Description

"nmroplastische Schiehtstoffplatte mit rückseitigem Le imauf trag It Leimauftrag" Duroplastische, insbesondere dekorative Schichtstoffe werden in der Regel auf Trägermaterialien verleimt, wie z. B. Spanplatten, Hartfaserplatten, Sperrholz u. ä. Die Verleimungsmethoden hängen dabei ab von der Art der verwendeten Leime, d. h. man muß z. B. den Leim ein-oder beidseitig aufgeben, bei höherer oder niederer Temperatur arbeiten, mit größerem oder kleinerem Druck und mit mehr oder weniger langer Preßzeit. Der Verarbeiter ist also an bestimmte Bedingungen gebunden, die den Durchsatz in seiner Fertigung maßgeblich beeinflussen. Insbesondere gilt das auch von den Zeiten, die zwischen dem Auftragen des Leimes und der Verpressung mit dem Trägermaterial mindestens verstreichen müssen bzw. höchstens verstreichen dürfen. "Neoplastic plastic sheet with back Le imauf order It Glue application " Duroplastic, especially decorative laminates are usually glued to carrier materials, such as. B. chipboard, hardboard, plywood and the like. The gluing methods depend on the type of glue used, ie you have to z. B. give up the glue on one or both sides, work at a higher or lower temperature, with higher or lower pressure and with a more or less long pressing time. The processor is therefore bound to certain conditions that have a decisive influence on the throughput in his production. In particular, this also applies to the times that must or may at most pass between the application of the glue and the pressing with the carrier material.

In dieser Beziehung vor allem würden Schichtstoffe, die'den erforderlichen Leim auf der Rückseite bereits bei der Anlieferung, vom Hersteller her, enthalten, besondere Vorteile bieten. Diese Vorteile wären z. B. darin zu sehen, daß beim Hersteller mit größerer Kontinuität gearbeitet werden kann, d. h. rationeller und gleichmäßiger, und daß der Verarbeiter die zum Verpressen mit dem Trägermaterial bestimmten Platten zu jedem beliebigen Zeitpunkt seinem Lager entnehmen und sofort einsetzen kann.In this regard, laminates in particular would be required Glue on the back already included in the delivery from the manufacturer, offer special advantages. These advantages would be e.g. B. can be seen in the fact that the manufacturer can be operated with greater continuity, d. H. more rational and more even, and that the processor prepares the plates intended for pressing with the carrier material can be taken from its warehouse at any time and used immediately.

Es hat sich nun gezeigt, daß man diese Vorteile erreichen kann, wenn man die Rückseite der Schichtstoffplatte mit einer dünnen Schicht eines Leimes versieht, der bei normaler Temperatur nicht klebt, eine sehr große Klebkraft jedoch entfaltet, wenn er zusammen mit dem Trägermaterial unter mäßigen Drucken auf höhere Temperatur gebracht wird. Als Leim eignen sich insbesondere handelsübliche Heißsiegelkleber. : Mit solchen Klebern können in normalen Furnierpressen bei Drucken von 3-8 kg/cm2 und kurzem Aufheizen auf etwa 80°C mit sofort anschließender Rückkühlung ausgezeichnete Haftfestigkeiten erzielt werden.It has now been shown that these advantages can be achieved if the back of the laminate board is provided with a thin layer of glue, which does not stick at normal temperature, but develops a very high adhesive strength, when it is together with the carrier material under moderate pressure at a higher temperature is brought. Commercially available hot-seal adhesives are particularly suitable as glue. : Such adhesives can be used in normal veneer presses at pressures of 3-8 kg / cm2 and Short heating to about 80 ° C with immediate subsequent cooling is excellent Adhesion strengths can be achieved.

Dekorative Plattenmateria'lien mit rückseitigem Leimauftrag sind zwar als solche bereits bekannt, jedoch handelt es sich hierbei um thermoplastische Materialien mit rückseitigen Kontaktklebern. Bei duroplastischaaSchiehtstoffen im Sinne dieser Anmeldung fahren Kontaktkleber jedoch nicht zu dem gewünschen Ergebnis, da sie nicht die notwendige Haftfestigkeit haben, um ein Abspringen der harten Schichtstoffplatte von dem Trägermaterial mit Sicherheit zu verhindern.Decorative panel materials with glue on the back are admittedly already known as such, but these are thermoplastic materials with contact adhesive on the back. In the case of thermosetting foils in the sense of this Registration drive contact adhesives however not to the desired result, since they do not have the necessary adhesive strength to prevent the hard laminate board from cracking off to prevent from the carrier material with certainty.

In der Zeichnung ist der Aufbau der Schichtstoffplatte (ohne Trägermaterial) aus Kern, Dekorschicht und Uberpresserfolie einerseits und der erst bei höherer Temperatur klebefähigen Leimschicht andererseits schematisch dargestellt.The drawing shows the structure of the laminate board (without carrier material) made of core, decorative layer and press-on foil on the one hand, and only with a higher one Temperature adhesive layer of glue on the other hand shown schematically.

Schutzanspruch ----------------
Duroplastische, insbesondere dekorative Schichtstoffplatte, dadurch gekennzeichnet, daß die Platte auf ihrer Rückseite mit einer bei normaler Temperatur nicht klebenden, aber bei erhöhter Temperatur klebfähigen Leimschicht, z. B. aus einem handelsüblichen Heißsiegelkleber versehen ist.
Claim to protection ----------------
Duroplastic, in particular decorative laminate board, characterized in that the board is coated on its back with a layer of glue which is non-adhesive at normal temperature but which is adhesive at elevated temperature, e.g. B. is provided from a commercially available heat seal adhesive.
