Pure water gravure printing ink for printing PVC decorative film and preparation method thereof

Abstract

The invention provides pure water type gravure cyan ink for printing PVC decorative films which is prepared from the following materials. The pure water type gravure cyan ink for printing PVC decorative films comprises, by mass parts, 5 to 20 parts of cyan pigment, 50 to 75 parts of aqueous PVC glue, 20 to 30 parts of aqueous polyurethane resin, 10 to 30 parts of aqueous epoxy resin, 15 to 35 parts of deionized water, 1 to 2 parts of antifoaming agents, 1 to 2 parts of dispersing agents and 1 to 1.5 parts of surface active agents. The preparation method includes that all the materials are blended and stirred equably. After being grinded and dispersed, if quality testing is eligible, the packaging is filtrated and the pure water type gravure cyan ink is finished. The pure water type gravure cyan ink of the implement example of the pure water type gravure cyan ink and preparation method of pure water type gravure cyan ink for printing PVC decorative films is of safety and environmental protection and the formula doesn't contain any organic resin and aqueous epoxy resin. Besides, the pure water type gravure cyan ink of the implement example of the pure water type gravure cyan ink and preparation method of pure water type gravure cyan for printing PVC decorative films strengthens wetting effect for cyan pigment and meanwhile is of good abrasive resistance and film-forming property.

Description

technical field [0001] The invention relates to the field of ink processing, in particular to a pure water gravure ink for printing PVC decorative films and a preparation method thereof. Background technique [0002] PVC decorative film is a widely used surface decoration material. Firstly, it is printed on PVC, which can have various patterns and embossing patterns. On the double stick laminating machine, the completely dried PVC printed face mask and a layer of PVC transparent film are heated and pressed together. The temperature of the vat of the laminating machine is 180-200°C, and then the laminated film is firmly adsorbed on the surface of the building material through the vacuum suction process, so as to decorate and protect the building material. High-end office furniture, cabinet doors, bathroom cabinet doors, home decoration sets of doors, decorative panels and other building materials can be decorated with it to meet people's different daily needs.

AI Technical Summary

Problems solved by technology

[0004] However, PVC decorative films currently have the following deficiencies: PVC solvent-based inks are often used for printing PVC decorative films. Human body is healthy, so it is better to use water-based ink instead of solvent-based ink to reduce VOCs emissions and be more environmentally friendly

However, there are two problems with the use of water-based inks. One is that the drying rate of water-based inks is low and cannot be dried quickly, which invisibly prolongs the working hours, which is time-consuming and labor-intensive, and also delays the smooth progress of subsequent processes.

The second is that after printing, the peeling strength of PVC and transparent film PVC is poor. When vacuum forming, the two layers of PVC film will be separated, and the purpose of decoration and protection cannot be achieved.

Generally, when PVC is bonded, the temperature is 180-200°C, so the ink is required to maintain good performance under high temperature environment, but it is easy to peel off after using water-based ink.
