Problems solved by technology

[0003] Combined with the existing plate-making process, it needs to go through multiple processes such as netting, plate washing, coating, exposure, and imaging, and most of the processes are still done manually, especially the coating process, most of which use manual coating. The uniformity of the cloth cannot be precisely controlled, and the uniformity of the film thickness of the screen is a key parameter for customer printing. It directly impresses the quality of customer printing and the cost of paste, and at the same time, manual coating cannot achieve the film thickness required by customers at one time. Therefore, multi-project coating requires multiple dryings, wasting resources and man-hours, and drying multiple times at the same time. Due to the influence of the oven environment, tiny particles in the air will fall onto the screen photosensitive adhesive, resulting in customers' concerns. There are foreign objects in the product, and the energy loss of the hot air drying screen is relatively large
At the same time, the surface flatness of the P side of the hand-coated screen plate is poor, and it is necessary to increase the mirror surface process to improve it, which will further increase the defective rate of screen plate making and the production man-hours. At the same time, manual coating will waste a lot of emulsion and increase the cost of screen plate manufacturing.

Abstract

The invention discloses a film preparation process which is characterized by specifically comprising the following steps: 1, carrying out special treatment on a polyester film; 2, preparing an emulsion film by using an emulsifying device; 3, roll-coating the emulsion film obtained in the step 2 on the polyester film obtained in the step 1 by using a roll-coating machine; 4, drying the polyester film coated in the step 3; and 5, manufacturing the screen printing plate with the needed emulsion thickness in a machine film pasting mode. According to the invention, manual coating is changed into machine coating, the manufacturing time is greatly saved, the working efficiency of personnel is improved, the productivity is improved, a film is used for platemaking, multiple drying procedures are reduced to one drying procedure according to the principle, the platemaking yield is improved, raw material waste is reduced, raw material resources are saved, meanwhile, the heating procedures are reduced, heat energy emission is reduced, and environmental pollution is reduced.

Description

Technical field [0001] The invention relates to the technical field of film production, in particular to a film film preparation process. Background technique [0002] The existing stencil production process is generally to apply photosensitive glue on the surface of the steel wire mesh, or manual coating or machine coating, and then through the use of customer drawings of the film negative for UV exposure, and then develop the graphics It is finally produced in the process of inspection to achieve the purpose of printing and use by customers. [0003] Combining the existing plate making process requires multiple processes such as screen stretching, plate washing, coating, exposure, and visualization, and most of the processes are also manual operations, especially the coating process, most of which use manual coating and coating. The uniformity of the cloth cannot be accurately controlled, and the uniformity of the screen film thickness is a key parameter for customer printing, w...
