Definitions
- the invention relates to a method for the production of decorative laminates with Syn ⁇ chronporen using a printing ink, which has an additive which prevents the wetting of the printed layer with impregnating resins. It further relates to an ink suitable for carrying out the process and to decorative laminates with synchronous pores obtainable by the process.
- Decor laminates are known in principle. They are available in various forms, i.a. used in the construction and furniture industry. As motifs are widely used wood grains; In addition, stone, ceramic, cork or pure fantasy decors are also common.
- the decor papers used are produced by printing white or colored special papers in the gravure printing process, usually in 3- or 4-color printing, with suitable decors.
- the color last printed here is the so-called pore color, a dark color such as, for example, a dark red or a dark brown with which only the pore design, such as, for example, the wood pulp, is printed.
- the laminate is usually provided with pores in the surface.
- a corresponding pore pattern is engraved in the press plates used for pressing.
- the pattern engraved in the press plate is transferred to the surface of the decorative laminate, so that the surface also has a corresponding pore pattern.
- the engraved pores will not match the printed pore mark.
- the decorative laminate should have so-called "synchronous pores", ie the printed pore pattern should match the actual pores in the surface, as with a natural product, requiring a separate press plate for each printed pattern This procedure is complicated and expensive.
- the decorative papers used also expand during printing and when soaking with the impregnating resin, and depending on the chosen conditions, not always to the same extent.
- the embossed pore structure often does not exactly match the printed pore structure.
- Waxes as additives of gravure inks are known in principle. They are used in particular to improve the abrasion resistance and scratch resistance of the prints. Further details are disclosed, for example, in “Rompp Lexikon Lacke und Druckmaschine", Georg Thieme Verlag Stuttgart 1998, p. 767 ". The quantities used are however small.
- the object of the invention was to provide an improved process for the production of decorative laminates with synchronous pores, which does not have the abovementioned disadvantages. It was also an object to provide a gravure ink suitable for the process.
- a process for preparing decorative laminates with synchronous pores comprising at least the following steps:
- dice-containing decorative laminates have been found which are obtainable by the process.
- a gravure ink which comprises at least one solvent or a solvent mixture, a binder, a colorant and one or more additives, wherein at least one of the additives is effective amounts of an impregnating resin repellent material.
- a suitable white or colored paper is first printed by means of gravure printing with the desired decor.
- Suitable specialty papers for the production of laminates are known to the person skilled in the art.
- a single printed layer can be printed in one color, but preferably several print layers are applied in different colors.
- the decor is printed with a set of differently colored printing inks, for example by means of 3 or 4 color gravure printing techniques.
- the pattern may be wood patterns; but it can also be any other pattern, for example, stone, ceramic, cork or pure fantasy patterns.
- the actual pore structure is usually printed with the uppermost printing layer. This last color is also known to the person skilled in the art as pore color, and is usually a dark printing ink, for example a dark brown or a dark red.
- “gravure ink” is self-explanatory and restrictive at the same time.
- “Low-pressure inks are low-viscosity printing inks which comprise, in a basically known manner, at least solvent, binder and colorant and optionally one or more additives contain relatively low boiling Lö ⁇ seffen. the boiling point is as a rule not more than 140 0 C. the skilled worker the basic principles formulation of gravure inks are known.
- the solvent of the gravure ink (s) used is preferably water or a predominantly aqueous solvent mixture.
- Other components of predominantly aqueous solvent mixtures may be, for example, alcohols.
- the amount of solvent or solvent mixture is usually carries 50 to 80 wt.% Solvent with respect to the sum of all constituents of the low-pressure ink.
- binders for the gravure ink used for the process according to the invention the usual binders for gravure inks can be used. Preference is given to using binders which are soluble or dispersible in water or aqueous solvent mixtures.
- suitable binders include aqueous dispersions of aromatic or aliphatic polyurethanes, casein or casein derivatives, polyvinyl alcohols or polyvinyl alcohol derivatives, polymers and copolymers of acrylic acid or acrylic acid derivatives, such as, for example, acrylates.
- the person skilled in the art makes a suitable choice among the binders which are possible in principle.
- binders are casein or casein derivatives. It is of course also possible to use mixtures of different polymeric binders, provided that the selected binders have no undesired properties in combination with one another.
- the amount of all binders is usually 5 to 20% by weight, based on the sum of all constituents of the printing ink.
- the colorants which can be used are the dyes customary for gravure printing inks, in particular customary pigments.
- examples are organic pigments such as azo, phthalocyanine or isoindoline pigments.
- inorganic pigments such as, for example, titanium dioxide pigments or iron oxide pigments, interference pigments, carbon blacks or metal powders, and of course also mixtures of various dyes or colorants. Soluble organic dyes can also be used.
- the amount of colorant is usually 5 to 25% by weight with respect to the sum of all constituents of the printing ink. In a set of intaglio inks for multicolor printing, each ink in a known manner in color includes a variety of matched colorants.
- the gravure ink may optionally comprise one or more additives typical of printing inks and / or auxiliaries.
- a gravure ink comprising effective amounts of an impregnating resin repellent additive.
- the impregnating resin-repelling additive of the gravure printing ink may be an arbitrary additive which has a sufficient repelling effect on the impregnating resin used to produce the respective decorative laminate, provided that the properties of the gravure ink are not adversely affected by the additive influenced.
