Description

Vulkanisierbare Kautschukmischungen mit elastischen Glycerinestern Es ist bekannt, daß die Glyeerinestex höherer Paraffin- oder Olefindicarbonsäuren, ihrer Derivate und Hamologen elastische faktisähnliche Erzeugnisse darstellen, die sich zusammen mit Kautschukkohlenzvas'serstoffen gut verarbeiten lassen und homogene vulkan sierbare Mischungen ergeben. Es wurde nun .gefunden, daß die Ester aus Glycerin und höheren Paraffin- oder Oleßudi:carbonsäunen und ihren Derivaten :er- heblich bessere erweichende Eigenschaft in natürlichem und ganz besonders künst- lichem Kautschuk und anderen kautschukarti- gen Masseen zeigen, wenn bei ihrer Herstel- lung solche höhermolekularen eimbas@schen Carbonsäuren mitverwendet werden, die in Form ihrer Alkalisalae seifenartige Eigen- schaften zeigen. Derartige Säuren sind in erster Linie die höhermalekularen Fettsäuren, i'hsbesondere solche ungesättigter Natur, wie ölsäure und Rizinusölsäure, ferner auch Di- isobutylkresoxyessigsäure, Perhydrophenyl- naphthylinetbancarbonsäure, Cholsäure, Abie- tInsäure und Naphthensäuren. Die Herstel- lung derartiger gemischter Kondensations,- produkte kann in der- Weise erfolgen, daß man die -Paraffin- oder Olefindicarbonsäure zugleich mit der Monocarbonsäure und dem Glycerin kondensiert. Es ist jedoch auch an- gängig, daß man zunächst die mehrbasische Säure mit dem Glycerin, verestert und als- dann die Monocarbonsäune auf das noch freie Hyd oxylgruppen lenthaltende Konden- sationsprodukt ,einwirken läßt oder umge- kehrt. Hierbei können die Verhältnisse für Monocarbonsäurc, Dicarbonsäune und Glycerin. in weiten Grenzen schwanken.Vulcanizable rubber compounds with elastic glycerine esters It is known that the Glyeerinestex higher paraffin or olefin dicarboxylic acids, their derivatives and hemologists elastic represent factual products that together with rubber carbon fibers Can be processed well and homogeneous volcano yieldable mixtures. It has now been found that the esters made of glycerine and higher paraffin or Oleßudi: carbon acids and their derivatives: significantly better emollient property in natural and especially artificial natural rubber and other types of rubber towards masses show if in their manufacture such higher molecular weight eimbas @sch Carboxylic acids are also used, which in Form of their alkali alcaline soap-like peculiarities show properties. Such acids are in first and foremost the higher molecular fatty acids, especially those of an unsaturated nature, such as oleic acid and ricinoleic acid, and also di- isobutylcresoxyacetic acid, perhydrophenyl naphthylinetbancarboxylic acid, cholic acid, abie- tinic and naphthenic acids. The manufac- development of such mixed condensation, products can be made in such a way that one the -paraffin or olefin dicarboxylic acid at the same time with the monocarboxylic acid and the Glycerin condensed. However, it is also It is common to first use the polybasic Acid with the glycerine, esterified and as- then the monocarboxy on top of that still condensate containing free hydroxyl groups sation product, allowed to act or returns. The ratios for monocarboxylic acid, dicarboxylic acid and glycerine can be used here. fluctuate within wide limits.

Die unter Mitverwendung höhermolek@-larer einbasischer Carbonsäurem herges4rt=. ten Kondensationsprodukte aus Glycerin und aliphatischen Dicarbonsäuren gesättigter oder, ungesättigter Natur zeichnen sich gegenüber den bereits für Mischungen mit natürlichem. oder synthetischem Kautschuk oder Gutta.-percha vorgeschlagenen Glycerinestern dadurch aus, daß sie sehr gute plastifizierende Eigenschaften besitzen.The with the use of higher molecular weight monocarboxylic acids herges4rt =. th condensation products from glycerol and aliphatic dicarboxylic acids Saturated or unsaturated nature stand out over those already used for mixtures with natural. or synthetic rubber or gutta.-percha are suggested Glycerol esters in that they have very good plasticizing properties.

Beispiel 146 Gewichtsteile Adipinsäure, 92 Gewichtsteile Glycerin und 141 Gewichtstelle Ölsäure werden bei 200 bis 220° so lange erhitzt, bis eine zähe, elastische Masse entstanden ist, was nach etwa 5 bis 6 Stunden der Fall ist. Dieses Kondensationsprodukt läßt sich synthetischem. Kautschuk bis zu 20% seines Gewichtes leicht auf der Mischwalze zumischen und liefert nach Zugabe "der üblichen Zusätze bei der Vulkanisation Stunde bei r32°) ein ausgezeichnet widerständsfähiges und zähes Erzeugnis.Example 146 parts by weight of adipic acid, 92 parts by weight of glycerol and 141 weight points of oleic acid are heated at 200 to 220 ° until one tough, elastic mass is formed, which is the case after about 5 to 6 hours. This condensation product can be synthetic. Rubber up to 20% of his Mix in weight easily on the mixing roller and after adding "the usual." Additives during vulcanization hour at r32 °) an excellent resistance and tough product.
