Description
The technical field is as follows:
the invention relates to the technical field of a yellow light processing process of a touch screen, in particular to a yellow light processing process of the touch screen and protective alkali-removing ink used in the processing process.
Background art:
the yellow light process is currently the most popular manufacturing process in the TP (touch panel) industry, and has been commonly used in the production process of touch panel manufacturers. The principle of the yellow light process is a photolithography technique, in which a main pattern on a photomask is first transferred onto a photosensitive material, light is irradiated onto the photosensitive material through the photomask, and then the irradiated portion of the photosensitive material is dissolved or retained by soaking in a solvent, so that the formed photoresist pattern is completely the same as or complementary to the photomask. Since the photolithography process is performed in a yellow light environment rather than the red light of a conventional darkroom, this part of the process is often referred to as "yellow light".
The current yellow light process mainly comprises the following steps: gluing, exposing, developing, drying, etching, stripping and detecting. In the yellow process, it is usually necessary to protect the bottom glass, including the pre-treated ITO, PI, etc., from the direct UV light during exposure, to block light, and to avoid the erosion of the photoresist ink. The conventional protection method is to apply a protective film for protection, and then to tear off the protective film together in the later film stripping process. However, the protection mode mostly adopts manual operation, and along with the increase of the size of the touch screen at present, the degree of automation operation is continuously improved, the protection measure of attaching the protection film cannot adapt to the existing production requirement, and meanwhile, for the large-size touch screen glass, the cost of the product can be greatly increased by the attaching film for protection. Therefore, the present inventors have made extensive research and development to solve the above problems and propose the following improved technical solutions.
The invention content is as follows:
the invention aims to overcome the defects of the prior art and provides a yellow light process of a touch screen and protective alkali-removing ink used in the process.
In order to solve the technical problems, the invention adopts the following technical scheme: the yellow light process of the touch screen sequentially comprises the following steps: the method comprises the steps of gluing, exposing, developing, drying, etching, stripping and detecting, wherein before the gluing process, black protective alkali-stripping ink is printed on the surface of the touch screen which is subjected to pretreatment.
Further, in the above technical scheme, the protected alkali ink comprises 20-40% of anhydride copolymer resin, 1-10% of black pigment, 20-30% of polyester resin, 1-5% of curing agent, 0.1-0.3% of defoaming agent, 0.5-2.0% of flatting agent, 0.7-3.0% of coupling agent and 10-30% of solvent.
Further, in the above technical scheme, before the glue coating process, black protective alkali de-inking is firstly silk-screened on the surface of the touch screen through a 280-mesh polyester net, and then curing is completed after 15-20 minutes at the temperature of 150-.
Further, in the above technical solution, the thickness of the black protective alkali-removed ink screen is 25 to 35 μm.
Further, in the above technical solution, the black protective alkali-removed ink is removed by a developing solution in a developing process.
In addition, in the alkali-protecting and degreasing ink used in the yellow light process of the touch screen, any one of the following acid anhydride copolymer resins is used: copolymer resin of maleic anhydride and epoxy acrylic acid, and phenolic aldehyde epoxy acrylic acid copolymer resin.
Furthermore, the black pigment is used in the alkali-protecting de-inking ink in the yellow light process of the touch screen, and any one of the following pigments is adopted: copper chromium black, glass black, carbon black.
Furthermore, the alkali-protecting and oil-removing ink is used in a yellow light process of a touch screen, and the curing agent adopts an isocyanate curing agent.
Furthermore, the solvent is used in the protective alkali-removed ink in the yellow light process of the touch screen, and any one of the following solvents is adopted: DBE solvent and isophorone solvent.
The technical scheme adopted by the invention is that black protective alkali de-inking is additionally printed before gluing to replace the previous protective film, and the treatment of the glass sheet, such as ITO, PI and the like, in the previous stage can be protected from being corroded by light resistance ink or UV light. During exposure, the alkali-stripping ink is protected to be black, so that substances on the bottom layer can be protected from being corroded by strong light, a shading effect is achieved, a buffer effect is achieved for a developing solution during development, bottom glass can be protected, and finally the alkali-stripping ink is stripped before detection, so that a detection result cannot be influenced.
In addition, the protective alkali-removing ink can be attached to the surface of the glass plate by adopting a silk-screen printing method, so that the protective alkali-removing ink can directly and fully utilize the existing machine, is suitable for various types of glass, and can reduce the cost and improve the efficiency.
Finally, the alkali deprotection printing ink can be removed along with the photoresist printing ink, so that the steps of sticking and tearing the film are reduced, and the production efficiency can be further improved.
The specific implementation mode is as follows:
the present invention is further illustrated by the following specific examples.
The existing yellow light manufacturing process of the touch screen sequentially comprises the following steps: gluing, exposing, developing, drying, etching, stripping and detecting. Before this, it is necessary to perform ITO (conductive glass) processing on the glass sheet, and to use a sputtered ITO film layer. Then, a yellow light process is performed. The glue coating is a coating photoresist which is a photosensitive chemical material. Then, the property of the photosensitive material in the photoresist is changed through exposure, and the exposed pattern is processed through a developing device so as to clearly show the pattern. And then drying, etching, stripping and finally detecting to finish the ITO yellow light graph processing. The invention adds a process before gluing. Specifically, before the gluing process, black protective alkali-stripping ink is printed on the surface of the touch screen which is subjected to the pretreatment.
Before the gluing process, black protective alkali de-inking is firstly silk-screened on the surface of the touch screen through a 280-mesh polyester net, and then curing is completed after 15-20 minutes in the environment of 150-.
