druck von 2 bis 10 kp/crn verbunden wird, derart daß die Dekorpapierbahn der beheizten Bandpressen-Trommeloberfläche am nächsten liegt und als an die Dekorpapierbahn anschließende MaterijTlbahn eine Vulkanfiberfolienbahn oder eine Bahn aus imprägniertem Karton eingesetzt wird.2
pressure of 2 to 10 kp / cm is connected so that the decorative paper web is closest to the heated belt press drum surface and a vulcanized fiber film web or a web of impregnated cardboard is used as the material web adjoining the decor paper web.

Die Imprägnierung des Dekorpapiers erfolgt dabei" "vor teilft"af\ in zwei Stufen, und zwar in einer Vorimprägnierstufe durch ein in Alkohol gelöstes Melaminharz und in einer Nachiraprägnierstufe durch ein in Wasser gelöstes Melaminharz.The impregnation of the decorative paper is done "" before teilft "af \ in two stages, in a Vorimprägnierstufe by a dissolved in alcohol melamine resin, and in a Nachiraprägnierstufe by a water-dissolved melamine resin.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine vorteilhafte Ausgestaltung des Verfahrens gemäß Hauptpatent anzugeben, bei dem die verwendete Imprägnierung besonders kurze Aushärtezeiten und damit dementsprechend hohe Preßgeschwindigkeiten zuläßt.The object on which the invention is based is to provide an advantageous embodiment of the method according to Specify the main patent in which the impregnation used has particularly short curing times and thus accordingly allows high pressing speeds.

Die der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß die Imprägnierung des Dekorpapiers mit einem Bindemittel erfolgt, das in einer 50 - 70%igen wässrigen Melaminharziösung einen Zusatz von Polyvinylalkohol und als Härter ein Erdalkalisalz einer starken Säure enthält. Dabei ktiriri die Imptfäcnieruno vorteilhaft in zwei Stufen, nämlich in einem Vorimpragnierverk und in einem Nachlackierwerk, erfolcren.The object underlying the invention is achieved in that the impregnation of the decorative paper with a Binder takes place in a 50-70% aqueous melamine resin solution an addition of polyvinyl alcohol and contains an alkaline earth salt of a strong acid as hardener. The Imptfäcnieruno advantageous in two stages, namely in a pre-impregnation plant and in a post-painting plant, to be successful.

In einer vorteilhaften Ausgestaltung der Erfindung enthält das Bindemittel als v/eiteren Zusatz Diäthylenglykol.In an advantageous embodiment of the invention, the binder contains diethylene glycol as a further additive.

Die Erfindung wird nachstehend anhand eines Beispiels näher erläutert.The invention is explained in more detail below using an example.

Ein Dekorpapier mit einem Flächengewicht von 80 g/m und einem Titandioxydgehalt von ca. 30 Gew.% wird in einem Zweibadimprägnierwerk mit Kelaminharz imprägniert. Im Vorimp rägnierwerk sowie im Nachlackierwerk wird derselbe Harzansatz eingesetzt, der aus folgenden Komponenten besteht:A decorative paper with a basis weight of 80 g / m 2 and a titanium dioxide content of approx. 30% by weight is in one Two-bath impregnation unit impregnated with kelamin resin. in the The pre-impregnation unit and the post-coating unit are the same Resin approach used, which consists of the following components:

100 Gew.Teile einer ca. 60 Gew.%igen wässrigen100 parts by weight of an approximately 60% strength by weight aqueous

Melaminharzlösung 1,5 Gew.Teile Polyvinylalkohol
2 Gew.Teile DiäthylenglykolMelamine resin solution 1.5 parts by weight polyvinyl alcohol
2 parts by weight of diethylene glycol

0,6 Gew.Teile eines Härters, der aus dem Erdalkalisalz einer starken Säure besteht.0.6 parts by weight of a hardener consisting of the alkaline earth salt of a strong acid.

Das Papier wird in der Zweibadimprägniermaschine so imprägniert, daß das Halbfabrikat einen Harzauftrag von ca. 150 % (aufgetragenes Festharz bezogen auf Rohpapiergewicht) und einem volatilen Gehalt von ca. 60 % besitzt.The paper is impregnated in the two-bath impregnation machine in such a way that the semi-finished product has a resin application of approx. 150 % (applied solid resin based on the weight of the raw paper) and a volatile content of approx. 60%.

Das so imprägnierte in Form"einer Bahn vorliegende Dekorpapier wird nun, wie in der Beschreibung zum Hauptpatent näher erläutert, zusammen mit einer Vulkanfiberfolienbahn in der beheizten Bandpresse zu einem Dekorlaminat verpreßt.The decor paper thus impregnated in the form of "a web" is now, as explained in more detail in the description of the main patent, together with a vulcanized fiber film in the heated belt press pressed into a decorative laminate.

Das auf diese Weise erhaltene Dekorlaminat zeichnet sich durch eine besonders gute, geschlossene Oberfläche und eine hohe Wasserdampfunempfindlichkeit aus.The decorative laminate obtained in this way is characterized by a particularly good, closed surface and a high water vapor insensitivity.
