Abstract
Description
Die Erfindung betrifft eine Kautschukmischung zur Herstellung von Schleif- und Polierscheiben.The invention relates to a rubber mixture for the production of grinding and polishing wheels.
Fertigungsverfahren zur formgebenden Bearbeitung von Werkstoffen verursachen als unerwünschtes Bearbeitungsergebnis Grate. Diese Werkstoffanhäufungen liegen oberhalb der Sollgeometrie des Werkstückes und befinden sich an dessen Kanten oder Oberflächen. Die Beschaffenheit der Oberfläche ist von ausschlaggebender Bedeutung für die Güte des Werkstückes. Ebenso wichtig wie der Vorgang beim Schleifen ist der Poliervorgang.Manufacturing processes for shaping materials cause as undesirable machining result burrs. These material accumulations are above the Target geometry of the workpiece and are located on its edges or surfaces. The The quality of the surface is of crucial importance for the quality of the Workpiece. The polishing process is just as important as the grinding process.
Bekannt sind Schleifkörper, die durch Vermischen von Schleifkorn mit einem Bindemittel, bei dem es sich um ein schmelzbares Kunstharzpulver handelt, durch Verhärten des Bindemittels hergestellt werden. Der Nachteil dieser Schleifkörper besteht darin, daß kein genügendes elastisches Verhalten im Anwendungsfall sowie eine mangelhafte Ölbeständigkeit vorhanden ist. Die beim Schleifen eingesetzten Kühlschmiermittel enthalten in den meisten Fällen Öle oder ölähnliche Substanzen in dispergierter Form.Abrasives are known which are obtained by mixing abrasive grain with a binder which is a meltable synthetic resin powder by hardening the binder getting produced. The disadvantage of this grinding wheel is that it is not sufficient elastic behavior in the application and poor oil resistance. In most cases, the cooling lubricants used in grinding contain oils or oil-like substances in dispersed form.
Dagegen zeigt die erfindungsgemäße Kautschukmischung in einer Zusammensetzung gemäß Kennzeichen des Anspruchs 1, insbesondere gemäß Kennzeichen des Anspruchs 2, ein elastisches Verhalten und die erforderliche Ölbeständigkeit. Die Einsatzgebiete liegen vor allem ihrer Elastizität wegen überall dort, wo man mit herkömmlichen Schleifscheiben auf Kunstharzbasis schwer an zugängliche Werkstückformen herankommt.In contrast, the rubber mixture according to the invention shows in a composition according to Characteristics of claim 1, in particular according to the characteristics of claim 2 elastic behavior and the required oil resistance. The areas of application are primarily Because of their elasticity, wherever you can use conventional grinding wheels Resin base difficult to get to accessible workpiece shapes.
Folgende Vorteile weisen die elastischen Schleif- und Polierscheiben auf der Basis der erfindungsgemäßen Zusammensetzung auf:The elastic grinding and polishing discs based on the have the following advantages composition according to the invention on:
- - besonders anschmiegsam- particularly cuddly
- - feinste Oberfläche in kürzester Bearbeitungszeit;- finest surface in shortest processing time;
- - Ölbeständigkeit gegenüber Kühlschmiermittel;- Oil resistance to cooling lubricants;
- - gute Kornhaftung;- good grain adhesion;
- - hohe Standzeit;- long service life;
- - geringer Abrieb (Abrasion).- low abrasion.
Als Schleifkorn können sämtliche Schleifkornarten, insbesondere Quarze, Korunde oder Carbide, insbesondere wiederum Siliziumcarbide, eingesetzt werden. Je nach Anwendungsfall der Schleifkörper ist der Einsatz von Schleifkörnern in der Korngröße F 8 bis F 1200 (nach FEPA- Norm), insbesondere von F 60 bis F 360, vorgesehen. Mit dem Einsatz eines Verstärkerharzes werden im Verbund mit dem eigentlichen Verstärkungsmittel, dem Schleifkorn bzw. Schleifkornaddukt, vorteilhafte Härtegrade erzielt. Das Verstärkerharz, beispielsweise auf der Basis von Phenol oder eines substituierten Phenols, wird parallel zur Schwefelvulkanisation vernetzt. Weiterhin wird die Einmischbarkeit sowie die Dispergierbarkeit des Schleifkorns bzw. des Schleifkornadduktes in der Polymermatrix in Gegenwart eines Verstärkerharzes wesentliche verbessert.All types of abrasive grain, in particular quartz, corundum or carbide, in particular silicon carbides are used. Depending on the application Abrasives are the use of abrasive grains in the grain size F 8 to F 1200 (according to FEPA- Standard), in particular from F 60 to F 360. With the use of a reinforcing resin are combined with the actual reinforcement, the abrasive grain or Abrasive grain adduct, advantageous degrees of hardness achieved. The reinforcing resin, for example on the The base of phenol or a substituted phenol is used in parallel to the sulfur vulcanization networked. Furthermore, the miscibility and dispersibility of the abrasive grain or of the abrasive grain adduct in the polymer matrix in the presence of a reinforcing resin essential improved.
Zweckmäßigerweise wird ein Schleifkornaddukt, insbesondere ein Siliziumcarbidaddukt verwendet, das einen Aktivator, insbesondere ein Silan, enthält. Auf diese Weise kann die Kornhaftung zum Kautschuk verbessert werden. Der Beladungsgrad des Aktivators bzw. des Silanes beträgt dabei vorteilhafterweise 2 bis 25 Gew.-%, und zwar bezogen auf das Schleifkornaddukt.An abrasive grain adduct, in particular a silicon carbide adduct, is expediently used used, which contains an activator, in particular a silane. In this way, the Grain adhesion to the rubber can be improved. The degree of loading of the activator or Silanes is advantageously 2 to 25 wt .-%, based on that Abrasive grain adduct.
