Ink for thin-paper waterborne intaglio printing of furniture and preparation method of ink

Abstract

The invention relates to ink for thin-paper waterborne intaglio printing of furniture. The ink is prepared from the following components: 13 percent to 38 percent of waterborne acrylic resin emulsion,12 percent to 38 percent of ethanol, 7 percent to 25 percent of pure water, 1 percent to 6 percent of waterborne dispersant, 0.1 percent to 1.5 percent of waterborne de-foaming agent, 0.1 percent to0.8 percent of ammonia water, 2 percent to 18 percent of filling agent and 5 percent to 50 percent of pigment. The improved waterborne acrylic resin emulsion is used as a main connecting material andthe waterborne de-foaming agent, the waterborne dispersant, the filling agent and the pigment are added; after a mixture is ground, the ink has relatively good fineness and color developing performance; furthermore, the water and the edible ethanol are used as a diluting gent so that the cost of printing raw materials is reduced; the VOC (Volatile Organic Compounds) content of the prepared waterborne ink is extremely low and a working environment of ink producers and printing operators is improved; potential safety hazards are solved and emission and pollution problems of a furniture paper intaglio printing industry are solved.

Description

technical field [0001] The invention relates to the technical field of furniture tissue paper printing, in particular to an ink for water-based gravure printing of furniture tissue paper and a preparation method thereof. Background technique [0002] At present, the inks used in the gravure printing of furniture and thin paper on the market are mainly oily solvents, and their components include toluene, xylene, ethyl ester, butyl ester, and cyclohexanone. Printing with oily solvents has the following disadvantages: (1) During the printing process The volatilization of oily solvents will cause large odors and toxic gases in the workshop, which will affect the health of producers. At the same time, after the oily solvents are treated with activated carbon, the emission of VOCs still exceeds the standard, causing pollution to the surrounding environment; (2) Oily solvents are flammable and explosive liquids, which pose great safety hazards during production and use.
