Description

Plastische Massen Aus der USA.-Patentschrift 2 249 686 ist es bekannt, plastische Massen aus Superpolyamiden unter Zusatz von kautschukartigen Polymerisationsprodukten herzustellen. Dieser Vorschlag hat jedoch den Nachteil, daß die Superpolyamide zumeist feste hornartige Massen sind, die sich nur schwer unter Aufwendung von Hitze mit den kautschukartigen Polymerisationsprodukten verarbeiten lassen.Plastic masses From US Pat. No. 2,249,686 it is known plastic masses made from superpolyamides with the addition of rubber-like polymerisation products to manufacture. However, this proposal has the disadvantage that the superpolyamides mostly are solid, horn-like masses that are difficult to deal with with the application of heat process the rubber-like polymerization products.

Es wurde nun gefunden, daB die Superpolyurethane, die durch einen acyclischen oder cyclischen Kohlenwasserstoffrest substituiert sind, sich leicht mit hochmolekularen kautschukartigen Polymerisationspredukten aus ungesättigten alipiratischen Kohlenwasserstoffen oder deren Halogenierungsprodukten, insbesondere natürlichem oder synthetischem Kautschuk, homogen verarbeiten lassen und hochelastische, widerstandsfähige verformbare Massen ergeben.It has now been found that the super-polyurethanes, which by a acyclic or cyclic hydrocarbon radical are easily substituted with high molecular weight, rubber-like polymerization precursors made from unsaturated aliphatic hydrocarbons or their halogenation products, in particular natural or synthetic rubber, can be processed homogeneously and highly elastic, result in resilient deformable masses.

Superpolyurethane der angegebenen Art sind in bekannter Weise, z. B. durch Umsetzung von Diisocyanaten mit Glykolen oder auch durch Umsetzung von Dicarbonaten oder Dicarbaminsäureestern von Glykolen mit Diaminen erhältlich und können z. B. aus 3-Methyl-r, 6-hexamethylendiamin und i, 5-Pentandiol-di-phenylcarbonat oder 3-Methyl-hexandiol-r, 6 und z, 6-Hexamethylendiisocyanat oder z', 2'-Dioxyr, 2-diäthylcyclohexan oder 3-Cyclohexyl-hexandiol -i, 6 und i, io-Dekamethylendiisocyanat oder 3 - Methyl - hexandiol - i, 6 - diphenylcarbonat und i, 7-Heptamethylendiamin erhalten werden.Super-polyurethanes of the type specified are known in a known manner, for. B. by reacting diisocyanates with glycols or by reacting Dicarbonates or dicarbamic acid esters of glycols with diamines available and can e.g. B. from 3-methyl-r, 6-hexamethylenediamine and i, 5-pentanediol-diphenyl carbonate or 3-methyl-hexanediol-r, 6 and z, 6-hexamethylene diisocyanate or z ', 2'-dioxyr, 2-diethylcyclohexane or 3-cyclohexylhexanediol -i, 6 and i, io-decamethylene diisocyanate or 3 - methyl - hexanediol - i, 6 - diphenyl carbonate and i, 7-heptamethylene diamine can be obtained.

Die vorgeschlagenen Polyurethane stellen krümlige Massen dar, die eine gewisse Klebrigkeit aufweisen, ohne jedoch feucht zu sein. Sie ähneln dem Ölfaktis und lassen sich zusammen mit kautschukartigen Polymerisationsprodukten,wie natürlichem oder synthetischem Kautschuk, Polyisobutylen oder Chlorkautschuk, leicht durch Verwalzen miteinander vereinigen. Man erhält hierbei Mischungen, die sich in üblicher Weise auf Vulkanisate verarbeiten lassen, aber auch zu festen biegsamen Filmen verformt werden können. Das Mischungsverhältnis zwischen Superpolyurethanen und kautschukartigen Polymerisationsprodukten kann in weiten Grenzen schwanken.The proposed polyurethanes represent crumbly masses that have a certain stickiness, but without being damp. They are similar to the oil factories and can be mixed with rubbery polymerization products such as natural or synthetic rubber, polyisobutylene or chlorinated rubber, easily by rolling unite with each other. This gives mixtures which can be mixed in the usual way can be processed on vulcanizates, but also formed into firm, flexible films can be. The mixing ratio between super-polyurethanes and rubber-like ones Polymerization products can vary within wide limits.

Die plastischen Massen der vorgeschlagenen Art können für die Herstellung von elastischen Fäden, Bändern, Folien, Schläuchen, Dichtungs- und Polstermaterial od. dgl. verwendet werden. Beispiel i 5o Gewichtsteile natürlicher Kautschuk und 5o Gewichtsteile eines Superpolyurethans aus 3-Methylhexamethylendiamin-i, 6 und i, 5-Pentandiol-diphenylcarbonat, das eine schwach gelblich gefärbte krümlige elastische Masse darstellt, werden miteinander in der Wärme bei 1¢o bis i5o° verwalzt. Hierbei wird ein homogenes Fell erhalten, das zu dünnen Folien ausgezogen werden kann, die sich zu Bändern oder Fäden von hoher Elastizität und Widerstandsfähigkeit gegen mechanische und chemische Einflüsse verarbeiten lassen.The plastic masses of the proposed type can be used for manufacture of elastic threads, tapes, foils, hoses, sealing and cushioning material or the like. Can be used. Example i 50 parts by weight of natural rubber and 5o parts by weight of a super-polyurethane from 3-methylhexamethylenediamine-i, 6 and i, 5-pentanediol diphenyl carbonate, which is a pale yellowish colored crumbly elastic Mass represents, are rolled together in the heat at 1 ¢ o to 15o °. Here a homogeneous fur is obtained, which can be pulled out into thin sheets, the become ribbons or threads of high elasticity and resistance to Allow mechanical and chemical influences to be processed.

Beispiel z 2o Gewichtsteile Butadienkautschuk und 2o Ge- wichtsteile eines Superpolyurethans aus 3-Methylhexandiol-i, 6-diphenylcarbonat und i, 6-Hexamethylendiamin werden zusammen mit q.o Gewichtsteilen Gasruß, io Gewichtsteilen Kaolin, 5 Gewichtsteilen Zinkoxyd, 3 Gewichtsteilen Dammarharzalkohol, 2 Gewichtsteilen Schwefel und o,5 Gewichtsteilen pentamethylendithiocarbaminsaurem Piperidin auf der Walze miteinander homogen vermischt und nach Verformung zu Schläuchen während q0 Minuten bei 1q.8° vulkanisiert. Man erhält ein hochelastisches und sehr widerstandsfähiges Material.Example z 2o parts by weight of butadiene rubber and 2o by weight of a Super polyurethane from 3-Methylhexandiol-i, 6-diphenyl carbonate and i, 6-hexamethylenediamine, together with qo parts by weight of carbon black, io weight parts of kaolin, 5 parts by weight of zinc oxide, 3 parts by weight Dammarharzalkohol, 2 parts by weight sulfur and 0.5 parts by weight of pentamethylenedithiocarbamic acid piperidine mixed homogeneously with one another on the roller and vulcanized after shaping into tubes for q0 minutes at 1q.8 °. A highly elastic and very resistant material is obtained.
