Multi-channel stealth pattern of the present invention is meant that the same area in the metal surface passes through two kinds of concavo-convex patterns of corrosion, and meeting is mutual alternative with the variation of viewing angle; Promptly under different observation angles, can only clearly see a kind of pattern, another kind of pattern then is invisible mode.
" different observation angles " in this method refer to that object putting position angle is constant, and the sight line of human eye is constant, and light source direction changes; Refer to that also light source direction is constant, the sight line of human eye is constant, but the position angle that object is put changes; Refer to that also light source direction is constant, the object putting position is constant, but the sight line of human eye changes.Two kinds of patterns being told about in this method can be three kinds of patterns, but effect is good not as two kinds of pattern effects.Two kinds of patterns being told about can superpose, and also can not superpose.
The main method that forms multi-channel stealth pattern in the metal surface is the exposure etch, but multi-channel stealth pattern must design in computer software, and is carrier with the film, and multi-channel stealth pattern is transferred to the metal surface.
The light refraction principle and the preparation method of this method are produced concave-convex effect with other method in the metal surface, also can present the stealthy effect of coordination aniseikania, as laser engraving.
The employed material of this method mainly is a metal material, and employed method and technology are followed successively by Computer Plane Design, the stealthy optical information of computer photograph coordination aniseikania; film output; the metal decking polishing, metal surface exposure corrosion (pattern forms in the metal surface), metal surface protection.
After the multi-channel stealth pattern effect is made in the metal surface, can this be motherboard also with this method also, with frivolous materials such as paper that reflecting effect is arranged or Jin Bo, adopts the hot pressure method, also the stealthy effect of coordination aniseikania can be transferred to paper or Jin Boshang.
Embodiment
This method gives an actual example one: make " 50 " and the stealthy effect of the coordination aniseikania of " 50 "
The computer design that this example is said is all to make in coreldraw9.0 software.But can use identical preparation method and principle in other computer planar graph design software, to finish.
Manufacture craft flow process following (referring to accompanying drawing 1,2)
One, Computer Plane Design
This work is the known technology of Computer Plane Design, and any Computer Plane Design producer all can finish this work.
The main purpose of this work is to design the pattern that need form in the metal surface.
The pattern that designs is saved as different picture formats according to different design softwares, uses in order to next step action need.
Example: design a circle, in the circle numeral " 50 " is arranged, other has a Chinese character " 50 ", and two numerals have staggered place, (as shown in Figure 3)
Document stores " example 1.cdr " document.(attached electronic document) pattern actual size is diameter 12mm.
Two, computer photograph optical effect
The computer photograph optical effect mainly was divided into for two steps, and the one, the grating of design bottom, the 2nd, design two kinds of reflective information of different pattern optics.In this course, we have mainly found the straight line of corrosion different angles on metal, under different light irradiating angles, can form different reflecting effects, and form the symmetry variation with 180 degree corners.And the straight line of this different angles is done reasonably to arrange according to the pattern of front, and the pattern on the metal just can present different reflecting effects.(shown in Figure 12-17)
As Figure 12,13, if two kinds of patterns use the straight line of two kinds of different angles to show, these two kinds of patterns are subjected to the influence of direction of illumination under different angles, will present bright and dark effect.If the straight line or the shading of corrosion are also arranged on the bottom, dark pattern visually will be hidden in wherein, and is invisible, and bright pattern will be very clear, and that wherein Figure 12 is lines is reflective-bright, Figure 13 be lines not reflective-dark.
Use the lines of negative 15 degree of rotation as Figure 14-17: Figure 14, Figure 15 uses the lines of positive 15 degree of rotation, when main light source when left side irradiation is come, the lines that Figure 14 convexity gets up are reflective, make pattern shinny, and the lines that Figure 15 convexity gets up are not reflective, make pattern seem dark.When light source when the right irradiation is come, the lines that Figure 14 convexity gets up are not reflective, make the pattern obfuscation, and the lines that Figure 15 convexity gets up are reflective, make pattern seem bright.
If also corrode irregular lines or shading on the metal back layer, dark pattern visually will be hidden wherein, and is invisible, and bright pattern will be very clear, forms the multi-channel stealth pattern effect.
Concrete operation method is told about in conjunction with example.
