Abstract
The invention discloses a kind of antifog anti-droplet coating film on glass agent of hydrophily to be mixed by ethyl orthosilicate, dehydrated alcohol, cesium hydroxide and water, the ethyl orthosilicate and water molar ratio are 1:2, ethyl orthosilicate and cesium hydroxide molar ratio are 8 ~ 10:1, and dehydrated alcohol is solvent.Film coating agent of the present invention can form physics hydrophilic layer in glass surface, and not needing ultraviolet light irradiation also has ultrahydrophilic, and antifog anti-droplet, transparency are high, and the mechanical strengths such as film layer scratch-resistant and antistripping after not influencing sight and plated film greatly improve.The present invention is used suitable for automotive windshield, outside rear-view mirror and glasses, glass helmet mirror, engineering glass, photovoltaic glass, glass-mirror etc..
Description
Technical field
It is especially a kind of for the antifog anti-droplet parent of glass surface the present invention relates to the antifog anti-droplet technology of glass hydrophily
Aqueous film coating agent and film plating process.
Technical background
Automobile wind shield glass, automobile rearview mirror, glass helmet mirror, glass spectacle lens, mirror surface, the glass on photovoltaic module
Deng, due to contact rainwater, mist, steam etc. in air, these substrate surfaces can all be accumulated by water droplet haze, droplet becomes mould
It pastes unclear.Especially because rain, mist, other steam influence mirror surface sight when driving, and it is too numerous to mention that traffic accident example occurs.
There are many anti-misty rain coating liquids at present, most of is all repellency (hydrophobicity), although there is certain anti-misty rain function, reprimand
Water effect is unobvious, is detained droplet, droplet seriously affects specular light line reflection or perspective, to affect sight (such as vapour
Exterior mirror, windshield, helmet mirror), cause driving accident.And hydrophily coating liquid can be formed in substrate surface it is hydrophilic
Property film, this layer film is minimum to water contact angle, can make that glass surface does not haze, water does not form water droplet and forms large area moisture film
It is automatic to slide or tile downwards, antifog anti-droplet.It is current it is hydrophilic have TiO 2 coating film liquid, main improvement is in glass
The reduction diffusing reflection of glass and increase light transmittance, and have the following deficiencies: that 1, its hydrophily needs ultraviolet light to excite, at night
Evening and rainy days can not play a role；2, mechanical strength is not high, and scratch-resistant and peeling resistance be not strong.In addition hydrophilic plated film
Liquid is there are also acrylic compounds, polyurethanes, the antifog coating liquid of epoxies, these coating liquids form waterproof antifog film the disadvantage is that water suction is molten
It is swollen or outflow with water.
Summary of the invention
The antifog anti-droplet coating film on glass agent of hydrophily of the present invention is for repellency in the prior art and hydrophily plated film
Defect present in liquid or deficiency, providing a kind of can make water not form water droplet and form large area moisture film and slide downwards automatically or flat
Paving, not only it is siliceous to form but also not need ultraviolet light irradiation, long action time, the hydrophily of plated film high mechanical strength for antifog anti-droplet
Film coating agent and film plating process.
The taken technical solution of the technical problem to be solved in the present invention is as follows: a kind of antifog anti-droplet coating film on glass of hydrophily
Agent is mixed by ethyl orthosilicate, dehydrated alcohol, cesium hydroxide and water, and the ethyl orthosilicate and water molar ratio are 1:2, just
Silester and cesium hydroxide molar ratio are 8 ~ 10:1, and dehydrated alcohol is solvent.
The present invention antifog anti-droplet coating film on glass agent preparation method of hydrophily described further is to contain cesium hydroxide second
Ethyl orthosilicate partial hydrolysis is condensed in alcohol.
Representative molecular structure is as follows:
Film coating agent is coated in clean and dry by the present invention antifog anti-droplet coating film on glass agent film plating process of hydrophily described further
Glass surface to be coated after waiting alcohol to volatilize, stands reaction in air, then cooling after 700 DEG C of temperature are sintered.
Beneficial effects of the present invention: the antifog anti-droplet coating film on glass agent of hydrophily provided by the invention can be in glass baseplate
Upper formation layer of transparent film, water or steam do not form water droplet on film, but form large area water skiing group, connect to water
Feeler is 0 ° to 20 °, substrate surface may be implemented downward water skiing or tiling automatically when having water to wash away, not due to coating liquid component
Together, so that the physics hydrophilic layer that coating liquid surface is formed, not needing ultraviolet light irradiation also has a ultrahydrophilic, antifog anti-droplet,
Transparency is high, and the mechanical strengths such as film layer scratch-resistant and antistripping after not influencing sight and plated film greatly improve.The present invention is applicable in
In automotive windshield, outside rear-view mirror and glasses, glass helmet mirror, engineering glass, photovoltaic glass, glass-mirror etc..
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, below by specific embodiment come into
One step the present invention is described in detail.
Several different hydrophily silicon resin copolymers are produced respectively before specific implementation:
Embodiment 1: 728.34g dehydrated alcohol is weighed in 2000ml plastic flask, starts stirring, is slowly added into 27.33g hydrogen-oxygen
Change caesium, dissolve it sufficiently, 208g ethyl orthosilicate is being added dropwise, then 36 grams of deionized waters are added dropwise, is continuing stirring 2 hours, product
The as antifog anti-droplet coating film on glass agent of hydrophily.
Embodiment 2: 721.84g dehydrated alcohol is weighed in 2000ml plastic flask, stirring is started, is slowly added into 34.16g
Cesium hydroxide dissolves it sufficiently, 208g ethyl orthosilicate is being added dropwise, then 36 grams of deionized waters are added dropwise, is continuing stirring 2 hours,
Product is that hydrophily is antifog, anti-droplet coating film on glass agent.
Testing substrates use 24 × 40mm glass slide, and glass slide is impregnated by the concentrated sulfuric acid-potassium chromate washing lotion, rinsed with clear water
It completely dries, continues to coat with embodiment 1,2 coating liquid of embodiment respectively, it is clean to ethyl alcohol volatilization, it is small to empty reaction 2 in gas
When, it is sintered 10 minutes putting into be warming up in 700 DEG C of Muffle furnaces, takes out cooling.The test of contact angle is using Japan's consonance
Interface science company CA-Z150 type contact angle measurement measures.
Evaluation of result:
It uses the glass water droplet contact angle of antifog, the anti-droplet coating film on glass agent plated film of 1 synthesis hydrophilic of embodiment for 10 °, uses mouth
Ba Haqi, anti-fog effect is obvious, with spray bottle spray water, glass surface smooth.
It uses the glass water droplet contact angle of antifog, the anti-droplet coating film on glass agent plated film of 2 synthesis hydrophilic of embodiment for 5 °, uses
Mouth is breathed out, and anti-fog effect is obvious, with spray bottle spray water, glass surface smooth.
In practical applications, using the automotive rear-view of the glass production of the antifog anti-droplet coating film on glass agent plated film of hydrophily
Mirror, in the rainy day, rearview mirror sight is clear, and no water droplet for influencing sight is formed.Even if comparing low humidity in temperature, breathes out and generate droplet
It can dissipate rapidly.And it is washed away repeatedly through rainwater, lasts.
It is hereby stated that described above facilitate those skilled in the art understand that the invention, but not limit the present invention
The protection scope of creation.Any same replacement described above, modification are improved without disengaging the invention substantive content
Or delete numerous conform to the principle of simplicity and the implementation that carries out, each fall within the protection scope of the invention.
