Es ist bekannt, daß die Weißwand beim Altern eine mehr oder weniger große Neigung zum Gelbwerden zeigt Das Gelbwerden ist auf bestaunte Zusatzstoffe zurückzuführen, die bei der Herstellung der Kautschukmischungen standig verwendet werden, wie Beschleuniger und AntioxydationsmittelIt is known that the whitewall deteriorates with aging shows a more or less great tendency to yellowing. Yellowing is due to admired additives attributed to that in the manufacture rubber compounds are used all the time, such as accelerators and antioxidants
Diese das Gelbwerden fordernden Stoffe werden der Mischung, die zur Herstellung der Weißwand dient, nicht zugesetzt, aber sie sind in der Kaikassenmischung enthalten, die im fertigen Reifen mit der Weißwand in Berührung steht Mit der Zeit wandern diese Stoffe aus der Mischung der Karkasse in die Weißwand und bewirken das Gelbwerden derselbenThese yellowing substances are added to the mix used to make the whiteboard serves, not added, but they are in the quay mix included in the finished tire with the Whitewall in touch wander with time these substances from the mixture of the carcass into the white wall and cause the same to turn yellow
Man hat aus diesem Grunde zwischen der Karkasse und der Weißwand eine Zwischenschicht angeordnet, welche die Wanderung dieser Stoffe verhindert oder zumindest verzögertFor this reason, an intermediate layer has been placed between the carcass and the white wall, which prevents or at least delays the migration of these substances
Insbesondere ist es aus der USA-Patentschrift 2 240 855 bekannt, eine Zwischenschicht anzuordnen, die als die Wanderung verhindernden Stoff aktivierte Kohle enthaltIn particular, it is from the USA patent 2 240 855 known to place an intermediate layer which activated as a migration preventing substance Contains coal
Dieses Verfahren ist jedoch in der Praxis nur wenig angewendet worden, weil die fur die Zwischenschicht verwendeten Mischungen aus naturlichem Kautschuk, der aktivierte Kohle enthalt, nur geringe mechanische Eigenschaften aufweisen Bei diesen Mischungen ist nach einer gewissen Zeit ein Ablosen der Zwischenschicht zu beobachten, entweder von der Mischung der Karkasse oder von der Mischung der Weißwand, oder sogar ein Zerreißen im Inneren der Zwischenschicht Diese Zwischenschichten sind dabei fur die Herstellung von Weißwandreifen ungeeignet However, this procedure is only practical Little has been applied because that for the intermediate layer used mixtures of natural rubber, which contains activated carbon, only small show mechanical properties These mixtures become detached after a certain period of time of the intermediate layer, either from the carcass mix or from the mix the whiteboard, or even a tear inside the interlayer These interlayers are unsuitable for the production of whitewall tires
Gegenstand der Erfindung ist ein Weißwandreifen mit einer Aktivkohle enthaltenden Kautschukschicht zwischen Karkasse und Weiß wand, der daduich gekennzeichnet ist, daß der Kautschuk der Zwischenschicht zu 40 bis 85 Gewichtsprozent aus Polychloropren bestehtThe invention relates to a whitewall tire with a rubber layer containing activated carbon between the carcass and the white wall, which is marked by it is that the rubber of the intermediate layer consists of 40 to 85 percent by weight of polychloroprene consists
Vorzugsweise werden 50 und 70 Gewichtsprozent Polychloropren und aktivierte Kohle in Mengen von 17 bis 70 g, vorzugsweise 20 bis 60 g ]e Schicht der Karkasse und pro Quadratmeter der Zwischenschicht verwendet Eme derartige Zwischenschicht zeigt gute mechanische Eigenschaften, em gutes Anhaften an den Mischungen der Karkasse und der Weißwand und stellt em wirksames Hindernis fur die Wanderung der das Gelbwerden fordernden Stoffe darPreferably 50 and 70 weight percent polychloroprene and activated carbon are used in amounts of 17 to 70 g, preferably 20 to 60 g of the layer Carcass and per square meter of the intermediate layer used Eme such intermediate layer shows good mechanical properties, good adhesion to the carcass and whitewall compounds and represents an effective obstacle to the migration of substances that cause yellowing
