A seal for an aerosol prepn. contg. water, methylene chloride, butane and/or propane as solvent, consists at least partly of an (un)modified butyl elastomer which has been vulcanised with a S-free oxidisng agent in absence of free Cl. The sealant esp. consists (partly) of a butyl-isoprene copolymer opt. contg. ZnO, stearic acid, C black, kaolin, paraffin, phenolic resins, phenol-HCHo resins, Zn diethyldithiocarbamate, polyethylene, styrene-butadiene and/or chlorobutyl, or a butyl-chloroisoprene copolymer contg. MgO in amt. at least sufficient to neutralise Cl which may be liberated in the seal. The claimed sealant is a vulcanised mixt. of 100 pts. wt. butyl elastomer, 1.5 pts. stearic acid, 5 pts. ZnO, 50 pts. C black, 10 pts. calcined kaolin, 7.5 pts. paraffin oil, and 7 pts. phenol resin. The sealant resista dimethyl ether + a solvent, has a very low extn. coefft. w.r.t. diemthyl ether, and has a lower permeability coefft. to dimethyl ether than the usual sealants. The metal part or cap of the container does not need a protective lacquer.

Description

Joints élastomères pour conditionnement aérosol au diméthyléther.Elastomeric seals for aerosol packaging with dimethyl ether.

La présente invention concerne les joints élastomè- res pour conditionnement aérosol et vise plus particulière- ment les joints utilisés pour les conditionnements renfèr- mant du diméthyléther. The present invention relates to elastomeric seals for aerosol packaging and more specifically relates to seals used for packaging containing dimethyl ether.

Dans les conditionnements aérosol renfermant du diméthyléther et de l'eau, il se produit une réaction sur le joint interne selon un processus d'extraction qui se traduit par une corrosion des parois du récipient aérosol. In aerosol packages containing dimethyl ether and water, a reaction occurs on the inner seal according to an extraction process which results in corrosion of the walls of the aerosol container.

Le diméthyléther extrait du joint les composés sulfurés et chlorés qui, mis en solution dans l'eau, attaquent le métal de la coupelle et, éventuellement, du récipient. Cette attaque se manifeste plus particulièrement au niveau du contact du joint interne de la coupelle de la valve. Les composés sulfurés proviennent généralement des agents vulcanisants, tandis que les composés chlorés font partie intégrantedel'éîastomère, par exemple le chloro prène.  The dimethyl ether extracts from the joint the sulfur and chlorine compounds which, dissolved in water, attack the metal of the cup and, possibly, of the container. This attack manifests itself more particularly at the level of the contact of the internal seal of the valve cup. The sulfur compounds generally come from vulcanizing agents, while the chlorinated compounds are an integral part of the elastomer, for example chloro prene.

On a déjà essayé de neutraliser les ions chlores libres avec un excès de magnésie et de remplacer les agents vulcanisants sulfurés traditionnels par des composés dépourvus de soufre. Ces solutions classiques limitent le taux d'extraction du diméthyléther sans toutefois l'empêcher totalement, ou du moins de façon efficace. Attempts have already been made to neutralize the free chlorine ions with an excess of magnesia and to replace the traditional sulphurizing vulcanizing agents by sulfur-free compounds. These conventional solutions limit the extraction rate of dimethyl ether without, however, totally, or at least effectively preventing it.

Un autre inconvénient des conditionnements au diméthyléther est de provoquer des pertes de poids relativement importantes des aérosols conditionnés par suite d'une diffusion des vapeurs de diméthyléther au travers des joints internes classiques. Another drawback of dimethyl ether packaging is that it causes relatively large weight losses in the aerosols packaged as a result of diffusion of the dimethyl ether vapors through conventional internal seals.

L'invention -a pour but un joint résistant vis-a- vis des conditionnements renfermant du diméthyléther et des solvants, tels que l'eau, le chlorure de méthylène, les hydrocarbures et qui présente, en plus, un coef cient d'extraction très faible vis- -vis du diéthyléther et un coefficient de perméabilité sensiblement moindre que les joints traditionnellement utilisés dans les conditionnements aérosols.  The object of the invention is to provide a resistant seal with respect to packaging containing dimethyl ether and solvents, such as water, methylene chloride, hydrocarbons and which additionally has an extraction coefficient. very low vis-à-vis the diethyl ether and a coefficient of permeability significantly lower than the seals traditionally used in aerosol packaging.

