Description
Technical field
The utility model relates to the roller mould that has the pore of a plurality of trickle concaveconvex structures on a kind of surface of the aluminium base at hollow cylindrical, uses the surface of this roller mould manufacturing to have the parts of a plurality of projections and the article with anti-reflective function that use the antireflection film that is made up of these parts.
Background technology
Known have a following phenomenon: the surface has the parts of the trickle concaveconvex structure (for example moth ocular structure) that is made up of the trickle protuberance (projection etc.) of systematicness configuration and/or recess (pore etc.); Its refractive index changes in trickle concaveconvex structure continuously, manifests antireflection property thus.The surface has the parts of trickle concaveconvex structure in order to manifest good antireflection property, and protuberance or the interval between the recess adjacent in the trickle concaveconvex structure must be below the wavelength of visible light.In addition, the surface has the parts of trickle concaveconvex structure because lotus-effect also can manifest ultra water resistance.
As the method that forms trickle concaveconvex structure, for example propose to have following method etc.
(i) method that the mould that uses the surface to be formed with the inversion structures of trickle concaveconvex structure carries out injection molding or drawing;
(ii), the surface disposes active energy line curing resin composition between being formed with mould and the transparent base of inversion structures of trickle concaveconvex structure; Irradiation through active energy ray is solidified active energy line curing resin composition; Thereby form the top layer that transfer printing has the inversion structures of mould, the method for mould being peeled off from the top layer then with trickle concaveconvex structure;
The mold compresses of inversion structures that (iii) surface is formed with trickle concaveconvex structure is on active energy line curing resin composition; With the inversion structures transfer printing of mould on active energy line curing resin composition; From active energy line curing resin composition, mould is peeled off then; Irradiation through active energy ray is solidified active energy ray-curable resin compound, thereby forms the method on the top layer with trickle concaveconvex structure.
(i)～(iii) in the method, if consider the transfer printing property of trickle concaveconvex structure, the free degree of surface composition, then (ii) method is better.But method (ii) is particularly suited for using the situation of the mould of quantity-produced band shape or roller shape, is the excellent method of productivity ratio.As the excellent method of productivity ratio, roll-to-roll mode is a known technology.Adopt roll-to-roll mode, but the trickle concaveconvex structure of the submicron order of the micron-sized trickle concaveconvex structure of transfer printing prismatic lens that kind or that kind such as diffraction grid and moth ocular structure.In addition, adopt roll-to-roll mode, but the seamless trickle concaveconvex structure of transfer printing.
As the mould of roll-to-roll mode, can enumerate for example following mould.
(1) outer peripheral face is formed with the roller mould (patent documentation 1) of the lens manufacturing usefulness of lens section transfer graphic.
(2) be formed with the roller mould (patent documentation 2) of the hollow cylindrical of anodised aluminium at the outer peripheral face of the aluminium base of the hollow cylindrical of processing through extrusion molding with a plurality of pores.
(3) at the roller mould (patent documentation 3) that is formed with the hollow cylindrical of anodised aluminium through the outer peripheral face that forges, cuts the aluminium base of the hollow cylindrical of processing with a plurality of pores.
Have the applied purposes of a kind of antireflection film of the parts of trickle concaveconvex structure as the surface, can enumerate various displays.In various displays, the commercial television machine also has the tendency of maximization in recent years, and stock size has reached 32 inches.Along with the maximization of television set, hope that mould also is to grow size.Though the size of mould should suitably design according to the size of television set, axial length is that the above roller mould of 800mm possibly be essential.
But, under the situation of the roller mould of (3), exist to be difficult to utilize forge to obtain axial length for the aluminium base more than the 800mm and also be difficult to be processed into the problem of hollow cylindrical.So, be under the situation of the hollow cylindrical aluminium base more than the 800mm making axial length, the manufacturing of the extrusion molding as the roller mould of (2) is fit to.
