Abstract

The invention discloses a waterproof ink for packaging and printing and a preparation method thereof. The raw materials include: maleic resin, water-soluble acrylic resin, carboxymethyl cellulose, ethyl acetate, isopropanol, a stabilizer, a leveling agent, a defoamer, a dispersant, a waterproof agent, a slipping agent, pigments, xanthan gum, Arabic gum and fine pored silica gel. The specific stepsinclude: 1) mixing and heating maleic resin, water-soluble acrylic resin, carboxymethyl cellulose, ethyl acetate and isopropanol, and then performing stirring to obtain an emulsion; 2) heating the stabilizer, the leveling agent, the defoamer, the dispersant, the waterproof agent, the slipping agent and the pigments, then conducting ultrasonic vibration to obtain an auxiliary material; and 3) mixing xanthan gum, Arabic gum and fine pored silica gel, then adding the mixture into the emulsion, then adding the auxiliary material, performing high-speed stirring, and then conducting grinding. The ink prepared by the method provided by the invention has the advantages of simple process, low cost, good waterproofness, firm adhesion, etc., and has broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of printing ink preparation, and in particular relates to a waterproof ink for packaging printing and a preparation method thereof. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. [0003] Ink is a substance used to form graphic information in the printing process, so ink plays a very important role in printing. It directly determines the tone, color, and clarity of the image on the printed matter. In printing, we need to understand the composition of ink and the classification of ink. The ink should have bright colors, good printing adaptability, and suitable drying speed. In addition, it should also have certain application indicators for resistance to s...
