Description

Konservierungsmittel für Gummiwaren Die Erfindung bezieht sich auf Konservierungsmittel für Gummiwaren aller Art.Preservatives for rubber goods The invention relates to Preservatives for rubber goods of all kinds.

Es ist bekannt, daß Gummiwaren beim Gebrauch und auch schon lediglich bei längerem Lagern an der Luft leicht spröde und rissig werden, da der Sauerstoff der Luft oxydierend auf den vulkanisierten Kautschuk einwirkt. Man hat zwar bereits eine Reihe von Konservierungsmitteln vorgeschlagen, um diesem Nachteil zu begegnen. Der gewünschte Erfolg konnte jedoch damit bisher nicht erzielt werden.It is known that rubber goods in use and even only can easily become brittle and cracked after long periods of storage in the air, because of the oxygen the air has an oxidizing effect on the vulcanized rubber. You already have a number of preservatives have been proposed to address this disadvantage. However, the desired success has not yet been achieved with it.

Zu einem unerwarteten Erfolg führten Konservierungsmittel, die nach der Erfindung auf der Grundlage von künstlichem oder natürlichem Harz und sogenannten. Weichmachungsmitteln in etwa gleichen Mengenverhältnissen hergestellt werden. Diese homogeien Mischungen verbinden sich außerordentlich fest mit der Gummiunterlage, und es wohnt ihnen die genügende Elastizität inne,, die für Guininistofte unbedingt notwendig ist.Preservatives after of the invention based on artificial or natural resin and so-called. Plasticizers are produced in approximately the same proportions. These homogeneous mixtures bond extremely firmly with the rubber base, and they have sufficient elasticity inherent, which is essential for Guininistofte necessary is.

Als Zusatz zu den Harzen eignen sich z. B. Tributvlphosphat, Trikresylphosphat, ferner Harnstoffderivate, wie z. B. Diäthyl:diphenylharnstoff u. dgl.Suitable additives to the resins are, for. B. tributyl phosphate, tricresyl phosphate, also urea derivatives, such as. B. Diethyl: diphenylurea and the like.

Für den Gebrauch wird dieses Stoffgemisch zweckmäßig mit einem Lösungsmittel, z. B. Äthylalkohol, aufgenommen.For use, this mixture of substances is expediently mixed with a solvent, z. B. ethyl alcohol added.

Es können noch andere Stoffe liin7ugesetzt werden, um die Wirkung als Konservierungsmittel zu erhöhen, z. B. nichttrocknende Öle, wieRizinu:söl, sowie benetzungsfö.rdernde Substanzen, wie z. B. alkylnaphthalinsulfonsaure Alkalisalxe, ferner oxydationshindernde S to-ffe, wie z. B. Hydrochinon, Naphthole o. dgl.Other substances can be added to the effect as a preservative, e.g. B. non-drying oils such asRizinu: söl, as well as wetting-promoting substances, such as B. alkylnaphthalenesulfonic acid alkali metal salts, also oxidation-preventing S to-ffe, such. B. hydroquinone, naphthols or the like.

Es ist noch hervorzuheben, daß die Gummiwaren einen hervorragenden Glanz bekommen.

Zu einer Lösung von 8,5 Teilen Akkaroidharz in 85 Teilen Sprit werden 1i,25 Teile Diätlyldiphenylharnstoff zugegeben, die mit o,25 Teilen I-fy.drocliinoii vorsetzt sind.To a solution of 8.5 parts of accharoid resin in 85 parts of gasoline 1i, 25 parts of dietlyldiphenylurea added, with 0.25 parts of I-fy.drocliinoii are in front.
