Abstract

The invention discloses plant oil-based low-halogen environment-friendly ink and a preparation method thereof. The plant oil-based low-halogen environment-friendly ink is prepared from the following raw materials: pigment particles, polyethylene wax, a binder, soybean methyl oleate, a cobalt drying agent and a dispersing agent. The printing ink disclosed by the invention is refined from pure vegetable oil, is green and environment-friendly, is suitable for various offset printing machines, is quick to fix, quick to dry, high in gloss, stable in on-machine printing and good in wear resistance, and is a product which is excellent in printing performance and wide in application and is very in line with the environment-friendly requirements of packaging and green printing in various industries; the preparation method comprises the steps of dispersing and matching, rolling and grinding and filtering and packaging. The modified short-oil alkyd resin is prepared by a double-bond copolymerization method, and the modified alkyd resin has excellent self-drying property; the self-made modified short oil alkyd resin is put into the preparation process of the connecting material through a two-step method, and the prepared connecting material endows the ink with excellent flowing and printing capabilities, so that an ink film is high in gloss and resistant to friction.

Description

technical field [0001] The invention relates to an ink, in particular to a vegetable oil-based low-halogen environment-friendly ink and a preparation method thereof. Background technique [0002] Low-halogen offset printing ink, based on the advanced concept of green environmental protection, refined from pure vegetable oil, almost free of volatile components such as mineral oil, meets the standards of low-halogen, solvent-free, and aromatic hydrocarbons, and complies with European regulations on mineral oil (MOSH&MOAH) in inks Requirements for environmentally friendly inks. [0003] NON VOC inks are suitable for fast-drying products that have strict printing environment and emission requirements, but also have good printing performance. It has been nearly 10 years since NON VOC ink has been introduced to the market, but there are very few companies that have really mastered this technology. In the prior art, there are still many defects in the performance of the VOC-free ...
