Description

Elastomere Dichtungen für eine Aerosoi-Konditionierung, die Dimethylather enthält.Elastomer seals for an Aerosoi conditioning, which contains dimethyl ether.

Die vorliegende Erfindung betrifft elastomere Dichtungen für eine Aerosol-Konditionierung oder Zubereitung und bezieht sich insbesondere auf derartige Dichtungen, die für Zubereitungen Verwendung finden, die Dimethyläther enthalten .The present invention relates to elastomeric seals for aerosol conditioning or formulation and relates to in particular on such seals that are used for preparations that contain dimethyl ether .

Bei derartigen Aerosol-Konditionierungen, die Dimethyläther und Wasser enthalten, läuft eine Reaktion an der inneren Dichtung entsprechend dem Verlauf der Extraktion ab, die sich in einer Wandkorrosion (corrosion des parois) des Aerosolbehälters äußert.In such aerosol conditioning, the dimethyl ether and contain water, a reaction takes place at the inner seal according to the course of the extraction in a wall corrosion (corrosion des parois) des Aerosol container expresses.

Der Dimethyläther extrahiert aus der Dichtung sulfurierte und chlorierte Verbindungen, die, gelöst in Wasser, das Metall der Kapsel (coupeile) und möglicherweise das Metall des Behälters angreift. Dieser Angriff zeigt sich insbesondere im Kontaktbereich der inneren Dichtung mit O der Ventilkapsel (coupeile de la valve), im allgemeinen rühren die sulfurierten Verbindungen von den Vulkanisationsmitteln her, während die chlorierten Verbindungen einen integrierten Bestandteil des Elastomeren, beispielsweise des Chloroprens, ausmachen.The dimethyl ether extracted from the seal sulphurized and chlorinated compounds which, when dissolved in water, the metal of the capsule (coupeile) and possibly that Attacks the metal of the container. This attack is particularly evident in the contact area of the inner seal O the valve capsule (coupeile de la valve), in general stir the sulfurized compounds from the vulcanizing agents, while the chlorinated compounds make up an integral part of the elastomer, for example chloroprene.

Man hat schon versucht, die freien Chlorionen mit einem Überschuß an Magnesiumoxid zu neutralisieren und die üblicherweise sulfurierten Vulkanisationsmittel durch schwefelfreie Verbindungen zu ersetzen.Attempts have already been made to neutralize the free chlorine ions with an excess of magnesium oxide, and those usually sulfurized vulcanizing agents by sulfur-free ones Replace connections.

Diese bekannten Lösungsvorschläge begrenzen jedoch den Extraktionsgrad des DimethyJäthers, ohne ihn jedoch ganz zu verhindern oder wenigntonB in einer wirksamen Art und Weise zu unterdrücken.However, these known proposed solutions limit the degree of extraction of the dimethyl ether, but without it completely to prevent or reduce tone in an effective manner and Way to suppress.

Ein anderer Nachteil der Konditionierungen mit Dimethylähter besteht darin, daß sie verhältnismäßig beträchtliche Gewichtsverluste der Aerosole hervorrufen, die infolge einer Diffusion der Dämpfe des Dimethylathers quer durch die üblicherweise verwendeten inneren Dichtungen ) bedingt sind.Another disadvantage of conditioning with dimethyl stitching is that they are relatively sizeable Cause weight loss of the aerosols, which as a result a diffusion of the vapors of the dimethyl ether across due to the inner seals usually used).

Die vorliegende Erfindung hat zum Ziel, eine Dichtungszusammensetzung zur Verfugung zu stellen, die gegenüber den Konditionierungen mit Dimethy1äther und Lösungsmitteln, wie z. B. Wasser, Chlormethylen, Kohlenwasserstoffen, widerstandsfähig ist und die darüber hinaus einen gegenüber dem Dimethyläther sehr schwachen Extraktionskoeffizienten und einen Permeabilitätskoeffizienten aufweist, der merklich geringer ist, als bei den üblicherweise bei Aerosol-Konditionierungen verwendeten Dichtungen.The present invention aims to provide a sealing composition to make available, in contrast to the conditioning with dimethyl ether and solvents, such as B. water, chloromethylene, hydrocarbons, resistant and which, moreover, has a very weak extraction coefficient compared to dimethyl ether and has a coefficient of permeability which is significantly lower than that commonly used in aerosol conditioning used seals.

Die vorliegende Erfindung stellt elastomere Dichtungen für eine Aerosol-Konditionierung zur Verfugung, die wenigstens 1 Lösungsmittel der Gruppe von Verbindungen, die Wasser, Chlormethylen, Butan, Propan umfaßt, und ein verdampfbares Treibmittel enthält, die wenigstens teilweise aus Dimethyläther besteht.The present invention provides elastomeric seals for aerosol conditioning that at least 1 Solvent of the group of compounds including water, chloromethylene, butane, propane, and a vaporizable one Contains propellant, which consists at least partially of dimethyl ether.

