Description
Technical field
Patent of the present invention belongs to a kind of process for improving functional product quality, is that practice is returned to from practice
In the application technology gone.Implement patent of the present invention, can achieve the purpose that increase functional product case hardness, small technology solves
Big problem.
Background technology
One, increase the case hardness of functional product, there is actuality and urgency！
Currently, the antifog or self-cleaning function implemented on antifogging product and hydrophilic self-cleaning product, substantially uses hydrophilic
The coating of property is realized.
The difference of anti-fog coating and hydrophily self-cleaning coat is：The hydrone contact angle of anti-fog coating is between 0-14 degree, parent
For the hydrone contact angle of aqueous self-cleaning coat between 0-90 degree, contact angle is smaller, and hydrophilicity is better.Anti-fog coating and hydrophily
Self-cleaning coat can be manufactured using same coating, be made on transparent material and be referred to as anti-fog coating, hydrophily self-cleaning coat can
To be made on any base material of product design needs (transparent or opaque).Hydrophily self-cleaning coat not necessarily has antifog effect
Fruit.
Hydrophily is antifog or hydrophily self-cleaning coat, and there are one general character：Functional effect, that is, anti-fog effect or self-cleaning effect are got over
Good, the hardness on surface is lower.On the contrary, case hardness improves, functional effect instead can degradation.Hydrophilic coating at present
Case hardness only has HB or below levels mostly.In addition, since coating has hydrophilic characteristic, it is just easier absorption air
In hydrone, when environment be unfavorable for these hydrones volatilization when, hydrophilic coating surface can because adsorbed water molecule and
Slight ruckbildung is generated, hardness can further decrease, and wearability also becomes worse.
To this, we are to have an intimate knowledge：Optical lens are the important applied fields of anti-fog coating, to case hardness
It is required that higher.Our affiliate --- optical lens manufactory is strong to this feedback, the Anti-fog glasses piece that they process
Also therefore there is more serious return of goods phenomenon.
It can be said that these existing functional products, include the anti-fog coating of our popularizations, all cannot ideally meet day
The needs for often producing and living.
So increasing the case hardness of these functional products, effectively extend its service life, there is actuality and compels
Cutting property！
Two, experimental result, practical experience and documents and materials prove：The case hardness for increasing these functional products, has
Operability！
1, it is summarized by the experience of result and actual use to functional product test in several years, it has been found that：This
There are two types of types for the mechanism of action of a little functional products：Slow-release and surface lysotype, the functional product of slow-release and surface
The functional product of lysotype is compared, and the functional product of slow-release has more one " micro-structure system ", this " micro-structure system
System " will not be dissolved in water.
So the functional coating of slow-release is existing always, and stored by the micro-structure system of coating itself
With release function ingredient (functional components are the general designations of antifog ingredient, hydrophilic self-cleaning ingredient, hydrophobic self-cleaning ingredient, under
Together), only functional components can be reduced because of gradually discharging --- and the service life of coating and functional components is different；Lysotype
Functional coating can with functional components it is gradual dissolving and disappear simultaneously --- coating is identical with the service life of function, that is, does not have
There is the presence of " micro-structure system ".
We can conclude that as a result,：The functional coating surface of slow-release, even if coating one possesses again
The film layer of " micro-structure system " can also just play as long as having release access and outlet, help function ingredient slowly to discharge
Corresponding function, that is, antifog, self-cleaning.
2, we also recognize from the expert of optical lens there and consulting literatures data, and the anti-reflection of optical lens increases
Saturating functional coating, removes the hydrophobic layer of outermost densification, and coating has spy that is apparent, being also the known micro-structure of industry
Sign, this is the inevitable outcome that optical lens use electron beam evaporation.Such micro-structure film layer is coated on slow-release
In functional coating, there is feasibility and operability.
