Polymeric membrane screen printing plate with optimized S-face coated structure

Abstract

The invention discloses a polymeric membrane screen printing plate with an optimized S-face coated structure. The polymeric membrane screen printing plate comprises a screen frame, wherein the interior of the screen frame is of a concave surface structure; a polyester mesh layer is arranged on the concave surface structure, a steel wire mesh layer is arranged at the position, located in the concave surface structure, of the upper portion of the polyester mesh layer, a polymeric membrane layer is arranged on the steel wire mesh layer, and an emulsion layer is arranged on the polymeric membranelayer; and the boundary contour shape of the polyester mesh layer is consistent with the boundary contour shape of the steel wire mesh layer, a hot melt adhesive layer is arranged between the polyester mesh layer and the steel wire mesh layer, and the polyester mesh layer and the steel wire mesh layer are compounded together through hot melt adhesive. The polymeric membrane screen printing plate with the optimized S-face coated structure has the beneficial effects that through the emulsion layer, the problem that the printing height is insufficient is effectively solved, and the printing efficiency of the screen printing plate is improved; the S face is coated with emulsion, so that the abrasion resistance of the S face of the screen printing plate is improved, and the service life of thescreen printing plate is prolonged; in addition, the emulsion layer is additionally arranged, so that the abrasion degree of a printing scraping knife is reduced, the service cycle of the scraping knife is prolonged, and the production cost of customers is reduced.

Description

technical field [0001] The invention relates to the production field of high-precision screens such as solar cell screen printing screens, MLCCs, TPs, PCBs, and 5G antennas, in particular to a polymer film screen with an optimized S-surface coating structure. Background technique [0002] With the increasing demand for energy, energy issues have increasingly become a major issue restricting the development of the international society and economy, which prompts people to continue to explore new energy sources, of which solar energy research occupies an important position; solar cells are one of the core technologies of solar energy research , has also been developed rapidly in recent years. Improving the conversion efficiency of solar cells is the main research object of solar cells at present. Innovative printing methods can also improve the conversion efficiency of solar cells. In the printing process of solar cells, the use of printing screens has a great influence on th...

Problems solved by technology

[0006] 2. The adhesive layer of the polymer film is not evenly distributed into the mesh

[0007] 3. When the amount of glue on the polymer film itself is too much, it is easy to have the problem of glue overflow, which will also affect the printing of the client

[0008] 4. It is easy to have the problem of worn scraper