- Repulsive means that the wettability of the pressure layer comprising the additive with the impregnating resin is ideally completely eliminated, but it is sufficient for the purpose according to the invention if the wettability is reduced at least to such an extent that clearly visible It will be understood by those skilled in the art that wettability will also depend on the properties of the impregnating resin used An additive which is repellent to an impregnating resin of certain chemical composition does not necessarily repel or at least not so well repel one The person skilled in the art will make a suitable choice depending on the desired properties.
- Impregnating resins for the production of decorative laminates are known in principle to the person skilled in the art. Particular mention should be made of phenol-formaldehyde resins and melamine-formaldehyde resins. Particularly preferred are melamine-formaldehyde resins or modifi ⁇ ed melamine-formaldehyde resin. Such resins have no inherent color and have excellent water-repellent properties after curing. Melamine-formaldehyde resins are exemplified in Ullmann's Encyclopedia of Indutrial Chemistry, 6P 1 EdL, 2000 Electronic Release "Amino Resins 7.2. Melamine Resins ". Melamine-formaldehyde resins are commercially available, for example under the brand Kaurit ® (BASF AG).
- BASF AG Kaurit ®
- repellent additives have proven particularly waxes.
- Both natural and preferably synthetic waxes can be used.
- natural waxes include beeswaxes, paraffinic waxes, montan waxes or camauba waxes.
- suitable synthetic waxes include polyethylene waxes and polypropylene waxes or the corresponding oxidized products, Teflon waxes or silicone waxes.
- polyethylene waxes or “polypropylene waxes” includes, of course, those products which, in addition to ethylene or propylene as main constituents, have further comonomers for finely controlling the properties of the wax.
- the waxes are used in the form of fine particles.
- the average particle size is preferably ⁇ 30 ⁇ m and particularly preferably ⁇ 20 ⁇ m.
- coarse particles can be generated on the one hand in situ, for example by intensive dispersion of the wax in the solvent and optionally other components of the printing ink by means of suitable dispersing units.
- Polyethylene waxes are preferably added in the form of finely divided micropulves.
- Micronized polyethylene waxes are commercially available, for example as aqueous dispersions. Preference is given to micronized polyethylene waxes having a mean particle size of from 0.5 ⁇ m to 20 ⁇ m.
- Such polyethylene waxes or their aqueous dispersions are commercially available, for example under the brand Lu wax ® (BASF AG).
- the impregnating resins repellent additives are generally used in an effective amount, i. the amount is determined by one skilled in the art, so that a sufficient repellent effect on the impregnating resin results. As a rule, this requires at least a few percent of all components of the gravure printing ink, generally at least 2 to 3 percent by weight.
- waxes in particular polyethylene waxes, in an amount of 6 to 15 wt .-% with respect to all components of the gravure ink used, even if in exceptional cases, even in a lesser amount of an effect can be achieved.
- Preferred is an amount of 8 to 14 wt .-% and particularly preferably from 10 to 13 wt .-%.
- the additives mentioned have proven particularly useful in combination with melamine-formaldehyde resins, but also have an effect with other impregnating resins such as e.g. Phenol-formaldehyde resins.
- the production of the intaglio printing ink according to the invention can be carried out in a manner known in principle by intensive mixing or dispersion of the constituents in customary apparatuses, for example dissolvers, stirred ball mills or a three-roll mill.
- customary apparatuses for example dissolvers, stirred ball mills or a three-roll mill.
- a concentrated pigment dispersion with a part of the components is first prepared, which is further processed later with further constituents and further solvent to the finished ink.
- the decor is processed in a manner known in the art to a decorative laminate.
- the paper is first soaked with the impregnating resin.
- the surface of the paper is not wetted with the impregnating resin in the areas which were printed with the printing ink containing the repelling additive, or at least to a lesser extent than the other areas.
- the impregnated decor paper is laminated with the side facing away from the printed layer side under pressure and temperature to a suitable carrier material and cured.
- Both steps can be performed in parallel, or it can first be laminated and then cured.
- the support material may on the one hand be wood supports such as, for example, chipboard or high- or medium-density fiberboard. But it can also be a special thick paper, so-called kraft paper. In the latter case, the laminate obtained by means of the kraft paper after the production is glued onto a suitable wooden support in a further step.
- overlay papers ie very fine papers, which are placed on the decor paper.
- the joining and curing of the laminate takes place in customary, heatable laminating presses. These can be continuous or discontinuous presses.
- the pressure is usually up to 30 bar, in special high-pressure presses up to 360 bar and the temperatures can be up to 220 0 C.
- the temperature during lamination is 150 to 190 0 C.
- press plates engraved with pores are unnecessary, it can press plates are used without pores.
- the skilled person if desired, to achieve special effects, also use press plates with pores.
- the impregnating resin no longer runs on the surface under the conditions of pressure and temperature mentioned above.
- the areas printed with the additized ink remain substantially free even during lamination. This does not rule out that the diameter of the pores after curing may be slightly lower than before hardening or that small amounts of impregnating resin may also enter the additized areas as long as only visible pores remain in the surface.
- the laminate obtainable by means of the method according to the invention has synchronizers, i. the actual pores in the surface are always located exactly where pores have been printed.
