Abstract

An environmental-protective printing ink with methyl-carbonate and dimethyl sulfoxide as mixed solvent in proportion of 1:0.20-0.30 is harmless. The printing ink consists of mixed solvent 35-55 proportion, resin 15-40 proportion, latent solvent alcohol 1-15 proportion, rosin modified resin 10-20 proportion, alcohol soluble modified aldehyde ketone resin 5-10 proportion soluble alkyd resin 1-5 proportion and pigment 10-15 proportion. It has excellent adaptability and has no harm to human body.

Description

technical field [0001] The invention belongs to the technical field of printing ink, and in particular relates to a solvent-type environment-friendly ink. Background technique [0002] Printing ink is a paste-like colloid formed by uniformly dispersing and mixing materials such as colorants and linking materials. The binder of solvent-based ink is composed of solid resin and a large amount of volatile organic solvent. After the solid resin is dissolved in the solvent, the coloring material is evenly dispersed in the linking material. After the ink is printed on the substrate, the solvent evaporates quickly and the conjunctiva is dried. The organic solvents in existing inks have different degrees of pollution and damage to environmental sanitation and personnel health, and there are often residual harmful substances in the dried ink layer, which cannot meet the requirements of food packaging and cigarette label printing. Ensuring environmental sanitation has become a major ...
