Bei der Herstellung von Schichtpreßstoffen ist es vor allem hinsichtlich der Erzielung einer hohen Abriebfestigkeit der Oberfläche weitgehend üblich, über dem beharzten Dekorbogen eine ebenfalls harzimprägnierte Deckschicht (=Overlayschicht) zu verpressen. Als solche ist ein ungefülltes, niedriggrammiges sowie stark saugfähiges Rohpapier aus gebleichtem Natronzellstoff oder Baumwollinters geeignet. Im verpreßten Zustand soll der beharzte Deckbogen vollkommen transparent erscheinen. Der Einsatz der Overlayschicht bedingt neben zuweilen schwerwiegenden kalkulatorischen Nachteilen auch oftmals technische Schwierigkeiten. Diese treten vor allem bei der Herstellung einfarbiger Schichtpreßstoffe auf, bei denen die Deckschicht, besonders bei nicht fachgerechter Beharzung und Verpressung, die Klarheit sowie Egalität der Färbung merklich beeinträchtigen kann.In the production of laminates, it is above all with a view to achieving a high level of abrasion resistance The surface is largely common, with a resin-impregnated one above the resin-coated decal sheet Top layer (= overlay layer) to be pressed. As such, it is an unfilled, low-gram one as well as highly absorbent base paper made of bleached soda cellulose or cotton lint are suitable. in the When pressed, the resin-coated cover sheet should appear completely transparent. The use of the Overlay layer often has serious accounting disadvantages as well as technical ones Trouble. These occur mainly in the production of single-colored laminates which the top layer, especially in the case of improper resin coating and pressing, the clarity and can noticeably affect the levelness of the coloration.
Aus der Auslegeschrift 1 053 303 ist ein Verfahren zur Herstellung von für die Oberflächenveredlung geeigneten aminoplastharzimprägnierten Papier- oder Gewebebahnen bekannt, das dadurch gekennzeichnet ist, daß die Trägerbahnen in einem ersten Arbeitsgang in der wäßrigen Lösung eines niedrig ankondensierten Melaminharzes, die gegebenenfalls noch fließverbessernde Zusätze enthält, imprägniert werden. In einem zweiten Arbeitsgang wird sodann mit der Lösung eines höher kondensierten Melaminharzes, die zusätzlich mit Härtersubstanzen versetzt ist, auf die Oberfläche eine Harzdeckschicht aufgebracht.From Auslegeschrift 1 053 303 a method for the production of for surface finishing is suitable aminoplast resin-impregnated paper or fabric webs known, characterized in that is that the carrier webs condensed in a first step in the aqueous solution of a low Melamine resin, which may also contain additives to improve flow, are impregnated. In a second step is then with the solution of a higher condensed melamine resin, which is additionally mixed with hardening substances, a resin top layer is applied to the surface.
Dieses Verfahren hat den Nachteil, daß die Beharzung der Trägerbahnen in zwei getrennten Arbeitsphasen durchgeführt werden muß, die eines erheblichen apparativen Aufwandes bedürfen. Als weiterer schwerwiegender Nachteil kommt hinzu, daß für die Beharzung der Trägerbahnen zwei verschiedenartige Harztypen verwendet werden müssen. Endlich weisen bekanntermaßen mit Härtern versetzte Melaminharzlösungen nur eine relativ geringe und daher oft betrieblich unzulängliche Beständigkeit der Lösungen auf.This method has the disadvantage that the resin coating of the carrier webs must be carried out in two separate working phases, one of which is a considerable one require equipment effort. Another serious disadvantage is that for the Resin coating of the carrier webs two different types of resin must be used. Finally wise As is known, melamine resin solutions mixed with hardeners are only relatively small and are therefore often operational inadequate stability of the solutions.
Überraschenderweise wurde nun gefunden, daß eine aminoplastharzimprägnierte Trägerbahn mit
harzangereicherter Oberfläche in einem Arbeitsgang und unter Verwendung von nur einer Harzlösung
dadurch hergestellt werden kann, daß man für die Imprägnierung der Trägerbahn Beharzungslösungen
auf Basis von Aminoplastharzen verwendet, die durch Zusatz eines mit der Lösung verträglichen
organischen, makromolekularen Verdickungsmittels auf eine Viskosität von etwa 195 bis 297 cP eingestellt
sind. Als besonders geeignete Zusätze dieser Verfahren zur Herstellung
von Trägerbahnen für SchichtpreßstoffeSurprisingly, it has now been found that an aminoplast resin-impregnated carrier web with a resin-enriched surface can be produced in one operation and using only one resin solution by using resin coating solutions based on aminoplast resins for the impregnation of the carrier web , macromolecular thickener are adjusted to a viscosity of about 195 to 297 cP. As particularly suitable additives in these manufacturing processes

Art erwiesen sich vor allem Celluloseäther sowie Polyacrylamide, die partiellen Verseifungsprodukte der letzteren, Polyacrylate, Polyvinylpyrrolidon und Polyvinylalkohol, weil diese Substanzen die Beständigkeit der Kunstharzlösungen nicht beeinträchtigen.In particular, cellulose ethers and polyacrylamides, the partial saponification products, were found to be type of the latter, polyacrylates, polyvinylpyrrolidone and polyvinyl alcohol because of these substances' resistance of the synthetic resin solutions.
