Embodiment Construction

[0017] A preparation method for water-soluble transfer coating, comprising the steps of:

[0018] (1) material preparation

[0019] Weigh the following raw materials in parts by weight: 10 parts of water-based polyurethane emulsion, 20 parts of water-soluble polyacrylate resin, 5 parts of glycol ether, 1 part of water-based wax emulsion, 1 part of modified organosiloxane, 1 part of modified silicone 1 part, 1 part of polysiloxane, 15 parts of isopropanol, 80 parts of deionized water;

[0020] (2) Preparation of water-soluble polyacrylate resin solution

[0021] Mix deionized water and isopropanol, heat to 72°C, gradually add water-soluble polyacrylate resin and stir until completely dissolved to obtain a water-soluble polyacrylate resin solution, in which the mass of deionized water and isopropanol The ratio is 1-2:1;

[0022] (3) Preparation of aqueous polyurethane emulsion solution

[0023] Adding deionized water to the water-based polyurethane emulsion, the mass ratio o...

Abstract

The invention relates to coating and particularly relates to a preparation method for water-soluble transfer coating. The preparation method comprises the following steps: preparing materials; preparing a water-soluble polyacrylate resin solution; preparing a water-soluble polyurethane emulsion aqueous solution; adding the water-soluble polyacrylate resin solution and the water-soluble polyurethane emulsion aqueous solution into a mixing tank for mixing, heating to 70-75 DEG C, then, adding a coalescing agent, an adhesion promoter, a wetting agent, a de-foaming agent and a flatting agent to uniformly stir, and adding deionized water, thereby preparing water-soluble transfer coating. The preparation method disclosed by the invention takes water as a main dispersing medium, and is green and pollution-free; an organic solvent is not contained, so that a problem that the cost is remarkably increased as international oil price is high in the presence of the organic solvent is avoided; a product prepared by the method has characteristics of low requirements on an adhesive and good applicability; after being transferred, the product is good in applicability to printing ink.

Description

technical field [0001] The invention relates to coatings, in particular to a preparation method of water-soluble transfer coatings. Background technique [0002] In recent years, in response to the requirements of environmental protection and resource conservation, most of the gold and silver paperboards used in the paper packaging fields of tobacco, alcohol, food, and daily necessities have changed from the original composite method to the transfer method. In the existing transfer process, the environmental problems caused by the volatilization of organic solvents, the finished paper caused by solvent residues cannot meet the requirements of VOC standards for materials, and the application cost problems restrict the healthy development of the industry. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing a water-soluble transfer coating that does not contain organic solvents, is environmentally friendly, and has goo...
