Abstract
The invention discloses a sand carving processing method of a precision screen printing plate. The sand carving processing method comprises the following steps: placing a metallic screen mesh stretched by a stretching mesh into sand carving equipment, and adding sand carving particles in the sand carving equipment; ejecting the sand carving particles under pressure by the sand carving equipment, coarsening the surface of the metallic screen mesh, and ejecting for 30-300 seconds so as to obtain the precision screen printing plate through sand carving processing. Through the manner, according to the sand carving processing method of the precision screen printing plate provided by the invention, the surface of the metallic screen mesh can be coarsened, the adhesive force of the surface of the screen mesh is increased, good contact between the screen mesh and a photosensitive layer in the subsequent coating working procedure is ensured, uniformly and densely distributed frosted pits are formed in the surface of the screen mesh after the sand carving processing, the effect of mirror reflection for original metallic material cannot appear, and the phenomena of scattering and reflection conditions of light during plate burning process are reduced, so that the images are clear during the subsequent plate burning process, the definition and tangent performances of lines are good, and the transfer amount of printing oil ink is increased.
Description
Technical field
The present invention relates to the treatment technology of solar cell, touch-screen, the contour precision metallic class of microelectronics half tone, particularly relate to a kind of accurate half tone sand and carve processing method.
Background technology
In silk-screen half tone manufacturing process, because the woven wire surface is very smooth, the photosensitive layer dynamics bonding with it that is covered in the woven wire surface is limited.In printing process, repeatedly scraping of adhesive tape of printing can cause the half tone photosensitive layer to come off, and formation pin hole spillage etc. are bad, cause the screen painting life-span to be reduced.In addition, the metal surface of light can form too much scattering and reflex in the printing down link, and the meticulous lines resolution of making can be able to be affected, and the reproducibility of image is poor, affect the transfer of printing-ink, thereby can't meet increasingly accurate silk-screen half tone, made requirement.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of accurate half tone sand and carves processing method, and the method increases the adhesive force of silk screen, in the service life of having improved half tone, promotes printing down pattern resolution, thereby improves the permeability of printing-ink.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of accurate half tone sand to carve processing method, comprise that step is:
(1) woven wire that net stretches tight that will stretch tight is put into sand equipment at quarter, in described sand equipment at quarter, adds 200-1600 purpose sand to carve particle;
(2) described sand equipment at quarter ejects described sand particle at quarter under the pressure of 0.2-0.4MPa, and alligatoring is carried out in described woven wire surface, and injecting time is 30-300 second, obtains carving through sand the accurate half tone of processing.
In a preferred embodiment of the present invention, described woven wire is stainless steel cloth, stainless steel steel disc, electroforming net or alloy silk screen.
In a preferred embodiment of the present invention, described sand is carved particle and is of a size of 600 orders.
In a preferred embodiment of the present invention, it is one or more in carbon granules, plastic grain, diamond dust, glass particle, silica dioxide granule or alumina particle that described sand is carved particle.
In a preferred embodiment of the present invention, described processing method also comprises to be protected the not sandblast zone of described woven wire.
In a preferred embodiment of the present invention, the pressure that described sand is carved equipment is set to 0.3MPa, and described injecting time is 60 seconds.
In a preferred embodiment of the present invention, the described sand medium that equipment is sprayed quarter is air-flow or current.
The invention has the beneficial effects as follows: accurate half tone sand of the present invention is carved processing method, the method can make the surface coarsening of metal material silk screen, increase the adhesive force on silk screen surface, guarantee that in follow-up painting process, silk screen is better with contacting of photosensitive layer, the silk screen surface forms evenly densely covered frosted shape pit after sand is carved processing, the mirror-reflection effect that not there will be the virgin metal material, the generation of scattering of light and reflex in minimizing printing down link, in follow-up printing down operation, make image more clear, lines resolution, tangent line are better, have improved the transfer amount of printing-ink.
The specific embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Embodiment mono-:
The invention provides a kind of accurate half tone sand and carve processing method, comprise that step is:
1, the net that stretches tight: woven wire is tightened and is pasted on screen frame, form half tone, described metal material silk screen is applicable to the metal material of any braiding order number, any weaving manner, any section bar characteristic, is all metal material grenadines such as stainless steel cloth, stainless steel steel disc, electroforming net, alloy type silk screen;
?2, sand is carved and is processed:
(1) woven wire stretched tight is put into to sand equipment at quarter, added 1200 purpose diamond dust in described sand equipment at quarter, and the not sandblast of described half tone zone is blocked with fig leaf;
(2) pressure of described sand equipment at quarter is set to 0.35 MPa, ejects described diamond dust, and the woven wire surface of described half tone is sprayed, and injecting time is 60 seconds, obtains carving through sand the half tone of processing;
?3, degreasing: sand is carved to the half tone handle well and carry out ungrease treatment, remove the grease on clean woven wire surface and dirty;
4, coating: the photosensitive coated layer on clean half tone in degreasing, photosensitive layer is covered in the silk screen surface, it can be the photosensitive material of emulsion shape, it can be also the sheet sensitization film film of pre-coating, owing to through sand, carving and processing, the silk screen surface forms evenly densely covered frosted shape pit, has increased the adhesive force of silk screen and photosensitive layer, has promoted the service life of half tone;
5, printing down: after the coated abundant drying of photosensitive layer, utilize ultraviolet printer, the figure on PET film film is transferred on half tone; Owing to through sand, carving and processing, the silk screen surface forms evenly densely covered frosted shape pit, the mirror-reflection phenomenon that not there will be the virgin metal material, reduced the generation of scattering of light and reflex in the printing down link, the image of making is more clear, lines resolution, tangent line are better, thereby have improved the transfer amount of printing-ink, realize better printing performance;
6, develop: water shower half tone surface, photosensitive layer uncured in the printing down link is rinsed out, thereby form image layers, complete image and be transferred to the process of half tone from PET film film, obtain the better half tone of anti-wear performance and printing performance.
