Problems solved by technology

[0008] (3) After printing, the peel strength of PVC and transparent film PVC is poor after hot pressing. After hot lamination, the two layers of PVC film are easy to separate, and the purpose of decoration and protection cannot be achieved.
However, it is easy to peel off after using general water-based ink, which affects product quality
[0009] (4) Ordinary water-based inks have low resolubility, and plate blocking is prone to occur during use
[0010] (5) During use, the adhesion to the substrate is lacking, and it is easy to stick back
[0011] (6) Excessive air bubbles appear during use, which affects the quality of printed products

Abstract

The invention relates to a water-based gravure yellow ink for a soft PVC decoration film. The water-based gravure yellow ink comprises, by mass, 50-60% of anionic aliphatic waterborne polyurethane, 20-25% of an acrylate copolymer emulsion, 1-2% of a surfactant, 1-2% of a nonionic polyurethane thickener, 1-2% of silica powder, 0.1-0.5% of a pH adjuster, 0.05-0.2% of a bactericide, 5-10% of an aqueous polyethylene wax emulsion, 0.1-0.5% of an aqueous defoamer, 0.5-2% of an aqueous leveling agent and 11-16% of a resin-free aqueous nanometer color paste PY83. The invention also provides a preparation method of the aqueous gravure yellow ink. The ink has the advantages of good resolubility, no clogging, good adhesion to a substrate, no after-tack, few bubbles in the use process, convenience inpackaging and construction, high bonding strength, and excellent resistance to yellowing and weathering; and the preparation method has the advantages of simplicity, easiness in control, no grinding process, and improvement of the production efficiency.

Description

technical field [0001] The invention relates to the field of ink coatings, in particular to a gravure surface printing water-based ink for a soft PVC decorative film for floor lamination decoration and a preparation method thereof. Background technique [0002] PVC decorative film is a widely used surface decoration material. First, print on soft PVC, which can have a variety of patterns and embossing. On the hydraulic laminating machine, the completely dried PVC printing surface and a layer of PVC transparent film, PVC non-printing surface and a decorative substrate are heated. Pressure bonding, the temperature of the hydraulic laminating machine is 180-200 ° C, and the time is 30 minutes. Then apply a layer of UV varnish to the laminated sheet to make the surface of the matte film scratch-resistant and easy to clean. Mainly used in the field of floor tiles, there are a variety of patterns such as wood grain, pearlescent, marble, gold and silver brushed, leather grain and...
