Embodiment 1

[0020] A partial UV printing process on the surface of metallic ink, the process comprises the following steps:

[0021] (1) Add 12wt% styrene-acrylic acid polymer, 0.5wt% modified silica-polyethylene wax copolymer and 8wt% self-crosslinking emulsion to the UV base oil, and react at minus 20°C to obtain improved Sexual UV primer with a matte finish;

[0022] (2) After brushing a layer of metal ink on the material to be printed, apply the above-mentioned modified UV base oil, dry it by infrared radiation, and then perform partial UV varnish coating by screen printing, and then apply it with UV light. The product is obtained after irradiation and drying, and the product can optionally present glossy luster and matte luster.

[0023] The above-mentioned modified silicon dioxide-polyethylene wax copolymer is made of polyethylene (PE) ultrafine powder wax, reacted at a temperature of 80°C and a pressure of 3P, and emulsified for 6 hours, while adding a modified silicon dioxide liq...

Abstract

The invention relates to a local UV printing process for the surface of metal printing ink, which comprises the following steps of: (1) adding styrene-acrylic polymer, modified silica-polyethylene wax copolymer and self-crosslinkable emulsion, and reacting at the temperature of between -10 and 30 DEG C to obtain modified UV carrier oil in muted color; and (2) coating a layer of metal printing ink on an object to be printed, coating the modified UV carrier oil, drying by radiating infrared rays, performing local UV varnish coating in a screen printing mode, and drying by radiating UV rays to obtain the product, wherein the product has a bright color or muted color. Compared with the prior art, the process has the advantages of muted color and bright color decoration effects, and the like.

Description

technical field [0001] The invention relates to a UV printing process, in particular to a partial UV printing process on the surface of metallic ink. Background technique [0002] UV screen printing ink was developed in the late 1970s. Once it came out, it brought about earth-shaking changes in the entire screen printing field. The technology uses UV radiation to transform fluid-like printing inks into a nearly 100% solid ink film, thus greatly reducing VOCs (volatile organic compounds) emitted into the atmosphere. [0003] Most ink manufacturers today believe that UV inks have stronger advantages than solvent-based inks in terms of environmental protection, health and safety: it does not contain heavy metals, VOC emissions and harmful solvents are relatively low. , Screen cleaning and recovery process does not need to use too much irritating cleaning agent, ink curing efficiency is high, compared with solvent-based and water-based inks using thermal dryers, UV drying consu...
