Problems solved by technology

It can be seen that these public schemes are improvements on the basis of the current solvent-based transfer coatings, and still do not get rid of the harmful solvent volatilization or residual influence.
[0007] In addition to the hazards of solvents, the coating and drying of the currently used aluminized transfer coatings are all ordinary heating and drying, which consumes a lot of energy and is not conducive to energy saving.

Abstract

The invention relates to ultra-violet curing aluminized transferring coating and a preparation method and an application of the coating. The coating is prepared from the following components (by weight percent) as raw materials: 25-50 of acrylic ester resin, 32-60 of acrylic ester monomers, 3-15 of photoinitiator, and 0.5-3 of assistant, wherein the acrylic ester monomers at least comprise amino acrylic ester accounting for more than 5% of the total weight of the coating. The coating does not contain solvent, can be dried and solidified by adopting ultraviolet light source irradiation, completely removes volatilization of harmful solvent in coating process, does not need heat energy in the solidifying and greatly reduces energy consumption. After being carried out on coating drying, the coating has a coating film with good flexibly, can be carried out on laser mould pressing, is good in adhesiveness with an aluminum layer, can be easy to peel from a base film, is good in transitivity, resists high temperature, has excellent after-tack in a height temperature and high humidity environment, can be carried out on recoating, is good in printability and can completely meet all technical indexes of aluminized transferring coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an ultraviolet curing aluminized transfer coating and a preparation method and application thereof. Background technique [0002] As a holographic aluminized transfer paper that has been widely used in the packaging of social consumer products such as tobacco, wine bags, tea and cosmetics, the performance of the laser aluminized transfer coating is one of the key factors to realize the manufacture of this holographic aluminized transfer paper one. Since the holographic effect is achieved by laser molding and aluminum plating on the dry coating, the performance of the coating directly affects the laser moldability, high temperature and high humidity resistance, and post-printing processing performance of the final packaging material. [0003] At present, the laser aluminized transfer coating used in the production of this holographic aluminized transfer paper is mainly based on ...