Die Erfindung zeichnet sich dadurch aus, daß diese elastomeren Dichtungen wenigstens teilweise aus einem modifizierten oder nichtmodifizierten Buty IeI astomeren bestehen, der mit einem schwefelfreien Oxidationsmittel in Abwesenheit von freiem Chlor vulkanisiert ist.The invention is characterized in that these elastomeric Seals consist at least partially of a modified or unmodified Buty IeI astomer, the with a sulfur-free oxidizing agent in the absence is vulcanized by free chlorine.

Diese Dichtungen können wenigstens zum TeiJ aus einem Butylisoprencopolymereη bestehen.These seals can at least in part consist of a butyl isoprene copolymer.

• Darüber hinaus können diese Dichtungen wenigstens zum Teil
eine Substanz der Gruppe ent.haJt.en, die Zinkoxid, Stearinsäure, Carbon-Black, Kaolin, Paraffin, phenolische Harze,
Phenol-Formaldehydharze, Zirikdiäthylthiocarbamat, Polyäthylen, Styrol-Butadien oder Chlorbutyl umfaßt.• In addition, these seals can at least partially
a substance belonging to the group containing zinc oxide, stearic acid, carbon black, kaolin, paraffin, phenolic resins,
Phenol-formaldehyde resins, Zirikdiäthylthiocarbamat, polyethylene, styrene-butadiene or chlorobutyl includes.

Diese elastomeren Dichtungen können gleichfalls, wenigstens teilweise aus einem Hutylchiorisoprencopolymeren bestehen
und Magnesiumoxid in einer Menge enthalten, die zumindestens gleich derjenigen Menge ist, die für die Neutralisation des freisetzbaren Chlors vonnöten ist, das in der Dichtung enthalten ist.These elastomeric seals can also consist at least partially of a Hutylchiorisoprencopolymeren
and contain magnesium oxide in an amount at least equal to the amount required to neutralize the releasable chlorine contained in the seal.

Die mechanischen Eigenschaften des Elastomeren auf Basis von Butylkautschuk werden mittels der Copolymerisation mit Isopren oder Chlorisopren verstärkt. Diese Copolymerisation vermindert merklich die Reaktivität des freien Chlors im Fall der Zugabe von Chlorisopren. Außerdem gestattet die weitere Zugabe von Magnesiumoxid, zusätzlich zu der vulkanisierenden Aktivität, den Chlorüberschuß zu neutralisieren.The mechanical properties of the elastomer based on Butyl rubber is reinforced by means of copolymerization with isoprene or chloroisoprene. This copolymerization diminishes noticeably the reactivity of the free chlorine in the case of the addition of chloroisoprene. It also allows further addition of magnesium oxide, in addition to the vulcanizing activity, to neutralize the excess chlorine.

Die Permeabilität der solchermaßen modifizierten Kautschukarten ist sehr schwach, was ihre Verwendung bei den Hüllen
von Druckluftschläuchen rechtfertigt (enveloppes de chambres ä air de pneumatiques) .The permeability of the types of rubber modified in this way is very weak, which makes their use in the case of the casings
of compressed air hoses (enveloppes de chambres a air de pneumatiques).

Die erfindungsgemäßen elastomeren Dichtungen machen es möglich, Ventile zu verwirklichen, deren metallische Abstützung oder Kapsel (support metallique ou coupelle), die am Hals des Behälters angeordnet ist, keinen Schutz durch einen Anstrich oder einen Lack benötigt, der sich von denjenigen! unterscheidet, der infolge der Aggressivität der zu verteilenden Produkte
Verwendung findet.The elastomeric seals according to the invention make it possible to realize valves whose metallic support or capsule (support metallique ou coupelle), which is arranged on the neck of the container, does not require protection by a paint or varnish that differs from those! differs due to the aggressiveness of the products to be distributed
Is used.

Die Erfindung wird anhand der nachfolgenden Beschreibung noch deutlicher, die mehrere Ausführungsarten beinhaltet, die jedoch ihrerseits die Erfindung nicht einschränken.The invention will be based on the following description even clearer, which includes several types of execution, however, these in turn do not limit the invention.

Um nun Dichtungen für Aerosol-VentiIe zu verwirklichen, die chlor- und schwefelfrei sind und die für die Konditionierung in Dimethylather einsetzbar sind, stellt man gemäß der Erfindung eine Elastomerenmischung her, die 100 Gewichtsteile Butyleiastomeren, l,b Gewichtsteile Stearinsäure, 5 Gewichtsteile Zinkoxid, 50 Gewichtsteile Carbon-Black, 10 Gewichtsteile kalziniertes Caolin, 7,5 Gewichtsteile Paraffinöl und 7 Gewichtsteile wirksames Phenolharz enthält.In order to realize seals for aerosol valves that which are free of chlorine and sulfur and which can be used for conditioning in dimethyl ether are produced according to the invention an elastomer mixture, the 100 parts by weight Butyl elastomers, l, b parts by weight of stearic acid, 5 parts by weight of zinc oxide, 50 parts by weight of carbon black, 10 parts by weight contains calcined caolin, 7.5 parts by weight of paraffin oil and 7 parts by weight of active phenolic resin.
