Problems solved by technology

Although this ink has excellent printability, good post-press processing performance, and fast drying, but due to (1) the relative toxicity of toluene, the residual solvent value of printed matter is high; (2) the thermal stability of chlorinated polypropylene is poor , in the process of production and storage, it is easy to release chlorine to form hydrogen chloride, which makes the ink highly acidic and severely corrodes the printing plate roller; (3) benzene-soluble ink can destroy the ozone layer, and it will also It is harmful to the health and safety of workers, and the residue left in the packaged products will cause a certain degree of pollution to the food in the package under certain conditions

Abstract

The invention discloses a food package printing ink and a preparation method thereof. The food package printing ink is prepared from the following raw materials in parts by weight: an ester solvent, a hydrocarbon solvent, a high-polymer dispersing agent, an anionic surfactant, organic silicon modified polyether, epoxy resin, organic pigment, diethylene glycol, a preservative, an antirust agent, a defoaming agent and deionized water through mixing, grinding and filtering. The food package printing ink is simple in preparation, lower in cost, environment-friendly, nontoxic, stable in performance, antiseptic and antirust, low in atmospheric pollution, free of poisonous solvent residues and beneficial to safety production and environment protection.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a food packaging ink and a preparation method thereof. Background technique [0002] With the improvement of living standards, people put forward higher requirements for food packaging. As a printing material, ink must abide by the principle of no transfer when it is applied to food packaging. Conventional inks are not allowed for food packaging. The printing manufacturer must ensure that all solvents in the ink evaporate after printing, and the ink must be cured thoroughly and meet the corresponding standards of the application industry. [0003] In the current food plastic packaging printing, benzene-soluble chlorinated polypropylene ink is the most widely used. The manufacture and use technology of this type of ink is mature, and it is mainly used in the back printing of BOPP (biaxially oriented polypropylene) materials, and the gravure printing method is used. Alth...