Ein Dekorpapier aus hochgefülltem und gebleichtem Natronzellstoff mit einem Rohgewicht von 150 g/m2 wird im Tauchverfahren in einer Tränkanlage mit horizontal angeordnetem Trockenkanal in einer Lösung imprägniert, die wie folgt zusammengesetzt ist:A decorative paper made of highly filled and bleached soda cellulose with a raw weight of 150 g / m 2 is impregnated in a solution that is composed as follows in a soaking system with a horizontally arranged drying tunnel:
0,5 kg eines Celluloseäthers (»Tylose« KN 2000 der Firma Kalle & Co., Wiesbaden) werden in 50 kg Wasser angeteigt und diese Paste in 323 kg Wasser eingerührt. Hierauf werden 580 kg eines wasserlöslichen Melamin-Formaldehyd-Harzes zugegeben und die Lösung bei Raumtemperatur oder Erwärmen auf 60 bis 65° C fertiggestellt. Anschließend wird unter Rühren mit 42 kg n-Butanol und 5 kg Schwefelsäureester-Na-salz des Oxystearinsäure-äthylanilids versetzt. 0.5 kg of a cellulose ether ("Tylose" KN 2000 from Kalle & Co., Wiesbaden) are used in 50 kg Make a paste with water and stir this paste into 323 kg of water. Thereupon 580 kg of a water-soluble Melamine-formaldehyde resin added and the solution at room temperature or warming up 60 to 65 ° C completed. Then, while stirring, 42 kg of n-butanol and 5 kg of sulfuric acid ester sodium salt are added of the oxystearic acid ethylanilide added.
Die frisch angesetzte Beharzungslösung besitzt eineThe freshly prepared resin solution has a
So Viskosität von 227 cP, die im Laufe von 20 Stunden auf 255 cP ansteigt. Vor Eintritt in den Trockenkanal wird das getränkte Papier auf der RückseiteSo viscosity of 227 cP over the course of 20 hours increases to 255 cP. Before entering the drying tunnel, the soaked paper is on the back

stark abgestrichen. Das getrocknete Papier weist ein Endgewicht von 360 g/m2 auf.heavily streaked. The dried paper has a final weight of 360 g / m 2 .
Die Verpressung zu beschichteten Holzspan-, Holzfaserplatten sowie Schichtstoffen mit Phenolharzkern bei Temperaturen von 130 bis 170° C unter Drücken zwischen 15 und 100 kg/cm2 ergibt Oberflächen von gutem Glanz und Verlauf sowie ausgezeichneter Klarheit der Färbung bzw. des Druckes.The compression to coated wood chipboard, wood fiber boards and laminates with a phenolic resin core at temperatures from 130 to 170 ° C under pressures between 15 and 100 kg / cm 2 results in surfaces with good gloss and flow and excellent clarity of coloration or print.
Verwendet man im obigen Beispiel an Stelle eines Celluloseäthers etwa die doppelte Menge eines Polyacrylamide vom K-Wert 150 (dabei besitzt die Beharzungslösung anfangs eine Viskosität von 195 cP, die auf 297 cP innerhalb 20 Stunden ansteigt) oder etwa die 11- bis 12fache Menge Polyvinylpyrrolidon (wobei in diesem letzteren Fall der Zusatz von n-Butanol entfällt), so erhält man ein Dekorpapier von ähnlich wertvollen Eigenschaften.If in the above example, instead of a cellulose ether, about twice the amount of a polyacrylamide is used with a K value of 150 (the resin solution initially has a viscosity of 195 cP, which increases to 297 cP within 20 hours) or about 11 to 12 times the amount of polyvinylpyrrolidone (whereby in this latter case the addition of n-butanol is not required), a decor paper of similar is obtained valuable properties.
