Description
Verfahren zur Vereinigung von Leder und Gummi. Bei den bekannten Verfahren zur Vereinigung von Leder mit Gummi wird darauf geachtet, daß lufttrockenes (an der Luft oder in der Sonne getrocknetes) Leder verwendet wird, da feuchtes Leder keine innige Verbindung mit dein Gummi eingeht und bei der @'tilkanisation brüchig wird. Die bei der Verwendung feuchten Leders auftretenden Übelstände lassen sich jedoch durch die Verwendung lufttrockenen. Leders nicht völlig, sondern nur bis zu gewissem Grade beseitigen.Process for the union of leather and rubber. With the known methods When combining leather with rubber, care is taken to ensure that air-dry (an leather that has been dried in the air or in the sun) is used because the leather is damp does not enter into an intimate connection with your rubber and is brittle during @ 'tilcanization will. The inconveniences that arise when using damp leather can be eliminated however, by using air-dry. Leather not completely, but only up to eliminate to some extent.
Gemäß der Erfindung wird das lufttrockene Leder noch einem weiteren Trockenprozesse unterworfen, und zwar wird ihm etwa 24. Stunden lang in einem Luftbade von etwa 5o° weitere Feuchtigkeit entzogen.According to the invention, the air-dry leather becomes yet another It is subjected to drying processes, namely in an air bath for about 24 hours further moisture removed from about 50 °.
Dieses Leder muß dann entweder sofort mit dem Gummi vereinigt oder unter Luftabschluß bis zur Verarbeitung aufbewahrt werden, da es andernfalls von neuem Feuchtigkeit aufnimmt, die sich nur durch Gewichtszunahme des Leders feststellen läßt.This leather must then either immediately be combined with the rubber or must be kept air-tight until processing, otherwise it will be affected by absorbs new moisture, which can only be determined by the increase in weight of the leather leaves.
Man kann auch das gemäß Erfindung getrocknete Leder sofort in eine Lösung von Gummi in Benzin eintauchen und hierdurch die feinen Poren des Leders gegen den Zutritt von Feuchtigkeit abschließen.You can also the leather dried according to the invention immediately in a Dip the solution of rubber in gasoline and thereby the fine pores of the leather lock against the ingress of moisture.
Nach diesem Verfahren lassen sich auch mit Abfalleder gute Endprodukte erzielen. Als Bindemittel zwischen Gummi und Leder wird zweckmäßigerweise eine Lösung von Gummi in Benzin verwendet. Die Festigkeit und Geschmeidigkeit des Erzeugnisses läßt sich durch Vulkanisation steigern. Hierbei zeigt sich ein weiterer Vorteil der Vortrocknung. Man kann nämlich mit der Vulkanisationstemperatur bis auf --2oo° gehen und den Vulkanisationsprozeß entsprechend abkürzen, ohne daß das Erzeugnis an Geschmeidigkeit verliert.This process can also be used to produce good end products with waste achieve. A solution is expediently used as a binding agent between rubber and leather of rubber used in gasoline. The strength and suppleness of the product can be increased by vulcanization. Another advantage is evident here the pre-drying. You can use the vulcanization temperature down to --2oo ° go and shorten the vulcanization process accordingly without affecting the product loses suppleness.
