The invention relates to the technical field of glass coating treatment liquid, in particular to glass antibacterial coating liquid and a preparation method thereof, and a preparation method of antibacterial coated glass.
[ background of the invention ]
The antibacterial coated glass, namely the antibacterial glass, is glass treated by a special antibacterial process, is widely applied to the aspects of medical appliance glass, touch screens and the like, and can reduce the adhesion of bacteria on the surface of the glass by killing or killing most of bacteria. The method for forming the antibacterial coated glass at present mainly uses a nano silver system coating on the surface of the glass, thereby achieving the purpose of killing bacteria. And coating titanium oxide on the surface of the glass so as to achieve the aim of sterilization. The application of the nano silver antibacterial material on glass can cause the following problems: 1. the metal ions are easily oxidized and discolored by air, and the display effect is influenced. 2. The principle is that the silver ions slowly dissolve out to achieve the aims of antibiosis and sterilization, but the silver ions can lose the effect with the lapse of time. 3. The countries of the European Union, etc. forbid the use of nano silver as antibacterial products, and can inquire the relevant information of the European countries, including the United states environmental protection agency. Because silver ions are released continuously, the nano-silver antibacterial agent can be accumulated to cause pathological changes if being absorbed by internal organs of a human body, and can never be discharged out of the body, thereby greatly harming the health of the human body. The titanium oxide antibacterial material applied to glass has the following problems: 1. titanium oxide antibacterial is to decompose organic matters such as bacteria by exciting strong oxidizing power by ultraviolet irradiation, and the antibacterial effect of titanium oxide cannot be achieved in a room or an environment without direct sunlight. 2. Titanium oxide has a high refractive index, and when it is used for glass having a refractive index of about 1.5, the display effect is impaired
