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...
