Abstract

The invention provides low-halogen rotation UV (Ultraviolet) environment-friendly ink, which comprises the following raw material components in percentage by weight: 55-75 percent of mixed resin, 5-11 percent of a mixed ultraviolet initiator, 0.05-0.5 percent of a polymerization inhibitor, 1-2 percent of a dispersing agent, 16-45 percent of a pigment, 1-3 percent of an adhesion accelerating agent, 1-3 percent of an anti-scratch wear-resistant aid and 3-8 percent of a functional filler. The invention further provides a preparation method of the low-halogen cycle UV environment-friendly ink. The low-halogen cycle UV environment-friendly ink provided by the invention is cured rapidly, is in a bright color, has soft and uniform color and luster, contributes to greatly enhancing the alcohol wiping resistance and eraser wiping resistance, and is free from halogen and heavy metals; small molecular active monomers and solvents are not used, so that volatile organic compounds (VOCs) are avoided, the irritant odor of ink is reduced greatly, and the ink is environment-friendly; and meanwhile, the ink has high flowability, high printing adaptability and high adhesion, and can be used for printing on various substrates and rotary printers.

Description

technical field [0001] The invention relates to a UV environment-friendly ink and a preparation method thereof, in particular to an ultraviolet light curing low-halogen rotary ink and a preparation method thereof. Background technique [0002] UV curable rotary ink (referred to as UV rotary ink) is composed of UV oligomer resin, active monomer, ultraviolet photoinitiator, pigment, filler and other ink additives. There are unsaturated double bonds in the molecular structure of UV oligomer resin and UV active monomer. When the UV photoinitiator is irradiated by ultraviolet rays, many free radicals will be generated. These free radicals are very active and have strong energy, thus triggering UV oligomers and active monomers to undergo cross-linking reactions and curing to form films. In the UV rotary ink, the UV oligomer has a large proportion in the whole formula and is the main film-forming substance. Therefore, the nature of the oligomer determines the main performance of ...
