Problems solved by technology

However, at present, the temperature resistance of a small number of water-based systems cannot reach the level of solvent-based coatings. In addition, some water-based transfer coatings have poor peeling performance, which is prone to the problem of unclear peeling, leaving scattered defects on the surface of the finished product. Affect product quality and production efficiency

Abstract

The invention discloses a water-based transfer coating for printing. The water-based transfer coating for printing is prepared from following components in parts by weight: 30-50 parts of water-basedresin, 5-10 parts of an ionic liquid, 2-6 parts of ceramic particles, 0.5-1.5 parts of a coalescing agent, 0.05-0.15 parts of a defoaming agent, 0.05-0.10 parts of a leveling agent and 10-15 parts ofdeionized water. According to the water-based transfer coating for printing, a ratio of water-based acrylic resin to water-based polyamide resin is limited, the water-based acrylic resin and the water-based polyamide resin are enabled to be cross-linked to constitute a good network structure, meanwhile, the water-based resin can be modified with the ionic liquid, a coating system can be more flexible by the aid of anions and cations in the ionic liquid, and the lubricating effect is realized, so that stripping quality of the coating is improved; in the presence of the ionic liquid, a macromolecular structure of the resin can be uniformly filled with the ceramic particles, and temperature resistance of the coating system is enhanced.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a water-based transfer coating for printing and a preparation method thereof. Background technique [0002] Vacuum aluminized transfer coating is an important part of transfer aluminized paper. When using it, the coating is first coated on the substrate such as PET / OPP film, and then transferred to the surface of the paper after vacuum aluminizing, and the PET / OPP is peeled off to form Transfer aluminized paper. Due to the mirror reflection effect of the aluminum layer, the transfer aluminized paper has a high-gloss metallic texture and good printability, and can be widely used in various high-end packaging. [0003] Most of the transfer coatings used in the market are solvent-based systems, which use a large amount of ester ketone solvents such as ethyl acetate, butyl acetate, butanone, and some even use toxic organic solvents such as toluene and xylene. The production and us...
