Abstract

The invention discloses a UV special release coating for a PET or BOPP film and a preparation method thereof. The release coating is prepared from the following components in parts by weight: ultraviolet curing resin is prepared by mixing modified epoxy organic silicon acrylic resin and pure acrylic resin. Through polymerization reaction among the components, a coating substrate is formed to adhere to a film; the reactive diluent enhances the crosslinking degree of the release coating so as to improve the flexibility and adhesive force of the coating, and the assistant improves the leveling property of the coating, so that the coating matrix has a flat surface, and the aluminum layer is completely stripped from the film. The durable frequency of the coating on the film is increased by 2-3times, the coating frequency is reduced, the production efficiency is improved, and the problem of low production efficiency of the vacuum aluminized paperboard due to the fact that the performance ofthe existing release coating is not suitable is solved.

Description

【Technical field】 [0001] The invention relates to the technical field of release coatings, in particular to a special UV release coating for PET or BOPP films and a preparation method thereof. 【Background technique】 [0002] Vacuum aluminum-coated paper is a novel green packaging material that has been widely used in the international packaging industry since the 1980s. Because it adopts the method of vacuum aluminizing, the surface of the cardboard is only covered with a thin, compact and bright aluminum layer of 0.25 microns to 0.3 microns. The vacuum aluminized paper formed in this way has a noble and beautiful metallic texture and is degradable. , Recyclable environmental protection properties, is a green packaging material. [0003] Vacuum aluminum-coated paper is divided into two types according to its production process: direct evaporation method (aluminized on paper surface) and transfer evaporation method (aluminized on film surface). The direct method is to put th...
