Hyperfine double three-dimensional high molecular material integrated screen printing plate

Abstract

The invention discloses a hyperfine double three-dimensional high molecular material integrated screen printing plate which comprises a screen frame, a polyester screen, a steel wire gauze, high molecular film layers, high molecular pattern regions, photosensitive glue pattern regions and photosensitive glue lines. The high molecular pattern regions are separately arranged on the high molecular film layers and stretch to the bottom of the steel wire gauze, the photosensitive glue pattern regions fill the high molecular pattern regions, the photosensitive glue lines are arranged in the middle parts of the photosensitive glue pattern regions, and the high molecular pattern regions and the photosensitive glue lines are of hollowed structures. In this way, the high molecular materials in middle non-printed regions of the lines are super high in abrasive resistance and high in printing resistance, the service life of screen printing can be prolonged greatly, the deformation quantities of the silk screen and the patterns are reduced greatly, the printing quality can be improved greatly, high strength of high molecules is combined and high resolution of the photosensitive glue is also available, and meanwhile, new patterns can be re-manufactured after the screen printing plate is recovered and back-washed, so that the cost is saved greatly.

Description

technical field [0001] The invention relates to the production field of high-precision screen plates such as solar battery sheet screen printing screen plates and electronic components, in particular to a novel ultrafine double-stereo polymer material integrated screen plate. 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, among which solar energy research occupies an important position. As one of the core technologies of solar energy research, solar cells have also developed rapidly in recent years. Improving the conversion efficiency of solar cells is the main research object of solar cells at present. In addition to the selection and optimization of battery substrate materials and the improvement of cell manufacturing processes, etc. In addition to the requirements, t...

AI Technical Summary

Problems solved by technology

The screen plate produced by this method has certain limitations: the abrasion resistance of the emulsion is not good, and the friction with the substrate during printing is easy to wear and leak, which affects the surface printing quality and service life; the emulsion itself is greatly affected by the temperature and humidity of the external environment. , and the screen is easily deformed after being squeezed for a long time, resulting in a large overall deformation of the screen, which affects the overall printing quality
