Abstract
The invention relates to a screen printing plate applied to printing of a heating line of an automobile rear windshield glass and a manufacturing method of the screen printing plate. The screen printing plate comprises a screen frame and screen cloth, wherein the screen cloth is divided into a heating line region and a bus region; a heating line pattern layer is printed in the heating line region; a bus pattern layer is printed in the bus region; and a photosensitive glue layer is made on the bus pattern layer. Compared with the prior art, the screen printing plate has the advantages that the printing efficiency, the yield and the product quality are greatly improved; and the labor cost and the equipment cost generated during plate making and printing are reduced.
Description
Technical field
The present invention relates to a kind of half tone, particularly relate to a kind of half tone and preparation method thereof being applied to the printing of automotive rear windshields heater wire.
Background technology
At present along with the development of auto industry, more and more higher to the requirement (as aspects such as outward appearance, rear seat windscreen defrost performance) of vehicle glass, particularly the heat of rear seat windscreen heating defrosting completely by producing after the silver slurry line energising of serigraphy realizes, and auto vendor when design in early stage be avoid heater wire to arrange affecting driver's sight line heater wire design superfine (width only has 0.3mm, the length of line is more than 1300mm, and bus width also only has about 14mm).The half tone photoresists thickness that current process makes is identical, under similarity condition when heater wire region S2 temperature reaches requirement temperature, the region s1 temperature of tongue piece joint is welded higher than heater wire region in the bus be first energized, damage automotive trim because S1 place temperature is too high therefore can not Customer Standard be met, and by regulation voltage or when regulating the mode of conduction time or regulating resistance to reduce S1 place temperature, the temperature at S2 place also declines and also can not meet Customer Standard thereupon.In order to the problem that the temperature and bus S1 that control thermal treatment zone S2 are overheated, the way of widening bus was once adopted to accelerate the object of dispelling the heat, but this method causes the heating process of glass before tempering to become unstable because bus place silver slurry layer printing area is excessive, because silver slurry layer reflecting heat causes the temperature contrast of bus place glass temperature and other parts large, finally affect forming of glass so fail to use.And patent: by doing the printing area that hollowed printing design reduces silver slurry layer and then the glass heats tempering instability reduced because silver slurry layer reflecting heat causes on bus in the description of " 200580012852-has glass plate and the manufacture method thereof of conductive print ", but when this kind of method only can solve glass tempering reflection stove heat problem and can raise because of this area resistance value corresponding after silver slurry bus hollowed printing, and then the problem that after causing finished glass to be energized, bus temperature is too high can not solve, can not realize ensureing that the heating-up temperature in heater wire region reduces the object of bus-bar area temperature again, and current can only adopt two printing equipments repeat print for twice bus with increase bus S1 place silver slurry thickness thus reduce bus S1 place resistance value and quickening S1 place heat radiation, the temperature reaching S1 with S2 place is consistent, but adopt to produce in this way and seriously reduce the manufacturing cost that production efficiency also increases glass.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of can improve printing efficiency, yield rate and product quality greatly while, again reduce plate-making and print production in cost of labor, equipment cost be applied to automotive rear windshields heater wire print half tone.
Object of the present invention can be achieved through the following technical solutions: a kind of half tone being applied to the printing of automotive rear windshields heater wire, comprise screen frame, screen cloth, screen cloth is divided into heater wire region and bus-bar area, heater wire region is printed with heater wire patterned layer, bus-bar area is printed with bus patterned layer, it is characterized in that, described bus patterned layer is also printed with one deck photosensitive layer.
The thickness of described photosensitive layer is 10 ~ 20% of bus patterned layer thickness.
A kind of preparation method being applied to the half tone of automotive rear windshields heater wire printing, it is characterized in that, the method comprises the following steps: stretch tight on screen frame and establish screen cloth, make bus egative film and heater wire egative film respectively, then on screen cloth, use bus negative film making bus patterned layer, then in bus patterned layer, be coated with photosensitive layer, after oven dry, heater wire egative film is pasted onto on bus half tone, heater wire design producing is become a half tone having thickness difference with bus combination of patterns on half tone.
On described bus egative film, the region corresponding with heater wire region is coated into black, and region corresponding with bus-bar area on heater wire egative film is coated into black.
The making of described bus patterned layer is produced on oven dry on screen cloth by bus pattern by general screen printing method to obtain bus patterned layer; Be coated with one deck photoresists thereon again after bus patterned layer is formed, the thickness of this photosensitive layer is 10 ~ 20% of bus patterned layer thickness.
The thickness of described photosensitive layer is 5 μm.
The diagonal angle place of described bus half tone is provided with two loci: loci M1 and loci M2, heater wire egative film is provided with the loci R1 corresponding with described loci M1 and loci M2 and loci R2, when heater wire egative film is pasted onto on bus half tone, loci R1 is overlapped with loci M1, and loci R2 overlaps with loci M2.
This programme can make heater wire and bus two region photoresists produce thickness difference in same galley, to reach the equalized temperature of the rear rear seat windscreen bus of printing and heater wire two regions.Can meet the superfine and glass heats temperature requirement of rear seat windscreen heater wire need meet (germany volkswagen TL 82045C 200505 standard the 4.2nd, after+23 DEG C ± 5 DEG C (room temperature) heats 4 hours maximized surface temperature bus+50 DEG C+5 DEG C, the clause that heating region is+70 DEG C-7 DEG C) standard.
Compared with prior art, the inventive method can make the half tone with two or more different photoresists thickness, originally twice or the production model of repeatedly printing is made to change one-step print into, enhance productivity greatly, while yield rate, again reduce the repeat print cost of labor in producing and equipment cost.The two-part thickness difference in half tone bus-bar area and hot line region using this programme method to make can do any adjustment, so can meet the heating-up temperature requirement to rear seat windscreen of different client.
