Problems solved by technology

Commonly used printing inks are generally made of chlorinated polymers. In the process of production and use, strong aromatic solvents are needed to dissolve and adjust the viscosity of the ink, which is irritating, not environmentally friendly, and the drying speed of the ink is too slow. During the printing process, it is easy to cause smudges on the back, uneven printing, deinking, etc., which seriously affect the printing quality

Abstract

The invention discloses printing ink and a preparation method of the printing ink and belongs to the field of plastic product processing. The printing ink comprises the following raw materials in parts by weight: 25-35 parts of alkyd resin, 8-15 parts of epoxy resin, 7-13 parts of alcohol, 5-8 parts of triethanolamine, 3-5 parts of light calcium carbonate, 0.5-2 parts of bactericide, 1-4 parts of lavender perfume, 12-17 parts of pigment, 0-3 parts of defoaming agent, 1-4 parts of dispersant and 1-4 parts of surfactant. The printing ink is environmentally friendly and nontoxic, free from a pungent smell and stable in performance, and has good glossiness; the abrasive resistance and blocking resistance of the printing ink can be improved by addition of light calcium carbonate; a printing effect is permanent; a drying rate is high; and the printing ink does not fall off in a use process.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a printing ink and a preparation method thereof. Background technique [0002] With the development and progress of society, people pay more and more attention to the quality of life and life comfort, and the quality requirements for printed products are becoming more and more stringent. , should minimize its adverse effects on the surrounding environment and the human body. [0003] At present, more than 95% of the printing of domestic plastic flexible packaging is by gravure printing. Commonly used printing inks are generally made of chlorinated polymers. In the process of production and use, strong aromatic solvents are needed to dissolve and adjust the viscosity of the ink, which is irritating, not environmentally friendly, and the drying speed of the ink is too slow. During the printing process, it is easy to cause smudges on the back, uneven printing, deinking and...
