Problems solved by technology

[0003] At present, the domestic ink-residing direct-plating beer label coating is a solvent-based coating. Due to its strong alkali resistance, the aluminum layer is not easy to be washed off during the de-labeling process, and the solvent is generally a volatile organic compound, which damages the atmospheric environment and harms human health. health and safety hazard

Embodiment 1

[0032] The acrylic emulsion of this embodiment is prepared using the raw materials of the following components and contents:

[0033]

[0034]

[0035] The above-mentioned aqueous acrylic acid emulsion is prepared according to the following process steps:

[0036] (1) Adopt pre-emulsified semi-continuous seed emulsion polymerization method:

[0037] 1. After rinsing the pre-emulsification tank, turn on the stirring at 800rpm to stir and disperse part of the pre-emulsion liquid and deionized water component B evenly.

[0038] 2. Then add the monomer C component of the formula amount and stir quickly for pre-emulsification, and set aside. Then keep the rotation speed at 250rpm, take out 10g as a seed, and add the initiator D component.

[0039] 3. Add deionized water and the remaining emulsifier A component into the reaction kettle, stir and heat up to 80°C, add initiator E to the base material for initiation, keep it warm for 5 minutes, add 10g of seed emulsion and keep...

Abstract

The invention provides a water-based environment-friendly coating used for an ink-retention directly-plated beer label and a preparing method thereof. The water-based environment-friendly coating comprises a bottom coating component and a face coating component. The bottom coating component is prepared from acrylics monomers, functional monomers, an anionic emulsifier, a nonionic emulsifier, an initiator and deionized water. The water-based environment-friendly coating and the preparing method have the advantages that the water-based acrylic coating can be subjected to coating under the indoor temperature condition, and construction is convenient; the coating does not require any film forming assistant or any cosolvent; water-based acrylate emulsion serves as a main film forming substance, organic solvents are basically not contained, the content of VOCs is quite low, and smells are quite low; the coating is good in film forming performance, high in aluminizing brightness and excellent in ink retention and leveling effect.

Description

technical field [0001] The invention relates to a water-based environment-friendly coating for ink-residing direct-plating beer labels and a preparation method thereof, belonging to the technical field of water-based coatings. Background technique [0002] With the international market attaching great importance to the environment, the labeling and packaging industry has begun to increase the requirements for the performance of environmental protection labels in the domestic market. With the continuous increase of beer varieties and the expansion of the consumer market, beer packaging is also constantly refurbished. In the process, the wine bottle needs to be soaked in lye to take off the label. The label is soaked in lye along with the bottle body. The ink layer on the surface of the beer label can adhere to the backing paper and not fall off or fall into the lye tank. In order not to pollute the lye and Recycling requires that the ink on the label should not fade or more t...
