Problems solved by technology
[0011] Synthetic resin products are more likely to be polluted than glass products. With the help of simple cleaning, bacteria as the source of pollution cannot be removed. Disinfection in boiling water will cause deformation of synthetic resin. In recent years, it has been reported that the bacterial contamination of telephone microphones is serious (please refer to The twelfth collection of papers of Shangzhi University (1991.9) pp67-81)
[0012] But in fact, most ordinary people cannot recognize that synthetic resin products have been polluted
[0013] Recently, the number of glasses wearers has increased rapidly, reaching about 1 / 3 of the total population, and mobile phone holders account for more than 70% of the total population of Korea, but there are no measures or countermeasures against the pollution of such glasses or mobile phones

Abstract
The present invention relates to an antibacterial layer made of metal oxides, an antibacterial film using metal oxides, namely zinc oxide and / or calcium oxide, and a manufacturing method thereof. More specifically, it relates to a method for vacuum coating the exterior of flat panels made of synthetic resin, such as spectacle lenses, mobile phone display screens, food containers, medical containers, etc. Antibacterial film formed by one or two kinds of the group and its manufacturing method.
Description
technical field [0001] The present invention relates to an antibacterial film using metal oxides, ie, zinc oxide and / or calcium oxide, and a method for producing the same. More specifically, it relates to a method for vacuum coating the exterior of flat panels made of synthetic resin, such as spectacle lenses, mobile phone display screens, food containers, medical containers, etc. Antibacterial film formed by one or two kinds of the group and its manufacturing method. Background technique [0002] As substances exhibiting antibacterial properties known so far, there are silver, copper, wood acetic acid, organic chemicals, antibiotics, and the like. However, these materials cannot be used for synthetic resin flat panels, and titanium oxide or metal oxide composites including it exhibiting photocatalytic activity can be used for purposes such as antibacterial and deodorizing due to their photocatalytic activity. It is also widely known (for example, Patent Document 1, etc.)....
