Environment-friendly ultraviolet-cured oil with fluffy tactile impression and production method of environment-friendly ultraviolet-cured oil with fluffy tactile impression

Abstract

The invention provides an environment-friendly ultraviolet-cured oil with a fluffy tactile impression and a production method of the environment-friendly ultraviolet-cured oil with the fluffy tactileimpression. The environment-friendly ultraviolet-cured oil with the fluffy tactile impression comprises, in parts by weight, 60-90 parts by weight of a modified bifunctional polyurethane acrylate oligomer, 3-10 parts by weight of an ultraviolet initiator, 5-10 parts by weight of an amine co-initiator, 2-5 parts by weight of extinction powder, 5-15 parts by weight of tactile powder, 0.5-1 part by weight of a dispersion agent, 0.5-1 part by weight of a flatting agent and 0.1-1 part by weight of a defoaming agent; and the relative molecular mass of the modified bifunctional polyurethane acrylateoligomer is 2700-3000, and the viscosity at 25 DEG C is 80-150 cps. The tactile oil not only is environmentally friendly, but also has the advantages that a curing source is single, the stability is high, the anti-wear property is excellent, and the fluffy tactile impression is strong.

Description

technical field [0001] The invention relates to a tactile oil, in particular to an environment-friendly ultraviolet light-cured fluff tactile oil and a preparation method thereof, belonging to the technical field of printing inks. Background technique [0002] With the improvement of people's quality of life, there are higher and higher requirements for the packaging of daily necessities. Not only higher requirements are put forward for the texture of packaging paper and the color of packaging printing, but also the packaging is required to have excellent touch. Performance. Therefore, the tactile oil used to make the packaging have a matte look and feel and give the packaging a three-dimensional touch came into being. So far, the use of tactile oils in the printing industry is mainly divided into water-based tactile oils, solvent-based tactile oils, and two-component UV-curable fluff tactile oils. [0003] Water-based tactile oil is a tactile oil with water as the main ca...

AI Technical Summary

Problems solved by technology

[0003] Water-based tactile oil is a tactile oil with water as the main carrier, so a large amount of sewage discharge will be generated during the production process and printing process, polluting water resources, and it is prone to incomplete drying during the printing process, resulting in sticking and non-wearing However, the water-based UV-curable fluff tactile oil, which belongs to the water-based tactile oil, has improved tactility and friction resistance compared with ordinary water-based tactile oils, but in addition to causing water pollution, it also has more effects on the curing source. Requirements, hot air (or infrared) drying and UV curing need to be carried out at the same time, and the energy consumption is large

[0004] Solvent-based tactile oil is a tactile oil with organic solvent as the main carrier, so a large amount of VOCs will be generated during the production and printing process, which will pollute the atmospheric environment, and the solvent in the tactile oil volatilizes during the printing process, which is prone to instability The printed graphics and texts, the yield rate is low

[0005] Two-component UV-curable fluff touch oil only needs to be cured by UV light during the printing process, but its stability is poor, it needs to be prepared before printing, and cannot be stored for a long time, otherwise it will cause turbidity or even agglomeration and curing, which will lead to failure. And the wear resistance and scratch resistance of the printing effect are not stable