2.1, in example design figure, in annulus, fill earlier chequered with black and white perpendicular line pattern.The wide 0.12mm of black lines wherein, white relief width 0.16mm.In this method example operation, black lines is all represented the corrosion next lines of projection later on, and white portion is all represented the sunk part of corrosion.(as shown in Figure 4)

2.2, black lines is divided into three parts, be respectively 0.03mm, 0.06mm, 0.03mm is wide, (as shown in Figure 5)
Related request: black lines is divided into three parts, and the width of three parts can be ordered certainly, but about general the requirement two equally wide, also can be equally divided into two.
2.3, the lines frame of pattern and the right 0.03mm of numeral " 50 " is intersected, Chinese character " 50 " is crossing with the lines of the 0.03mm on the left side, obtain lines " a 50 " graphical boxes and lines Chinese character " 50 " graphical boxes respectively.(shown in Fig. 6,7,8)
Annotate: the left side (Fig. 6) is the effect synthetic with circular vertical bar pattern, and the right (Fig. 7,8) is independent wire frame design sketch.
2.4, lines in the circular pattern " 50 " figure is filled to white, and insert black lines therein.The black line width is 0.084mm, and the space between the lines is 0.1mm, and lines all rotate positive 45 degree.Lines in the circular pattern " 50 " figure is filled to white, and inserts black lines therein.The black line width is 0.084mm, and the space between the lines is 0.1mm, and lines are negative 45 degree (black lines and figure have a certain degree) of rotation all.(shown in Fig. 9,10)
Related request: the angle of lines rotation is object of reference with the pattern angles.The angle of lines rotations can select 360 degree change in angle arbitrarily, be best a kind of of effect in the example.The lines of filling are between 0.2-0.05mm, and the gap is between 0.25-0.05mm.
The line thickness of talking about in the above-mentioned example can require to regulate according to reality, but it is thick generally should not to surpass 0.15mm, crosses thick naked eyes and just sees structural change clearly, loses stealthy effect.The carefullyyest generally should not surpass 0.05mm, be subjected to the restriction of production technology, be narrower than 0.05mm after, be unfavorable for quantizing to produce.
In other example of practical operation, otherwise interlaced pattern also can select the above lines angle of secondary to change.(as shown in figure 11)
Three, the output film
This is a known technology, mainly is that computer document is outputed on the film.
The output film will be selected the import film and import laser photo-typesetting ray machine for use.
The output of example film file requires: cloudy sheet, the medicine film is downward, 175 netting twines.
The film of output, the lines of black are that white is transparent in the file, white portion is a black medicine film in the file.
Four, metal surface polishing
The metal material of needs being made multi-channel stealth pattern flattens, and surface finish is beneficial to ink for screen printing.
In example, use the thick copper material of 0.36mm, be cut into the sheet material of the wide 200mm of long 305mm, use four brush Plate grinder nog plates.
Five, face exposure corrosion
The face exposure corrosion mainly is meant uses the ultraviolet photosensitive-ink to protect metal material; with ultraviolet photosensitive-ink silk-screen in the surface of metal material; photosensitive-ink through uv-exposure is insoluble to development liquid medicine; anti-etching; can protect metal material not to be corroded; and be not dissolved in development liquid medicine through the photosensitive-ink of uv-exposure, make metal material exposed and be corroded.Control photosensitive-ink be subjected to uv-exposure mainly to as if the film, when ultra violet lamp, the black medicine film of the film can stop ultraviolet light, and photosensitive-ink can not be solidified by ultra violet lamp.
This process mainly is to use exposure technology and etching process, goes out concave-convex effect in corrosion, forms multi-channel stealth pattern.
Relating to the prescription of chemical medicinal liquid in this process, is to improve with the process of the prescription in the public reference book, puts into practice verification through actual production.
5.1, the silk-screen photosensitive-ink
This process mainly is at metal material surface with the liquid photosensitive ink silk screen printing.
This process must be carried out in the half-light room that uses the gold-tinted pipe.(not having the irradiation of ultraviolet light and day ordinary light)
Here employed is liquid photosensitive circuit printing ink, and printing ink is general, and existing electronic circuit board manufacturer all uses, and is also available on the market.We have added anti-plain boiled water in printing ink, (how much deciding according to printing ink concentration of anti-plain boiled water).
At metal material surface, full version printing is about to the whole silk-screen good opinion of metal material surface gloss oil China ink with the photosensitive-ink silk-screen that mixes up.Employed half tone order number is at the 250-300 order.The ink coating that silk-screen is good is wanted evenly, and can not there be assorted point on the top layer.Employed in the example is 300 order half tones, manual silk-screen.
