Description
Technical field
The present invention relates to hydrophilic antifogging coating compositions of a kind of photo-thermal dual curable and preparation method thereof, and it is double to belong to photo-thermal
The coating material solidified field of weight.
Background technique
Vapor in air will condense into small drop and mist formation when temperature is lower than dew point.It is this undesirable
Influence frequently occurs in window, bathroom mirror, glasses, swimming and Lunettes, windshield, optical instrument camera lens, car light, refers to
Showing lamp, agricultural film etc., these live on the transparent material being closely related with us.Transparent material surface water droplet atomization as a result, not only
Light transmittance decline influences vision, generates harm sometimes, such as when droplet condenses in such as infrared optics microscope rigorous analysis
When on the lens surface of instrument, the accuracy of analysis can be reduced.And when droplet condenses on solar battery light-transmitting plate, it causes
Make the reduction of solar absorption efficiency, so that being unfavorable for solar cell device gives full play to due effect.
In order to solve these problems, can generally hydrophobic or hydrophilic treated be carried out to material surface.Hydrophobic common perfluorinated resin
Class, one side price is higher, and on the other hand the resinoid is generally softer, wears no resistance, while its hydrophobic property also leads to its table
Face easily adsorbs greasy dirt and dust, the effect not reached requirement instead.And organic hydrophilic coating price itself is inexpensively, it can also
Its wearability is improved by some modifications.Using organic hydrophilic coating compared to hydrophobic coating processing method not only construction party
Just, and it is cheap.
It is concentrated mainly on super hydrophilic research both at home and abroad now, as coating surface introducing can form the group such as carboxylic of hydrogen bond
Base, amino, sulfydryl, hydroxyl or some ionic groups: carboxylate radical, sulfonate radical, ammonium root, phosphate radical etc., when these groups of introducing
Or when ion, the surface of coating reaches super hydrophilic state, sprawls after moisture condensation in substrate surface height, forms one layer
Even moisture film eliminates tiny drops of water and achievees the purpose that antifog to the diffusing reflection of light.Super hydrophilic approach master is prepared at present
If passing through physical blending, Chemical modification, chemical bond connection.Anti-fog coating currently on the market continue anti-fog performance with it is resistance to
Mill performance can not balance, and after a period of use, anti-fog performance just declines obviously.
Chinese patent CN 102795791A discloses a kind of wear-resisting super hydrophilic antireflecting coating, and the coating by depositing repeatedly
Diallyl dimethyl ammoniumchloride and kayexalate prepare 5~20 layers of double-layer structure, then poly- by deposition repeatedly
Diallyldimethylammonium chloride and the SiO for being 10~40nm containing partial size2The suspension of nano spherical particle prepares 3~8 layers
Double-layer structure, then 100~300s system is quenched by 100~140 DEG C of hydro-thermal process and in 600~800 DEG C of Muffle furnace
Coating needed for obtaining.Although coating made from this method can reach the high rigidity of 5H and water contact angle also very little, step is complicated,
Lasting anti-fog properties general, energy consumption is high, only has the user of special high request suitable performance.
Domestic patent CN102086348A discloses a kind of preparation side of urethane cures acrylate anti-fog coating
Method, the coating is by hydrophilic acrylic resin, enclosed type polyethers isocyanate curing agent and catalyst dibutyltin dilaurylate
Composition.The coating hardness is greater than 2H, and wear-resisting property is good, but lasting anti-fog performance is general, and solidification process needs the time longer, and needs
Stage curing (50~120 DEG C), the process is more complicated.
To overcome traditional anti-fog coating on the market to continue the contradiction of anti-fog performance and wear-resisting property, the present invention discloses a kind of light
The hydrophilic antifogging coating of hot dual cure.The coating passes through heat cure first, uses photocuring, the coating after solidification, parent later
Aqueous splendid and lasting anti-fog performance is outstanding, while will not lose wear-resisting property, therefore overcome the one of anti-fog coating on the market
A little drawbacks are very suitable to do the field that vehicle window, bathroom mirror etc. have antifog requirement.

Three, wear-resisting property
Using 0000# steel wool, 300g power, one is denoted as once back and forth, and the number scratched occurs in recording surface.
Appraisal procedure: after the friction of certain number, whether observation coating has scratch, is resistant to when recording without scratch
Most Rubbing numbers.
Four, initial stage hydrophilic angle
4 μ L deionized waters are dripped in the specimen surface being cured, are measured within the scope of 20~25 DEG C with contact angle tester.
Five, continue hydrophilic angle
The sample being cured is put into deionized water and impregnates 100h, is measured after drying with contact angle measurement.
By the test result of Examples 1 to 5 and comparative example 1~8, including attachment, pencil hardness, wear-resisting, initial stage hydrophilic angle
Persistently hydrophilic angle is summarized as follows table 3.
5 embodiment and comparative example test result of table
As shown in Table 5, the hardness of embodiment is higher than comparative example, because the embodiment of the present invention uses dual cure,
Further photocuring on the basis of heat cure, crosslink density are significantly larger than individual curing mode, and performance is embodied in hardness and resistance to
On mill, more single curing mode has promotion；In addition, in comparative example, the hardness of photocuring system and wear-resisting micro- it is better than heat cure
System, because its crosslink density is higher than heat cure；Comparative example 7 and 8 and example 1 group point are consistent, but curing mode is different, right
Ratio 7 is only with heat cure, and comparative example 8 is only with photocuring, therefore crosslink density is far away from dual cure, aspect of performance hardness
It is wear-resisting not reach requirement, and protracted hydrophilicity can be also good without embodiment 1.It is close in the early stage from the point of view of Comprehensive Correlation example and embodiment
Water aspect of performance, comparative example and embodiment difference are not that too greatly, because of the addition of surface reactive material, can reduce parent well
Water angle plays excellent anti-fog effect, but at persistently hydrophilic aspect, the hydrophilic angle of embodiment will be lower than comparative example, because
Polymerisable surfactant has been connected in main structure by cross-linking reaction, in addition the crosslink density of superelevation, cause even across
Prolonged water immersion will not steep；And comparative example is impregnated by long-time, hydrophilic angle can increase significantly, continue anti-fog properties
Can be poor, effect of the invention is not achieved in comprehensive performance.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.
