Screen printing ink and manufacturing process thereof

Abstract

The invention discloses screen printing ink and an application process thereof. The screen printing ink consists of printing color ink and a curing agent, wherein the printing color ink is 100 parts by volume and the curing agent is 3-10 parts by volume; the curing agent consists of the following components by in parts by volume: 100 parts of acrylic baking paint, 40 parts of isophorone, 20 partsof cyclohexanone and 25 parts of butyl acetate; and the application process of the screen printing ink comprises the steps of configuration of the curing agent, configuration of the screen printing ink, screen printing, drying and curing, etc. The process is simple and the screen printing efficiency is high. The screen printing ink provided by the invention is added with a curing agent for improving adhesion and wear resistance, and the main composition of the curing agent is a mixture of acrylic baking paint, isophorone, cyclohexanone, butyl acetate and the like, and the acrylic baking painthas good adhesion, wear resistance and gloss retention, so that the adhesion and wear resistance of the whole screen printing ink are greatly improved, a printed pattern is very stable, cannot fall off, has strong wear resistance, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a screen printing ink for screen printing and an application process thereof. Background technique [0002] Screen printing is one of the more commonly used printing methods at present. Screen printing is composed of five elements: screen printing plate, scraper, ink, printing table and substrate. The basic principle of screen printing is 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 printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the movement. Part of the mesh is extruded onto the substrate to form a pattern, and then the prin...

Problems solved by technology

[0003] Screen printing has a wide range of applications and is suitable for different printing materials such as fabrics, plastics, metals, ceramics, glass, and electronic products. Most of the inks used for screen printing of electronic products such as membrane switches and control panels have insufficient adhesion Well, it makes the pattern after printing unstable, and the printing quality is low, which affects the quality of the product
