Abstract

The invention discloses a UV (Ultraviolet)-thermoplastic resin composite laser aluminum-plated coating composition. The coating composition comprises the following components in parts by weight: 20-80 parts of light-cured resin, 0-50 parts of thermoplastic resin, 1-30 parts of light initiator, 20-200 parts of diluting agent and 0-10 parts of auxiliary agent. Compared with the prior art, the UV-thermoplastic resin composite laser aluminum-plated coating composition can realize a groove with a mould pressing depth so that the formed laser pattern stereoscopic impression is strong; furthermore, the UV-thermoplastic resin composite laser aluminum-plated coating composition adopts light-cured cross-linking to form a film and the heat resistance of the coating is good; and a laser pattern is not easy to deform by heating in a use process so that the timeliness of a laser aluminum-plated film is long.

Description

UV-thermoplastic resin composite citicall limited aluminium paint compsn

Technical field

The present invention relates to a kind of composite citicall limited aluminium paint, relate in particular to a kind of UV-thermoplastic resin composite citicall limited aluminium paint compsn.

Background technology

PET citicall limited aluminium film relies on its functions peculiar property and the sense of outward appearance intensive metal, dazzling laser effect to occupy a tiny space at packaging field always, is widely used in novel housing material fields such as tobacco and wine, food, makeup, tealeaves, gift.The basic property of composite citicall limited aluminium paint is its tack and mold pressing effect, and tack comprises two portions: coating is to the sticking power of basement membrane (being generally the PET film), and aluminium coated is to adhesive force of coatings; The mold pressing effect is meant through mould pressing process and on coating, demonstrates the holographic laser effect.

Existing composite citicall limited aluminium paint is a solvent-based system, and in a large number with an organic solvent, volatile organic matter (VOCs) content height causes severe contamination to producing with environment for use on the one hand, also exists the problem that solvent cost is limited by the international oil price fluctuation on the other hand.In addition, because of containing solvent in the coating, need baking oven that solvent is dried during use, make the coating film forming, this process consumes mass energy; And UV coating has the environmental protection that is superior to solvent based coating and energy-conservation advantage has become extensive common recognition.

The solvent-borne type citicall limited aluminium paint is when making the holographic laser effect through mould pressing process; Coating is film forming; Adopt hot pressed technology to extrude laser effect at film forming coating patrix; On film forming coating, extrude very dark groove and be difficult to, so generally form the groove all more shallow (degree of depth is all at nano level) on the laser pattern coating.And now Along with people's to packing require increasingly highly, the very laser pattern of deep trench (degree of depth is a micron order) has appearred, the existing compound radium-shine coating of solvent-borne type can not satisfy production requirement.The existing PE of employing expects the alternative dark groove of conventional solvent type coating process mold pressing of pouring membrane process, but the laser pattern that adopts the making of PE material pouring membrane process is out of shape the effect that the back influences laser pattern because of thermo-labile yielding.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned conventional solvent type composite citicall limited aluminium paint and the existence of PE material, a kind of UV-thermoplastic resin composite citicall limited aluminium paint compsn is provided.This UV-thermoplastic resin composite citicall limited aluminium paint compsn is because of adopting the mode film forming of photocuring; So mould pressing process can adopt mold pressing and film-forming to carry out simultaneously; Like this when mold pressing because of coating or liquid, the dark groove of mold pressing just can realize that the laser pattern stereoscopic sensation of formation is strong; In addition; This UV-thermoplastic resin composite citicall limited aluminium paint compsn adopts photocured cross-linked film forming; Coating heat resistance can be good, and in use laser pattern is difficult for temperature distortion, so UV-thermoplastic resin composite citicall limited aluminium paint is done the ageing length of citicall limited aluminium film.