As the method for extrusion molding, generally be to use and change wire drawing die (Japanese: extrusion molding Port one ト ホ one Le ダ イ ス).The metal of extruding leaves at port section, combines once more and forms weld part in chamber portion, is configured as hollow cylindrical thus.At this moment, owing to the composition and the extrusion condition of metal sealing wire is remained on the outer peripheral face sometimes.
Also studied in order not make the eye-catching technology of sealing wire method (patent documentation 4) that the for example known shape that pair mould arranged designs etc.In addition, the external diameter of the aluminium base of hollow cylindrical is more little, is difficult for staying sealing wire more.But if external diameter diminishes, periphery just shortens.Under the situation of the trickle concaveconvex structure (moth ocular structure etc.) of continuously transfer printing submicron order, owing to can't avoid the wearing and tearing of roller mould, therefore must periphery be done length, production efficiency is improved.But external diameter is big more, easy more residual sealing wire.
Through composition and the extrusion condition optimization that makes aluminium base, can obtain at first sight not have the aluminium base of the hollow cylindrical of sealing wire.But; When carrying out anodic oxidation in order to form anodised aluminium and to the outer peripheral face of aluminium base with a plurality of pores; It is obvious that sealing wire becomes; Perhaps, even on the roller mould, can not discern sealing wire, in transfer printing the also residual sometimes vestige that causes by sealing wire on the parts (antireflection film etc.) of trickle concaveconvex structure of roller mould.

So-called machined surface is the face that contacts with transparent base on the surface of outer peripheral face transfer printing at transparent base of roller mould the time, is formed on a part of of aluminium base outer peripheral face or whole.
(shape)
For aluminium base 10, require when making the roller mould sealing wire of outer peripheral face not eye-catching, and have in transfer printing on the parts of a plurality of pores of anodised aluminium and do not produce the vestige that weldering is caused by wiring.Making axial length L is under the situation of the aluminium base 10 more than the 800mm, though the easy residual vestige that is caused by sealing wire through aluminium base 10 is made specific shape, just can make sealing wire not eye-catching.That is, D outer diameter being made 280～550mm, wall thickness T, to make 20～50mm be important.
The axial length L of aluminium base 10 is more than the 800mm.If the axial length of aluminium base 10 is more than the 800mm, then finally can obtain seamless (non junction) and the parts (antireflection film etc.) large-area, that the surface has a plurality of projections.
The D outer diameter of aluminium base 10 is external diameters of machined surface.When for example having external diameter in the end of aluminium base 10 when being done little part (not being the part of machined surface), the external diameter of this part also can be less than 280mm.
If the D outer diameter of aluminium base 10 is more than the 280mm, then be made under the situation that axial length L is the hollow cylindrical more than the 800mm, can will suppress lessly because of the deflection that deadweight produces.In addition, make in the periphery of aluminium base 10 also long enough, with a few myriametre units under the situation of the parts (antireflection film etc.) that the surface has a plurality of projections, can suppress the wearing and tearing of roller mould.If the D outer diameter of aluminium base 10 is below the 550mm, then operability is also good, and can evenly form anodised aluminium whole of the periphery of aluminium base 10.In addition, be not prone to sealing wire.The D outer diameter of aluminium base 10 is 300～500mm preferably, and 350～450mm is better.
The wall thickness T of aluminium base 10 is external diameter and internal diameter poor of the roller mould of machined surface.When for example having external diameter and wall thickness in the end of aluminium base 10 when being done little part (not being the part of machined surface), the wall thickness of this part also can be less than 20mm.
If the wall thickness T of aluminium base 10 is more than the 20mm, then when making the parts (antireflection film etc.) that the surface has a plurality of projections and to the outer peripheral face of roller mould, cuts and under the situation that the roller mould is utilized again, also can guarantee enough mechanical strengths.If the wall thickness T of aluminium base 10 is below the 50mm, change then within reason is heavy, also can keep operability, and in addition, the deflection that produces because of deadweight also can be suppressed lessly.The wall thickness T of aluminium base 10 is 30～50mm preferably, and 30～40mm is better.If wall thickness T is also thinner than 30mm, the cooling after then melt extruding is accelerated, sometimes with regard to easy residual sealing wire.In addition, if wall thickness T is much also thicker than 50mm, then the composition at junction surface changes easily, when carrying out anodic oxidation, sometimes periphery with difference appears in appearance easily.
