Problems solved by technology

Now, as people's requirements for packaging are getting higher and higher, laser patterns with deep grooves (depth of micron level) have appeared, and the existing solvent-based composite laser coatings can no longer meet production requirements.
Currently, the PE material coating process is used to replace the traditional solvent-based coating process to mold deep grooves, but the laser pattern made by the PE material coating process is not heat-resistant and easy to deform, and the deformation will affect the effect of the laser pattern

Embodiment 1～5

[0044] Embodiments 1 to 5 respectively provide UV-thermoplastic resin composite laser aluminized coating compositions, and the corresponding raw material components and parts by weight of each composition are shown in Table 1;

[0045] The raw material components corresponding to each embodiment were mixed according to their parts by weight, dispersed at a medium speed for 2 hours, and filtered to obtain the corresponding UV-thermoplastic resin composite laser aluminized coating combination.

[0047]

Embodiment 6

[0048] Embodiment 6, performance testing

[0049] Performance tests were performed on the coating compositions prepared in Examples 1-5 and Comparative Example 1 to measure the coating's smoothness, adhesion, aluminizing fastness, sample appearance, and temperature resistance performance parameters.

[0050] The specific performance testing items and corresponding methods are as follows:

[0051] 1. Flatness

[0052] The paint is coated on the pretreated PET film by scraping method, and the coating flatness of the proof is visually inspected.

[0053] Test method: Visually observe the appearance of the test sample.

[0054] Evaluation method: the surface of the sample sheet is smooth and flat as excellent, and the surface is uneven and wrinkled as poor.

[0055] 2. Adhesion

[0056] The paint is coated on the pretreated PET film by scraping method, and the pattern of the embossed plate is pressed on the coating when curing. The adhesive tape method was used to test the ...

Embodiment 7～11

[0073] Embodiments 7 to 11 respectively provide UV-thermoplastic resin composite laser aluminized coating compositions, and the corresponding raw material components and parts by weight are shown in Table 3; Mix several times, disperse at a medium speed for 2 hours, and filter to obtain the corresponding UV-thermoplastic resin composite laser aluminized coating composition.

[0074] The coating compositions prepared in Examples 7 to 11 all have excellent flatness, adhesion, fastness to aluminum plating, appearance of proof sheets and temperature resistance. Moreover, because the film is formed by photocuring, the molding process can be carried out simultaneously by molding and curing. In this way, because the coating is still liquid during molding, deep grooves can be molded, and the formed laser pattern has a strong three-dimensional effect. In addition, the coating adopts photocuring and crosslinking to form a film, and the coating has good heat resistance, and the laser pat...

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

technical field [0001] The invention relates to a composite laser aluminizing coating, in particular to a UV-thermoplastic resin composite laser aluminizing coating composition. Background technique [0002] PET laser aluminized film has always occupied a place in the packaging field due to its unique functionality, strong metallic appearance and dazzling laser effect. It is widely used in the field of new packaging materials such as tobacco and wine, food, cosmetics, tea, gifts, etc. . The basic performance of the composite laser aluminized coating is its adhesion and molding effect. The adhesion includes two parts: the adhesion of the coating to the base film (usually PET film), and the adhesion of the aluminized layer to the coating; the molding effect It refers to the holographic laser effect on the coating through the molding process. [0003] The existing composite laser aluminized coating is a solvent-based system, which uses a large amount of organic solvents. On t...
