Verfahren zur Herstellung von Kautschukmischungen
EMI1.1
<Desc/Clms Page number 2>
Vormischung wird dann unter Zusatz von etwa 1, 71o Schwefel und 0, 40/0 Beschleuniger in etwa 6 Minuten die Fertigmischung erhalten.
Wenn in der ersten Vormischung statt 0. 36 kg Renacit IV nur 0, 15 kg Renacit IV angewendet werden, so zeigt diese Vormischung eine Defohärte von etwa 1800 Graden. Es ist also möglich, mit verschiedenen Mischzeiten bei den einzelnen Vormischungen und mit verschiedenen Renacit-IV-Mengen alle gewünschen Defowerte zwischen 500 und 900 Punkten für die Fertigmischung zu erreichen. Dies war bisher nur bei Einsatz von tief vormastiziertem Kautschuk möglich (Mastizierzeit 180 kg in 13 Minuten).
Nach dem vorliegenden Verfahren erhält man also die Fertigmischung über die erste und zweite Vormischung, zusammen in 33/4 + 3 + 6 Minuten, d. s. 12 3/4 Minuten bzw. 3 3/4 + 3 1/4 + 6 = 13 Minuten, während das bisherige Verfahren 20 3/4 Minuten in beiden Fällen erforderte.
Bei der erfindungsgemässen Arbeitsweise wird aber nicht nur Zeit gewonnen, sondern es sind ausserdem auch noch wesentliche Ersparnisse an Energie möglich.
EMI2.1
:1. Verfahren zur Herstellung von Kautschukmischungen, welche Pentachlorthiophenol oder dessen Zinkverbindung enthalten, dadurch gekennzeichnet, dass zunächst aus Naturkautschuk, Pentachlorthiophenol oder dessen Zinkverbindung und einer Russteilmenge eine erste Vormischung mit hoher Defohärte hergestellt, aus dieser Vormischung durch Zusatz des restlichen Russes, Weichmachern, Alterungsschutzmitteln und Zinkoxyd eine zweite, weniger harte Vormischung gebildet und aus derselben durch Zusatz von Schwefel und Beschleunigern unter weiterer Verminderung der Defohärte die Fertigmischung erhalten wird.

Process for the production of rubber compounds
EMI1.1

Premix is then obtained with the addition of about 1.71o sulfur and 0.40/0 accelerator in about 6 minutes.
If only 0.15 kg Renacit IV are used in the first premix instead of 0.36 kg Renacit IV, this premix shows a defo hardness of around 1800 degrees. It is therefore possible, with different mixing times for the individual premixes and with different Renacit IV quantities, to achieve all the desired defo values between 500 and 900 points for the finished mixture. Up to now this was only possible with the use of deeply pre-masticated rubber (mastication time 180 kg in 13 minutes).
According to the present method, the finished mix is obtained via the first and second premixes, together in 33/4 + 3 + 6 minutes, i.e. s. 12 3/4 minutes or 3 3/4 + 3 1/4 + 6 = 13 minutes, while the previous procedure required 20 3/4 minutes in both cases.
In the procedure according to the invention, not only is time saved, but also substantial savings in energy are possible.
EMI2.1
:1. Process for the production of rubber mixtures which contain pentachlorothiophenol or its zinc compound, characterized in that a first premix with high defo hardness is produced from natural rubber, pentachlorothiophenol or its zinc compound and a partial amount of carbon black, from this premix by adding the remaining carbon black, plasticizers, anti-aging agents and zinc oxide a second, less hard premix is formed and the finished mixture is obtained from it by adding sulfur and accelerators while further reducing the defo hardness.
