Description

Herstellung von weidigunimiartigen Schläuchen, Platten, Stäben u. dgl. aus Poiyvinylchlorid Es ist bekannt, Schläuche; Platten, Stäbe u. dgl. aus Polyvinylchlorid unter Zusatz von Weichmachern mit oder ohne Füllstoffe herzustellen. Diese Schläuche usw. haben eine mehr oder weniger große Weichheit und Elastizität, die durch Abstufung der Menge des Weichmachers weitgehend verändert werden können.Production of weidigunimi-like hoses, plates, rods and the like. Like. Made of polyvinyl chloride It is known that hoses; Plates, rods and the like Manufacture polyvinyl chloride with the addition of plasticizers with or without fillers. These hoses etc. have a more or less great softness and elasticity, which can be largely changed by varying the amount of plasticizer.

überraschenderweise wurde üun gefunden, daft die Elastizität ganz. erheblich gesteigert werden kann, wenn man die weichmacherhaltigen Schläuche, Platten, Stäbe ü. dgl. kurze Zeit in Kresole, Phenol oder Nitrobenzole einlegt.Surprisingly, it has been found that the elasticity is complete. can be increased significantly if the plasticized hoses, plates, Rods Like. Inserted a short time in cresols, phenol or nitrobenzenes.

Beispiel i 5o Teile hochpolymeres Polyvinylchlorid und 5o Teile Trikresylphosphat werden' in einer Schnecke durchmischt und bei 12o bis i 5o' in einer Schlauchspritzmaschine zu Schläuchen verspritzt.. Die Schläuche werden dann 12. Stunden in Nitrobenzol eingelegt und hierauf in heißem Wasser abgewaschen. Sie sind dadurch Weitgehend. gummiartig geworden.Example i 50 parts of high polymer polyvinyl chloride and 50 parts of tricresyl phosphate are mixed 'in a screw and at 12o to i 5o' in a hose injection molding machine sprayed into hoses .. The hoses are then 12 hours in nitrobenzene inserted and then washed in hot water. You are thereby largely. become rubbery.

Beispiel 2 Ein Polyvinylchloridschlauch wie bei Beispiel i wird in Aceton gelegt, bis er weich geworden ist, abgetrocknet, 1/Q Stunde in Nitrobenzol gelegt und dann kurze Zeit in heißem Wassergewaschen. Auch so wird ein durchaus gummiartiger Schlauch gewonnen. Beispiel 3 Verfährt man gemäß Beispiele, legt aber den Schlauch statt in Nitrobenzol in Kresol oder Phenoi und behandelt ihn -weiter, wie in Beispie12 angegeben, so gelangt man zum gleichen Ergebnis.Example 2 A polyvinyl chloride tube as in Example i is shown in Acetone placed until it has softened, dried, 1 / Q hour in nitrobenzene and then washed in hot water for a short time. Even so, it will definitely be rubbery hose won. Example 3 If one proceeds according to the examples, but lays the hose in cresol or phenoi instead of nitrobenzene and treats it further, as indicated in example12, one arrives at the same result.

Es ist zwar bereits bekannt, die mechanischen Eigenschaften von schichtenförmigen Gebilden ,aus Polyvinylchlorid durch Behandlung mit solchen organischen Lösungsmitteln zu verbessern, die das Hochpolymere selbst nicht läsen, wohl aber die bei der Herstellung der Polyvinylchloridformkörper mitverwendeten Weichmacher und hochsiedenden Lösungsmittel. .Die dabei zu erzielenden Verbesserungen der Gesamtdehnung reichen jedoch bei weitem nicht an die Elastizitätssteigerungen,-heran, die durch die - Nachbehandlung von Polyvinylchlorid mit Kresolen, Phenol oder Nitrobenzolen erhalten werden, wobei keinerlei nennenswerte Extraktion der Weichmacher eintritt, sondern vielmehr ein Eindringen des Nachbehandlungsmittels in die . behandelte Masse.Although it is already known the mechanical properties of layered Formed from polyvinyl chloride by treatment with such organic solvents to improve that do not let the high polymer itself, but that during production the polyvinyl chloride moldings also used plasticizers and high-boiling solvents. The improvements in overall elongation that can be achieved in this way, however, are far reaching not to the increases in elasticity caused by the after-treatment of Polyvinyl chloride can be obtained with cresols, phenol or nitrobenzenes, with No significant extraction of the plasticizer occurs, but rather one Penetration of the aftertreatment agent into the. treated mass.