3, Chinese patent《A kind of multi-functional anti-fog coatings of patent No. CN201510181288.1 and preparation method thereof》In, have
One viewpoint " anti-fog coating can be capped, and seal coat can enable water transmission ", anti-fog effect is unaffected.Certainly, it covers
Cover material is a kind of coating, and coating is " being lifting, spraying, spin coating, blade coating, roller coating or manual smearing by way of coating "
Come what is prepared, so case hardness is exactly the hardness of seal coat.The seal coat of " can enable water transmission ", is containing " hollow
The sol solutions of ball nano-particle ", " there are many gap, hole, cracks for hollow silica ball layer, hydrone can be made to shuttle
Go ", " microstructure features " of this and the high rigidity coating using vacuum coating manufacture described in patent of the present invention play the same tune on different musical instruments
It is wonderful, it is only completely opposite to these " can permeable coatings " or the definition of " coating of micro-structure " mechanism of action：The present invention
They are defined as " the release access of functional components and outlet ", anti-fog coating is " release type ", the meeting of anti-fog coating surface
" absorption " hydrone rather than " sucking " hydrone；And patent《A kind of multi-functional anti-fog coating and preparation method thereof》It is them
It being defined as " entrance and entering path of hydrone ", anti-fog coating " will suck " hydrone rather than " absorption " hydrone, we
Subjective judgement：Anti-fog coating should be " lysotype " used in him.
4,《Vacuum》Magazine the 2nd phase of March in 2003《Electron beam evaporation is studied with the performance evaluation that magnetron sputtering is aluminized》One
There are one research conclusions in text：" the A1 atoms of electron beam evaporation encounter substrate, lose energy, and mobility very little quickly, therefore former
Son rearranges more difficult on the surface, that is, the place deposited is exactly the place positioned, causes the gap between atom larger, table
Surface roughness is very big ", this can be described as " there is gap between atom, the coating in these gaps and gas phase deposited particles composition,
Just there is the coating of the microstructure features of the invention stated ".This is that optical lens anti-reflection functional film layer possesses " micro- knot
The theoretical explanation of structure ".
To sum up, the numerous phenomenons and factor of these all this kind appearance are linked together, just can inevitably people be allowed to produce
Raw association：If using technique for vacuum coating, coating one laminated in the slow-release functional coating surface with microstructure features
What kind of one micro-structure coating of the high rigidity target manufacture of suitable thickness, as a result can be？Through overtesting --- ready-made anti-
It is tested after plating layer of silicon dioxide on mist spectacle lens, as a result, it has been found that：Anti- fog effect and hydrophilic sexual function are not sent out substantially
Changing, the case hardness of Anti-fog glasses piece, but as glass --- 5H！On this basis, we attempt with some other
Hydrophilic high rigidity target and hydrophobic high rigidity target do repetition experiment, and same conclusion is above the same.
The birth of patent of the present invention, it may be said that be that when the water comes, a channel is formed, and is forced out by the awkward situation in market and product sale
If --- it has no idea to increase the case hardness of Anti-fog glasses piece, our anti-fog coating can not just may continue under popularization
It goes！
Invention content
Look for method to work hard on the formula and raw material, condition of cure of functional coating, be conventional technology and
As a result method is often got half the result with twice the effort, of inadequate achievement.
The present invention looks for another way, and breakthrough is had found except the formula of coating, obtains pleasantly surprised discovery so that functionality applies
The case hardness of layer can reach ideal firmness level, for example can reach glass or the hardness of metal (is increased to from HB
5H), and the phenomenon that softening will not occur because of adsorbed water molecule again in the surface of functional coating, keep high rigidity, height resistance to
The quality of mill can maintain a long-term stability constant.
Specifically method is exactly：Functional coating as priming paint, using high hardness material as target, using vacuum coating skill
Art, in the overlay coating of high rigidity of one layer of its covering surface or more with microstructure features, in this way these functional products
Case hardness 5H (using glass as reference, similarly hereinafter) can be increased to from HB.Meanwhile the high rigidity of vacuum coating manufacture
The microstructure features that overlay coating itself has show to manufacture coating, vapor deposition between the target particle of substrate surface
There is gap, these gaps and the molecular network of target grain just become the release access of functions such as antifog, hydrophilic, hydrophobic and
Outlet, to not interfere with the hydrophilic antifogging effect or hydrophilic self-cleaning function or hydrophobic self-cleaning function of product itself.In addition, such as
Fruit target selection is proper, and transparent micro-structure surface coating can also possess certain anti-reflection effect, with several different refractivities
Target superposition manufacture micro-structure, transparent overlay coating, anti-reflection effect can be more preferable, this is for optical glasses
A qualitative leap may be implemented in the quality of the products such as piece, security lens！
The anti-fog coating that the process of patent of the present invention has been promoted in optical glasses on piece as applicant is shared
Technology recommends, and to increase the case hardness of Anti-fog glasses piece, becomes one from coming in practice again in practice
Application technology.
