Problems solved by technology

When the resin has poor compatibility due to differences in molecular weight or functional group structure, although it can be uniformly dispersed under the action of a solvent, during the curing and molding process, as the amount of solvent in the system decreases, different types of resins will show phase separation. material performance deterioration

Abstract

The invention relates to an aqueous alkyd acrylic resin printing ink and a preparation method thereof. According to the invention, high-molecular alkyd resin with main chain containing unsaturated double bond is synthesized through molecular design. Alkyd resin is subjected to free radical graft copolymerization with acrylic monomer. A reaction system is neutralized by using an amine compound, such that water-reducible alkyd acrylic resin is synthesized. Molecular chains of alkyd and acrylic resins are connected through chemical bond, such that the compatibility of the two resins is improved. In a material curing and shaping process, phase separation of the resin is avoided. Deionized water, a pigment, a filling material, an antifoaming agent, a dispersing agent, a siccative, and alkyd acrylic hybrid emulsion are uniformly dispersed, such that the aqueous alkyd acrylic resin printing ink is obtained.

Description

technical field [0001] The invention relates to polymer chemistry and polymer coating composition technology. Background technique [0002] Most of the polymers used in traditional coating inks are solvent-based, and the main varieties are: alkyd resin, acrylic resin, phenolic resin, epoxy resin, polyurethane resin, amino resin and their mutual modification. These resins will use a large amount of organic solvents in the application of late coating inks and in the construction process. These solvents will volatilize into the atmosphere during construction and material curing, which is harmful to the health of construction workers, pollutes the environment, and causes energy waste. With the increasing awareness of environmental protection in various countries around the world, the restrictions on the content of volatile organic compounds (VOC) in inks are becoming increasingly strict in environmental protection regulations, and the ink industry is developing towards low pol...