Unter aktivierter Kohle ist Kohle zu verstehen, die durch Verkohlung tierischer oder pflanzlicher Produkte erhalten worden istActivated coal is understood to mean coal that has been obtained by charring animal or vegetable products
Gemäß der Erfindung werden die mechanischen WeißwandreifenAccording to the invention, the mechanical Whitewall tires

Eigenschaften einer vulkanisierten kautschukhaltigen Mischung, die zur Herstellung eines Weißwandreif ens verwendet wird, als gut bezeichnet, wenn die Reißfestigkeit einer solchen Mischung großer als kg/cm2 istProperties of a vulcanized rubber-containing mixture which is used for the production of a whitewall tire are designated as good when the tear strength of such a mixture is greater than kg / cm 2
Um die Funktion der Zwischenschicht als Hindernis fur die Wanderung der das Gelbwerden fordernden Stoffe beurteilen zu können, wurden zahlreiche Versuche angestellt, welche in der Herstellung von mit dieser Zwischenschicht versehenen Weißwandreifen und m der Beobachtung des Gelbwerdens der Weißwand nach bestimmten Zeiträumen bestehen, die von Monat bis 1 Jahr und mehr betrugenTo the function of the intermediate layer as an obstacle to the migration of the yellowing demanding To be able to assess substances, numerous attempts have been made, which in the production of with whitewall tires provided with this intermediate layer and the observation of the whitewall turning yellow exist after certain periods of time ranging from a month to 1 year and more
Um diese Funktion quantitativ beurteilen zu können, wurde auf folgende Weise verfahren.In order to be able to assess this function quantitatively, the following procedure was used.
Man hat fur jede Zwischenschicht em Muster hergestellt, das aus drei übereinanderliegenden Schichten bestandA pattern has been made for each intermediate layer, which consisted of three layers on top of each other
Die untere Schicht wurde aus emer bekannten Mischung hergestellt, die standig zum Überziehen der die Karkasse bildenden Schichten verwendet wird Diese Mischung enthalt die das Gelbwerden fordernden StoffeThe lower layer was known from emer Mixture produced which is constantly used to coat the layers that make up the carcass This mixture contains the substances that make it yellow

Die verwendete Mischung A hatte folgende Zusammensetzung The mixture A used had the following composition
GewichtsteileParts by weight
Die obere Schicht wurde aus emer Mischung hergestellt, die standig zur Herstellung der Weißwand selbst verwendet wirdThe top layer was made from a mixture which is constantly used to make the whiteboard itself
Die verwendete Mischung B hatte folgende Zusammensetzung The mixture B used had the following composition
Zwischen den beiden Schichten wird die Zwischenschicht angeordnet, die das Wandern der das Gelbwerden fordernden Stoffe verhindern soll. Dann wurde nach emer bestimmten Zeit mittels eines durch Reflexion wirkenden Spektralphotometers durch die Lichtstarke des reflektierten Lichts mit emer Wellenlange von 53 μ das Gelbwerden der Weißwand gemessen, indem als Stärke 100 die Starke des von einem Muster emer nicht gealterten Weißwand reflektierten Lichts genommen wurdeBetween the two layers is the intermediate layer arranged, which is to prevent the migration of the yellowing demanding substances. then was determined after a certain time by means of a reflection spectrophotometer due to the light intensity of the reflected light with a wavelength of 53 μ the yellowing of the Whitewall measured by adding 100 as the thickness of the whitewall that has not aged from a sample reflected light was taken