After silk-screen is good, use the baking oven have the air blast function that printing ink is dried, baking temperature is 90 degree Celsius, positive and negatively is no more than 5 degree Celsius, toasts 15 minutes.
5.2, uv-exposure
This process mainly is the photosensitive-ink exposure good to silk-screen, and the pattern-information on the film is transferred on the photosensitive-ink.Its cardinal principle is that photosensitive-ink is partly solidified through behind the UV-irradiation, be insoluble to development liquid medicine (sodium carbonate liquor), and, be dissolved in development liquid medicine not through what solidify behind the UV-irradiation, thereby show the metal material below the photosensitive-ink, form exposed metal pattern.What be used for the block ultraviolet line is the black medicine film of the film.
This process must be carried out in the half-light room that uses the gold-tinted pipe.
Concrete operation method is: the film is attached to the metal material surface of printed photosensitive-ink, is adjacent to, be placed on the uviol lamp, the distance between metal material and the uviol lamp is 60 ~ 80cm.The unlatching ultra violet lamp is closed uviol lamp after the several seconds, the film is torn from the metal ink surface fall.
The length of ultra violet lamp time and the energy of the ultraviolet lamp tube relation of being inversely proportional to.But can not use the excessive ultraviolet lamp tube of power, generally can not be above 5000 watts.Different fluorescent tubes and exposure machine require differently to the time for exposure, and the light pipe specification that uses with reality serves as with reference to doing actual the adjusting.The exposure machine that uses in the example, 3000 watts of power of lamp tube, the time for exposure is 12 seconds.
5.3, develop
This process mainly is that the photosensitive-ink of solidifying of not exposing is split away off from the metal surface, shows exposed metal pattern.
This process must be carried out in the half-light room that uses the gold-tinted pipe.
Employed method is that the metal material through overexposure is soaked in the development liquid medicine, the photosensitive-ink that not exposure is solidified is come off from the metal surface, and rinse well with running water.
Here employed development liquid medicine is sodium carbonate liquor, and concrete prescription is that 5% sodium carbonate adds 95% water.
During development, development liquid medicine is heated to 35-40 degree Celsius, will soaks 1-2 minute through the metal material after the exposure-processed.After the immersion, metal material is taken out from development liquid medicine, metal material surface is rinsed well (intact the closing of part of black on the film displayed, i.e. black part on the film will show the true qualities of metal material fully on the metal material after the development) with running water.
Example uses developing machine to develop, and whole procedure is all finished in machine, but uses liquid medicine prescription and temperature requirement and manual development in full accord.
5.4, the corrosion
Metal material exposed part after this process will be developed corrodes dented 0.05mm-0.1mm.
Its principle mainly is with exposed metal partial corrosion with corrosion liquid medicine.
Corrosion liquid medicine prescription is (example, a copper): anhydrous ferric trichloride (powdery) 25%, water 74.5%, technical hydrochloric acid 0.5%.The liquid medicine Baume degrees for preparing is 25.
Metal material after developing is immersed in the corrosion liquid medicine, and does slightly swing.Soak time is 3-5 minute, decides on the number of times and the concrete corrosive effect of liquid medicine corroding metal material.
After corrosion is good, metal material is taken out from corrosive liquid, rinse well with running water.
Example uses the etching machine corrosion, and whole procedure is all finished in machine, but uses the liquid medicine prescription in full accord with manual corrosion, and the time will lack, 1-2 minute.
5.5, take off film
This process mainly is that the photosensitive-ink on the metal material after the corrosion is taken off from metal material.
Its principle mainly is with striping liquid medicine the photosensitive-ink on the metal material to be removed.
Striping liquid medicine prescription: NaOH 5% adds 95% water.
When taking off film, striping liquid medicine need be heated to 45-55 degree Celsius.Metal material is immersed in the striping liquid medicine 2-3 minute then.After treating that photosensitive-ink comes off, metal material is taken out from striping liquid medicine, rinse (photosensitive-ink can not be arranged) well, dry water then with running water.
It is to take off the film machine that example uses, and whole procedure is all finished in machine, and it is in full accord to use liquid medicine prescription and craft to take off film, but the time will be lacked 1-2 minute.
So far, multi-channel stealth pattern is presented in the metal surface fully.
Six, metal forming processing and metal surface protection
