Abstract

The invention discloses a printing ink of a woven bag, wherein the printing ink is prepared from the following raw materials in parts by weight: 30-40 parts of polyurethane-polyacrylate, 20-25 parts of ethanol, 10-15 parts of a pure acrylic emulsion, 8-10 parts of nano cellulose, 6-9 parts of a non-toxic pigment, 6-9 parts of water-borne wax, 1-3 parts of a defoaming agent, 1-3 parts of a macromolecular dispersant, and 0.5-1 part of nano Au25(SCH2CH3)18 clusters. The invention also discloses a processing technology of the woven bag, wherein the processing technology includes the steps: (1) preparing a resin solution; (2) preparing a coarse material color paste; (3) fully grinding the coarse material color paste to obtain a small-fineness colloidal liquid; (4) preparing a printing ink finished product; and (5) filtering. The polyurethane-polyacrylate non-toxic to human bodies is used as a graft material, ethanol is used as a solvent, the non-toxic and harmless pure acrylic emulsion andthe non-toxic pigment are added, and a printed product has no pungent smell and has high safety and environmental protection performance. The printing ink prepared by the printing ink formula and thepreparation technology has the advantages of uniform particle size, small fineness, excellent initial dry performance, and stable and excellent coloring strength and friction coefficient.

Description

technical field [0001] The invention belongs to the field of plastic woven bag printing, and in particular relates to a printing ink for woven bags and a processing technology thereof. Background technique [0002] The printing process of the woven bag is mainly to use the printing machine to print the composite roll cloth according to the user's layout mark, ink color, color registration, roll printing and rewinding; but the two-in-one composite bag has a smooth surface film and printing ink fastness It is difficult to solve. At present, the printing process in the industry uses oil-based inks. Oil-based inks are composed of pigments, linking materials, and solvents. Linking materials and organic solvents can dissolve many natural and synthetic resins. The content of VOC (volatile organic compounds) in the solvent is relatively high. many. After volatilization, it will cause air pollution, and it will be inhaled by the human body into the trachea, bronchi, lungs or transmi...
