UV(ultraviolet) metal decorating offset print ink

Abstract

The invention belongs to the technical field of ink printing, and particularly relates to UV(ultraviolet) metal decorating offset print ink. The UV metal decorating offset print ink is prepared from the following material components in parts by weight: 19 parts of polyester acrylate resin, 41-50 parts of special acrylic resin, 4-4.5 parts of talcum powder, 1.9-10.4 parts of SR9020, 5-6 parts of photoinitiator 907, 2-3 parts of photoinitiator ITX, 1 part of photoinitiator BDK, 0-3 parts of photoinitiator 369, 0.1 part of 510 accessory ingredient and 10.4-17.3 parts of colour pigment, wherein the colour pigment is one of pigments of four colors, the red pigment is a magenta pigment, the yellow pigment is a centrolecithal pigment, the sky blue pigment is a bocour blue pigment, and the black pigment is a mixture of the bocour blue pigment, a carbon black pigment and a purple pigment. The UV metal decorating offset print ink has the beneficial effects that good adhesive force is achieved, after one hundred tests, the print ink achieves a 5B level, i.e., no ink falling phenomena happen, meanwhile, post processing requirements are met, and an ink membrane does not crack through simple mechanical stretching.

Description

technical field [0001] The invention belongs to the technical field of ink printing, and in particular relates to a UV offset printing ink for iron printing. Background technique [0002] At present, UV curing technology is known as a new green industrial technology for the 21st century due to its high efficiency, wide applicability, economy, energy saving, and environmental friendliness. However, ordinary domestic iron printing inks are cured by heating and baking, which requires a lot of energy and does not conform to the national industrial adjustment policy. According to a conservative estimate by the China Metal Packaging Association, there are more than 2,000 iron printing production lines in China, which consume 150 million cubic meters of liquefied petroleum gas every year. Printing and curing requires a post-baking oven, which provides a high temperature of 130-210 degrees, and the printed matter needs to be baked in the oven for 15-20 minutes. The instant curing ...

AI Technical Summary

Problems solved by technology

The instant curing of UV ink does not require a lot of energy consumption. It is estimated that using UV ink will save 70% energy than ordinary iron printing ink, and the energy saving effect is obvious. It can be seen that the UV curing system can save a lot of production space; improving production efficiency is the biggest benefit of the UV curing system. Ordinary iron printing inks need to be baked in the oven for 15-20 minutes, and it is difficult to increase the printing speed of the printing machine. The speed of the printing machine is only 2000 sheets / hour, the production efficiency is low, and the energy consumption is large
