Abstract
The invention discloses printing ink matched with a glazing agent, which comprises the following components: pigment, polyhydroxy monomethacrylate, dimethyl dimethoxy silane, boric acid, bisphenol A epoxy resin, polyether glycol, dispersing wetting agent, antioxidant and oily solvent; the glazing agent comprises; waterborne polyurethane, waterborne isobutyl acrylate, a photoinitiator and polyether amine. The invention can solve the problem that the UV varnish is not compatible with the printing ink, and the polyether amine contained in the UV curing varnish is contacted with bisphenol A epoxy resin and polyether glycol contained in the printing ink to form internal polymerization between the varnish and the printing ink by pressing a pressure roller in the varnish glazing process and after the varnish glazing, so that the affinity effect between the printing ink and the varnish is improved.
Description
Technical Field
The invention relates to the field of printing, in particular to printing ink matched with a glazing agent.
Background
The offset printing industry is an important branch of the printing industry, mainly in planar printing. With the development of economy and the progress of technology, the offset printing industry has further developed.
With the development of domestic economy and the improvement of the living standard of people, the appearance of a large amount of consumption demands and the increasing demand for advertisements, the demand for the planar printing market has been rising year by year. Currently, the demand for flat printing in the domestic market is dominated by the demand for commercial printing. At the same time, printing demands in other fields such as packaging, magazines, etc. are increasing year by year.
However, offset printing is generally difficult to form an offset printing product with obvious concave-convex feeling, which is determined by the principle of offset printing, which is a transfer printing mode, and unlike gravure printing, gravure printing can realize indentation of a printed matter itself through a printing plate, concave-convex feeling information is only reflected through the thickness of ink in the offset printing transfer printing process, and the ink is excellent in quick drying property and adhesion, so that an ink layer cannot be excessively thick.
On the other hand, the polishing operation is often required after printing, and the production of the polishing agent and the ink is not always the same manufacturer, and even the same manufacturer, the experiment is performed on a single product basis at the time of setup production, and is not considered as a whole. Therefore, the UV curing glazing agent and the printing ink are often not compatible, and once a printed product is bent or exposed to the sun, a peeling phenomenon is easy to occur between the glazing layer and the printing ink layer.
Disclosure of Invention
In view of this situation, the present invention is intended to provide a printing ink capable of increasing the printing thickness and capable of having affinity between a more glossy layer and an ink layer.
In order to solve the problems, the invention increases the viscosity of the ink, increases the size of a screen, increases the adhesion amount of the ink and improves the thickness of the cured ink by adjusting the formula of the ink, and adjusts the formula of the glazing agent to enable the ink and the glazing agent to mutually perform polymerization reaction before UV curing and increase the affinity of the ink and the screen.
Therefore, the smooth concave-convex feeling of printing can be increased, a product with concave-convex feeling can be formed by an offset printing method under the condition that a printed product is not required to be pressed, and the affinity of a glazing layer and an ink layer is ensured.
In particular, the invention provides a printing ink used with a glazing agent, which is characterized in that the printing ink is used with the glazing agent,
the printing ink includes: pigment, polyhydroxy monomethacrylate, dimethyl dimethoxy silane, boric acid, bisphenol A epoxy resin, polyether glycol, dispersing wetting agent, antioxidant and oily solvent;
the glazing agent comprises; waterborne polyurethane, waterborne isobutyl acrylate, a photoinitiator and polyether amine.
In a preferred implementation, the pigment in the printing ink is 10-25 parts, 15-18 parts of polyhydroxy monomethacrylate, 14-16 parts of dimethyl dimethoxy silane, 1 part of boric acid, 5-12 parts of bisphenol A epoxy resin, 3-6 parts of polyether glycol, 0.5 part of dispersing wetting agent, 0.5 part of antioxidant and 20-25 parts of oily solvent.
In another preferred implementation, the ratio of each component in the polishing agent is: 8-10 parts of waterborne polyurethane, 30-35 parts of waterborne isobutyl acrylate, 3 parts of photoinitiator and 5-10 parts of polyether amine.
In another preferred implementation mode, the polishing agent further comprises 1.5-2 parts of emulsifying agent, 0.5-1 part of leveling agent, 0.5-1 part of plasticizer and 0.5-1 part of antioxidant.
In another preferred implementation, the gloss agent does not include an epoxy resin and the printing ink does not include a polyetheramine. In another preferred implementation, the gloss agent does not include an epoxy resin and the printing ink does not include a polyetheramine.
In another preferred implementation, the glazing agent further comprises an ultraviolet absorber.
In another preferred implementation, the polyether glycol may be a polyoxypropylene glycol or other polyether glycol,
in another preferred implementation, the ultraviolet absorber may be a benzotriazole mixture or other ultraviolet absorber.
In another preferred embodiment, the antioxidant may be diethyl 3, 5-di-tert-butyl-4-hydroxybenzylphosphonate or other light stabilizer.
In another preferred implementation, the light stabilizer may be 2- (2 ' -hydroxy-3 ' -tert-butyl-5 ' -methylphenyl) or other light stabilizers.
In another preferred embodiment, the pigment may be a yellow pigment such as disazo yellow or hansa yellow, a bright carmine, lake red C, phthalocyanine blue, phthalocyanine green, alkali blue, or the like, carbon black, or the like.
Preferably, a catalyst (which is used for catalytically hardening the two-component paste components contained in the printing ink and the gloss agent, respectively) is further included in the gloss agent, and an organobismuth catalyst or an organotin catalyst may be used as the catalyst.
The first component of the two-component adhesive mentioned above comprises: bisphenol A epoxy resin E-51, polyether glycol N210, an ultraviolet absorber, an antioxidant, a light stabilizer and polyamide or polyether amine as the other component.
Technical effects
According to the invention, on one hand, the ink formula is adjusted, the ink viscosity is increased, the adhesion amount of the ink is increased, the thickness of the cured ink is increased, and on the other hand, the surface hardness of the ink is enhanced by spraying a coating capable of interacting with the ink on the surface, so that the ink part has more obvious concave-convex feeling relative to the ink-free part, and a product with concave-convex feeling can be formed by an offset printing method under the condition that a printed product is not required to be pressed.
The invention can solve the problem that the UV varnish is not compatible with the printing ink, and the polyether amine contained in the UV curing varnish is contacted with bisphenol A epoxy resin and polyether glycol contained in the printing ink to form internal polymerization between the varnish and the printing ink component by pressing a pressure roller in the varnish glazing process and after the varnish glazing, so that the affinity effect between the printing ink and the varnish is improved, and on the other hand, the problem of hardness of the surface of the printing ink after the printing ink is thickened by adopting a screen of 80 ℃, can be solved, so that the printing ink provided by the invention can be matched with the corresponding varnish to realize printing patterns with certain raised sense, namely the gravure effect is realized by offset printing.