Through aluminium base 10 is made this shape; Even the outer peripheral face of aluminium base 10 produces anodic oxidation; The lines that caused by sealing wire are not prone to yet, and have on the final surface that obtains on the parts (antireflection film etc.) of a plurality of projections to avoid the residual vestige that is caused by sealing wire yet.
(composition)
The aluminium purity of aluminium base 10 is 94.5～99.5 quality % preferably.If aluminium purity is more than the 94.5 quality %, then the element beyond the aluminium tails off, just control anodic oxidation easily, and the anodised aluminium that will have a plurality of pores easily is formed on whole of machined surface.If aluminium purity is below the 99.5 quality %, then the intermetallic compound appropriateness exists, and can fully form coarse concaveconvex structure, and the parts (antireflection film etc.) that can have a plurality of projections to the surface of final acquisition are given anti-dazzle property.
The magnesium amount of aluminium base 10 is 0.1～3 quality % preferably.If the magnesium amount is 0.1～3 quality %,, also be difficult for producing sealing wire even then make aluminium base 10 through extrusion molding.
As the amount of inevitable microcomponent in the manufacturing that comprises in the aluminium base 10 (100 quality %), preferably, the silicon amount is below the 0.4 quality %, and the iron amount is below the 1.0 quality %, and the copper amount is below the 0.2 quality %.If it is too much to make the amount of going up inevitable microcomponent; Then produce the part to form pore because of anodic oxidation, produce the problem on the performances such as the reflectivity of the parts (antireflection film etc.) that the final surface that obtains has a plurality of projections is enough not low sometimes.
(manufacturing approach)
Manufacturing approach as aluminium base 10; Can enumerate the method that is configured as hollow cylindrical through melt extruding, melt extrude shaping and for example be to use the extrusion molding that can change wire drawing die, make aluminium sheet add thermal flexure and be welded into method cylindraceous etc. with friction stirring joining method.After the shaping, preferably wait the outer peripheral face mirror-polishing through grinding.As method, can enumerate mechanical lapping, polishing grinding, chemical grinding, electrochemical milling methods such as (electrolytic polishings etc.) with the outer peripheral face mirror-polishing.
(action effect)
Aluminium base for the utility model of above explanation; Because D outer diameter is 280～550mm; Wall thickness T is 20～50mm, therefore, although axial length L is more than the 800mm; Can obtain a kind of like this roller mould: the sealing wire of roller mould outer peripheral face is not eye-catching yet, and has in transfer printing on the parts of a plurality of pores of anodised aluminium and be difficult for producing the vestige that is brought by sealing wire.
< roller mould >
The roller mould of the utility model is that anodised aluminium with a plurality of pores is formed on the roller mould at least a portion (the preferably whole face of machined surface) of the aluminium base outer peripheral face of the utility model.
(shape)
The axial length of roller mould is more than the 800mm.If the axial length of roller mould is more than the 800mm, then can obtain seamless (non junction) and the parts (antireflection film etc.) large-area, that the surface has a plurality of projections.
The external diameter of roller mould is 280～550mm.If the external diameter of roller mould is more than the 280mm, then can suppress the deflection that produces because of deadweight less.In addition, make in the periphery of roller mould also long enough, with a few myriametre units under the situation of the parts (antireflection film etc.) that the surface has a plurality of projections, can suppress the wearing and tearing of roller mould.If the external diameter of roller mould is below the 550mm, operability is also good.In addition, sealing wire is not eye-catching.The external diameter of roller mould is 300～500mm preferably, and 350～450mm is better.
