Abstract

A process for producing a pressed sheet which comprises at least a cured paper web impregnated with synthetic resin and has a structured surface, for the production of surface-structured high pressure laminate boards is characterised in that a metal coating is applied at least onto one structured surface.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Preßplatte mit strukturierter Oberfläche für die Herstel­ lung von oberflächenstrukturierten Hochdruck-Schichtpreß­ stoffplatten, bestehend aus mindestens einer ausgehärte­ ten, mit Kunstharz imprägnierten Papierbahn.The invention relates to a method for producing a Press plate with a structured surface for the manufacturer development of surface-structured high-pressure layer press fabric panels consisting of at least one hardened paper impregnated with synthetic resin.

Arbeitsplatten für den Küchenbereich, den sanitären Be­ reich usw. werden als Verbundplatten hergestellt, die aus einer Grundplatte, z. B. Spanplatte, und einer damit ver­ bundenen ggfls. ein Dekor und/oder eine bestimmte Ober­ flächenstruktur aufweisenden Deckplatte bestehen, die als Hochdruck-Schichtpreßstoffplatten bezeichnet werden.Worktops for the kitchen area, the sanitary be rich etc. are made as composite panels that are made from a base plate, e.g. B. chipboard, and one ver bound if necessary. a decor and / or a certain waiter  surface structure having cover plate, which as High pressure laminate sheets are called.

Bei der Herstellung derartiger Hochdruck-Schichtpreßstoff­ platten kommt der Oberflächengebung dieser Artikel eine große Bedeutung zu. In der Regel werden hierzu Preßbleche verwandt, deren glänzende, mattierte oder strukturierte Oberfläche sich in den Schichtpreßstoffplatten abprägt und somit für die Oberflächengebung der Schichtpreßstoffplat­ ten verantwortlich ist. Um während der Aushärtung der Schichtpreßstoffplatten ein Anhaften des Kunstharzes, ins­ besondere Melaminharzes, der Dekorseite an den Preßblechen zu verhindern, sind die Preßbleche in der Regel an der Oberfläche mit einer Chromschicht ausgestattet oder sie bestehen aus Chromstahl. Diese Bleche sind außerordentlich teuer, so daß als Alternative, insbesondere bei der Erwar­ tung kleinerer Seriengrößen, ein Fertigungsverfahren über sogenannte Matrizen entwickelt wurde. Diese Matrizen be­ stehen im Normalfall aus Kunststoff- bzw. kunststoffim­ prägnierten Papieren, die ähnlich wie Hochdruck-Schicht­ preßstoffplatten zuvor mit einem Strukturgeberblech ge­ prägt und dabei ausgehärtet werden. Der Kunststoffcharak­ ter dieser Matrizen macht es erforderlich, daß - um ein Anhaften des Schichtpreßstoffes an der Matrize zu vermei­ den - beim Preßvorgang zwischen Matrize und Schichtpreß­ stoff eine Trennlage angebracht wird, die beispielsweise aus einer Aluminium- und Polypropylenfolie bestehen kann. Diese Trennlage ist nur einmal zu verwenden, so daß die Produktionskosten bei Verwendung einer Matrize durch die zusätzliche Trennlage relativ hoch werden. Bei den beiden verschiedenen Verfahren hat somit das Preßblech den Vor­ teil geringerer Produktionskosten, aber hohe Beschaffungs­ kosten, die Matrize den Vorteil geringerer Beschaffungs-, aber höherer Produktionskosten.In the production of such high pressure laminate The surface finish of these articles is one great importance too. As a rule, press plates are used for this related, their shiny, matt or textured Surface is embossed in the laminate and thus for the surface of the laminate ten is responsible. To during the curing of the Laminated sheets an adhesion of the synthetic resin, ins special melamine resin, the decorative side on the press plates to prevent the press plates are usually on the Surface equipped with a chrome layer or she are made of chrome steel. These sheets are extraordinary expensive, so that as an alternative, especially with the Erwar processing smaller series sizes, a manufacturing process via so-called matrices was developed. These matrices be are usually made of plastic or plastic embossed papers that are similar to high pressure layer Prepressstoffplatten ge with a structure sheet shapes and be cured in the process. The plastic character ter of these matrices requires that - in order to Avoid adhesion of the laminate to the die den - during the pressing process between the die and the layer press a separating layer is attached, for example can consist of an aluminum and polypropylene film. This separation layer is to be used only once, so that the Production costs when using a die by the additional separation layer become relatively high. With the two different processes, the press plate has the front partly lower production costs, but high procurement cost, the die has the advantage of lower procurement, but higher production costs.

