Description
Technical field:
The utility model relates to a kind of antibiotic glass with anti-fingerprint function.
Background technique:
As touch-control shows that product day is closely universal, people begin to focus on the safe and healthy problem of such product in use,
Related application terminal quotient starts to import antibacterial and antimildew function (Anti-Microbial, AM in the outermost glass cover-plate of product
Glass), or using have antibacterial functions glass protecting label.And method there are two types of the glass with antibacterial functions is made, such as
Shown in Fig. 1.The first is that the film (AM Coating) 101 with antibacterial functions is coated on glass；Be for second using from
Sub- exchange process (Ion-Exchange), by the both side surface of metal ion (AM Ions) the implantation glass with antibacterial functions
102.It is the most large with the patent of anti-microbial coating and product at present, such as: (China) Qinhuangdao Bang Xin green wood Science and Technology Ltd.,
It is primarily due to that component coat film process method is simple and the transparent color of glass, but antibacterial film has the risk being scratched with abrasion, makes glass
Glass surface exposure goes out the part without antibacterial effect, reduces the ability of antibacterial effectiveness；And ion-exchange process is used, antibacterial ion is
Be implanted glass surface, can permanence effective antibacterial, but be easy to cause glass partially faint yellow, need accurate on technological parameter
There are (U.S.) Corning Incorporated, (Germany) Xiao Te group and (China) Ke Lishi material Science and Technology Ltd. in control, current big factory.
In 3C Product using upper, attaches on glass, therefore can be plated on the surface of this antibiotic glass in order to reduce fingerprint greasy dirt
The film of low-surface-energy processed reaches hydrophobic oleophobic effect.The plating of anti-fingerprint (Anti-Fingerprinting, AF) film at present
Mode processed has seven kinds.The first is vacuum evaporation (Vacuum Evaporation)；Second is vacuum/antivacuum spraying
(Vacuum/Atmospheric Spray), precursor material can adopt heating vaporization or atomizing type, wherein precursor material with
Vapor form is heated, and is sprayed at substrate under normal pressure and forms film, (Atmospheric is deposited in also known as normal pressure
Evaporation)；The third is atmospheric pressure plasma spraying (Atmospheric Plasma Spray)；4th kind is infiltration coating
(Dipping Coating)；5th kind is to brush (Brush Coating)；6th kind is rotary coating (Spin Coating)；
7th kind is rotary coating (Spin Coating).Wherein with antivacuum spraying and vacuum deposition method, widely well-known big institute, factory
It uses.
Anti-fingerprint plated film is well-known technique, and basic principle is fluorine (F) polymerization in anti-fingerprint material containing low-surface-energy
Object or fluorinated silane can form silicon-fluorine bond knot (Si-F binding) with silicon (Si) suspension key of substrate surface, can make base
Plate surface reaches hydrophobic oleophobic effect.Anti-fingerprint plated film in antibiotic glass substrate industry general operation process as shown in Fig. 2, head
First using cleaning solvent by antibiotic glass substrate cleaning, then with water stain the 201 of strength gas drying antibiotic glass substrate surface；
The micro- attachment for carrying out to remove antibiotic glass substrate surface again using plasma (Plasma Clean), enables glass surface to expose
Si suspension key 202；Anti-fingerprint film is finally plated, and forms stable Si-F bond 203 in glass and anti-fingerprint film interface.
In addition, about 60 wt% of silica (SiO2) content of general glass, in order to increase the adhesive force and scratch resistance of anti-finger print layer, meeting
The vapor deposition of physical vapour deposition (PVD) (Physical Vapor Deposition, PVD) is first used in glass surface
(Evaporation) or the SiO2 film 204 of sputter (Sputtering) high compactness it then, is coated with anti-finger print layer 205 again.
Ion-exchange antibiotic glass using upper, as shown in figure 3, using antivacuum spraying AF plated film 302, because of AF
The very thin and dense property of film is low, and bacterium can still have antibacterial effect by AF film layer and glass contact 301, glass product, and
The production method of spraying AF eliminates expensive vacuum equipment and processing time, and price is relatively inexpensive, but AF abrasion durability compared with
Difference；And vacuum evaporation AF film layer 305 is used, the SiO2 film 304 of high compactness can be first coated with using PVD in glass surface, is made
The abrasion durability of its AF film layer is preferable, but this SiO2 film can hinder the bacterial reaction on antibacterial ion and surface layer, lead to antibacterial
Efficiency decline.
There has been no patents or technical literature at present partly improves for this, therefore, resistance in order to provide a kind of AF film layer
It is good with property and with permanence antibacterial glass product, it is necessary to development have innovation and the anti-fingerprint antibiotic glass of progressive and
Its manufacturing method.
