Problems solved by technology

The main disadvantages of this process are: 1. Since the ink is printed after aluminum plating, it cannot be overprinted accurately, and the yield is not high. At the same time, acid or alkali will corrode the edge of the aluminum layer, making the fine lines or fine characters unable to be complete. 2. High concentrations of acid or lye not only pollute the environment, but also cause physical harm to production workers

Abstract

The invention discloses novel environment-friendly water-washable ink and a preparation method thereof. The ink is prepared from, by weight, 20%-60% of water-soluble resin, 10%-50% of acrylic copolymer resin emulsion, 10%-15% of titanium dioxide, 0.5%-1.5% of a dispersing agent, 0%-0.5% of an antifoaming agent, 0.1%-1.5% of a wetting agent, 0.1%-1% of silicon dioxide, 5%-18% of an alcohol-water mixed solvent and 0.1%-1% of an amination reagent. The water-soluble resin is one or two of water-soluble acrylic resin and waterborne polyurethane. The water-soluble resin, the acrylic copolymer resinemulsion and the amination reagent are mixed to be uniform, then the alcohol-water mixed solvent is added, then the dispersing agent and silicon dioxide are added, the mixture is continuously stirred,titanium dioxide is added, the materials are mixed to be uniform, then filtering is carried out, the wetting agent is added to filtrate, ammonium hydroxide is added for adjusting the pH value, and the novel environment-friendly water-washable ink is obtained. The environment-friendly water-washable ink is low in cost and excellent in printing performance and environment-friendly performance, andthe preparation method is simple and easy to use and popularize.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a novel environment-friendly washing ink and a preparation method thereof. Background technique [0002] Partially aluminized films are widely used in the flexible packaging industry for their visibility to the contents and special decorative effects. The traditional partial aluminum plating process is usually to coat a layer of oily ink on the area where the aluminum plating needs to be retained on the film after printing and vacuum aluminum plating to protect the aluminum plating layer in the area, and then use acid or alkali to treat the aluminum plating layer after drying. The aluminum-plated layer not coated with oil-based ink is melt-washed. Since the oil-based ink has the characteristics of acid and alkali resistance, the aluminum-plated layer coated with oil-based ink is retained, and the aluminum-plated layer not coated with oil-based ink is washed off. The ...