Die mit eimgen so ausgebildeten Mustern erzielten Ergebnisse sind in der nachstehenden Tabelle angegeben The ones obtained with some of the patterns designed in this way Results are given in the table below
Em Reifen gemäß der Erfindung ist m der Zeichnung dargestellt, die emen Querschnitt des Reifens veranschaulicht Die die Weißwand bildenden verschiedenen Schichten sind zwecks deutlicherer Darstellung voneinander abgelostEm tire according to the invention is m the drawing shown, the one cross-section of the tire illustrates the various that make up the whitewall Layers are detached from one another for the purpose of clearer representation
Der Reifen 1 besteht in ubhcher Weise aus derThe tire 1 consists of the
Karkasse 2, die aus emer bestimmten Anzahl von Schichten aus Reyongewebe gebildet ist, welche mit der oben als Mischung A bezeichneten Mischung überzogen sindCarcass 2, which is formed from a certain number of layers of rayon fabric, which with the mixture identified above as Mixture A are coated
Der Reifen weist außerdem zwei Wulste 3 und eine Laufflache 4 auf, die nicht genauer beschrieben werden, da sie nicht Gegenstand der Erfindung so sindThe tire also has two beads 3 and a tread 4, which are not described in more detail as they are not the subject of the invention
Auf einer Seitenfläche (oder gewünschtenfalls auf beiden Seitenflächen) des Reifens wird eine Weißwand 5 angebracht, die aus der oben beschriebenen Mischung B hergestellt worden ist Zwischen der Karkasse 2 und der Weißwand 5 wird jedoch eine Zwischenschicht 6 angeordnet, die aus emer Mischung gemäß der Erfindung hergestellt worden istA whitewall is placed on one side surface (or, if desired, on both side surfaces) of the tire 5 attached, which has been prepared from the mixture B described above Carcass 2 and the white wall 5, however, an intermediate layer 6 is arranged, which consists of a mixture has been made according to the invention
Die nachstehende Tabelle gibt die mechanischen Eigenschaften (Reißwiderstand und Modul bei 100%) der verschiedenen vulkanisierten Mischungen mit der angegebenen Zusammensetzung an Diese mechanischen Eigenschaften entsprechen dem Maximum der VulkanisierungskurveThe table below gives the mechanical properties (tear resistance and modulus 100%) of the various vulcanized compounds with the specified composition on these mechanical properties correspond to the maximum of the vulcanization curve
Die Tabelle zeigt auch das Maß des Gelbwerdens der Muster an Die Proben 1, 2 und 4 dienen zum VergleichThe table also shows the degree of yellowing of the samples. Samples 1, 2 and 4 are used for comparison
Aus der Tabelle ergibt sich, daß die Mischungen 1 und 2 — wie zu erwarten war — zwar das Gelbwerden verhindern, aber sehr geringe mechanische Eigenschaften aufweisen Hingegen ist festzustellen, daß die Mischung 3 gute mechanische Eigenschaften aufweist und gleichzeitig wirksam das Gelbwerden verhindert Die Mischung 5 laßt bereits em Abfallen der Reißfestigkeit erkennenThe table shows that mixtures 1 and 2 - as was to be expected - do indeed turn yellow prevent, but have very poor mechanical properties On the other hand, it can be stated that that the mixture 3 has good mechanical properties and at the same time effective yellowing The mixture 5 already shows a drop in tear strength
Die Mischung 4 weist eine der Mischung 3 analoge Zusammensetzung auf, es wurde jedoch die aktivierte Kohle durch eine gleiche Menge Ruß ersetzt von der Art, wie er standig m der Kautschukindustne verwendet wird Wenn auch die mechanischen Eigenschaften emer solchen Mischung sehr gut sind, hat sie andererseits praktisch keine Fähigkeit, das Gelbwerden der Weißwand zu verhindernThe mixture 4 has one of the mixture 3 analogous However, the activated carbon was replaced by an equal amount of carbon black from the composition Kind of constantly used in the rubber industry If the mechanical properties of such a mixture are very good they, on the other hand, have practically no ability to turn yellow to prevent the whitewall
