Embodiment Construction

[0033] The main raw materials of the invention are: UV water-based binder, pearlescent pigment, photosensitizer, soft water and auxiliary agent.

[0034] UV water-based binder, which plays the role of gluing and connecting, has high gloss retention and good transparency. UV water-based binders can include

[0035] 1]. Modified polyurethane, such as hydroxyl modified, modified polyol, polyol containing olefinic hydrogen, etc., specifically, acrylic polyurethane can be used;

[0036] 2]. High-acid-value acrylic resin, specifically, a high-acid-value acrylic resin that acts as a glue connection and is easy to be compatible with water-based binders can be selected;

[0037] 3]. Aminated acrylic resin, which can be freely mixed with water.

[0038] Pearlescent pigments: It can be matched with offset printing colors according to different color requirements to achieve richer color changing effects.

[0039] The photosensitizer adopts benzoin ethers or benzophenones or a mixture o...

Abstract

The pearlescent UV water-based screen-printing ink consists of pearlescent pigment, UV water-thinned connecting material, photosensitive agent, soft water and proper assistant, and it is printed with screen-printing machine and UV high speed cured. The present invention is superior to background technology, which possesses high power consumption, poor color change effect and inferior physical and chemical performance. The printing ink results in colorful change, expanded anti-fake field, easy identification of truth, excellent copying preventing capacity and good printing adaptability.

Description

technical field [0001] The invention relates to a pearlescent UV water-based screen ink. Background technique [0002] At present, the design of pearlescent screen inks at home and abroad is based on a single principle, that is, using UV curing, solvent volatilization, and water-based penetration, and most of them are printed on flat screen printing machines. When printing, the base ink is printed first. On the substrate, the bonding strength is not enough. The printing objects are mainly disposable commodities, and the circulation time is short, so the physical and chemical properties are not considered perfectly. When manufacturing and using, it will pollute the environment and be harmful to human health. With the change of printing method, the adaptability of ink is also poor. Ordinary screen inks are mostly UV inks, solvent-based inks or water-based inks, and UV water-based inks have not been reported yet. UV ink curing power is relatively large, 0.60kw / cm 2 ; Ordina...
