Problems solved by technology

Although the current laser transfer composite aluminum foil paper has the above advantages, the transfer coating used in its production process is still solvent-based, and there are still harmful substances in the coating, and the drying volatiles in the production process also pollute the environment. The transfer coating It is composed of a release material and a protective laser layer coating with a secondary coating process, and there are relatively many processes

Embodiment 1， Embodiment 1

[0007] Example 1, Example 1, extract raw materials according to the following weight ratio: 1-20 parts of water-soluble amino resin, 8-12 parts of water-soluble polyurethane resin, 8-12 parts of water-soluble alkyd resin, 26 parts of water-soluble acrylic resin -30 parts, 8-12 parts of cellulose resin, 8-10 parts of additives, 0-10 parts of colorants, 26-30 parts of co-solvents, 30-80 parts of water, made into water-based by synthesis, wetting and dispersing, and blending Laser transfer coating, which is suitable for transfer and compounding of paper, cardboard, fabric, leather and other substrates.

Embodiment 2

[0008] Example 2, raw materials are extracted according to the following weight ratio: 10 parts of water-soluble amino resin, 10 parts of water-soluble polyurethane resin, 5 parts of water-soluble alkyd resin, 30 parts of water-soluble acrylic resin, 10 parts of cellulose resin, auxiliary agent 10 parts, 2-10 parts of pigment, 30 parts of co-solvent, 30-80 parts of water, after synthesis, wetting and dispersing, blending to make water-based laser transfer coating, it is suitable for paper, cardboard, fabric, leather and other substrates transfer compound.

Embodiment 3

[0009] Example 3, the laser transfer coating made in Example 1 and Example 2 is used to be coated on the surface of the carrier film, such as PET, BOPP and PA, etc., dried and crosslinked by heating (80-120°C) After curing into a film, it is molded on a laser molding machine at a temperature of 80-120°C, and then aluminum-plated in a vacuum aluminum plating machine, and then compounded with various types of paper, cardboard, fabric, leather and other substrates. After the complex is dried, the carrier film is peeled off from the complex, and the carrier film can be returned to the previous first process to continue to be used as a carrier film repeatedly. After the carrier film is peeled off, the remaining complex is an environmentally friendly laser transfer compound. Aluminum foil paper, it has a strong metallic feeling, high gloss, strong adhesion to the aluminized layer, good surface wear resistance and reprinting performance, high binding force with ink, and the printed in...

Abstract

The invention relates an environmental protection laser transferred composite aluminum foil paper and the preparing technique, mainly solving the problems of the environment pollution and complicated technique caused by separant coating and laser layer protection coating of the existing commonly used solvent laser transferred composite aluminum foil paper. Its mixing proportion (by weight) of the raw materials is: water soluble amino resin 1-20 (or water soluble polyurethane resin 1-30, or water soluble alcohol acid resin 1-30, or water soluble acrylate resin 1-40, or cellulose resin 1-20), assistant 1-10, pigment 0-10, auxiliary solvent 1-30, and water 30-80, or their arbitrary combination, through synthesizing and wet-dispersing to mix into a water laser transfer coating, coating the transfer coating on a carrier thin film, drying, cross-linking curing, laser-mould pressing, and aluminizing to obtain the laser composite aluminum foil paper. It has the characters of improving environmental protection performance, simplifying producing process, saving energy sources, reducing production cost, stable production quality, etc.

Description

technical field [0001] The invention relates to a laser transfer composite aluminum foil paper coating and a preparation process thereof, in particular to an environment-friendly laser transfer composite aluminum foil paper and a preparation process thereof. Background technique [0002] In the early 1980s, the transfer composite aluminum foil paper invented abroad was used as a packaging material. Because of its superior performance such as environmental protection, energy saving, and economy, it gradually replaced pure aluminum foil paper and plastic aluminized film composite aluminum foil paper. It has also been promoted in China in recent years. With the development of science and technology, laser laser molding technology is combined to transfer composite aluminum foil paper, and laser transfer composite aluminum foil paper has been developed. Although the current laser transfer composite aluminum foil paper has the above advantages, the transfer coating used in its pro...
