Description

Verfahren zur Herstellung von Weichmachern aus vulkanisierten Polymeren Aus Vuljkanisaten von Kunst- oder Naturkautschuk werden seit Jahrzehnten durch thermische und mechanische Einwirkung sogernannte Regenerate hergestellt, die als Kautschukersatz in der Kautschukindustrie Verwendung finden. Nun gibt es aber stark gefüllte Vulkanisate, die so minderwertiges Regenerat ergeben, daß sie für die Kautschukindustrie von geringem Interesse sind. Deshalb hat man schon seit geraumer Zeit versucht, insbesondere durch Sehwelung von Altkautschuk zu wertvolleren Produkten zu kommen. Es ist bekannt, daß sowohl Vulkanisate aus Naturkautschuk wie auch solche aus Kunstkautschuken bei der Schwelung Öle aus Gemischen verschieden hoch siedender Anteile ergeben. Da die Zusammensetzung derselben sehr komplex ist und die Öle keinen großen Wert haben, wurde die Schwelu.ng des Altkautschuks bisher nndht in größerem Maßstab betrieben.Process for the production of plasticizers from vulcanized polymers For decades, vulcanized synthetic or natural rubber has been transformed into thermal and mechanical action so-called regenerated material is produced, which is used as a rubber substitute find use in the rubber industry. But now there are heavily filled vulcanizates, which produce such inferior reclaimed material that they are used for the rubber industry of are of little interest. This is why one has tried for quite some time, in particular to get more valuable products through the visual world of old rubber. It is known, that both vulcanizates from natural rubber as well as those from synthetic rubbers the smoldering result in oils from mixtures of different high-boiling fractions. Since the Composition of the same is very complex and the oils are not of great value, The smelting of the old rubber has not hitherto been carried out on a larger scale.

Es wurde gefunden, daß man wertvolle, als Weichmacher für Lacke und Kunststoffe zu verwendende Stoffe durch Chlorierung der vorzugsweise über i6o° siedenden Anteile erhalten kann. Die leiehtsiedenden werden vorher bei der Destillation zweelcmäßigerweise abgetoppt. IhreMenge ist ver'h-ältrnismäßi,g gering (etwa ioo/o des Schwelöls). Sie können als Lösungsmittel verwandt werden. Die über 25o° (bei 2o Torr) siedenden Rückstände werden zwecks Erzielung hellgefärbter Produkte gleichfalls vorher abgetrennt. Die zwischen i6o und 25o° destillierenden Anteile ergeben bei der Ohlorierung Produkte mit einem Chlorgehalt von etwa 40 '/0; sie sind unbrennbar und verträglich mit den meisten Lackbindemitteln wie N itrocel'lulose, Chlorkautschuk sowie mit Polyvinylchlorid und anderen Kunststoffen. Sie sind meist gelb bis gelbbraun gefärbt.It has been found that valuable as plasticizers for paints and Substances to be used in plastics by chlorination of those preferably boiling above 160 ° Can receive shares. The light-boiling ones are suitably boiled beforehand during the distillation topped off. Their amount is relatively small (about 100 per cent of the smoldering oil). They can be used as solvents. Those boiling over 25o ° (at 2o Torr) Residues are also separated off beforehand in order to obtain light-colored products. The proportions distilling between 160 and 25o ° result in products in the chlorination with a chlorine content of about 40 '/ 0; they are incombustible and compatible with the most paint binders such as nitrocellulose, Chlorinated rubber as well with polyvinyl chloride and other plastics. They are usually yellow to yellow-brown colored.
