Abstract

The invention provides a preparation method of water soluble styrene-acrylic acid solid resin used for aluminium foil coating. The preparation method comprises the following steps of: firstly preparing an aliphatic carboxylic acid ethanol solution; secondly, mixing an aliphatic vinyl unsaturated monomer, an aliphatic unsaturated carboxylic acid monomer, a chain transfer agent, an initiator and an ester solvent to obtain a first pre-treatment solution; thirdly, heating and refluxing the ester solvent, then dropwise adding the first pre-treatment solution, and then adding the alphatic carboxylic acid ethanol solution, so as to obtain a base solution; fourthly, mixing an aromatic vinyl unsaturated monomer, an alphatic vinyl unsaturated monomer, a chain transfer agent, an initiator and an ester solvent to obtain a second pre-treatment solution; fifthly, heating and refluxing the base solution, then dropwise adding the second pre-treatment solution, so as to obtain a reaction solution; and sixthly, extracting, separating and drying, so that the water soluble styrene-acrylic acid solid resin used for the aluminium foil coating is obtained. By adopting the preparation method provided by the invention, pollution behaviours can be constrained, and production cost can be greatly reduced, so that the preparation method provided by the invention has a wide promotion value and high energy-saving efficiency.

Description

technical field [0001] The invention belongs to the technical field of preparation of styrene-acrylic resin materials, and in particular relates to a preparation method of water-soluble styrene-acrylic solid resin for aluminum foil paint. Background technique [0002] Cigarette packaging lining paper is basically divided into three categories: aluminum foil composite lining paper, transfer aluminized lining paper and direct aluminized lining paper. Up to now, the cigarette packaging lining papers on the market, especially the aluminum foil composite lining papers, all use solvent-based decorative and coloring protective coatings, such as coloring coatings using methyl ethyl ketone as a solvent, and coloring coatings using ethyl acetate as a solvent. Coatings, as well as coloring coatings using ethanol as a solvent, including partially water-soluble acrylic resin coatings developed by our company after technological innovation. When used in cigarette pack production enterpri...
