Problems solved by technology

[0008] However, the screen printing scratch-off inks used in the existing market all use solvent-based self-drying ink systems. The ink components contain a large amount of organic solvents such as xylene and 1500# solvent oil. , the air quality at the production site is poor, and it involves the production and use of dangerous chemicals. The risk factors in the production and use process are high, and it is increasingly unsuitable for people's requirements for environmental protection and their own health.

Abstract

A water-based letter scraping ink for silk screen printing is characterized by being prepared from, by mass, 30-60% of water-based strippable resin, 0.1-2% of a defoaming agent, 0.1-3% of a flatting agent, 2-5% of an antisticking agent, 0.5-3.5% of a dispersing agent, 2-6% of a thickening agent, 8-20% of a water-soluble thinning agent, 5-20% of titanium dioxide, 10-30% of water-based aluminum paste and 0.1-5% of water-based black paste. Compared with water-based flexographic letter scraping ink, the prepared water-based letter scraping ink for silk screen printing has the advantages that an ink layer is thick, soft in handfeel and strong in third dimension; compared with solvent-based letter scraping ink for silk screen printing, the prepared water-based letter scraping ink for silk screen printing has the advantages of being light in smell, environmentally friendly, free of combustion and explosion, high in safety coefficient in the production and use processes and the like; in the use environment of letter scraping ink with the same performance, the water-based letter scraping ink for silk screen printing can replace traditional oil-based letter scraping ink to be used in the technical field of anti-counterfeit printing of various lottery tickets and high-grade packages and other technical fields.

Description

technical field [0001] The patent of the present invention relates to the technical field of screen printing ink and its preparation field, in particular to a water-based scraping ink for screen printing and its preparation method. Background technique [0002] Screen printing ink, also known as screen printing ink, refers to a type of ink that is printed on the printing surface through the mesh of the printing plate. Screen printing, flexographic printing, offset printing, and gravure printing are the four most common printing methods in the world. Compared with other printing methods, screen printing has the following four advantages: [0003] ①It is not limited by the size and shape of the substrate, not only can be printed on a flat surface, but also can be printed on special shapes such as spherical surfaces and curved surfaces; [0004] ②The printing layout is soft and has a certain degree of elasticity, so it can not only print on soft substrates such as paper and c...
