Problems solved by technology

Although my country's screen printing originated very early, the development of modern screen printing technology is slow. Compared with foreign advanced screen printing countries, my country's technical level still has a certain difference. There is discoloration phenomenon in many cases, and the wear resistance and durability cannot fully meet the requirements.

Abstract

The invention discloses a silk-screen printing ink. The silk-screen printing ink is prepared from the following raw materials in parts by weight: 35-50 parts of polyester resin, 10-15 parts of styrene-acrylic resin, 20-35 parts of butyl cellosolve, 10-25 parts of a pigment, 8-15 parts of a filler, 0.5-3 parts of a dispersant, 0.5-3 parts of a defoamer, 1-3 parts of 2,4-dihydroxy benzophenone and 0.5-2 parts of castor oil. A preparation process of the silk-screen printing ink comprises the following steps: preparation of a resin solution, dispersion, grinding, filtering, packaging and the like.According to the silk-screen printing ink, as polyester resin and styrene-acrylic resin are taken as vehicles, no toxin, harm or VOC pollution is caused; the silk-screen printing ink has favorable adhesiveness on such printing stocks as a PVC panel and a thin film panel, is definite in image and text and free from after-tacking and dampness, cannot be dyed after being scoured, and particularly, has favorable printing fluidity and glossiness under high-temperature and high-humidity, or low-temperature and low-humidity environmental conditions; and the preparation process of the silk-screen printing ink is simple to process and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a screen printing ink and a preparation process thereof. Background technique [0002] With social progress and economic development, electronic and electrical products are widely used, product development is changing with each passing day, and operating systems are becoming more and more intelligent. Among them, especially with the improvement of the production process of membrane switches, electronic panels and buttons of electronic products, and the diversity of material surface hardening treatments, electronic products with higher performance have been produced. The above-mentioned high-performance electronic products all require high-end inks for decoration and protection. [0003] Screen printing is an ancient printing method. Like movable type printing, it is an invention in ancient my country. It originated from the clip printing process in the Qin and Han Dynast...
