Description
Technical field
The invention belongs to glass making techniques fields, and in particular to a kind of preparation method and antibacterial vacuum glass of antibiotic glass
Glass.
Background technique
With the raising of scientific and technological progress and living standards of the people, people are to environmental sanitation pay attention to day by day.Refrigerator, refrigerator-freezer conduct
The heat preservation refrigeration equipment of people's daily life is more and more common, and common freezer door glass is using hollow glass, phase now
For vacuum glass, thickness is big, and heat-proof quality is poor, and vacuum glass only has in the luxury goods such as high-grade wine cabinet a small amount of at present
Using；And antibacterial vacuum glass, research is less, and there has been no related matured products at present.
Antibiotic glass is also known as green glass, is a kind of novel ecological functional material, for improving the ecological environment, keeping the mankind
Health instructs the research and development of correlation function glass material to be of great significance.Inhibit and kill using addition New Inorganic Antibacterial Agents
Bacterium, so that traditional glass product be made to increase new and high technology content.Antibiotic glass both maintained glass material itself have it is saturating
The features such as bright, clean, high mechanical strength, chemical stability are good, and increase killing and inhibit the new function of germ, it is new material
The product that science is combined with microbiology.
The processing and fabricating of antibiotic glass is that antibacterial agent is added on glass carrier, make it have contact-type it is antibacterial, sterilization
Function.Contact-type anti-biotic material, the surface of material is under unconditional normality, it is necessary to have contact antibacterial functions.Therefore, glass
The coating process technology on glass surface is the technological core in antibiotic glass processing.Currently, traditional plate glass plated film side
There are mainly three types of methods, the first is online chemical vapor deposition (CVD) method, and second is on-line spray method, uses both methods
Antibiotic glass is produced, following problems is primarily present: first is that glass space temperature in coating process is excessively high, easily aoxidizing antibacterial agent
Failure limits the using effect and range of antibiotic glass, produces second is that the above method can only carry out plated film in the single side of glass
