Embodiment 1

[0021] A kind of screen printing method based on environmental protection, comprises the steps:

[0022] (1) Make screen printing plate

[0023] S1: Stretching the screen frame: Stretch the screen, first use the stretching glue to tightly bond the screen and the screen frame, then clean the screen with a degreasing agent, dry it, and then spray water on the obtained screen stretcher to adjust The tightness of the net tension makes the wire mesh tight on the net tension;

[0024] S2: Net stretch sizing: Use a scraper to evenly coat the photosensitive adhesive on the printing surface of the screen 4 times, and evenly coat the ink surface 2 times; after each gluing is completed and before the last gluing is completed , put the net stretched on a horizontal workbench at 0-5°C and let it stand for 3 minutes, then scrape off the air bubbles with a scraper, dry it in an oven at 35°C, and then apply the next photosensitive glue, and finally finish After the glue is applied once, it ...

Embodiment 2

[0030] The method of Example 1 is adopted, the difference is that: in the step S2, the photosensitive glue is evenly coated on the printing surface of the screen for 5 times, and evenly coated on the ink surface twice. The exposure time in step S3 was 6 minutes, the exposure time in step S3 was 5 minutes, and the sonication in step S4 was 20 minutes.

Embodiment 3

[0032] Using the method of Example 1, the difference is that: in the step S2, the photosensitive adhesive is evenly coated on the printing surface of the screen 8 times, and evenly coated on the ink surface 6 times. The exposure time in step S3 was 5 minutes, and the sonication in step S4 was 28 minutes.

Abstract

The invention provides an environment-protecting silk-screen printing method, and relates to the technical field of printing. The method comprises the steps that (1) a silk-screen printing plate is manufactured, specifically, S1, a screen is stretched around a screen frame, S2, glue is applied to the stretched screen, S3, exposure is carried out, and S4, the stretched screen is washed; (2) color matching and printing are carried out; and (3) printing ink is solidified. According to the method, the discharge amount of wastewater can be reduced, and a good printing effect can be obtained.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an environment-friendly screen printing method. Background technique [0002] Screen printing refers to using a screen as a plate base to make a screen printing plate with graphics through a photosensitive plate-making method. The principle of screen printing is to use the basic principle that the graphic part of the screen printing plate can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. When making screen printing plates, photosensitive glue needs to be coated on the screen. After photosensitive treatment in the dark room, the photosensitive glue on the opaque part of the screen needs to be washed away with clean water. The photosensitive adhesive is made of various chemical materials, and the composition of the cleaning solution is complex. After mixing with the wastewater in other processes, the resulting wastewater is difficult to t...