Der Erfindung liegt die Aufgabe zugrunde ein Verfahren zu schaffen, welches die Vorteile der beiden bekannten Ver­ fahren vereinigt.The invention is based on the object of a method  create, which the advantages of the two known Ver drive united.

Zur Lösung dieser Aufgabe ist das erfindungagemäße Verfah­ ren bzw. die erfindungsgemäße Preßplatte dadurch gekenn­ zeichnet, daß man ein- oder beidseitig eine Metallbe­ schichtung aufträgt, und zwar bevorzugt in Form einer Chrom- und Chrom-Nickel-Verbindung.To solve this problem is the inventive method ren or the press plate according to the invention thereby characterized records that one or both sides of a metal layering, preferably in the form of a Chrome and chrome-nickel compound.

Eine auf diese Weise hergestellte Preßplatte läßt sich bei der Herstellung von Hochdruck-Schichtpreßstoffplatten ohne Verwendung einer Trennlage einsetzen.A press plate produced in this way can be the production of high pressure laminate without Use a separating layer.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß beidseitig auf eine starre Trägerplatte, die vorzugsweise aus Aluminium oder Messing besteht, je­ weils mindestens eine mit Kunstharz imprägnierte Papier­ bahn aufgelegt wird, auf deren außen liegende Oberfläche die Metallbeschichtungen aufgetragen werden.According to a preferred embodiment of the invention provided that on both sides on a rigid support plate, which is preferably made of aluminum or brass, depending because at least one paper impregnated with synthetic resin web is placed on its outer surface the metal coatings are applied.

Das erfindungsgemäße Verfahren so wie die nach diesem Ver­ fahren hergestellte Preßplatte werden im folgenden anhand der Fig. 1 bis 4 beschrieben. DieThe method according to the invention as well as the press plate produced according to this method are described below with reference to FIGS . 1 to 4. The

Bei der Ausführungsform gemäß Fig. 1 sind beidseitig auf einer Trägerplatte 3, insbesondere aus Aluminium oder Messing, mit Kunstharz imprägnierte Papierbahnen 4 ange­ bracht, die an ihrer Außenseite mit jeweils einer Metall­ beschichtung 2 versehen sind. Die Trägerplatte 3 hat eine Dicke von etwa 2 bis 3 mm. Die Papierbahnlagen 4 können aus jeweils einer oder mehreren Schichten mit einer Dicke von 0,1 bis 0,25 mm bestehen, wobei es sich bei dem Kunst­ harz bevorzugt um Melamin- oder Phenolharze handelt. Die Metallbeschichtungen 2 bestehen aus einer Chromschicht oder einer Chrom-Nickel-Schicht.In the embodiment according to FIG. 1, paper webs 4 impregnated with synthetic resin are placed on both sides of a carrier plate 3 , in particular made of aluminum or brass, which are each provided with a metal coating 2 on their outside. The carrier plate 3 has a thickness of approximately 2 to 3 mm. The paper web layers 4 can each consist of one or more layers with a thickness of 0.1 to 0.25 mm, the synthetic resin preferably being melamine or phenolic resins. The metal coatings 2 consist of a chrome layer or a chrome-nickel layer.
