One-step method for producing fast-drying plastic water-based ink acrylic resin binder

Abstract

The invention relates to a method for producing a quick-drying plastic aqueous printing ink acrylic resin binder by one step, which belongs to the technical field of acrylic resin synthesis production method. The method comprises the following steps: adding the follwong raw materials by weight part of 25-35 parts of acrylic acid monomer, 35-45 parts of styrene, 15-20 parts of butyl acrylate monomer, 5-10 parts of methacrylic acid, 5-10 parts of 3-mercaptopropionic acid and 1-3 parts of azodiisobutyronitrile in a reaction vessel, heating and controlling the temperature of 80-210 DEG C, stirring by grading, reacting and polymerizing to obtain acrylic resin; then adding 30-35 parts of polymerized acrylic resin, 60-65 parts of water and 2-5 parts of 2-amino-2-methyl-1-propanol in the reaction vessel, using the waste heat of the polymerized acrylic resin material, stirring, and emulsifying to obtain the acrylic resin binder. The method has the advantages of simple operation and saving energy, the product has the advantages of environmental protection and safety; the quick-drying plastic aqueous printing ink produced by the binder has the advantages of stable pH value, fast drying speed, high glossiness and environmental protection.

Description

technical field [0001] The invention relates to a synthetic production method of acrylic resin in the field of chemical industry, in particular to a method for producing fast-drying plastic water-based ink acrylic resin binder in one step and one step. Background technique [0002] In recent years, with the increase in the production of food, beverages, dairy products, cosmetics, detergents, beer, and condiments, the demand for printing and packaging of plastic and plastic composite materials is increasing. While the demand is increasing, the requirements for safety, environmental protection and stability are also getting higher and higher. However, at this stage, my country's plastic packaging printing is still dominated by solvent-based inks. Organic solvents containing volatile organic compounds in such inks generally account for 60% of the composition. Sexual organic substances not only pollute the environment, but also pose a hazard to the health of employees, and organ...
