Description

Aus Schichten kunstharzgetränkter Faserstoffbahnen bestehende Schleifscheibe Die Erfindung betrifft eine Schleifscheibe, die aus Schichten kunstharzgetränkter Faserstoffbahnen besteht, auf die mittels einer Kunstharzbindung das Schleifkorn aufgebracht ist und die unter Druck und Hitze miteinander verpreßt sind. Man hat auch bereits vorgeschlagen, Kreppapier, das vor dem Auftragen der Schleifkörner mit Kunstharz getränkt worden ist, als Trägerunterlage für die Schleifkörner zu verwenden. Hier handelt es sich um ein Schleifpapier, dessen Kreppung deshalb vorgenommen wurde, um quer zu den Kreppfalten beim Arbeiten mit dem Schleifpapier eine höhere Geschmeidigkeit, Knitterfestigkeit und Dehnbarkeit zu erzielen, so daß es sich Unebenheiten und gewölbten Flächen von Werkstücken besser anpassen kann. Schließlich ist schon vorgeschlagen worden, als Material für Schichtschleifscheiben Lagen von Schleifpapier bzw. Schleifleinen zu verwenden.Sanding disc consisting of layers of synthetic resin-soaked fiber webs The invention relates to a grinding wheel made of layers of synthetic resin impregnated There is fibrous webs on which the abrasive grain is bonded by means of a synthetic resin bond is applied and which are pressed together under pressure and heat. One has also already suggested crepe paper that before applying the abrasive grains has been impregnated with synthetic resin as a backing for the abrasive grains use. This is a sandpaper, which is why it was creped was to get across the crepe folds when working with the sandpaper a higher To achieve suppleness, crease resistance and elasticity, so that there are bumps and curved surfaces of workpieces can better adapt. Finally is already has been proposed as a material for laminated grinding wheels, layers of sandpaper or abrasive cloth to be used.

Hier knüpft die Erfindung an, derzufolge die Schleifscheibe aus Faserstoffbahnen besteht, die zur Erhöhung ihrer Saug- und Tränkfähigkeit gebrochen oder gekreppt sind.This is where the invention ties in, according to which the grinding wheel is made from fibrous webs exists that are broken or creped to increase their absorbency and soakability are.

Während bisher für Schichtschleifscheiben nur glatte Faserstoffbahnen Verwendung fanden, werden durch das Kreppen oder Brechen die aus Faserstoffbahnen hergestellten Schichten für die Kunstharzlösung noch aufnahmefähiger, so daß sich eine noch innigere Verbindung der Schleifkornunterlagen untereinander, des Bindemittels mit den Bahnen und des Schleifmittels ergibt, als es bei glatten ungekreppten Faserstoffbahnen möglich ist.While so far only smooth fibrous webs have been used for layered grinding wheels They are used by creping or breaking the fibrous webs Produced layers for the synthetic resin solution even more receptive, so that themselves an even more intimate connection between the abrasive grain supports, the binding agent with the webs and the abrasive than it does with smooth uncreped fibrous webs is possible.

Die gekreppte oder gebrochene Unterlage aus Faserstoffen wird dann mit einer härtenden Kunstharzlösung oder Kunstharzemulsion getränkt und getrocknet.The creped or broken fibrous backing is then soaked with a hardening synthetic resin solution or synthetic resin emulsion and dried.

Auf einer Seite der gebrochenen Unterlage wird anschließend eine Schicht des Kunstharzklebstoffes aufgetragen und die Schleifkörner aufgestreut. Die so gewonnenen Schleifschichten werden anschließend nach dem bei 6o° C erfolgten Trocknen in Scheiben oder andere Formen gestanzt, die dann als Platten oder in Preßform zu Schleifkörnern unter Druck bei einer Härtetemperatur von etwa I4o bis I8o° C durch Pressen zusammengefügt werden, und zwar je nach Härte 5 bis 2o Minuten lang.A layer is then applied to one side of the broken base of the synthetic resin adhesive applied and the abrasive grains sprinkled on. The ones won in this way Abrasive layers are then cut into discs after drying at 60 ° C or punched in other shapes, which are then used as plates or in compression form to produce abrasive grains Pressed together under pressure at a hardening temperature of around 14o to 18o ° C for 5 to 20 minutes, depending on the hardness.

So hergestellte Schleifscheiben sind gegenüber den bisher üblichen keramischen Schleifscheiben schnell und billig zu erzeugen und können als Trenn- und Flächenschleifscheiben verwendet werden. Der Vorteil dieser Scheiben gegenüber den bisher verwandten Scheiben für den gleichen Zweck liegt in der elastischen Ausführung und in der hohen Festigkeit. Die Brechung oder Kreppung der Unterlagestoffe macht es möglich, dieselben mit Klebstoffen besser zu durchtränken und beim Pressen die Körner und die einzelnen Schichtscheiben intensiver und inniger zu einem Körper zu formen, als es bei Verwendung ungekreppten Schichtmaterials möglich ist.Grinding wheels produced in this way are compared to the previously common ones ceramic grinding wheels can be produced quickly and cheaply and can be used as cutting and surface grinding wheels can be used. The advantage over these discs the previously used washers for the same purpose lies in the elastic design and in high strength. The breaking or creping of the base material makes it is possible to soak them better with glue and when pressing the Grains and the individual layer discs more intensely and intimately into one body than is possible when using uncreped sheet material.
