Description
Technical field
Hydrophilic antifogging coating composition that the present invention relates to a kind of photo-thermal dual curable and preparation method thereof, belongs to photo-thermal double
The coating material solidified field of weight.
Background technology
Steam in air, when temperature is less than dew point, will condense into small drop and mist formation.This bad
Impact frequently occurs in window, bathroom mirror, glasses, swimming and Lunettes, windshield, optical instrument camera lens, car light, refers to
These are lived on the transparent material being closely related with us to show lamp, agricultural film etc..The result of transparent material surface water droplet atomization, not only
Light transmittance declines affects vision, produces harm sometimes, such as, condenses in such as rigorous analysiss such as infrared optics microscopes when droplet
Time on the lens surface of instrument, its accuracy analyzed can reduce.And when droplet condenses on solaode light-passing board, cause
Make solar absorption efficiency reduce, thus be unfavorable for that solar cell device gives full play to due effect.
In order to solve these problems, typically material surface can be carried out hydrophobic or hydrophilic treated.Hydrophobic conventional perfluorinated resin
Class, on the one hand price is higher, and on the other hand this resinoid is the softest, wears no resistance, and its hydrophobic property also causes its table simultaneously
Face easily adsorbs greasy dirt and dust, does not reaches the effect of requirement on the contrary.And the price of organic hydrophilic coating own is inexpensively, it is possible to
Its wearability is improved by some modifications.Use organic hydrophilic coating compared to hydrophobic coating processing method not only construction party
Just, and 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 introducing these groups
Or during ion, the surface of coating reaches super hydrophilic state, sprawls at substrate surface height after moisture condensation, form one layer all
Even moisture film, eliminates the purpose that tiny drops of water reaches antifog to the diffuse-reflectance of light.Prepare super hydrophilic approach master at present
If by physical blending, Chemical modification, chemical bond connection.Antifogging coating in the market continues anti-fog performance with resistance to
Mill performance cannot balance, and after using a period of time, anti-fog performance just declines substantially.
Chinese patent CN 102795791A discloses a kind of wear-resisting super hydrophilic antireflecting coating, and this coating is by repeatedly depositing
Diallyl dimethyl ammoniumchloride and kayexalate prepare the double-decker of 5～20 layers, more poly-by deposition repeatedly
Diallyldimethylammonium chloride and containing particle diameter be 10～40nm SiO2The suspension of nano spherical particle prepares 3～8 layers
Double-decker, then by the hydrothermal treatment consists of 100～140 DEG C and the 100～300s systems that quench in the Muffle furnace of 600～800 DEG C
Coating needed for.Although the coating that the method prepares can reach the high rigidity of 5H and water contact angle is the least, but step is complicated,
The most anti-fog properties typically energy consumption is big, simply has the user of special high request suitable to performance.
Domestic patent CN102086348A discloses the preparation side of a kind of urethane cures acrylate anti-fog coating
Method, this coating is by hydrophilic acrylic resin, enclosed type polyethers isocyanate curing agent and catalyst dibutyltin dilaurylate
Composition.This coating hardness is more than 2H, and anti-wear performance is good, but it is general to continue anti-fog performance, and solidification process requires time for longer, and needs
Stage curing (50～120 DEG C), technique is complex.
For overcoming tradition anti-fog coating on the market to continue anti-fog performance and the contradiction of anti-wear performance, the open a kind of light of the present invention
The hydrophilic antifogging coating of hot dual cure.This coating first passes through heat cure, uses photocuring afterwards, the coating after solidification, parent
Aqueous is splendid and continues anti-fog performance remarkably, will not lose anti-wear performance simultaneously, therefore overcome the one of anti-fog coating on the market
A little drawbacks, are especially suitable for doing vehicle window, bathroom mirror etc. and have the field of antifog requirement.

Performance detects
Respectively to embodiment 1～5 and the coating for preparing of comparative example 1～8 carry out performance detection, measure the attachment of coating
Power, pencil hardness, wearability, initial stage water contact angle and sustained water contact angle performance.
The method of specific performance detection project and correspondence is as follows:
One, adhesive force
Use hundred lattice methods, with 3M Pressure sensitive adhesive tape, specimen page adhesive force is tested.
Appraisal procedure: 5B-scribing edge is smooth, line edge and intersection all without peeling paint；

Three, anti-wear performance
Using 0000# steel wool, 300g power, one is designated as once back and forth, and the number of times scratched occurs in recording surface.
Appraisal procedure: after the friction of certain number of times, observes whether coating has scratch, is resistant to when record is without scratch
Most Rubbing number.
Four, initial stage hydrophilic angle
Drip 4 μ L deionized waters at the specimen surface being cured, measure with contact angle tester in the range of 20～25 DEG C.
Five, hydrophilic angle is continued
The sample being cured is put into immersion 100h in deionized water, measures with contact angle measurement after drying.
By embodiment 1～5 and the test result of comparative example 1～8, including attachment, pencil hardness, wear-resisting, initial stage hydrophilic angle
The most hydrophilic angle, is summarized as follows table 3.
Table 5 embodiment and comparative example test result
As shown in Table 5, the hardness of embodiment is higher than comparative example, because embodiments of the invention use dual cure,
Further photocuring on the basis of heat cure, crosslink density is significantly larger than single curing mode, and performance is embodied in hardness and resistance to
On mill, the most single curing mode has lifting；Additionally, in comparative example, the hardness of photocuring system and wear-resisting micro-be better than heat cure
System, because its crosslink density is higher than heat cure；Comparative example 7 is consistent with embodiment 1 component with 8, but curing mode is different, right
Ratio 7 is only with heat cure, and comparative example 8 is only with photocuring, and therefore crosslink density is far away from dual cure, aspect of performance hardness
Wear-resisting do not reach requirement, and protracted hydrophilicity can not have embodiment 1 good yet.From the point of view of Comprehensive Correlation example and embodiment, parent in the early stage
Water aspect of performance, comparative example and embodiment difference are not too big, because the addition of surfactant, can reduce parent well
Water angle, plays the anti-fog effect of excellence, but at the most hydrophilic aspect, the hydrophilic angle comparative example to be less than of embodiment, because
Polymerisable surfactant has been received in agent structure by cross-linking reaction, adds the crosslink density of superelevation, cause even across
Water soaking also will not steep for a long time；And comparative example is soaked through long-time, hydrophilic angle can raise significantly, continues anti-fog properties
Can be poor, combination property does not reaches the effect of the present invention.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformation or amendment within the scope of the claims, this not shadow
Ring the flesh and blood of the present invention.