L'invention a pour objet des joints élastomères pour conditionnement aérosol renfermant au moins un solvant du groupe comprenant l'eau, le chlorure de méthylene, le butane, le propane et un propulseur gazéifiable constitué au moins en partie par du diméthyléther, caractérisé en ce qu'ils sont constitués au moins en partie par un élastomère butyle modifié ou non, vulcanisé par un oxydant non soufré en l'absence de chlore libre. The invention relates to elastomeric seals for aerosol packaging containing at least one solvent from the group comprising water, methylene chloride, butane, propane and a gasifiable propellant constituted at least in part by dimethyl ether, characterized in that that they consist at least in part of a modified or unmodified butyl elastomer, vulcanized by an unsulfurized oxidant in the absence of free chlorine.

Ces joints peuvent etre constitués, au moins en partie, par un copolymère de butyle et d'isoprène. These seals can be formed, at least in part, by a copolymer of butyl and isoprene.

Ces joints peuvent renfermer au moins une substance du groupe comprenant l'oxyde de zinc, l'acide stéarique, le carbon black, le kaolin, la paraffine, les résines phénoliques et phénol-formol, le diéthyldithiocarbamate de zinc, le polyéthylène, le styrène-butadiène, le chlorobutyle. These seals may contain at least one substance from the group comprising zinc oxide, stearic acid, carbon black, kaolin, paraffin, phenolic and phenol-formaldehyde resins, zinc diethyldithiocarbamate, polyethylene, styrene -butadiene, chlorobutyl.

Ils peuvent également être constitués,au moins en partie, par un copolymère de butyle et de chloroisoprène, et renfermer de lamagnésie en quantité au moins égale a celle nécessaire à la neutralisation du chlore libérable contenu dans le joint. They can also consist, at least in part, of a copolymer of butyl and chloroisoprene, and contain magnesia in an amount at least equal to that necessary for the neutralization of the releasable chlorine contained in the joint.

Les propriétés mécaniques de l1élastomère de base de caoutchouc-butyle sont renforcées par copolymérisation avec l'isoprène ou le chloroisoprène. Cette copolymérisa- tion diminue sensiblement la réactivité du chlore libre dans le cas d'adjonction de chloroisoprène. L'addition complémentaire de magnésie permet d'ailleurs, en plus de l'activité vulcanisante, de neutraliser l'excès de chlore. The mechanical properties of the rubber-butyl base elastomer are enhanced by copolymerization with isoprene or chloroisoprene. This copolymerization significantly reduces the reactivity of free chlorine in the case of the addition of chloroisoprene. The additional addition of magnesia also makes it possible, in addition to the vulcanizing activity, to neutralize the excess of chlorine.

La perméabilité des caoutchoucs butyle ainsi modifiée est très faible, ce qui a justifié leur utilisa-tion dans les enveloppes de chambres a air de pneumatiques. The permeability of the butyl rubbers thus modified is very low, which justified their use in the casings of air chambers of tires.

Les joints élastomères suivant l'invention permettent de réaliser des valves dont le support métallique ou coupelle adapté sur le col du récipient ne nécessite aucune protection par vernis ou laque différente de celle utilisée suivant l'agressivité des produits a distribuer. The elastomeric seals according to the invention make it possible to produce valves whose metallic support or cup adapted on the neck of the container does not require any protection by varnish or lacquer different from that used according to the aggressiveness of the products to be distributed.

L'invention sera mieux comprise a la lecture de la description qui va suivre de plusieurs modes de réalisation non limitatifs de l'invention.  The invention will be better understood on reading the following description of several non-limiting embodiments of the invention.

Pour réaliser des joints pour valves aérosol exernpts de chlore libre et de soufre utilisables pour le conditionnement au diméthyléther, suivant l'invention, on préparera un mélange d'élastomères renfermant pondéralement 100 parties d'élastomère butyle, 1,5 partie d'acide stéarique, 5 parties d'oxyde de zinc, 50 parties de carbon black, 10 parties de kaolin calciné, 7,5 parties d'huile de paraffine et 7 parties de résine phénolique active. To make seals for aerosol valves free of chlorine and sulfur usable for conditioning with dimethyl ether, according to the invention, a mixture of elastomers containing 100 parts of butyl elastomer, 1.5 parts of stearic acid will be prepared. , 5 parts of zinc oxide, 50 parts of carbon black, 10 parts of calcined kaolin, 7.5 parts of paraffin oil and 7 parts of active phenolic resin.