The wall thickness of roller mould is 20～50mm.If the wall thickness of roller mould is more than the 20mm, then when making the parts (antireflection film etc.) that the surface has a plurality of projections or to the outer peripheral face of roller mould, cuts and under the situation that the roller mould is utilized again, also can fully guarantee mechanical strength.If the wall thickness of roller mould is below the 50mm, then can too not become heavy, also can keep operability, and the deflection that produces because of deadweight also can be suppressed lessly.The wall thickness of roller mould is 30～50mm preferably, and 30～40mm is better.
(manufacturing approach)
The roller mould of the utility model is through giving the outer peripheral face of the aluminium base of the utility model anodic oxidation, forming the anodised aluminium with a plurality of pores and make.
Also in advance the surface of the aluminium base before anodic oxidation by concavo-convex, the intermetallic compound of crystallization grain boundary come off and etching etc. forms coarse concaveconvex structure.In this case, form anodised aluminium, become the surface and have the roller mould that constitutes by coarse concaveconvex structure and trickle concaveconvex structure with the trickle concaveconvex structure that constitutes by a plurality of pores on the surface of the aluminium base that comprises coarse concaveconvex structure.Also but alternate repetition carries out etching and anodic oxidation.Transfer printing has the parts of the Compound Punch structure of roller mould, has the anti-reflective function of having given anti-dazzle property.
As anodised method, preferably carry out the method for following operation successively.
The 1st oxide scale film forms operation (a);

Oxide scale film is removed operation (b);
The scale removal film forms anodised pore origination point (following also note is made operation (b)) on machined surface.
The 2nd oxide scale film forms operation (c);
The machined surface that in electrolyte, will be formed with the aluminium base of pore origination point with constant voltage is given anodic oxidation once more, on machined surface, forms oxide scale film with pore corresponding with the pore origination point (following also remember make operation (c)).
The aperture enlarges treatment process (d);
Make the enlarged-diameter (following also note is made operation (d)) of pore.

The machined surface that in electrolyte, will have an aluminium base of the oxide scale film that has enlarged pore diameter with constant voltage is given anodic oxidation (following also note is made operation (e)) once more.
Repeat operation (f);
As required, repeat the aperture and enlarge treatment process (d) and oxide scale film growth operation (e) (following also note is made operation (f)).
Employing has the method for operation (a)～(f); On the machined surface of the aluminium base behind the mirror-polishing, periodically form diameter from the pore of peristome to the diminishing taper of depth direction; Its result can obtain to be formed with on the surface roller mould of the anodised aluminium with the trickle concaveconvex structure that is made up of a plurality of pores.
In operation (a) before, also can carry out preliminary treatment that the oxide scale film of the machined surface of aluminium base is removed.As the method for scale removal film, can enumerate method that impregnated in chromic acid/phosphoric acid mixed liquor etc.
In addition,, the purposes of the material of roller die surface is arranged, also can not carry out the operation (a) and (b), and begin to carry out from operation (c) according to transfer printing though the queueing discipline property of pore descends slightly.
Below, specify each operation.
Operation (a):
Form in the operation (a) at the 1st oxide scale film, in electrolyte, give anodic oxidation with the machined surface of the aluminium base of constant voltage after with mirror-polishing, as shown in Figure 2, form oxide scale film 14 at the machined surface of aluminium base 10 with pore 12.
As electrolyte, can enumerate acidic electrolysis bath, alkaline electrolyte, acidic electrolysis bath is better.
As acidic electrolysis bath, can enumerate oxalic acid, sulfuric acid and their compound etc.
In the situation that oxalic acid is used as electrolyte, the concentration of oxalic acid is preferably below the 0.7M.If the concentration of oxalic acid surpasses 0.7M, then the current value during anodic oxidation sometimes is undue becomes big and makes the surperficial roughening of oxide scale film 14.
In addition, the voltage through with anodic oxidation the time is set as 30～60V, is formed with the roller mould with the anodised aluminium that is spaced apart the high systematicness pore about 100nm thereby can obtain the surface.The high or low tendency that all can the decline of regular property of this scope of voltage ratio during anodic oxidation, free at a distance from bigger than wavelength of visible light.
