Manufacturing method of metal alloy composite screen plate

Abstract

The invention discloses a manufacturing method of a metal alloy composite screen plate. The manufacturing method comprises the following specific steps of 1) carrying out net pulling compounding; 2) manufacturing an alloy sheet pattern outer contour; 3) preparing a film layer; 4) coating an adhesive layer; 5) coating a film; 6) drying; 7) laser; 8) cleaning; and 9) detecting and packaging. In thisway, according to the manufacturing method of the metal alloy composite screen plate, a metal alloy sheet is adopted to replace traditional mesh cloth, and the manufacturing method has low elongationrate, better dimensional stability, printing resistance, puncture resistance, double supports of the metal alloy sheet and the film layer are adopted, the service life of the bonding strength far beyond a silk-screen and the film layer can be improved by 30% or above, and under the action of a high-molecular adhesive, the adhesion force of the high-molecular composite layer is extremely high, theplate making yield is greatly improved, the production cost is saved, the printing is good, the line type is good, and the efficiency of a battery piece is obviously improved.

Problems solved by technology

The screen produced by this method has certain limitations: 1. The resolution of the photosensitive emulsion under the action of light is not easy to grasp, and the flatness of the edge of the line after exposure and development is not good, and it is easy to affect the printing quality of the line when used; 2. The adhesion between the emulsion and the steel mesh yarn is not good, and it is easy to cause the plate emulsion to fall off after exposure and development, which greatly affects the plate-making yield; 3. The abrasion resistance of the emulsion is not
