Problems solved by technology

[0003] Aluminum foil or aluminized paper is an indispensable packaging material. Aluminum foil or aluminized paper can be used to package products of various shapes, and can also be processed into containers of various shapes. However, ordinary ink cannot be directly coated on aluminum foil. Adhesion is poor, color saturation is not high, need to be improved

Abstract

The invention relates to the technical field of new materials, in particular to water-based gravure prime coat ink, which is prepared from the following raw materials in percentage by mass: 60 to 90 percent of styrene-acrylic acid copolymer emulsion, 0 to 30 percent of pigment color paste, 10 to 20 percent of edible alcohol, 0.5 to 1 percent of polyethylene wax, 15 to 25 percent of water and 0.2 to 0.4 percent of defoaming agent. The primer ink is full in color and luster, high in transparency, good in adhesive force and good in printing adaptability; the printing ink can be prepared into base coats with various colors according to requirements, and can be suitable for printing of a high-speed gravure press, the adhesion fastness of a printed product after being discharged from the press reaches 95% or above, the printing effect is attractive and elegant, and the problem that part of printing ink is poor in adhesion on aluminized paper can be remarkably solved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a water-based gravure primer ink. Background technique [0002] Gravure ink is the abbreviation of gravure printing ink, which is suitable for all kinds of gravure printing. Like other printing inks, gravure inks are mainly composed of colored substances (pigments) and binders. Among them, the colored substances play a role in color development, and the images are displayed on the substrate by forming a contrast with the different colors of the substrate. Gravure inks are mostly volatile solvent-based inks, which are composed of pigments, solid resins, volatile solvents, fillers and additives. Only when the ingredients and proportions of each raw material are properly prepared can the printing suitability and performance of the ink be achieved. Only in this way can the printing ink and the printing plate, the printing machine and the printing material be well coordinated,...
