Abstract

The invention discloses flexographic UV-LED printing ink and a preparation method thereof. The flexographic UV-LED printing ink is prepared from the following components, by weight: 30-40 parts of prepolymer A, 35-45 parts of monomer B, 4-6 parts of pigment, 5-7 parts of photoinitiator and 1-3 parts of assistant. The prepared flexographic UV-LED printing ink is small in viscosity, high in curing speed, high in color intensity and good in printability; the ink can be applied to the fields of printing packaging, labels and the like, and has small harm to the environment and human bodies.

Description

technical field [0001] The invention relates to the field of inks, in particular to a flexographic UV-LED ink and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and the improvement of people's material level. While people are enjoying a fast-paced life, environmental problems are also particularly prominent. "We need both gold and silver mountains, but also green water and green mountains" has become the goal pursued by people. Therefore, the promotion and application of environmentally friendly packaging and printing methods has become an inevitable development trend of printing and packaging. Because the flexo printing structure is simple and belongs to the green printing method, flexo printing has become synonymous with environmental protection in the printing industry. This feature of flexo printing makes it one of the most widely used printing methods in the printing industry. [0003] There are many types ...
