Description

Vulkanisationsbeschleuniger -Das Patent 6¢6 196 betrifft die Verwendung vonkeaktionsprodukten von as-Dichloraceton mit K-disubstituierten Dithiocarbaminsäuren oder deren Salzen der Formel worin R einen aliphatischen oder aromatischen Rest, R1 einen aliphatischen oder alicy clischen Rest und R # R1 auch gemeinsam eine Alkylenkette bedeuten, als Vulkanisationsbeschleuniger für Kautschuk und künstliche kautschukähnliche Produkte.Vulcanization accelerator - Patent 6 [6,196] relates to the use of reaction products of α-dichloroacetone with K-disubstituted dithiocarbamic acids or their salts of the formula where R is an aliphatic or aromatic radical, R1 is an aliphatic or alicyclic radical and R # R1 also together mean an alkylene chain, as a vulcanization accelerator for rubber and synthetic rubber-like products.

Es wurde nun gefunden, daß man an Stelle der genannten Produkte auch solche Umsetzungsprodukte der obengenannten Formel verwenden kann, bei denen R und R1 alicyclische Reste bedeuten.It has now been found that instead of the products mentioned, can use such reaction products of the above formula in which R and R1 mean alicyclic radicals.

Die fraglichen Produkte entsprechen also der Formel- Die neuen Beschleuniger besitzen wie die des Hauptpatents eine gute Wirksamkeit in Verbindung mit hoher kritischer Temperatur und sind bezüglich letzterer den bekannten Salzen der Dialkyldithiocarbaminsäur en beträchtlich überlegen.. Hinsichtlich der Überlegenheit der neuen Beschleuniger gegenüber anderen bekannten Beschleunigern gilt das im Hauptpatent Gesagte. Beispiel In einer Prüfmischung der Zusammen-. setzung: ioo Gewichtsteile heller Crepe . - Zinkoxyd 2,5 - Schwefel i Gewichtsteil Stearinsäure wurden mit dem Umsetzungsprodukt aus asyrn. Dichloraceton-und Dicyclohexyldithiöcarbaminsäure (A) im Vergleich zu dem bekannten cyclopentamethylendithiocarbaminsauren Piperidin (B) folgende Werte erhalten: Heizung A-o,5 °/o B-0,3% '/, Atm. keine =8g kg/cm2 30 Min. Vulkanisation bei 895 % Dehnung z Atm. 180 kg/cm2 222 kg/cm22 5o Min. bei895%Dehnung beigo2%Dehnung. Ersetzt man in diesem Beispiel das Umsetzungsprodukt aus asym. Dichloraceton und Dicyclohexyldithiocarbamirisäure durch das Umsetzungsprodukt aus asym. Dichloraceton mit Cyclohexylmethylcyclohexyldithiocarbaminsäure, so werden ähnliche Vulkanisationswerte wie unter. A angegeben erhalten.The products in question therefore correspond to the formula The new accelerators, like those of the main patent, have good effectiveness in conjunction with a high critical temperature and, with regard to the latter, are considerably superior to the known salts of dialkyldithiocarbamic acids. With regard to the superiority of the new accelerators over other known accelerators, what was said in the main patent applies. Example In a test mix of the. Setting: 100 parts by weight of light crepe. - Zinc oxide 2.5 - sulfur 1 part by weight of stearic acid were mixed with the reaction product from asyrn. Dichloroacetone and dicyclohexyldithiocarbamic acid (A) obtained the following values in comparison with the known cyclopentamethylene dithiocarbamic acid piperidine (B): Heating Ao, 5 ° / o B-0.3% '/, Atm. none = 8g kg / cm2 30 min. Vulcanization at 895 % elongation z Atm. 180 kg / cm2 222 kg / cm22 5o min. At 895% elongation at 2% elongation. If, in this example, the reaction product of asym. Dichloroacetone and dicyclohexyldithiocarbamic acid is replaced by the reaction product of asym. Dichloroacetone with cyclohexylmethylcyclohexyldithiocarbamic acid, vulcanization values are similar to those below. A specified received.
