Description

Gelatinierungs- und Weichmachungsmittel für Chlorkautschuk Es wurde gefunden, daß die höhermolekularen Nitroparaffine und ihre Abkömmlinge gute Gelatinierungs- und Weichmachungsmittel für Chlorkautschuk darstellen. Die höhermolekularen Nitroparaffine, welche eine oder mehrere Nitrogruppen enthalten können, werden in bekannter Weise zweckmäßig nach dem den Gegenstand des Patents 748977 bildenden Verfahren durch Einwirkung von Salpetersäure auf höhermolekulare Paraffinkohlenwasserstoffe mit gerader oder verzweigter Kette und mindestens 8 zweckmäßig wenigstens I2 Kohlenstoffatomen erhalten. Außer den Nitroparaffinen .sind auch deren Abkömmlinge, insbesondere Nitroparaffinalkohole und deren Ester, gut geeignet. Die Nitroparaffinalkohole können durch Einwirkung aliphatischer Aldehyde auf Nitroparaffine, beispielsweise nach dem den Gegenstand des Patents 925 828 bildenden Verfahren, erhalten und in bekannter Weise mittels ein- oder mehrbasischer Carbonsäuren bzw. mehrbasischer, anorganischer, sauerstoffhaltiger Säuren, wie Borsäure oder Phosphorsäure, in die entsprechenden Ester übergeführt werden.Gelatinizing and plasticizing agents for chlorinated rubber It was found that the higher molecular weight nitroparaffins and their derivatives have good gelatinization properties and represent plasticizers for chlorinated rubber. The higher molecular weight nitroparaffins, which may contain one or more nitro groups are known in the art expediently according to the method forming the subject of patent 748977 Effect of nitric acid on high molecular weight paraffin hydrocarbons with straight or branched chain and at least 8, suitably at least 12 carbon atoms obtain. In addition to the nitroparaffins, there are also their derivatives, in particular nitroparaffin alcohols and their esters, well suited. The nitroparaffin alcohols can by acting aliphatic aldehydes on nitro-paraffins, for example according to the subject of the patent 925 828 forming process, obtained and in a known manner by means of mono- or polybasic carboxylic acids or polybasic, inorganic, oxygen-containing ones Acids, such as boric acid or phosphoric acid, converted into the corresponding esters will.

Dliie erfindungsgemäßen Gelantinierungs- und Weichmachungsmittel lassen sich leicht in Chlorkautschuk einarbeiten und verleihen demselben ausgezeichnete El.astizität und Kältebeständigkeit. The gelling and softening agents according to the invention can be easily incorporated into chlorinated rubber and give it excellent properties Elasticity and resistance to cold.

Dlie Nitroparaffine oder ihre Abkömmlinge sind auch mit anderen hochpolymeren. Stoffen verträglich, so daß man leidht entsprechende Misch- produkte, beispielsweise mit natürlichem Kautschuk, Naturharzen wsw., herstellen kann.Dlie nitroparaffins or their derivatives are also compatible with other high polymers. Compatible with substances, so that one suffers from corresponding mixed Products, for example with natural rubber, natural resins etc. can produce.

Beispiele 1. 30 Gewichtsteile Chlorkautschuk (niedrigviskos) werden in 30 Gewichtsteilen Xylol und 25 Gewichtsteilen Tetrahydronaphthalin gelöst und dieser Lösung 6 Gewichtsteile Nitroparaffine mit einer Kettenlänge von etwa 15 bis 20 Kohlenstoffatomen, in denen 9 Gewichtsteile eines Harzes auf Basis cyclischer Ketone gelöst sind, zugesetzt. Es entsteht ein Lack, dessen Film sich durch hohe mechanische und chemische Widerstandsfähigkeit auszeichnet. Examples 1. 30 parts by weight of chlorinated rubber (low viscosity) become dissolved in 30 parts by weight of xylene and 25 parts by weight of tetrahydronaphthalene and this solution 6 parts by weight of nitro paraffins with a chain length of about 15 to 20 carbon atoms in which 9 parts by weight of a resin based on cyclic Ketones are dissolved, added. The result is a varnish, the film of which is characterized by high mechanical and chemical resistance.

2. 30 Gewichtsteile Chlorkautschuk (niedrigviskos) werden in 70 Gewichtsteilen Tebrahydronaphthalin gelöst und dieser Lösung 3 Gewichtsteile Nitroparaffinalkohole, hergestellt durch Nitrierung eines technischen aliphatischen Kohlenwasserstoffgemisches vom Kp. 280 bis 3400 und anschließende Kondensation mit Formaldehyd (O H-Zahl 144), zugesetzt. Es entsteht ein Lack, der einen zähen, elastischen Film hinterläßt und mit Vorteil zum Imprägnieren von. Papier u. dgl. verwendet wird. 2. 30 parts by weight of chlorinated rubber (low viscosity) are used in 70 parts by weight Tebrahydronaphthalene dissolved and this solution 3 parts by weight of nitroparaffin alcohols, produced by nitration of a technical aliphatic hydrocarbon mixture from bp 280 to 3400 and subsequent condensation with formaldehyde (OH number 144), added. The result is a varnish that leaves a tough, elastic film and with advantage for impregnating. Paper and the like is used.
