Technical Field

The invention belongs to the technical field of screen printing plates for screen printing processes, and particularly relates to a screen printing plate for a screen printing process, which is long in service life.

Background

AMOLED is a novel display screen technology, and has the advantages of high contrast, wide color gamut, low power consumption, ultrathin design, foldability and the like. However, the organic light emitting material used in the method is easily corroded and deteriorated by water and oxygen, and the service life of the material is shortened, so that the organic light emitting material is particularly important as a packaging technology for isolating water and oxygen. Frit glue encapsulation is a mature, general encapsulation technique, and this technique needs to use the half tone, and the effect of half tone is: the screen printing plate (non-cover plate contact surface) is coated with Frit glue, the screen printing plate (cover plate contact surface) and the cover plate glass are kept at a certain gap, and then the Frit glue is printed on the cover plate glass through meshes on the screen printing plate by a scraper of a screen printing machine, so that Frit glue with a certain height and a specific pattern is formed on the surface of the cover plate glass. The structure of the screen is shown in the attached fig. 1 and fig. 2 in the specification.

Because the screen printing plate is stained with Frit glue when in use, in order to ensure the cleanliness of the screen printing plate in the next printing, the screen printing plate needs to be cleaned by using a cleaning agent after the screen printing plate is placed off the machine, and the cleaning agent is generally an organic solvent and has certain solubility. When the cleaning agent washs the half tone, can take place to thoughtlessly to glue organic cleaning agent infiltration that the residue was glued to the Frit and advance the corrosion of half tone edge and glue that the half tone used on the half tone on the market at present all can take place to dissolve after a period with the organic cleaning agent contact that thoughtlessly glues the residue on glue the primer and the inferior silver dragon, and then lead to outer yarn to take place the skew, half tone tension takes place great change, and then leads to the whole printing position precision of half tone to take place the skew, and half tone is scrapped. The organic cleaning agent mixed with the Frit gel residue permeates into the edge of the screen printing plate and is shown in attached figures 3 and 4 of the specification.

Disclosure of Invention

The present invention is directed to a screen printing plate with a long service life for screen printing process, so as to solve the problems mentioned in the background art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a long service life's half tone for screen printing process, includes the metal screen frame, the inboard bonding of metal screen frame has outer yarn, the perpendicular contained angle position department of outer yarn and metal screen frame is equipped with the protection glue, four sides about the outer yarn is last all to be equipped with adheres the primer, outer yarn surface a week is equipped with the compound department of connecting of interior outer yarn, the inboard that the compound department of connecting of interior outer yarn is equipped with interior yarn, the surface of interior yarn evenly is equipped with the mesh, the bottom surface of adhering the primer is equipped with inferior silver dragon sticky tape.

As the further optimization of the technical scheme, the adhesion primer and the sub-silver adhesive tape are connected in an adhesion mode through the protective adhesive, the protective adhesive is a Solvent resistant adhesive, the adhesion primer can be prevented from being corroded by the organic cleaning agent, and the organic cleaning agent does not react with metal and the adhesion primer.

As a further optimization of the technical scheme, the metal net frame is made of metal alloy and has the effects of deformation resistance and Solvent resistance, so that the durability of the metal net frame is ensured.

As a further optimization of the technical scheme, the inner screen is made of a high-precision stainless steel mesh, the service life of the screen printing plate is prolonged, the outer screen is a high-strength polyester mesh, and the high-strength polyester mesh has certain deformation tension and can ensure the stability and quality of a screen printing process.

As a further optimization of the technical scheme, the adhesive primer, the metal screen frame and the outer yarn are bonded into a whole, so that the stability and firmness of the screen printing plate in use are improved.

As a further optimization of the present technical solution, the inner and outer yarn surfaces on the screen (cover plate contact surface) side are coated with the photosensitive emulsion, and the photosensitive emulsion is subjected to processes such as exposure and development according to a specific pattern during the screen manufacturing process, thereby forming a mesh pattern region without the photosensitive emulsion.

The invention has the technical effects and advantages that: this long service life's half tone for screen printing process, through the setting of inferior silver dragon sticky tape, can play the effect of protection to outer yarn and interior yarn to the life of interior yarn and outer yarn is improved. Through the perpendicular contained angle position of yarn and metal mesh frame contact outside and adhere the primer and sub silver dragon position between the sticky tape respectively scribble the one deck protection and glue, and the protection is glued for hindering the design that Solvent glued, can keep apart the organic cleaner who thoughtlessly has the residue of Frit glue, and then avoids organic cleaner to glue the primer and produce the corruption to being the design of aluminum alloy material through the metal mesh frame, can making the screen frame satisfy anti deformation, anti effect that Solvent glued. The Solvent-resistant glue is selected according to the properties of the Frit glue and the cleaning agent, if the Frit glue is weak alkali and the organic cleaning agent is water-soluble, the Solvent-resistant glue can be weak alkali-resistant and water-insoluble glue, and the Solvent-resistant glue can ensure that the Solvent-resistant glue does not react with the metal screen frame and the adhesive primer, so that the organic cleaning resistance of the screen plate is improved, the utilization rate of the screen plate is improved, the service life of the screen plate is prolonged, and the operation cost in the production process is reduced.

According to the screen printing plate, the layer of Solvent resistant glue is added on the basis of the original structure in the prior art as the protective glue, so that when the lower machine is cleaned by the organic cleaning agent after screen printing, damage to the adhesive primer caused by the organic cleaning agent mixed with Frit glue residues can be effectively prevented, the problems of outer yarn deviation, tension change, printing position precision deviation and the like caused by damage to the adhesive primer are prevented, and the service life of the screen printing plate is further prolonged.
