Description

Es ist bereits bekannt, Reibungskörper aller Art, z. B. Bremsbeläge, dadurch herzustellen, daß man Faserstoffe, insbesondere Asbest usw., ferner Holzmehl, Korkmehl, mineralische Produkte usw. sowie Mischungen der genannten Stoffe mit Phenol-Aldehyd-Harzen der Resolklasse imprägniert, worauf dann unter Druck geformt und durch Erhitzen gehärtet wird. Ferner ist neuerdings vorgeschlagen, die Resolharze durch Gemische von Resinotannolharzen und Formaldehyd abgebenden Stoffen zu ersetzen, wobei auch natürliche und künstliche Harze zwecks Regtrlierung der Nachgiebigkeit mitverwendet werden können.It is already known to use friction bodies of all kinds, e.g. B. brake pads, thereby producing that one fiber, especially asbestos, etc., also wood flour, cork flour, mineral Products etc. as well as mixtures of the substances mentioned with phenol-aldehyde resins Resole class impregnated, whereupon molded under pressure and hardened by heating will. It has also recently been proposed that the resole resins be emitted by mixtures of resinotannol resins and formaldehyde Substances to replace, including natural and artificial resins for the purpose of regulation the flexibility can also be used.

Es hat sich nun ergeben, daß auch die Umwandlungsprodukte der Phthalsäure bzw. des Phthalsäureanhydrits mit Glycerin für den gedachten Zweck eine vorzügliche Eignung aufweisen, und zwar nicht nur für sich allein, sondern auch in Mischung mit anderen Harzprodukten, insbesondere auch z. B. Gemischen von Resinotannolharz und Formaldehyd abgebenden Stoffen. Durch Veränderung derIt has now been found that the conversion products of phthalic acid or des Phthalic anhydrits with glycerine are particularly suitable for the intended purpose, not only on its own, but also in combination with other resin products, in particular also z. B. Mixtures of resinotannol resin and formaldehyde donate Fabrics. By changing the

as Mengenverhältnisse zwischen Phthalsäure bzw. deren Anhydrid und Glycerin gelangt man zu Produkten von wechselnder Umwandlungsgeschwindigkeit, die auch zu verschieden harten Enderzeugnissen führen, was die Regulierung der jeweils gewünschten Nachgiebigkeit in leichter Weise erlaubt, ohne daß nachträgliche Änderungen, wie sie bei Anwendung von Resolharzen die Regel sind, befürchtet werden müßten. Es können alsoas proportions between phthalic acid or their anhydride and glycerine lead to products with changing conversion rates, which also lead to end products of different hardness, which regulates the flexibility desired in each case easily allowed without subsequent changes, as is the rule when using resol resins, should be feared. So it can

neben glasharten Erzeugnissen auch solche von ziemlicher Nachgiebigkeit gewonnen werden. Benutzt man nebenher härtbare Kombinationen anderer Art, so kann deren Härte gleichfalls durch die Phthalsäure-Glycerin-Produkte abgestimmt werden. Die Arbeitsweise ist die übliche. Man imprägniert also das zugrunde liegende Fasermaterial usw. mit einer Auflösung des .Phthalsäure-Glycerin-Harzes, verdampft das Lösungsmittel und formt schließlich unter Druck bei gleichzeitiger Anwendung von Hitze. Zwecks Abkürzung des Preßprozesses kann auch ohne Druck vorerhitzt werden, wobei man. Zeit und Temperatur so abstimmt, daß die für die Formung noch ausreichende Nachgiebigkeit erhalten bleibt.In addition to glass-hard products, products that are quite flexible can also be obtained. If other types of hardenable combinations are used at the same time, their hardness can also be achieved by the phthalic acid-glycerin products be matched. The way of working is the usual. So you impregnate the underlying fiber material, etc. with dissolution of the .phthalic acid-glycerol resin, the solvent evaporates and finally forms under pressure with simultaneous application of heat. For the sake of abbreviation of the pressing process can also be preheated without pressure, whereby one. Time and temperature coordinated so that that for the molding sufficient compliance is still retained.
