Problems solved by technology

This is an environmentally friendly emerging industry strongly advocated by the country. However, in order to ensure the printing speed and drying speed of the existing water-based inks during the printing process, alcohols such as alcohol are added as quick-drying aids. Often between 10 and 30, these lower alcohols are volatilized during the printing process, and still cannot be truly environmentally friendly

Abstract

The invention discloses water-based UV printing ink used for gravure printing and belongs to the field of printing materials. The water-based UV printing ink used for gravure printing is prepared from the following raw materials in parts by weight: 30-60 parts of waterborne polyurethane resin, 3-5 parts of a photoinitiator, 10-30 parts of pigment, 5-20 parts of filler, 0.05-0.5 part of a defoaming agent, 0.2-3.0 part of a wetting dispersant and 5-30 parts of water. The invention also provides a production technology of the water-based UV printing ink used for gravure printing. The water-based UV printing ink is non-inflammable and unexplosive and does not belong to dangerous chemicals, so that the security in printing, transportation and storage is enhanced; meanwhile, the water-based UV printing ink is not added with a quick-drying auxiliary or ethyl alcohol, zero release is realized, and the printing effect of the water-based UV printing ink can be equivalent to that of alcohol soluble printing ink and solvent type printing ink. The water-based UV printing ink has good adhesion and strong water resistance after being printed, so that the water-based UV printing ink is especially applicable to packaging printing materials for food, drink and medicines.

Description

technical field [0001] The invention belongs to the field of printing materials, and in particular relates to a water-based UV ink for gravure printing and a production process thereof. Background technique [0002] my country's UV technology development started in the 1970s. Compared with Europe, America and Japan, it started late, but it developed rapidly. From the beginning of a single UV wood coating, to the current UV screen printing ink and UV solder resist ink that can be produced, A series of inks such as UV paper inks, UV glazing inks, etc., and now my country has become the third largest producer of UV inks after the United States and Japan. Among them, the production of photoinitiators has ranked first in the world. However, relatively speaking, there are many low-end products and few high-end products, and the problem of unbalanced quantity and quality exists. Existing UV inks and water-based inks are all environmentally friendly products, but both have shortcom...
