Example Embodiment

[0049] The present invention also provides a method for preparing any one of the above-mentioned ultraviolet light-curable film-coated adhesives, including the following steps:

[0050] Adding the urethane acrylate oligomer to the mixture of the first ultraviolet light curing monomer and the second ultraviolet light curing body, and stirring to obtain an intermediate;

[0051] The photoinitiator is heated and melted, and then the photoinitiator is added to the intermediate product, stirred and filtered to obtain the UV-curable film-coated adhesive.

[0052] It can be understood that the raw material ratio of the UV-curable film coating adhesive in the above preparation method is the same as that described above.

[0053] At the beginning of preparation, it is necessary to stir and mix the first UV-curable monomer and the second UV-curable monomer to prepare a mixed system of UV-curable monomers, where the stirring speed can be controlled to be 300-500r / min, for example 400r / min. Sub...

Abstract

The invention provides an ultraviolet-curable laminating adhesive and a preparation method thereof. The ultraviolet-curable laminating adhesive comprises, by mass, 20-35 parts of an polyurethane acrylate oligomer, 10-30 parts of a first ultraviolet curing monomer, 35-60 parts of a second ultraviolet curing monomer and 2-6 parts of a photoinitiator, wherein the glass transition temperature of the first ultraviolet curing monomer is 70-150 DEG C, and the glass transition temperature of the second ultraviolet curing monomer is -50-50 DEG C. The ultraviolet-curable laminating adhesive has the advantages of good transparency, strong caking property, high drying speed, and realization of high-quality high-light packaging at a low cost.

Description

technical field [0001] The invention relates to a coating adhesive, in particular to an ultraviolet light curing coating adhesive and a preparation method thereof, belonging to the technical field of printing. Background technique [0002] In recent years, with the improvement of living standards, there are more and more packaging types and specifications of products on supermarket shelves. Among them, the high-gloss series has a soft and quiet appearance, so it occupies a place in the packaging field and is the first choice for high-end product packaging. Focus on high-end mineral water labels, daily chemical product labels, gift packaging boxes, etc. in the market. [0003] At present, the high-gloss packaging method is mainly realized through the lamination process and the high-gloss varnish printing process. However, the gloss of the high-gloss varnish printing process is not as good as that of the lamination process, and the high-gloss varnish is not resistant to high-i...