The temperature of electrolyte is preferably below 60 ℃, and is better below 45 ℃.If the temperature of electrolyte surpasses 60 ℃, the tendency of the phenomenon that is called what is called " burn " is then arranged, and pore 12 is destroyed, dissolve on the surface sometimes, the systematicness of pore 12 is upset.
Sulfuric acid is being used as under the situation of electrolyte, and the concentration of sulfuric acid is preferably below the 0.7M.If the concentration of sulfuric acid surpasses 0.7M, then the current value during anodic oxidation sometimes is undue becomes big and can not keep constant voltage.
In addition, the voltage through with anodic oxidation the time is set as 25～30V, is formed with the roller mould with the anodised aluminium that is spaced apart the high systematicness pore about 63nm thereby can obtain the surface.The high or low tendency that all can the decline of regular property of this scope of voltage ratio during anodic oxidation, free at a distance from bigger than wavelength of visible light.
The temperature of electrolyte is preferably below 30 ℃, and is better below 20 ℃.If the temperature of electrolyte surpasses 30 ℃, the tendency of the phenomenon that is called what is called " burn " is then arranged, and pore 12 is destroyed, dissolve on the surface sometimes, the systematicness of pore 12 is upset.
In operation (a), implemented for long periods anodic oxidation and oxide scale film 14 thickenings that form, though can improve the queueing discipline property of pore 12, the thickness of the oxide scale film 14 of this moment is 2.5～30 μ m preferably.Thickness is during less than 2.5 μ m, carrying out under the anodised situation not carrying out preliminary treatment ground, and coming off of intermetallic compound can not fully be carried out sometimes.Thickness is 30 μ m when above, and productivity ratio descends.
Operation (b):
In operation (a) afterwards; Through removing the oxide scale film 14 that forms by operation (a); Thereby as shown in Figure 2, (being called the corresponding periodic depression of barrier layer (Japanese: バ リ ア
)) is pore origination point 16 to form bottom with removed oxide scale film 14.
Temporary transient remove formed oxide scale film 14, form anodised pore origination point 16, thereby can improve the systematicness No. the 5th, beneficial field " Applied Physics " 2000 the 69th volumes (for example with reference to the 558th page) of the pore 12 of final formation.
As the method for scale removal film 14, can enumerate and utilize dissolved aluminum not and the method removed of the solution of dissolved oxygen aluminium selectively.As this solution, can enumerate for example chromic acid/phosphoric acid mixed liquor etc.
Though utilize the operation (a) and (b) can improve systematicness, occur remaining in the sealing wire of aluminium base 10 inside or departing from of the distinctive composition of metal bond portion occurring at outer peripheral face sometimes.Especially, because anodised voltage is high more, the growth of oxide scale film 14 is just accelerated, and therefore, because scale removal film 14, internal structure just occurs from the teeth outwards easily.In operation (a); More than with 50V, especially the voltage more than the 80V carries out under the anodised situation; Through oxidization time is set as below 10 minutes, especially below 3 minutes; Thereby can suppress the growth of oxide scale film 14, though in operation (b) scale removal film 14, above-mentioned unfavorable condition is not occurred from the teeth outwards.
Operation (c):
The aluminium base 10 that in electrolyte, will be formed with pore origination point 16 with constant voltage is given anodic oxidation once more, forms oxide scale film 14 once more.
In operation (c), as long as under the condition (concentration of electrolyte, electrolyte temperature and formation voltage etc.) identical, carry out anodic oxidation with operation (a).
Thus, as shown in Figure 2, can form oxide scale film 14, this oxide scale film 14 is formed with columned pore 12.In operation (c); It is long more to implement the anodised time; The pore 12 that is obtained is also dark more, but is for example making under the situation of optics with the roller mould of parts such as being used to produce antireflection film, in operation (c); As long as form the oxide scale film 14 about 0.01～0.5 μ m, needn't form the oxide scale film 14 of formed the sort of thickness in the operation (a).
Operation (d):
In operation (c) afterwards, make the aperture of formed pore 12 enlarged-diameter in the operation (c) enlarge processing, as shown in Figure 2, with the diameter hole enlargement of pore 12.
