Abstract

The invention discloses a local UV adhesive, and relates to the technical field of printing. The local UV adhesive comprises, by weight, 60-75 parts of polypropylene, 6-9 parts of an adhesive, 25-30 parts of a photoinitiator, 5-10 parts of a surfactant, 2-7 parts of a leveling agent, and 20-30 parts of an antioxidant. The local UV adhesive is based on polypropylene, so the local UV adhesive has a low cost; the local UV adhesive is used on a carton, so the carton resists moisture, and the local UV adhesive does not shed when the carton meets water; the antioxidant is added in raw materials, so the gloss decreases caused by oxidation of gloss oil is prevented; and the photoinitiator is added in the raw materials, so the brightness and the transparency are high.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a partial UV glue. Background technique [0002] Partial UV varnish is a kind of surface finishing technology for printed matters. It is named for its selective glazing of printed graphics with UV varnish with high brightness, transparency and wear resistance. It is used to highlight the theme of the layout. At the same time, it also improves the surface decoration effect of printed products. Partial UV is mainly used in the post-press finishing of book covers and packaging products to achieve the purpose of making printed products even better. [0003] Chinese patent CN201110447946.9 discloses a varnish formula and its preparation process, including the following components in mass percentage: resin: 30-45%, vegetable oil: 20-30%, ink oil: 20-30%, waxes Auxiliary: 1-5%, desiccant: 1-5%; the preparation process of the varnish is as follows: put vegetable oil and resin into the ...
