Abstract

Compared with conventional polyvinyl chloride films, polyolefin films offer advantages as furniture surface material, essentially consisting in the ability to be bonded using urea-formaldehyde resin glues. The invention relates to a process for enabling calendering by controlling the melt viscosity of the polyolefins to be calendered. For this purpose, certain organic or inorganic fillers in predominantly fibrous form, for example wood pulp or asbestos fibres, are suitable.

Description

In der Möbeqindustrie verarbeitet man flächigeIn the furniture industry, flat ones are processed

Oberflächenmaterialien nach im wesentlichen drei Verfahren: a) Holzfurniere und Folien auf Papierbasis auf Pressen unter Verwendung von Harnstoffharz-Formaldehyd-Leimen b) Folien auf PVC-Basis mit Dispersionsklebern c) Holzfurniere, Folien auf Papierbasis und PVC-Folien mit Schmelzklebstoffen Der Markt der Möbeloberflächen, die unter Verwendung von Harnstoffharz-Formaldehyd-Leimen erzeugt warden, ist PVC-Folien nicht zugängloch. Die erheblichen Vorteile kalandrierter Folien sind nicht nutzbar.There are essentially three methods of surface materials: a) Wood veneers and paper-based films on press using urea resin-formaldehyde sizes b) PVC-based foils with dispersion adhesives c) Wood veneers, paper-based foils and PVC films with hot melt adhesives The market of furniture surfaces, which under If urea resin-formaldehyde glues are used, PVC films are not access hole. The considerable advantages of calendered films cannot be used.

Es ist bekannt, daß Polyolefinfolien und polyolefinbeschichtete bahnenförmige Materialien leicht mit Harnstoffharz-Formaldehyd-Leimen ausreichend gut auf Holzsubstrate zu verkleben sind, wenn entweder einerseits bedingt durch Coronaentladung auf der Oberfläche beim Blasen und Extrudieren von Polyolefinfolten, andererseits beim Extrusionsbeschichten von z. B. Papierbahnen durch Luftsauerstoffeinwirkung auf die extrem heiße Schmelze die Polyolefinoberfläche oxidiert wird.It is known that polyolefin films and polyolefin-coated sheet-like Materials lightly with urea resin-formaldehyde glue sufficiently well on wood substrates are to be glued if either due to the corona discharge on the one hand Surface when blowing and extruding polyolefin films, on the other hand when extrusion coating from Z. B. Paper webs by exposure to atmospheric oxygen to the extreme hot melt the polyolefin surface is oxidized.

Durch Behandeln von Polyolefinoberflächen mit oxidierenden Flammen wird ebenfalls die Verklebbarkeit erzeugt.By treating polyolefin surfaces with oxidizing flames the bondability is also generated.

Diese Eigenschaft läßt im Laufe der Zeit nach.This property diminishes over time.

Durch Beschichtung der aktivierten Fläche - bei beidseitiger Behandlung Oberfläche und Folienrückseite - mit geeigneten handelsüblichen Primern gelingt eine gute Konservierung der Verklebeeigenschaften unter gleichzeitiger Nutzung der Primerschicht für einen Schichtaufbau.By coating the activated surface - with treatment on both sides Surface and back of film - succeed with suitable commercial primers a good preservation of the adhesive properties with simultaneous use of the Primer layer for a layer structure.

Es ist ebenso bekannt, daß kristalline Eanststoffe, bedingt durch den definierten Schmelzpunkt und infolge der rasch abfallenden Schmelzenviskosität beim Erhöhen der Temperatur, nicht im Kalanderverfahren verarbeitbar sind. Es liegen Erfahrungen vor, diesen Nachteil durch Beimischung von Legierungskunststoffen bei z. B. » Polyoxymethylen zu beseitigen. Ähnliche Effekte bei der Erhöhung der Schmelzenviskosität sind durch faserige Zusätze organischer und anorganischer Art erzielt worden. Zusatzmengen von 10 - 30 Volumenprozent ändern das Sigenschaftsbild der Polyolefinschmelzen so, daß ein einwandfreies Kalandrieren gegeben ist.It is also known that crystalline substances are caused by the defined melting point and due to the rapidly falling melt viscosity when increasing the temperature, cannot be processed in the calendering process. There are Experience has shown this disadvantage through the addition of alloy plastics z. B. »Eliminate polyoxymethylene. Similar effects when increasing the melt viscosity have been achieved through fibrous additives of an organic and inorganic nature. Additional quantities from 10 - 30 percent by volume change the characteristics of the polyolefin melts so that that perfect calendering is given.
