Abstract

A bonding adhesive is used in the mfr. of elastomer-film composites, esp. elastomer-polyvinylidene fluoride film or elastomer-polyvinyl fluoride composites. Pref. bonding adhesives are comprised of an elastomer mixt. of 10-70 wt.% polyoctenylene, 85-20 wt.% chloroprene and 5-10 wt.% chlorosulphonated polyethylene in a solvent mixt. of 10-90 wt.% aromatic solvents, 20-7 wt.% esters and 70-3 wt.% aliphatic solvents, with a rubber solids:solvent ratio in the adhesive of 1:1 to 1:1.5. USE/ADVANTAGE - The elastomer-film composites are useful as protective materials and in the prodn. of protective clothing for civil and military applications, esp. as a replacement for conventional rubberised fabric, with which the elastomer-film composites have a comparable performance whilst being cheaper and lighter in wt. so that the composite materials are less tiring to wear.

Description

Gummierte Gewebe werden als Schutzstoffe zivil und militärisch eingesetzt. Für besonders hohe Anforderungen sind teure Spezialkautschuk-Typen (z. B. Viton; Warenzeichen der Firma DuPont) und/oder hohe Gewichte erforderlich. Dies bedingt schwere Anzüge mit hoher Belastung für den Träger.Rubberized fabrics are considered civilian and protective used militarily. For particularly high requirements are expensive special rubber types (eg Viton; the company DuPont) and / or high weights required. This requires heavy suits with high load for the wearer.

Die Aufgabe der Erfindung besteht nun darin, durch Einsatz von Folien, insbesondere auf Basis von Polyvinylidenfluorid (PVDF) oder Polyvinylfluorid (PVF), bei gleichbleibender Schutzwirkung eine Gewichtseinsparung zu erzielen.The object of the invention is now, by use of films, in particular based on polyvinylidene fluoride (PVDF) or polyvinyl fluoride (PVF), with the same Protective effect to achieve a weight saving.

Gelöst wird diese Aufgabe durch den Einsatz von Haftpasten, insbesondere in Verbindung mit einem der Ansprüche 2 bis 6.This problem is solved by the use of adhesive pastes, in particular in conjunction with one of claims 2 to 6.

Von besonderer Bedeutung ist der Einsatz von Haftpasten auf der Basis von Polyoctenylen und/oder Chloropren (CR) und/oder von chlorsulfoniertem Polyethylen (CSM), wobei folgende Mischungszusammensetzung (in Gew.-%), und zwar bezogen auf die Gesamtmasse an Kautschuk, zweckmäßig ist:Of particular importance is the use of adhesive pastes on the basis of polyoctenylene and / or chloroprene (CR) and / or chlorosulfonated polyethylene (CSM), wherein the following mixture composition (in wt .-%), namely based on the total mass of rubber, it is expedient:

Polyoctenylenpolyoctenylene 10-7010-70 CRCR 85-2085-20 CSMCSM 5-105-10

Übliche Zuschlagstoffe sind Kieselsäure (5-18 Gew.-%), Klebharze (10-40 Gew.-%), Beschleuniger (1-4 Gew.-%) und sonstige Hilfsmittel (z. B. Farbstoffe), wobei sich hier die Mengenangaben auf die Gesamtmasse an Zuschlagstoffen beziehen. Typical additives are silica (5-18% by weight), Adhesive resins (10-40% by weight), accelerator (1-4% by weight) and other auxiliaries (eg dyes), wherein here the quantities on the total mass of aggregates Respectively.  

Die Haftpasten werden in einem Gemisch aus Aromaten, Ester und Aliphaten gelöst, wobei insbesondere folgende Lösungsmittelzusammensetzung (in Gew.-%) zum Einsatz kommt:The adhesive pastes are in a mixture of aromatics, esters and aliphatics, in particular the following Solvent composition (in wt .-%) used comes:

Aromaten (z. B. Toluol)Aromatics (eg toluene) 10-9010-90 Ester (z. B. Ethylacetat)Esters (eg ethyl acetate) 20-720-7 Aliphaten (z. B. Benzin mit dem Siedebereich +80 bis +110°CAliphatic compounds (eg gasoline with the boiling range +80 to + 110 ° C 70-370-3

Das Verhältnis von Feststoff zu Lösungsmittel beträgt zweckmäßigerweise 1 : 1 bis 1 : 1,5.The ratio of solid to solvent is suitably 1: 1 to 1: 1.5.

Darüber hinaus besteht die Aufgabe darin, ein geeignetes Verfahren zur Herstellung des Elastomer-Folien-Verbundes bereitzustellen.In addition, the task is to provide a suitable Process for producing the elastomer-film composite provide.

Gelöst wird diese Zusatzaufgabe durch folgende Verfahrensschritte:This additional task is solved by the following Steps:

  • - Die Lösung wird im Streichverfahren aufgetragen und getrocknet;- The solution is applied by brushing and dried;
  • - Zusammenfügen des Elastomers (gummiertes Gewebe) und der Folie mittels eines beheizbaren Doublierkalanders unter Druck (Temperatur: 50 bis 70°C; 1,5 t);- Assembly of the elastomer (rubberized fabric) and the film by means of a heated Doubling calender under pressure (Temperature: 50 to 70 ° C, 1.5 t);
  • - Vulkanisation unter Druck bei einer Temperatur, die unterhalb der Schmelztemperatur der Folie (überwiegend 150 bis 170°C) liegt.- Vulcanization under pressure at a temperature that below the melting temperature of the film (predominantly 150 to 170 ° C) is located.
