Schleifbänder

B.Beispiel :. Auf nicht vorbehandeltes Köpergewebe wird eine Mischung bestehend aus
EMI2.1
<tb>
<tb> 35 <SEP> Teilen <SEP> Polyamidaminen <SEP> auf <SEP> Basis <SEP> von <SEP> vornehmlich
<tb> dimerisierten <SEP> Fettsäuren,
<tb> 65 <SEP> Teilen <SEP> Epoxyharz <SEP> und <SEP>
<tb> 21o <SEP> Dicyandiamid <SEP> (bezogen <SEP> Auf <SEP> die <SEP> Gesamtmischung
<tb> ohne <SEP> Lösungsmittel) <SEP> und
<tb> 2o <SEP> Lösungsmittelgemisch <SEP> aus <SEP> ToluoI/Xylol <SEP> im <SEP> Verhältnis <SEP> 1 <SEP> : <SEP> 9
<tb>
durch Walzen aufgetragen. Das Schleifkorn wird nun aufgeschütter und der Uberschuss durch Rütteln wieder entfernt. Die Härtung erfolgt bei einer Temperatur von zirka 1200 C, wobei eine feste Verbindung zwischen Korundkorn und Oberfläche des Köpergewebes entsteht.
Nach der Aushärtung wird aus der gleichen vorhin beschriebenen Mischung in stark verdünnter Lösung (60 - 70% Lösungsmittelgemisch) durch Filzwalzen eine dünne Deckschicht aufgetragen und ebenfalls bei zirka 1200 C eingebrannt. Die Bahnen werden nun in beliebige Streifen geschnitten und über einer besonderen Vorrichtung geflechst. Zum Schluss erfolgt die Verklebung zu endlosen Bändern.
PATENTANSPRÜCHE :
1. Schleifbänder, dadurch gekennzeichnet, dass die Schleifkörper mittels Epoxyharz, das mit Poly- amidoaminen, vornehmlich auf Basis di-oder trimerlsierter Fettsauren gehärtet ist, mit der Unterlage fest verbunden sind.

<Desc / Clms Page number 2>
B. Example:. A mixture consisting of
EMI2.1
<tb>
<tb> 35 <SEP> Divide <SEP> polyamide amines <SEP> on <SEP> basis <SEP> by <SEP> mainly
<tb> dimerized <SEP> fatty acids,
<tb> 65 <SEP> parts <SEP> epoxy resin <SEP> and <SEP>
<tb> 21o <SEP> Dicyandiamid <SEP> (related to <SEP> <SEP> the <SEP> total mixture
<tb> without <SEP> solvent) <SEP> and
<tb> 2o <SEP> solvent mixture <SEP> made of <SEP> toluene / xylene <SEP> in the <SEP> ratio <SEP> 1 <SEP>: <SEP> 9
<tb>
applied by rolling. The abrasive grain is now shaken up and the excess is removed again by shaking. The hardening takes place at a temperature of around 1200 C, whereby a firm connection between the corundum grain and the surface of the body fabric is created.
After curing, a thin top layer is applied from the same mixture described above in a very dilute solution (60-70% solvent mixture) using felt rollers and also baked at about 1200 C. The strips are then cut into any strips and braided over a special device. Finally, the gluing takes place to form endless bands.
PATENT CLAIMS:
1. Abrasive belts, characterized in that the abrasive bodies are firmly connected to the base by means of epoxy resin which is hardened with polyamidoamines, primarily based on di- or trimerized fatty acids.
