Description

Verfahren zum Vulkanisieren von aus Naturkautschuk, Butylkautschuk und Athylen-Terpolymer-Kautschuk bestehenden Verschnitten Die Erfindung bezieht sich auf ein Verfahren zum Vulkanisieren von aus Naturkautschuk, Butylkautschuk und Äthylen-Terpolymer Kautschuk bestehenden Verschnitten, die übliche Zusätze, insbesondere FUllstoffe, Weichmacher und Alterungsschutzmittel, enthalten, unter Druck und Wärme.Process for vulcanizing from natural rubber, butyl rubber and ethylene terpolymer rubber blends The invention relates refer to a process for vulcanizing natural rubber, butyl rubber and ethylene terpolymer rubber existing blends, the usual additives, in particular fillers, plasticizers and anti-aging agents, contain, under Pressure and heat.

Ungesättigte Polymere konnten bisher mit einem gesättigten Polymer nicht so zusammenvulkanisiert werden, daß ein praktisch verwendbares Vulkanisat entsteht. Seit der Erfindung des Butylkautschuks im Jahre 1937 blieben Bestrebungen, dieses Polymer gemeinsam mit normalen ungesättigten Polymeren zu verarbeiten, ohne wesentlichen Erfolg. Theoretisch war man wohl in der Lage, die Vulkanisierbarkeit von Butylkautschuk mit anderen Polymeren auszu£Uhren. Die praktischen Versuche hatten aber keinen Erfolg, d.h., die erzielten physikalischen Eigenschaften des Vulkanisates geneigten nicht den praktischen Anforderungen.Unsaturated polymers could previously with a saturated polymer are not vulcanized together so that a practically usable vulcanizate arises. Since the invention of butyl rubber in 1937, efforts have continued to to process this polymer together with normal unsaturated polymers without substantial success. Theoretically one was probably able to measure the vulcanizability from butyl rubber to other polymers from £ clocks. The practical trials had but no success, i.e. the achieved physical properties of the vulcanizate inclined not to the practical requirements.

Um den Butylkautschuk trotzdem allgemein verwendbar zu machen, wurden halogenierte Butylkautschuke entwickelt, die die Eigenschaften von Butylkautschuk mit der Verträlichkelt ungesättigter Polymere verbinden. Diese Entwicklung zeigt, daß das Problem, Butylkautschuk mit anderen Polymeren zu vulkanisieren, von der Fachwelt zumindest vorläufig als unlösbar angenommen wird.In order to make the butyl rubber generally usable nevertheless, were halogenated butyl rubbers developed that have the properties of butyl rubber connect with the compatibility of unsaturated polymers. This development shows that the problem of vulcanizing butyl rubber with other polymers from the Professional world is assumed to be unsolvable, at least for the time being.

Die Vor- und Nachteile der halogenierten Butylkautschuke sind bekannt. Der bromierte Butylkautschuk ist in seinen Eigenschaften günstiger als der chlorierte. Diese Kautschukverbindungen sind zwar verhältnismäßig teuer, jedoch billiger als Chloroprenkautschuk, chlorsulfoniertes Polyäthylen usw.The advantages and disadvantages of halogenated butyl rubbers are known. The properties of the brominated butyl rubber are more favorable than the chlorinated. These rubber compounds are relatively expensive, but cheaper than Chloroprene rubber, chlorosulfonated polyethylene, etc.

Luftschläuche aus Butylkautschuk werden für Fahrzeugbereifungen in bedeutendem Umfange hergestellt. Trotzdem wurde bis jetzt von keinem Hersteller z. B. das Problem nStoß" bei Butylkautschukschläuchen befriedigend gelöst. Als Grund dafür muß die durch den Polymercharakter bedingte schlechte Klebkraft und der kalte Fluß des Butylkautschuks angesehen werden.Butyl rubber air hoses are used for vehicle tires in made to a significant extent. Nevertheless, until now it has not been made by any manufacturer z. For example, the problem of "shock" in butyl rubber hoses has been satisfactorily solved this must be due to the poor bond strength due to the polymer character and the cold Butyl rubber flow.

Es wurde nun gefunden, daß diese Nachteile durch das Verschneiden von Butylkautschuk mit anderen Polymeren gesättigter und ungesättigter Art vermieden bzw. verkleinert werden können. Die Errindung ist dementsprechend dadurch gekennzeichnet, daß solche Verschnittmischungen vulkanisiert werden, die weniger als einen Gewichtsteil elementbren Schwefel, bezogen auf 100 Gewichtsteile Gesamtkautschuk, Dibenzothiazyldisulfid, Diphenylguanidin, Tetramethylthiuramdisulfid, Mercaptobenzothiazol, Phthal säureanhydri d und pp'-Dibenzoylchinondioxim als Vulkanisationssystem enthalten.It has now been found that these disadvantages are caused by the blending of butyl rubber with other polymers of a saturated and unsaturated type avoided or can be reduced in size. The invention is accordingly characterized by that such blends are vulcanized which are less than one part by weight elementary sulfur, based on 100 parts by weight of total rubber, dibenzothiazyl disulfide, Diphenylguanidine, tetramethylthiuram disulfide, mercaptobenzothiazole, phthalic anhydride d and pp'-dibenzoylquinone dioxime as a vulcanization system.