Specific technical solution
One, increase the method for the hydrophily anti-fog coating case hardness of antifogging product：
It is high hard with hydrophily high hardness material or hydrophobicity the hydrophily anti-fog coating on antifogging product surface as priming paint
Degree material is target (such as silica, zirconium dioxide, titanium dioxide, tantalum dioxide, tin indium oxide, stainless steel, magnesium fluoride, fluorine
SiClx, hydrophobic silica etc.), using vacuum coating technology, have micro-structure special in one layer of its covering surface or more
The case hardness of the high rigidity of sign, transparent overlay coating, such antifogging product can be increased to 5H or more from HB.
If target selection is proper, transparent micro-structure surface coating can also possess certain anti-reflection effect.With several
The transparent surface coating of target superposition one micro-structure of manufacture of different refractivity, anti-reflection effect can be more preferable！This is optics
The process for the manufacture anti-reflection functional film layer that spectacle lens generally use.Certainly, for manufacturing the anti-reflection of Anti-fog glasses piece
The target film thickness needs of anti-reflection function film layer, various different refractivities recalculate, and to take into account anti-fog effect simultaneously and anti-reflection increases
Saturating effect.
The antifogging product of hydrophily high rigidity target manufacture, hydrophilic performance can be more preferable, under water and high humidity
The environment such as environment, such as bathroom, chafing dish restaurant, kitchen, anti-fog effect can be better, and are used under cold environment, there is knot
The possibility of frost.
The antifogging product of hydrophobicity high rigidity target manufacture, the hydrone of adsorption can be fewer, and hydrone is plating
Layer surface residence time also can shorter be that volatile ratio is very fast, so being used under cold environment, the possibility of frosting
With regard to smaller, anti-fog function can be better.
This method be suitable for various optical mirror slips, camera lens, various form products, various lamps and lanterns, various glass, bathroom mirror,
Plastic sheets etc. all need the product of anti-fog function.
Two, increase the method for the hydrophilic coating case hardness of hydrophilic self-cleaning product
It is high hard with hydrophily high hardness material or hydrophobicity the hydrophilic coating of hydrophilic self-cleaning product surface as priming paint
Degree material be target (such as silica, zirconium dioxide, titanium dioxide, tantalum dioxide, tin indium oxide, stainless steel, magnesium fluoride,
Silicon fluoride, hydrophobic silica etc.), using vacuum coating technology, increasing by one layer or more on its surface has micro-structure
The case hardness of the high rigidity overlay coating of feature, such hydrophilic self-cleaning product can be increased to 5H or more from HB.
Using effect can be better under damp and hot environment for the self-cleaning product of hydrophily of hydrophily high rigidity target manufacture,
Such as bathroom mirror, Lid of glass pot etc..The self-cleaning product of hydrophily of hydrophobicity high rigidity target manufacture uses under cold environment
Effect can be better, for example, the northern area of China building glass.
This method, which is suitable for preparing the surfaces such as various metals, glass, has the product of hydrophily self-cleaning function.
Three, increase the method for the hydrophobic coating case hardness of hydrophobic self-cleaning product：
It is high with hydrophily high hardness material or hydrophobicity the hydrophobic coating of hydrophobic self-cleaning product surface as priming paint
Hardened material is target, using vacuum coating technology, increases by one layer or more the high rigidity with microstructure features on its surface
The case hardness of overlay coating, self-cleaning product hydrophobic in this way can be increased to 5H or more from HB.
The self-cleaning product of hydrophobicity of hydrophily high rigidity target manufacture, is applied to kitchen appliance and apparatus, finishing material etc.
It is relatively good.And it can be relatively good on the self-cleaning product of the hydrophobicity product under water of hydrophobicity high rigidity target manufacture, hull.
