Abstract
Description
Die Erfindung betrifft eine helle Mischung auf Elastomerbasis für Räder und Rollen, insbesondere zur Verwendung im medizinischen Bereich, wobei die Mischung zumindest einen mit Schwefel oder mit Schwefelspender vernetzbaren Kautschuk oder Verschnitte aus Kautschuk und einem thermoplastischen Elastomer sowie einen hellen Füllstoff und übliche Verarbeitungshilfen enthält.The invention relates to a light mixture Elastomer base for wheels and rollers, in particular for Use in the medical field, with the mixture at least one with sulfur or sulfur donor crosslinkable rubber or blends of rubber and a thermoplastic elastomer and a bright Contains filler and common processing aids.
Es sind helle Mischungen für Räder und Rollen auf Elastomerbasis wie auch auf Kunststoffbasis im medizinischen Bereich bekannt. Es sind weiterhin Mischungen mit rußgefüllten Elastomeren bekannt, die jedoch in den schmutzempfindlichen Bereichen zu erheblichen Reinigungsproblemen führen. Mit einer hellen Mischung verhindert man ein sogenanntes Abkreiden, zum anderen weist sie ein günstigeres Kontaktverfärbungs verhalten auf.There are bright blends for wheels and wheels on Elastomer base as well as on plastic basis in known medical field. It is still Mixtures with carbon black-filled elastomers known, the however, in the dirt sensitive areas too lead to significant cleaning problems. With a bright Mixture prevents a so-called chalking, for Others, it has a better contact discoloration behave on.
Der Erfindung liegt die Aufgabe zugrunde, eine eingangs genannte Mischung anzugeben, die sich darüber hinaus durch eine relativ hohe Leitfähigkeit auszeichnet.The invention is based on the object, an input specify the mixture mentioned above a relatively high conductivity is characterized.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Mischung zur Erhöhung der Leitfähigkeit in einem Anteil von zumindest 3 Vol.-% Kurzschnittfasern aus Kohlenstoff und/oder Stahl enthält, die dem Rad oder der Rolle einen Ableitwiderstand von <104Ω verleihen.This object is achieved in that the mixture to increase the conductivity in a proportion of at least 3 vol .-% short cut fibers made of carbon and / or steel, which give the wheel or the role of a discharge resistance of <10 4 Ω.
Mit der Erfindung erzielt man den Vorteil, daß auf schmutzempfindlichen Böden der Reinigungsaufwand durch Verwendung der nichtkreidenden antistatisch wirksamen Mischung erheblich reduziert wird. Gleichzeitig erhält man eine "leitfähige" Mischung im Sinne der DIN-Norm IEC 601 Teil 1.With the invention provides the advantage that on dirt-sensitive floors of the cleaning effort by Use of non-chilling antistatic agents Mixture is significantly reduced. At the same time you get a "conductive" mixture in the sense of the DIN standard IEC 601 Part 1.
Nach einer vorteilhaften Ausgestaltung der Erfindung liegen die Fasern in einem Längenbereich von 0,1 bis 15 mm, bevorzugt in einem solchen von 0,1 bis 7 mm. Ein vorteilhaftes Ausführungsbeispiel der Erfindung zeichnet sich dadurch aus, daß als Elastomer ausschließlich Naturkautschuk zur Anwendung gelangt. Um optischen Wünschen gerecht zu werden, können der Mischung ein oder mehrere Farbstoffe zugefügt sein.According to an advantageous embodiment of the invention the fibers are in a length range of 0.1 to 15 mm, preferably in such a range of 0.1 to 7 mm. On advantageous embodiment of the invention is characterized characterized in that as the elastomer exclusively Natural rubber is used. To optical To meet wishes, one or the mixture can several dyes added.
Nachfolgend werden drei Beispiele der Mischung
dargestellt, wobei im ersten Beispiel als Elastomer
ausschließlich Naturkautschuk vorkommt, während im zweiten
und dritten Beispiel ein Verschnitt aus Naturkautschuk und
einem thermoplastischen Elastomer vorliegt. Im ersten
Beispiel kommt ein Gemisch aus Kurzschnitt-Stahlfasern und
Kurzschnitt-Kohlefasern zum Einsatz, im zweiten Beispiel
sind ausschließlich Kurzschnitt-Kohlefasern enthalten, im
dritten dagegen ausschließlich Kurzschnitt-Stahlfasern.
In the following, three examples of the mixture are shown, wherein in the first example only natural rubber occurs as the elastomer, while in the second and third examples a blend of natural rubber and a thermoplastic elastomer is present. In the first example, a mixture of short cut steel fibers and short cut carbon fibers is used, in the second example only short cut carbon fibers are included, in the third only short cut steel fibers.
