Description
Verfahren zur Herstellung von Kautschukmischungen Gegenstand der Erfindung ist die Verwendung von Diketopiperazinen als Zusatzstoffe in Kautschukmischungen.Process for the production of rubber compounds The subject of the invention is the use of diketopiperazines as additives in rubber compounds.
Die Diketopiperazine können gegebenenfalls auch zusammen mit bekannten Kautschukhilfsmitteln, Weichmachern, Dispergiermitteln, fettsauren Salzen, Stabilisatoren, Verwendung finden.The diketopiperazines can optionally also be used together with known ones Rubber auxiliaries, plasticizers, dispersants, fatty acid salts, stabilizers, Find use.
Durch Zusatz der erfindungsgemäß zu verwendenden Verbindungen zu Kautschukmischungen wird den Vulkanisaten oder Fertigprodukten ein hohes Festigkeitsniveau erteilt, insbesondere wird die Strukturfestigkeit außerordentlich erhöht.By adding the compounds to be used according to the invention to rubber mixtures the vulcanizates or finished products are given a high level of strength, in particular, the structural strength is greatly increased.
Gleichzeitig macht sich die plastizierende Wirkung vorteilhaft bemerkbar. Auf diese `'eise ist es möglich, durch Zugabe von Diketopiperazinen zu hochgefüllten oder mit stark verstraffenden Füll'-stoffen versehenen: Kautschukmischungen die ohne Zusatz nicht erreichbare Spritzbarkeit und Verarbeitbarkeit zu erzielen.At the same time, the plasticizing effect is beneficial. In this way it is possible to get highly filled by adding diketopiperazines or with strongly tightening fillers: rubber mixtures die to achieve unachievable sprayability and processability without addition.
Die erfindungsgemäß beanspruchten Zusatzstoffe sind insbesondere für helle Füllstoffe geeignet, z. B. Oxyde, insbesondere des Magnesiums, Aluminiums, Zinks, Bleis oder Silicate, z. B. Calcium- oder Aluminiumsilicat, bzw. Carbonate, wie Magnesium-oder Calciumcarbonat. Sie können gegebenenfalls auch Anwendung finden in Verbindung miteinander. Auch andere Füllstoffe, wie Ruß, z. B. Gas-, Lichtbogen- oder Flammruß, lassen sich unter Verwendung von Diketopiperazinen leicht in Mischungen einarbeiten.The additives claimed according to the invention are in particular for light fillers suitable, e.g. B. Oxides, especially of magnesium, aluminum, Zinc, lead or silicates, e.g. B. calcium or aluminum silicate, or carbonates, like magnesium or calcium carbonate. They can also be used if necessary in connection with each other. Other fillers, such as carbon black, e.g. B. gas, arc or flame black, can easily be mixed using diketopiperazines incorporate.
Die zuzusetzende Menge der erfindungsgemäß anzuwendenden Verbindungen kann innerhalb weitester Grenzen schwanken. Sie-hängt von der besonderenZusammensetzung der alsDispergiermittel dienenden Verbindung, von der Art und Menge des in der Mischung vorhandenen Füllstoffes sowie von den gewünschten physikalischen und technischen Eigenschaften der herzustellenden Kautschukmassen ab.The amount of the compounds to be used according to the invention to be added can within widest limits fluctuate. It -depends on the particularcomposition of the compound serving as the dispersant, on the type and amount of that in the mixture existing filler as well as the desired physical and technical Properties of the rubber compounds to be produced.
Wie aus dem zur näheren Erläuterung angeführten Ausführungsbeispiel zu entnehmen ist, werden durch den Zusatz von Diketopiperazinen die mechanischen Eigenschaften der Kautschukmischungen wesentlich verbessert.As from the exemplary embodiment cited for a more detailed explanation As can be seen, the addition of diketopiperazines results in the mechanical Properties of the rubber compounds improved significantly.
