Problems solved by technology

It retains the performance of solvent-based resins and is more environmentally friendly than solvent-based resins. However, because it contains a large amount of strong hydrophilic carboxyl groups, the coating hardness is low after the coating is dried and formed into a film, and the slipperiness, wear resistance and anti-sticking properties Poor, it is difficult to meet the requirements of paper ink, varnish and water-based wood coating

Abstract

The invention discloses a waterborne acrylic resin and the preparation method, which aims to provide a waterborne acrylic resin and the preparation method which can not only keep the performance of organic solvent type acrylic resins, but also have friendly environmental protection property. The invention comprises the following matters of mass portion: 1 to 2 of acrylic, 15 to 29 of methyl methacrylate, 18 to 22 of butyl acrylate, 3 to 7 of styrene, 3 to 7 of 2-hydroxyethyl methacrylate, 0.25 to 0.65 of mercaptoethanol, 0.3 to 0.7 of azobisisobutyronitrile, 3 to 5 of isopropanol, 15 to 20 of ethanol, 2.5 to 8.75 of monoethanolamine and 25 to 31.5 of water.

Description

technical field [0001] The invention relates to an acrylic resin for ink and a preparation method thereof, in particular to a water-soluble acrylic resin and a preparation method thereof. Background technique [0002] In the prior art, the resin used for the pearlescent linking material is oily nitro resin, but it contains a large amount of organic solvents, which will pollute the environment, cause great harm to the human body, and is not safe, so the development is environmentally friendly The water-soluble acrylic resin is an urgent task to solve the above problems. [0003] Chinese patent CN20051022901 discloses an acrylic resin for coatings with good environmental protection and its preparation method, which is characterized in that 40-80% wt of acrylic acid monomer and 20-60% wt of organic solvent, 0.1-10% wt of initiator free radical solution polymerization After removing the organic solvent, the water-soluble acrylic resin with a solid content of 20-60%wt is obtaine...
