Abstract
The invention provides a kind of nano modification pure water base gravure ink and its application, the present invention includes aqueous color paste, multi-element, inorganic nano components, nano-resin emulsion, resin dispersion liquid, UV resistant agent, defoamer, pH stabilizers, surfactant (wetting agent), water-based wax liquor, multi-functional coalescents, drier, levelling agent, crosslinking agent, adhesion promoter, pure water and mainly formed.Ink provided by the present invention possesses outstanding printing adaptability energy and layer of ink has raising resistance oxygen, resistance is wet, obstructs action of ultraviolet radiation, through the printing of the flexible package technological process of production, compound, solidification, cutting, packaging protection to products such as food, medicine is can be widely applied to after bag, play and keep content taste not ooze out, not because color change and printing packaging appearance discolouration phenomena occur for long-term storage content, reduce that product is rotten to be occurred, extend shelf life of products and act on.
Description
Technical field
The present invention relates to field of packaging material, in particular to a kind of nano modification pure water base gravure ink and its
Using.
Background technology
Traditional solvent-borne ink can a large amount of volatile emission VOCs, seriously pollute air, economy develop rapidly while ring
Border pollution problem getting worse.Through calculating because discharging more than about 1,000,000 tons of VOCs into air every year with solvent-based ink, by passing
The transformation of emission reduction to(for) control atmosphere pollution thing and VOCs of the solvent-based ink to Environmental-protection water-based ink of uniting is significant.
Common printing-ink no matter solvent-borne type or water-based, simply play the color of the word and pattern to packaging material
Show effect.A large amount of packed articles such as food, medicine need packaging film bag to have fragrant guarantor, resistance oxygen respectively, hinder wet, uvioresistant work(
Energy.And current package and production technique is by shifting to an earlier date from expensive high-isolation film or by high-obstructing coating liquid to film
It is coated with to realize these functions, this there is in extra production technology and production cost waste.
At present, intaglio plate plastics ink technology generally uses the alcohols solvent of addition different proportion to make diluent to solve ink
Existing drying is slow, poor adhesive force, gloss difference, ink fatigue durability is poor, site transfer effect is poor, it is scarce not adapt to high machine speed etc.
Point.But this can only be referred to as alcohol aqueous ink, it is impossible to be referred to as real pure water ink.
In view of this, it is special to propose the present invention.
The content of the invention
The first object of the present invention is to provide a kind of nano modification pure water base gravure ink, described to solve the above problems
Nano modification pure water base gravure ink, do not add any VOCs compositions in production and use, do not add poisonous and harmful element yet,
Also without traditional solvent-borne ink is inflammable, explosive danger, safe and environment-friendly green product is belonged to.The ink have protect fragrant, resistance oxygen,
Hinder wet and anti-ultraviolet function.
The second object of the present invention is to provide a kind of application of described nano modification pure water base gravure ink, ink use
In making high-barrier plastic flexible package, the production requirement to high-barrier packaging is easily can be achieved with, production efficiency is improved, reduces
Production cost can reach even beyond tradition technological effect.Pure water ink of the present invention is that pure water is hardly deposited using diluent
Reduce the cost using solvent in expense, comparatively speaking, comprehensive use cost reduces 20% or so, and flexible package factory is dropped
Low production cost positive effect.
