Abstract

The invention discloses aqueous gravure printing matt gloss oil, and belongs to the field of ink, wherein the aqueous gravure printing matt gloss oil comprises, by weight, 30-40% of aqueous acrylic emulsion, 25-35% of an aqueous acrylic resin, 0.5-1.5% of an aqueous dispersing agent, 0.1-0.5% of an aqueous defoaming agent, 5-10% of matting powder, 15-20% of deionized water, 1-1.5% of an aqueous leveling wetting agent, 2-2.5% of aqueous wax emulsion and 0.5-1% of an aqueous smoothing aid. The preparation method comprises: preparing materials; dispersing: stirring and dispersing at a low speed,and then stirring and dispersing at a high speed for 15-30 min until the materials are completely and uniformly dispersed; grinding 2-3 times, wherein the fineness is controlled within 10 [mu]m; and carrying out high-speed dispersion after the grinding, adjusting the viscosity, and inspecting the indexes of hue, drying speed and adhesion fastness. According to the invention, the problems of high toxicity, strong odor, low adhesiveness and the like in the prior art are solved, and the requirements of gravure printing can be met.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to a water-based gravure matt varnish and a preparation method thereof. Background technique [0002] With the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed. Gravure printing has always been an important part of the printing process, forming four major printing process systems with offset printing, flexo printing, and silk printing. With the development of printing process and technological change, gravure printing has expanded from flat printing to curved three-dimensional printing, especially in decorative printing, which has a very huge development potential. The gravure printing process has more prominent advantages, such as bright printing patterns, rich layer reproducibility, strong printing resistance of printing plates, and a wide range of substrates suitable for printing. [0003] The volatil...
