Definitions
- the invention relates to a process for drying a dispersion varnish and / or an ink on a substrate.
- Fastness means chemical and physical resistance against chemical substances and against mechanical and thermal stress as well as resistance to sealing of films.
- UV paints used are only because of their chemical structure conditionally suitable for use in food packaging.
- oligomers and prepolymers may remain in the paint, resulting in deterioration smell and taste of the packaged food can.
- water-based paints and varnishes do not have this disadvantage on. They are low in migration and low in odor and therefore contribute easily Food packaging used.
- the object of the invention is to provide a method for drying a Dispersion varnish and / or a printing ink on a substrate to provide, by means of which high gloss at high printing speed can be achieved.
- the object could surprisingly be achieved by a process for drying a dispersion varnish and / or a printing ink on a printing substrate, which is characterized in that a NIR (near infrared) dryer with a wavelength range of 0.8-2.0 microns, preferably 0.8-1.2 microns, and a radiation density of 200 - 1000 kW / m 2 is used and the NIR dryer is a TL (thermo-air) dryer and / or an IR dryer upstream or downstream / will ,
- a NIR near infrared
- Such a dryer is described for example in DE 198 07 643 A1.
- Preferred is a method in which the radiation density of the dryer 400 - 1000 kW / m 2 .
- Another essential advantage of the invention lies in the rapid networking the reactive groups in the paint or the paint due to the high energy density of the Dryer. Rapid crosslinking of the reactive groups leads to achievement high fastnesses of the dried lacquers or color layers.
- Very high layer thicknesses of the paints or varnishes also have the Advantage that good barrier properties are achieved.
- barrier properties can be directed against water, steam, fats, gases, etc. and protect the packaged goods in an excellent way.
- a special case of this Barrier properties are flavoring, whereby the layers of colors or varnishes ensure that the flavorings of the filling material in the packaging remain.
- Another advantage given by the invention is the achievement of Matt-gloss effects.
- a targeted insufficient Wetting of aqueous lacquers on special oil-based printing lacquers a good Matte effect achieved, which works particularly well in addition to strong shiny surfaces.
- inventively drying paints with high layer thickness necessary.
- the TL (thermo-air) dryer with extraction and / or the IR dryer are used the support of the drying process.
- the TL dryer is used for accelerated Removal of moisture, the IR dryer of preheating.
- the method characterized in that before or after drying on the dispersion varnish the ink is printed.
- the dispersion varnish and / or the Printing ink printed in offset, flexo, stitch, gravure, screen or pad printing become.
- the paint or the printing ink is preferably used with a layer thickness of 0.5 to 50 .mu.m, particularly preferably 3 to 30 .mu.m wet film layer applied.
- Such a dispersion varnish can 1-80 wt .-%, preferably 1-60 wt .-% of a styrene-acrylate copolymer in the form of an aqueous dispersion, 0-60% by weight, preferably 0-40% by weight, of a styrene-acrylate copolymer in the form of an aqueous resin solution, 0-10 wt .-%, preferably 0-5 wt .-% waxes 0-10% by weight, preferably 0-5% by weight wetting agent, 0-5 wt.% Plasticizer, 0-10% by weight, preferably 0-5% by weight of glycol ether, 0-10% by weight of glycols, 0.1-3% by weight, preferably 0.1-2% by weight defoamer, 0.1-4 wt .-%, preferably 0.1-2 wt .-% neutralizing agent, 0-1 wt% preservative and 0-20% by weight of water include
- a specially adapted to the process of the invention ink can 1-40% by weight of one or more organic or inorganic pigments, 1-80% by weight of a styrene-acrylate copolymer in the form of an aqueous dispersion, 0-60% by weight of a styrene-acrylate copolymer in the form of an aqueous resin solution, 0-10% by weight of waxes 0-10 wt% wetting agent, 0-5 wt.% Plasticizer, 0-10% by weight of glycol ether, 0-10% by weight of glycols, 0.1-3% by weight defoamer, 0.1-4% by weight of neutralizing agent, 0-1 wt% preservative and 20% by weight of water include.
- the lacquer or the printing ink comprises additionally 1-10% by weight of a dihydric or higher alcohol.
- the lacquer or the printing ink comprises 1-5 wt .-% dipropylene glycol monomethyl ether and / or 1-5 wt .-% glycerol and / or 1-5% by weight of propylene glycol.
- copolymers and polymers used in the coatings and inks are used in used different molecular weights.
- the copolymers In the aqueous polymer dispersions the copolymers have a molecular weight of over 100,000 g / mol.
- the copolymers In the aqueous resin solutions, the copolymers have a molecular weight of over 1,000 g / mol.
- the polymers and polymer dispersions used can also reactive groups such as ketofunctional groups and amine groups contain.
- the polymers or copolymers can be selected from a wide range of monomers be constructed.
- glycols propylene glycol or ethylene glycol can be used, as Glycol ether is preferably used dipropylene glycol monomethyl ether.
- Suitable co-solvents are alcohols, such as, for example, ethanol or isopropanol be used.
- Neutralizing agents such as amines or ammonia are used.
- the printing substrate with a Conveying speed of 1-25 m / s, preferably from 2-15 m / s promoted.
