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, relate in particular to a kind of half tone that is applied to the printing of automotive rear windshields heater wire and preparation method thereof.
Background technology
Present development along with auto industry, requirement (such as aspects such as outward appearance, rear seat windscreen defrost performance) to vehicle glass is more and more higher, particularly the heat realization that produces after the silver slurry line energising of serigraphy is leaned in rear seat windscreen heating defrosting fully, and auto vendor early stage when designing be avoid heater wire to arrange affect driver's sight line heater wire design superfine (width only has 0.3mm, the length of line surpasses 1300mm, and the bus width also only has about 14mm).The half tone photoresists thickness of at present process making is identical, under the similarity condition when heater wire zone S2 temperature reaches the requirement temperature, the regional s1 temperature of weldering tongue piece joint is higher than the heater wire zone in the bus of energising first, so can not satisfy Customer Standard because S1 place excess Temperature diminishes automotive trim, and by regulation voltage or regulate conduction time or the mode of regulating resistance when reducing S1 place temperature, the temperature at S2 place also thereupon decline also can not satisfy Customer Standard.For temperature and the overheated problem of bus S1 of controlling thermal treatment zone S2, the purpose that once adopted the way widen bus to accelerate to dispel 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 the silver slurry layer reflecting heat causes the temperature contrast of bus place glass temperature and other parts large, fail to use so finally affect forming of glass.And patent: unstable by doing the printing area that hollowed printing design reduces silver slurry layer at bus and then reducing the glass heats tempering that causes because of the silver slurry layer reflecting heat in the description of " 200580012852-has glass plate and the manufacture method thereof of conductive print ", but the problem of reflection stove heat when this kind method only can solve glass tempering and can raising because of corresponding this area resistance value behind the silver slurry bus hollowed printing, and then cause the problem of the rear bus excess Temperature of finished glass energising not solve, can not realize to guarantee that the heating-up temperature in heater wire zone reduces the purpose of bus regional temperature again, and thereby current two printing equipments bus of repeating print for twice that can only adopt reduces the resistance value at bus S1 place and the heat radiation at quickening S1 place with the silver slurry thickness that increases bus S1 place, it is consistent with the temperature at S2 place to reach S1, but adopts this mode to produce the serious manufacturing cost that production efficiency also increases glass that reduced.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of when can improve greatly printing efficiency, yield rate and product quality in order to overcome the defective that above-mentioned prior art exists, and has reduced again the cost of labor in plate-making and the print production, the half tone that is applied to the printing of automotive rear windshields heater wire of equipment cost.
Purpose of the present invention can be achieved through the following technical solutions: a kind of half tone that is applied to the printing of automotive rear windshields heater wire, comprise screen frame, screen cloth, screen cloth is divided into heater wire zone and bus zone, the heater wire zone is printed with the heater wire patterned layer, the bus zone is printed with the bus patterned layer, it is characterized in that, also is printed with one deck photosensitive layer on the described bus patterned layer.
The thickness of described photosensitive layer is 10～20% of bus patterned layer thickness.
A kind of preparation method that is applied to the half tone of automotive rear windshields heater wire printing, it is characterized in that, the method may further comprise the steps: stretch tight at screen frame and establish screen cloth, make respectively bus egative film and heater wire egative film, then use bus negative film making bus patterned layer at screen cloth, be coated with photosensitive layer in the bus patterned layer again, after the oven dry, the heater wire egative film is sticked on the bus half tone, the heater wire design producing is become a half tone that thickness difference is arranged on half tone and with the bus combination of patterns.
Zone corresponding with the heater wire zone on the described bus egative film is coated with into black, and zone corresponding with the bus zone on the heater wire egative film is coated with into black.
The making of described bus patterned layer is to be produced on to dry on the screen cloth by general screen printing method by the bus pattern to obtain the bus patterned layer; Be coated with one deck photoresists after the bus patterned layer forms thereon, the thickness of this photosensitive layer is 10～20% of bus patterned layer thickness again.
The thickness of described photosensitive layer is 5 μ m.
The place, diagonal angle of described bus half tone is provided with two loci: loci M1 and loci M2, the heater wire egative film is provided with the loci R1 corresponding with described loci M1 and loci M2 and loci R2, when sticking on the heater wire egative film on the bus half tone, loci R1 is overlapped with loci M1, and loci R2 overlaps with loci M2.
This programme can make heater wire and two regional photoresists of bus produce thickness difference in same galley, to reach the equalized temperature in the rear rear seat windscreen bus of printing and two zones of heater wire.Can satisfy the superfine and glass heats temperature requirement of rear seat windscreen heater wire need satisfy (germany volkswagen TL 82045C 200505 standards the 4.2nd ,+23 ℃ ± 5 ℃ (room temperature) heating maximized surface temperature bus after 4 hours+50 ℃+5 ℃, the clause that heating region+70 are ℃-7 ℃) standard.
Compared with prior art, the inventive method can be made the half tone with two or more different photoresists thickness, make the production model of twice of script or repeatedly printing change one-step print into, enhance productivity greatly, when yield rate, reduced again cost of labor and the equipment cost of repeating print in producing.The two-part thickness difference in half tone bus zone and hot line zone that uses this programme method to make can be done any adjustment, so can satisfy different clients' the heating-up temperature requirement to rear seat windscreen.
