Description

Verbundfolie für Beschichtungszwecke, insbesondere für den Korrosionsschutz Die Erfindung betrifft in einem Arbeitsgang vorgefertigte vulkanisierte Verbundfolien für Beschichtungszwecke, insbesondere zum Auskleiden von gegen Korrosion zu schüt3enden Behältern.Composite film for coating purposes, in particular for corrosion protection The invention relates to prefabricated vulcanized composite films in one operation for coating purposes, in particular for lining those to be protected against corrosion Containers.

In einem Arbeitsgang vorgefertigte vulkanisierte Verbundfolien sind für die Verwendung im Saureschutzbau erstrebenswert zur Auskleidung von Behaltern mit nur schwer oder überhaupt nicht auf die Unterlage aufklebbaren Folien mit hinreichender chemiscner Beständigkeit in einem Arbeitsgang. Unterfolie und Beschichtungafolie sollen erfindungsgemäß im un vulkanisierten Zustand zusammenkalandriert und vulkanisiert werden.Vulcanized composite foils are prefabricated in one operation For use in acid protection structures, desirable for lining containers with films that are difficult or impossible to stick to the substrate with sufficient chemical resistance in one operation. Bottom film and coating film are to be calendered and vulcanized according to the invention in the un vulcanized state will.

Nach dem Gebrauchsmuster 1 933 834 wird die Verwendung vorgefertiger vulkanisierter isobutylkautschukfolien für Beschichtungszwecke, insbesondere für den Korrosionsschutz, ers-tmals möglich durch Verbund mit einer nichtvulkanisierten Folie aus Naturkautschuk, modifiziertem Naturkautschuk, synthetischen Kautschuksorten, z.B. auch aus nichtvulkanisiertem Isobutylkautschnuk, auf der Unterseite als Haftvermittler zur Unterlage.After the utility model 1 933 834, the use is more prefabricated vulcanized isobutyl rubber films for coating purposes, in particular for the corrosion protection, possible for the first time by bonding with a non-vulcanized one Foil made of natural rubber, modified natural rubber, synthetic rubbers, e.g. also made of non-vulcanized isobutyl rubber, on the underside as an adhesion promoter to the document.

Die nichtvulkanisierte Unterfolie vermittelt dabel einerseits eine gute Haftung auf der Unterlage und andererseits zur vorgefertigten vulkanisierten Isobutylkautschukfolie. Chemische Beanspruchung und/oder mechanische Beanspruchung kann unmittelbar nach der Beschichtung erfolgen.On the one hand, the non-vulcanized lower film conveys a good adhesion to the substrate and on the other hand to the prefabricated vulcanized Isobutyl rubber film. Chemical and / or mechanical stress can be done immediately after coating.

Schließlich hat das Setrauchsmuster 7 007 361 eine V@rbundfolie für Beschichtungszwecke mit ausvulkanisierter Unterfolie, insbesondere für den Korrosionsschutz, zum Gegenstand, bestehend aus einer vulkanisierten Isobutylkautschukfolie und einer auf? einer Seite aufvulkanisierten ausvulkani@@erten Folie aus synthetischen Kaut@chuksorten, modifiziertem Naturkautschuk oder Mischvulkanisaten aus synthetischen Kautschuksorten und Naturkautschuk.Finally, the set smoking pattern 7 007 361 has a wrap film for Coating purposes with fully vulcanized bottom film, especially for corrosion protection, to the subject, consisting of a vulcanized isobutyl rubber sheet and a on? one side vulcanized from vulcanized film made of synthetic rubber types, modified natural rubber or mixed vulcanizates made from synthetic rubbers and natural rubber.

Gegenstand der neuen Erfindung ist eine Verbundfolie zum i3'-schichten und Auskleiden von Behältern, ins@esondere von wegen Korrosion zu schützenden Behältern, bestehend aus einer vorvulkanisierten Unterfolie der Bindemittel-Zusammensetzung 40-60 Gewichtsteile Chloroprenkautschuk, 20-40 Gewichtsteile Gis-1,4-Polyisopren und 10-25 Gevichtsteile Chlorbutylkautschuk und einer darauf aufvulkanisierten Folie mit hoher chemischer Beständigkeit aus isobutylkautschuk, chlorsulfoniertem Polyäthylen, Polychlorbutadien, Mischpolymerisaten aus Butadien und Acrylnitril, Hexafluorpropylen-Vinylidenf@uorid-Mischpolymerisaten, Cis-1 ,4-Polyisopren. Butadien-Polymerisaten, Styrol-Butadien-Mischpolymerisaten oder dergleichen.The subject of the new invention is a composite film for i3'-layering and lining of containers, in particular of containers to be protected due to corrosion, consisting of a pre-vulcanized lower film of the binder composition 40-60 parts by weight of chloroprene rubber, 20-40 parts by weight of Gis-1,4-polyisoprene and 10-25 parts by weight of chlorobutyl rubber and a film vulcanized onto it with high chemical resistance made of isobutyl rubber, chlorosulfonated polyethylene, Polychlorobutadiene, copolymers of butadiene and acrylonitrile, hexafluoropropylene-vinylidene fluoride copolymers, Cis-1,4-polyisoprene. Butadiene polymers, styrene-butadiene copolymers or similar.

Der Vorteil der neuen Verbundfolie ist deren Aufklebbarkeit auf Stahl und Beton für unbegrenzte Zeit, ohne daß eine Nachvulkanisation der Oberfolie erforderlich wird.The advantage of the new composite film is that it can be stuck onto steel and concrete for an unlimited period of time without the need for post-vulcanization of the top sheet will.

Beispielsweise hat sich eine Verbundfolie mit einer Un-terfolie der Bindemittel-Zusammensetzung 50 % Polychlorbutadien, 33 % Cis-1,4-Polyisopren und 17 % Chlorbutylkautschuk sehr bewährt.For example, a composite film with a sub-film of Binder composition 50% polychlorobutadiene, 33% cis-1,4-polyisoprene and 17% chlorobutyl rubber has proven its worth.

Die Untereolie hat auch noch bei Temperaturen von 60°C und darüber eine hohe mechanische Festigkeit und eine sehr gute Haftung auf Stahl. Auch die Haftung zwischen der Unterfolie und der Oberfolie genügt allen Ansprüchen.The lower foil still has temperatures of 60 ° C and above high mechanical strength and very good adhesion to steel. Also the Adhesion between the lower film and the upper film meets all requirements.
