Abstract

The present invention discloses an UV offset printing ink for plastic printing, and a preparation method thereof, and relates to the field of offset printing, wherein the components of the ink comprise, by mass, 8-15% of a pigment, 20-25% of polyurethane acrylate, 18-29% of polyester acrylate, 19-34% of polyacrylate, 9-15% of a photoinitiator, and 1-3% of an auxiliary agent. According to the present invention UV offset ink pigment component and spectral analysis of light caused by the agent, UV offset printing ink formulations optimized pigment and photoinitiator combinations as well as with the case, viscosity, fluidity, curing time and adhesion fastness as the reference standard, preferably all types of acrylic resin, find the best combination of the resin and with the situation , the components will be reasonable, with a three-roll mill fineness of the ink control 15pm or less, by a plurality of experiments to optimize the ratio, to get the best formula series of ink, the kind of ink curing time is short, adhesion fastness high, in line with production requirements, cut reduces the printing process, environmental protection and good.

Description

A kind of plastic printing UV flexographic ink and preparation method thereof
Technical field
The present invention relates to offset printing field, be specifically related to a kind of plastic printing UV flexographic ink and preparation method thereof.
Background technology
Offset printing UV ink is a kind of feature of environmental protection ink, not containing volatile composition, as solvent or water, color and printing characteristic Master change can not be made, in the process of printing, UV ink easily keeps the stable of color and viscosity, once after before printing ink being adjusted, adjustment workload is on the printer just very little, also without the need to adding other additive again, dried UV ink layer surface has high wear resistance and chemical stability, and there is very high opacifying power and glossiness, but because non-polar plastic surface free energy is lower, in order to increase the attachment fastness of ink at printing product surface, domestic printing enterprise generally adopts the methods such as corona punching to increase its surface energy, thus reach the condition of printing, but so substantially increase printing process, reduce working efficiency, if application number is that CN 201310138279.5 discloses a kind of flexographic ink and preparation method thereof, described flexographic ink is by 65-80 part binder, 1-2 part slack wax, 15-25 part pigment, 1-10 part auxiliary agent A forms, described slack wax comprises oleum lini, mineral oil and beeswax, beeswax is primarily of lipid, free acids, free alcohols and hydrocarbon composition, described slack wax has internal lubrication effect and external lubrication effect concurrently, the more important thing is, under the acting in conjunction of oleum lini, mineral oil and beeswax, prepared slack wax can balance inside and outside lubrication, under the prerequisite not affecting gelation, effective solution flexographic ink sticks the problem of ink roller, effectively can improve printing quality, reduce the cleaning maintenance cost of printing press, improve the working efficiency of printing press, and preparation process is simple, process costs is low, but this kind of ink is appointed and so be there is poor adhesive force, and the phenomenon of easy deinking occurs, and raw material not easily obtains, and raw materials cost is higher.
Summary of the invention
Problem to be solved by this invention is to provide a kind of plastic printing UV flexographic ink and preparation method thereof.
To achieve these goals, the technical scheme that the present invention takes for: a kind of plastic printing UV flexographic ink provided, in described flexographic ink, the massfraction of each component is pigment 8-15%, urethane acrylate 20-25%, polyester acrylate 18-29%, polyacrylic ester 19-34%, light trigger 9-15% and auxiliary agent 1-3%.
Preferably, in described flexographic ink, the massfraction of each component is pigment 10%, urethane acrylate 20%, polyester acrylate 30%, polyacrylic ester 25%, light trigger 13% and auxiliary agent 2%.
A preparation method for plastic printing UV flexographic ink, comprises the steps:
(1) grind: get dry pigment and be placed in grinding machine for grinding 22-35min;
(2) disperse: the pigment after grinding in step (1) is placed in stirrer, then add urethane acrylate, polyester acrylate, polyacrylic ester, light trigger and auxiliary agent respectively and start stirrer stirring 30-50min.
Preferably, described auxiliary agent is one or more in flow agent, dispersion agent, wetting agent, smooth agent.
Adopt technical scheme of the present invention, by the Spectrum Analysis to the pigment in UV flexographic ink component and light trigger, optimize combination and the situation of collocation of pigment and light trigger in UV flexographic ink formula, with viscosity, degree of mobilization, set time and attachment fastness are reference standard, optimize all kinds of acrylic resin, find out best of breed and the collocation situation of resin, each component is carried out reasonably combined, with three-roll grinder, ink fineness is controlled at below 15pm, by multiple optimum experimental proportioning, thus obtain the optimum formula of series ink, this kind of ink solidification time is short, attachment fastness is high, meet production requirement, cut and decrease printing process, the feature of environmental protection is good.
Embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
embodiment 1:
A kind of plastic printing UV flexographic ink, in described flexographic ink, the massfraction of each component is pigment 10%, urethane acrylate 20%, polyester acrylate 30%, polyacrylic ester 25%, light trigger 13%, flow agent 1% and dispersion agent 1%.
A preparation method for plastic printing UV flexographic ink, comprises the steps:
(1) grind: get dry pigment and be placed in grinding machine for grinding 25min;
(2) disperse: the pigment after grinding in step (1) is placed in stirrer, then add urethane acrylate, polyester acrylate, polyacrylic ester, light trigger and auxiliary agent respectively and start stirrer stirring 40min.
Based on above-mentioned, by the Spectrum Analysis to the pigment in UV flexographic ink component and light trigger, optimize combination and the situation of collocation of pigment and light trigger in UV flexographic ink formula, with viscosity, degree of mobilization, set time and attachment fastness are reference standard, optimize all kinds of acrylic resin, find out best of breed and the collocation situation of resin, each component is carried out reasonably combined, with three-roll grinder, ink fineness is controlled at below 15pm, by multiple optimum experimental proportioning, thus obtain the optimum formula of series ink, this kind of ink solidification time is short, attachment fastness is high, meet production requirement, cut and decrease printing process, the feature of environmental protection is good.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
