Abstract

The invention discloses a preparation method of high-temperature-resistant easily-stripped printing water emulsion type resin, and the preparation method comprises the following steps: step 1) preparing a water-based emulsion of a nonionic emulsifier and an anionic emulsifier; step 2) under a stirring condition, after introducing nitrogen, adding a low-temperature initiator into the water-based emulsion of the step 1), and slowly dropwise adding a high glass transition temperature monomer into the water-based emulsion at a constant speed within 4-7 hours; step 3) preparing a high glass transition temperature resin seed emulsion; and step 4) and using a pump for pumping the high glass transition temperature resin seed emulsion obtained in the step 3) into a pre-emulsified nano oxide dispersion liquid for reaction to obtain the high-temperature-resistant easily-stripped printing water-emulsion type resin.

Description

technical field [0001] The invention belongs to the technical field of resin materials, and in particular relates to a preparation method of high-temperature-resistant and easy-to-peel printing water-emulsion resin. Background technique [0002] The water-based transfer protective coating is to coat a layer of paint on the surface of the paper-plastic film. After leveling and drying, a thin and uniform transparent bright layer is formed on the surface of the paper-plastic film. This layer not only makes the surface of the paper bright and smooth, but also plays a role Moisture-proof, anti-fouling, wear-resistant and other functions. The most important thing is that the water-based transfer protective coating can solve the problems of poor heat resistance, difficult peeling, difficulty in thermal transfer printing and printing adaptability of paper-plastic coating materials. It is truly green packaging and is being rapidly promoted and applied to advertising, Book covers, la...
