Embodiment 1

[0026] The invention provides a kind of environment-friendly water-based ink (white system), by weight, its component system is: the component of described water-based ink comprises:

[0027] Self-crosslinking water-based resin 65.0-79.0%

[0028] Resin-free water-based color paste 0-20.0%

[0029] Defoamer 0.05-0.3%

[0030] pH regulator 0.1-0.5%

[0031] Wetting agent 0.1-0.5%

[0032] Titanium dioxide 0.5-1.0%

[0033] Associative polyurethane thickener 0.1-0.6%

[0034] Co-solvent 1.0-5.0%

[0035] Fungicide 0.05-0.2%

[0036] The balance is deionized water.

[0037] Wherein: the self-crosslinking water-based resin is self-crosslinking water-based polyurethane or self-crosslinking acrylic emulsion, which is the connecting resin of the entire formula system, and its function is to closely connect pigments and the like to the substrate PVC film. After drying, due to its unique self-crosslinking structure, the water-based resin can undergo a self-crosslinking reaction...

Abstract

The invention discloses an environmentally friendly water-based ink. The components include 65.0-79.0% of a self-crosslinking water-based resin, 0-20.0% of a resin-free water-based color paste, 0.05-0.3% of a defoamer, and a pH regulator by weight. 0.1‑0.5%, wetting agent 0.1‑0.5%, titanium dioxide 0.5‑1.0%, associative polyurethane thickener 0.1‑0.6%, cosolvent 1.0‑5.0%, bactericide 0.05‑0.2%, and deionized water. Compared with the existing technology, the water-based ink and its color dilute the adhesion between the gold oil and the PVC film layer, and the anti-sticking performance, water resistance, and alcohol resistance of the ink layer are all improved, and there is no back-sticking after printing and rewinding storage Phenomenon, the transfer printing network is clear, the color is full, the gravure printing is on the PVC film, compared with the natural one, there is no color difference, and the construction is simple.

Description

technical field [0001] The invention relates to a water-based ink, in particular to an environmentally friendly water-based ink used for laminating decorative films on furniture and laminating wall panels. Background technique [0002] The prior art uses water-based inks for gravure printing of PVC decorative films. Compared with solvent-based inks, there are still many deficiencies in use, such as the blockage of the screen by the ink in the printing process, and the discrete blurring of the printing dots due to the poor transferability of the ink. . In addition, due to the presence of water in the formula system, water-based inks have slow printing and drying speeds, poor adhesion to PVC substrates after drying, poor water and solvent resistance, and rewinding and sticking during storage. The domestic invention patent (application number: CN201310089792.X) introduces a certain proportion of co-solvent alcohol (nearly 20% by weight) to solve the problem of ink drying. Alth...
