Description

Verfahren zur Verbesserung der Eigenschaften von Kautschuk und seinen Ersatzstoffen Es wurde gefunden, daß Kautschuk sowie seine Ersatzstoffe, z. B. Butadiennatriumpolymerisat und andere kautschukähnliche Polymerisate, durch Zusätze von Chlorparaffinen; insbesondemehöheren Chlorparaffinen, in ihren Eigenschaften sehr günstig beeinflußt werden. Die -Chlorparaffine üben eine stark weichmachende Wirkung aus. Man kann die Verschiedensten Chlarierungsstufen der Paraffine anwenden. Ferner kann man sowohl von festem als auch von flüssigem Paraffin dies Handels ausgehen, das man verschieden hoch chloriert hat. Da die Chlorparaffine eine gewisse Neigung haben, Salzsäure abzuspalten, kann man den Mischungen solche Stoffe zusetzen, die die abgespaltene Sialzs.äure abfangen, wie z. B. Salze schwacher Säuren oder seifenartige Stoffe. Auch kann man von vornherein ein stabilisiertes Chlorparaffin verwenden, wie man es nach der Patentschrift 674 422 erhalten kann.Process for improving the properties of rubber and its substitutes It has been found that rubber and its substitutes, e.g. B. sodium butadiene polymer and other rubber-like polymers, by adding chlorinated paraffins; especially higher chlorinated paraffins, their properties can be influenced very favorably. The chlorinated paraffins have a strong softening effect. The most varied levels of chlorination of the paraffins can be used. Furthermore, this trade can be started from both solid and liquid paraffin that has been chlorinated to different degrees. Since the chlorinated paraffins have a certain tendency to split off hydrochloric acid, substances can be added to the mixtures which intercept the split off sialic acid, such as B. Salts of weak acids or soap-like substances. Also you can use a stabilized chlorinated paraffin from the outset how to get it to the Patent 674,422.

Der Zusatz der Chlorparaffine kann in bekannter Weise in den verschiedenen Stadien der Verarbeitung der Kautsichukstoffe erfolgen. Die Menge des Zusatzes kann in weiten Grenzen schwanken.The chlorinated paraffins can be added in a known manner in the various Stages of processing of the chewable materials take place. The amount of additive can be fluctuate within wide limits.

Durch den Zusatz von Chlornaphthalin hat man bereits versucht, den Kautschuk unentflammba-r zu machen. 'Es zeige sich aber, daß man befriedigende Wirkungen auch in bezug auf die Qualität nur erhält, wenn man gleichzeitig Chlorkautschuk .oder Polyvinylchlori:d hinzufügt. Auch Selen wurde als weiteres Zusatzmittel vorgeschlagen. Weiterhin ist es bekannt, daß Chlorparaffin ein Lösungsmittel für Chlorkautschuk ist und daß Lösungen von Chlo@rl>autschulk rund Chln@rparaffin als Weichmacher für Kautschuk @i.enen. können.Attempts have already been made to add chloronaphthalene to the To make rubber non-flammable. 'It turns out, however, that one has satisfactory effects also in terms of quality only obtained if chlorinated rubber is used at the same time . or polyvinylchloride: d adds. Selenium has also been suggested as a further additive. Farther it is known that chlorinated paraffin is a solvent for chlorinated rubber and that Solutions from Chlo @ rl> autschulk around Chln @ rparaffin as a plasticizer for rubber @ i.enen. can.

Die Verwendung von Chlorparaffin für sah allein ist aber bisher nicht vorgeschlagen wöq".-: den. Sie kann auch nicht als nahehegend angesehen werden, da eine Verbesserung der Eigenschaften des Kautschuks oder seiner Ersatzstoffe nicht erwartet cvcrden konnte.The use of chlorinated paraffin for saw alone is not yet available suggested wöq ".-: den. It can also not be regarded as suggestive, there is no improvement in the properties of rubber or its substitutes expected.

Von den Ersatzstoffen des Kautschuks soll der Chlor-a-hutadien-(1, 3)=katitschul; vo:n den vorliegenden Verfahren ausgenommen werden. ebenso wie die Verwendung des nach Patent 654 118 hergestellten Chlorparaffins.Of the substitutes for rubber, the chlorine-a-hutadiene- (1, 3) = katitschul; exempt from the present proceedings. as well as that Use of the chlorinated paraffin produced according to patent 654 118.
