High peeling environment-friendly type aqueous transfer coating and use thereof

Abstract

The invention relates to a high peeling-off environment-friendly waterborne transfer coating and an application thereof, wherein, the waterborne transfer coating takes the following components with the contents (parts by weight) as raw materials: 10 to 60 parts of waterborne resin; 0 to 10 parts of auxiliary agent; 0 to 10 parts of rheological control agent; 0 to 30 parts of cosolvent; 0 to 10 parts of pigment; 30 to 80 parts of deionized water; and 0 to 5 parts of pH value regulator. Compared with the prior art, the waterborne transfer coating has the following advantages of: (1) environmental protection and cost advantages: the waterborne transfer coating takes water as a main dispersion medium and has no organic solvent basically, very low content of volatile organic compounds (VOCs) and low production cost; (2) good printing adaptability: compared with a the solvent system, a waterborne system is different on the resin and the polarity from the solvent, thereby having good solvent resistance and being more applicable to the printing modes (such as gravure printing and screen printing) with higher requirements on the solvent resistance; and (3) the waterborne transfer coating can be directly used for replacing the existing solvent high peeling-off transfer coating by the pilot scale production confirmation.

Description

technical field [0001] The invention relates to a water-based transfer paint, in particular to a high-peeling environment-friendly water-based transfer paint and its application. Background technique [0002] Since the 1980s, the transfer aluminum plating process has set off a revolution in the packaging material industry by virtue of its advantages such as simpler process and lower cost. The tailor-made coating for transfer aluminum plating (hereinafter referred to as transfer coating) has been obtained A large number of promotional applications. The basic performance of the transfer coating is its peelability, that is, how easy it is to peel cleanly from the base film (PET polyester film, OPP stretched polypropylene film, etc.). The quality of peelability can generally be characterized by the peeling force between the transfer coating and the base film. A lot of practical experience shows that the transfer coating with a large peeling force is prone to the problem of unc...

Problems solved by technology

[0003] Existing high-stripping transfer coatings are solvent-based systems, which use a large amount of organic solvents. On the one hand, the high content of volatile organic compounds (VOCs) causes serious pollution to the production and use environment, and on the other hand, there is also the problem of high production costs.
