Description
Verfahren zur Herstellung hochelastischer homogener bituminöser Überzugsmassen mit einem Zusatz von Kautschuk Die Erfindung betrifft ein Verfahren zur Herstellung'von überzugsxnassen, z. B. für Metallkörper zu Rost;schutzzwecken o. dgl., die hochelastisch sind, nicht verspröden und nicht erhärten. Die überzugsmassen gemäß der Erfindung bestehen im wesentlichen aus Bitumen, dem Kautschuk in nicht unerheblichen Mengen .einverleibt wird.Process for the production of highly elastic, homogeneous bituminous coating compounds with an addition of rubber The invention relates to a method for producing coating x wet, e.g. B. for metal bodies to rust; protective purposes o. The like. The highly elastic are, do not become brittle and do not harden. The coating compositions according to the invention consist essentially of bitumen, the rubber in not inconsiderable quantities . is incorporated.
Überzüge aus bituminösen Substanzen weisen .an und für sich vorzügliche Eigenschaften auf, aber auch den Nachteil, der der ganzen Körperklasse ;anhaftet, bei niederen Temperaturen zu erhärten und zu vers.pröden.Coatings made from bituminous substances are excellent in themselves Properties, but also the disadvantage that the whole body class; adheres to, to harden and become brittle at low temperatures.
Nun hat man bereits vorgeschlagen, diesem Nachteil dadurch zu begegnen, daß man bituminösen Substanzen Kautschuk einverleibt. Bei derartigen Versuchen machte sich jedoch die schwere Löslichkeit des I<auts,chuks in geschmolzenem Bitumen störend bemerkbar. Man mußte auf Temperaturen zwischen 200 bis 3oo° gehen, um ein honiogenes Gemisch beider Substanzen zu erhalten, und konnte dabei eine weitgehende Zerstörung des Kautschukmoleküls in keinem Falle vermeiden.It has already been proposed to counter this disadvantage by that rubber is incorporated into bituminous substances. Made in such attempts However, the poor solubility of I <auts, chuks in molten bitumen noticeably disturbing. You had to go to temperatures between 200 and 300 degrees to get a To obtain a honeyed mixture of the two substances, and was able to achieve an extensive one In no case avoid destroying the rubber molecule.
Von den wertvollen Eigenschaften des Kautschuks waren dementsprechend in dem Fertigprodukt nur geringe, Reste erhalten.The valuable properties of rubber were accordingly only small residues are preserved in the finished product.
Auch hat man vorgeschlagen, eine Überzugsmasse dadurch herzustellen, daß man in eine erwärmte weiche Masse aus zusammengeschmolzenem Bitumen und Ceresinoder Candelillawachs Kautschuk portionsweise einknetet. Es ist jedoch durch Versuche festgestellt worden, daß man auf diese Weise zu keinen homiog@enien Massen gelangt, da der Kautsrch'uk sich nicht gleichmäßig in der bituminösen Masse verteilen läßt.It has also been proposed to produce a coating mass by that one is in a heated, soft mass of melted bitumen and ceresin or Knead candelilla wax in portions. It is, however, by trial and error it has been established that one does not arrive at homogeneous masses in this way, because the Kautsrch'uk cannot be distributed evenly in the bituminous mass.
Die Erfindung beruht ,auf der neuen Erkennt.nis, daß man ein völlig homogenes Gemisch von Kautschuk und Bitumen bei wesentlich niedrigeren Temperaturen, nämlich bei Temperaturen von i 5o bis 16o' und somit unter weitgehender Erhaltung der Eigenschaften des. Kautschuks herstellen. kann, wenn man ihn zunächst mit z. B. der gleichen Menge Chlornaphthalin schmilzt, gegebenenfalls die Schmelze in einer geheizten Knetmaschine homogenisiert und sie danach in wechselnde Mengen geschmolzenen Bitumens einträgt. Man erhält auf diese Weise hochelastische, nicht versprödende Massen, die sich leicht in Bandform bringen und als rostschützender Überzug beispielsweise auf eisernen Rohren mit Vorteil verwenden lassen. Den Massen nach der Erfindung können erforderlichenfalls auch Füllstoffe, wie Kaolin, Kieselgur loder andere, .einverleibt werden: Beispiel 25o Teile Rohkautschuk werden bei 150 bis, i 6o° in 25o Teilen. wachsähnlichem Chlbrnaphthalin geschmolzen, und die Schmelze wird nach dem Homogenisieren in 2ooo Teile geschmolzenes Petrolbitumen, Schmelzpunkt 6o bis 70°, eingetragen.The invention is based on the new knowledge that a completely homogeneous mixture of rubber and bitumen can be produced at significantly lower temperatures, namely at temperatures from 150 to 16o 'and thus while largely maintaining the properties of the rubber. can, if you first start with z. B. the same amount of chloronaphthalene melts, if necessary, the melt is homogenized in a heated kneading machine and then enters it in varying amounts of molten bitumen. In this way, highly elastic, non-embrittling masses are obtained which can easily be put into strip form and which can be used with advantage as a rust-protecting coating, for example on iron pipes. If necessary, fillers such as kaolin, kieselguhr or others can also be incorporated into the compositions according to the invention: Example 250 parts of crude rubber are converted into 250 parts at 150 to. melted wax-like chlorine naphthalene, and after homogenization, the melt is introduced into 2,000 parts of molten petroleum bitumen, melting point 60 ° to 70 °.
