Example Embodiment

[0022]Example 1

[0023]Step 1: Disperse 3g of h-BN in a mixture of 90ml of isopropanol and 60ml of deionized water, sonicate the solution for 5h in a water bath at 50℃, then centrifuge the solution at high speed and filter the supernatant. After being washed alternately with water, ethanol and deionized water, they were placed in a drying oven at 80°C for 10 hours to obtain nanosheets. Then add the nanosheets to 120ml of absolute ethanol solution, add 5.1g of zinc acetate after sonication for 5min, sonicate for 50min at 70°C, then cool to 15°C and drop an appropriate amount of KOH ethanol solution into the solution. After it became clear, after stirring for 15 minutes, the solution was centrifuged and washed with absolute ethanol three times and then placed in a vacuum drying oven at 60° C. for 10 hours to obtain ZnO-QDs / h-BN nanosheets.

[0024]Step 2: Add 3.6g of the ZnO-QDs / h-BN nanosheets prepared in Step 1 and 1.08g of sodium lauryl sulfate into 108ml of deionized water, mix well, t...

The sample was washed alternately with absolute ethanol and deionized water and then placed in a drying oven at 73°C for 8 hours to obtain nanosheets. Then add the nanosheets to 135.2ml of absolute ethanol solution, add 5.41g of zinc acetate after sonication for 6min, sonicate for 47min at 68°C, then cool to 12°C and drop an appropriate amount of KOH ethanol solution into the solution to The solution became clear. After stirring for 18 minutes, the solution was centrifuged and washed with absolute ethanol three times, and then placed in a vacuum drying oven at 54°C for 12 hours to obtain ZnO-QDs / h-BN nanosheets.

Abstract

The invention belongs to the field of preparation of anti-fog coatings, and particularly relates to an antibacterial anti-fog coating based on medical goggles and a preparation method of the antibacterial anti-fog coating. The preparation method comprises the following steps of: carrying out ultrasonic dispersion on h-BN to obtain nanosheets; loading ZnO-QDs on the nanosheets by taking zinc acetate as a raw material; taking the ZnO-QDs/h-BN nanosheets, styrene and methacrylic acid as raw materials, taking polymethylacrylic acid- 2-hydroxyethyl ester and lauryl sodium sulfate as auxiliaries, performing modification by using KH-550 to obtain modified ZnO-QDs/h-BN/polystyrene nanospheres; and preparing the composite polystyrene microspheres into a coating, and preparing an anti-fog coating ona substrate by using a dip-coating method. The antibacterial anti-fog coating is a hydrophobic coating, willnot leave spot on the surface, and is long in service life.

Description

technical field [0001] The invention belongs to the field of preparation of anti-fog coatings, in particular to an antibacterial anti-fog coating based on medical goggles and a preparation method thereof. Background technique [0002] With the improvement of living standards, transparent materials have become an inseparable part of people's daily life. Along with these transparent materials, the fogging phenomenon on the surface of the materials has become more and more troublesome to people. The mechanism of the fogging phenomenon is that when the surface temperature of the transparent substrate is lower than the dew point of the surrounding water vapor, the saturated water vapor will be quenched and condensed into water droplets that fall on the surface of the substrate; the most typical example is when the car is driving inside and outside the car. A temperature difference is generated, and the surface temperature of the automobile glass is lower than the dew point tempe...