Enlarge the concrete grammar of handling as the aperture, can enumerate such method: be immersed in the solution that is dissolved with aluminium oxide, utilize etching to make the enlarged-diameter of formed pore 12 in the operation (c).As this solution, can enumerate for example phosphate aqueous solution about 5 quality % etc.The time of operation (d) is long more, and the diameter of pore 12 is just big more.
Operation (e):
As shown in Figure 2, in case carry out anodic oxidation once more, just further form bottom from cylindric pore 12 to the little cylindric pore 12 of the diameter that extends below.
Anodic oxidation is as long as under the condition identical with operation (a).The anodised time is long more, and the pore 12 that is obtained is dark more.
Operation (f):
As shown in Figure 2; Through the repetition operation (f) that operation (d) and operation (e) are carried out repetition; Can the shape of pore 12 be formed diameter from peristome to the diminishing taper of depth direction; Its result can obtain the roller mould 18 that the surface is formed with the oxide scale film 14 (anodised aluminium) with periodic a plurality of pore 12.At last, being preferably in operation (d) finishes.
Through the condition of suitable setting operation (d) and operation (e), for example anodised time and aperture enlarge the time of handling, thereby can form the pore of different shape.As long as suitable these conditions of setting such as purposes according to the parts of wanting to make by the roller mould.In addition, making under the situation of antireflection parts such as antireflection film by this roller mould, owing to can change the interval and the degree of depth of pore arbitrarily through so suitably imposing a condition, so also can design best variations in refractive index.
Specifically; If under identical condition, repeat operation (d) and operation (e); Then form the pore of conical shaped, suitably change through the processing time that makes operation (d) and operation (e), then can suitably form the pore that hangs upside down mitriform, the pore of pointed shape etc.
Because the number of repetition of operation (f) is many more, the pore of formed taper is level and smooth more, therefore, preferably carries out operation (d) and operation (e) and adds up to more than three times, and is better more than five times.In number of repetition is secondary when following, the tendency that exists the diameter noncontinuity of pore to reduce, if made antireflection parts such as antireflection film by this roller mould, its reflectivity reduces effect and might worsen.
The result that the roller mould of so processing is formed with many periodicity pores is that the surface has trickle concaveconvex structure.And; When the pore in this trickle concaveconvex structure is spaced apart below the wavelength of visible light is that 400nm is when following; A plurality of pores of transfer printing roller die surface and the trickle concaveconvex structure of the parts processed becomes so-called moth ocular structure manifest effective anti-reflective function.
Because in a single day pore just produces visible light greater than 400nm at interval at random, therefore, do not manifest sufficient anti-reflective function, be inappropriate for antireflection parts such as making antireflection film.
Pore is the distance from center to the center of the pore adjacent with this pore of pore at interval.
Be used to make under the situation of antireflection parts such as antireflection film at the roller mould, pore is at interval preferably below the wavelength of visible light, and the pore degree of depth is that 50nm is above better, 100nm is above better, and is good especially more than the 150nm, best more than the 180nm.
If more than the pore degree of depth 50nm, be that the reflectivity of transfer surface descends then by the surface of the parts of the formed optical applications of transfer printing of roller mould outer peripheral face.
The pore degree of depth is the distance from the entirely deep of pore peristome.
In addition, the depth-to-width ratio of pore (degree of depth/cycle) is 1.0～4.0 better, and 1.3～3.5 is better, and 1.8～3.5 is good especially, and 2.0～3 is best.If depth-to-width ratio is more than 1.0, then can form the low transfer surface of reflectivity, its incident angle dependency and wavelength dependency also fully diminish.If depth-to-width ratio is big, then the wavelength dependency of the reflectivity of transfer surface just diminishes, and spares the tendency that reduction is also arranged by the irregular colour that the crystallization grain boundary causes.Shape is than 2.0 when above, and this tendency is obvious.The shape ratio was greater than 4.0 o'clock, and the mechanical strength of transfer surface has the tendency of decline.