In conclusion in the technical solution of patent of the present invention, there are three key elements：1, anti-fog coating, hydrophily
The match selection of coating, hydrophobic coating；2, the match selection of high rigidity target；3, the microfabrication of target material surface coating with
It safeguards.Three complements each other, indispensable：
1, the match selection of anti-fog coating, hydrophilic coating, hydrophobic coating --- the choice of current this kind of coating
Or very little：
(1) coating will possess good adhesive force simultaneously with base material and target, this is the content of common-sense；
(2) mechanism of action of coating will select (rather than the surface lysotype) of slow-release.The area of slow-release and lysotype
Point method is --- sample is immersed in 10-30 minutes in 40 ° of warm water, and (period swings sample several times in water, more conducively sees
Examine and judge), moisture is dried, is observed under fluorescent light：It is exactly lysotype cock skin phenomenon occur, it is smooth, smooth as before
Exactly slow-release.If continuously after soaked one day, the sample of slow-release touches in water, and there is one layer of sliding thing on surface
Occur, sample is taken out dry at this time, surface has one layer of white precipitate, but coating and does not see there is dissolved destruction
Trace, completely there is.
Hydrophily self-cleaning coating belongs to the coating of lysotype mostly at present, and service life is shorter.By force after plated film, function
Property coating and target coating between adhesive force meet water make moist after can be deteriorated until lose.So the functionality of surface lysotype
Coating is not suitable for using patented technology of the present invention.
(3) coating layer thickness is the bigger the better：Influence of the 5um and 15um film thickness to product function is different certainly；
(4) time of the product of coating preparation resistance to bubble at room temperature, the longer the better：Resistance to bubble is 1 hour small with resistance to bubble 100
When without influencing anti-fog effect or hydrophilic self-cleaning function, corresponding product function service life is different certainly, this
It is self-evident.
The implementation of patent of the present invention is limited by the selection of these functional coatings to a greater extent, these are functional at present
Coating also face and be much difficult to the technical bottleneck broken through.This is also that I closes this Techno-sharing to part as applicant
The reason of office uses：The matching anti-fog coating that applicant promotes has exclusiveness！Because antifog or hydrophilic (dredge
Water) adhesive force of coating and base material and target can be the technical barrier of a very bad solution.Apply for a patent or carry out theory
Discussion is the one thing, is applicable in production, that is entirely just another pair of shoes！
2, the match selection of high rigidity target：To possess good adhesive force with functional coating；The target of high rigidity is wanted
Consistent or close with the cold and hot shrinkage ratio of base material, otherwise having causes coating under the adverse circumstances such as cold or sweltering heat using going out
The risk being now cracked.
3, the microfabrication of high rigidity target material surface coating and maintenance：This can be produced using technique for vacuum coating
The feature coating of kind of micro-structure, it may be said that vacuum coating is that manufacture high rigidity micro-structure coating is most convenient, most straightforward approach.
Although using coating made of the nano-particle containing hollow ball structure, the face coat of microstructure features can also be produced,
But can such face coat possess " high rigidity " simultaneously, there are prodigious uncertainties.
It safeguards that the method for the coating of micro-structure is just to maintain the cleaning of coating surface, is not covered by other film layers or by dirt
Otherwise pollution can cause the anti-fog function of product itself, self-cleaning function to be lost！
The advantageous effect of patent of the present invention is：
The first, the case hardness of functional product is increased to 5H or more (same with glass or metal phase) from HB：
So that the quality of functional product is produced qualitative leap, reference is done with glass, case hardness can improve 10 times
More than, the wear-resisting resistance to wiping properties on surface are more excellent, and the service life is longer；
The second, contribute to open up thinking, the selection range of the raw material of expanded functionality product.
Third can be effectively facilitated market capacity and industry size of the functional product including functional coating
Expand, make those want with dare not use again, with the numerous enterprises and industry that dare not also use on a large scale, can courageously use, city
Field capacity and industry size are expected to double！
Patent of the present invention is from practice, into practice, it is not intended in solve the skill that domestic and international decades had not captured
Art problem, and be implemented with using existing equipment and technique, construction technology is simple and practicable, and functional product is made more to make
With value and economic implications.
