate, wherein a transparent coating is arranged on at least one lateral surface of the glass substrate, the transparent coating comprises a first coating layer and a second coating layer, the first coating layer is formed by baking a mixed solution of a colorless nano-silver solution and polyethylene glycol after applying onto one lateral surface of the glass substrate, the second coating is formed by carrying out ultraviolet curing on a mixture of ethoxylated trimethylolpropane triacrylate and UV resin, and the second coating is located at the outermost layer of the antimicrobial glass. The antibacterial glass is colorless, transparent, long-lasting in antibacterial effect, resistant to ultraviolet radiation, scrub-resistant, good in weather resistance and wide in practical range; the manufacturing method of the antibacterial glass is short in operation process, high in production efficiency, low in cost, long-lasting in effect, and good in market application prospects.

Description

technical field [0001] The invention relates to the technical field of glass coating, in particular to an antibacterial glass and a preparation method thereof. Background technique [0002] Antibacterial technology has always been an effective means to resist harmful bacteria from invading humans. Antibacterial glass is not harmful to the environment and human body, so it is called "green glass". As a kind of functional glass, it not only has the original functions of transparency, shielding and wear resistance, but also adds new functions of antibacterial and sterilizing. It can be widely used in medical treatment, food, electrical appliances, mobile phones, glasses, etc. place and industry. [0003] There are already patents and products related to antibacterial glass at home and abroad. For example, in 2014, Corning launched a new "antibacterial Gorilla Glass". The glass is a glass product obtained by doping a small amount of silver ions into the glass surface in a mol...
