Die Erfindung betrifft ein Verfahren zur Herstellung von Schleifartikeln, bei dem man auf ein Trägermaterial eine Mischung aus härtbaren Harzen und Schleifmitteln aufbringt und aushärtet.The invention relates to a method of manufacture of abrasive articles, in which a mixture of hardenable resins and Applies and hardens abrasives. Nach der Erfindung wird als Trägermaterial ein verfestigtes Nadelfilz aus groben Polyamidfasern verwendet, bei dem die Fasern mikrofein durch Anlösen miteiander verbunden sind, indem sie mit einer p-Oxy- ;t benzoesäureoctylesterlösung oder p-Oxybenzoesäureoctylesteremulsion benetzt und bei 100 bis 160°C verschweißt worden sind; als Schleifmittel werden Korund oder Siliciumcarbid verwendet.According to the invention, a consolidated needle felt made of coarse polyamide fibers is used as the carrier material, in which the fibers are connected to one another in a microfine manner by loosening them by being connected to a p-oxy-; t octyl benzoate solution or octyl p-oxybenzoate emulsion have been wetted and welded at 100 to 160 ° C; corundum is used as an abrasive or silicon carbide is used. Es ist zwar bei der Herstellung von Faservliesen bekannt, die Vliese mit Bindemitteln zu durchtränken oder zu besprühen, wobei das Bindemittel in das Vlies eingelagert wird, um die erforderliche Verfestigung des Faservlieses durch Verkleben der Fasern zu erreichen, was erfindungsgemäß nicht notwendig, ja sogar nicht erwünscht ist. Als härtbare Harze eignen sich besonders Phenolharze. Als Schleifmittel eignen sich Korund oder Siliciumcarbid. Der so hergestellte Schhifartikel ist im Gegensatz zu den bekannten Schleifartikeln außerordentlich widerstandsfähig.It is known in the production of fiber webs to impregnate the webs with binders or spray, the binder in the fleece is stored in order to achieve the necessary consolidation of the fiber fleece by gluing the fibers, which according to the invention is not necessary, indeed not even desirable. Suitable as curable resins especially phenolic resins. Corundum or silicon carbide are suitable as abrasives. The one made in this way In contrast to the known abrasive articles, abrasive articles are extremely resistant. Es ist auch bekannt, Harz-Schleifmittelmischungen auf Träger wie Papier, Gewebe oder Vlies aufzutragen. Es hat sich aber gezeigt, daß die Träger Papier und Gewebe, die fast eine geschlossene Oberfläche aufweisen, wenig elastisch sind und den Schleif staub nicht in sich aufnehmen können. Dadurch neigen sie zu einem schnelleren Verschleiß. Auch bei einem Schleifartikel, der sich auf einem Trägervlies aufbaut, ist — festzustellen, daß die Gebrauchstüchtigkeit noch nicht erhöhten Anforderungen genügt.It is also known to apply resin-abrasive mixtures to substrates such as paper, woven fabric or non-woven fabric. However, it has been shown that the carrier paper and fabric, which have an almost closed surface, are not very elastic and cannot absorb the sanding dust. As a result, they tend to faster wear. Even with an abrasive article that builds up on a backing fleece - determine that the fitness for use does not yet meet increased requirements. Die Erfindung hat gegenüber den bekannten Schleifartikeln den Vorteil, durch den strukturellen Aufbau des Nadelfilzes höchsten Anforderungen z. B. Reißfestigkeit, Abriebfestigkeit, Lösungsmittelbeständigkeit, Kochfestigkeit usw. zu genügen.The invention has the advantage over the known abrasive articles by the structural Structure of the needle felt highest requirements z. B. tear resistance, abrasion resistance, solvent resistance, Boil resistance, etc. to be sufficient. Aus diesem nach dem beschriebenen Verfahren hergestellten Endprodukt können Formschleifstücke wie z. B. Platten, Scheiben, Rollen, Würfel, Handschuhe u. dgl. gefaltet, gestanzt, geschnitten, genäht, geschweißt und sonstwie hergestellt werden.From this end product produced by the process described, shaped grinding pieces can be made such as B. Plates, discs, rolls, cubes, gloves and the like. Folded, punched, cut, sewn, welded and otherwise manufactured. Beispielexample Ein Kreuz- bzw. Wirrfaservlies aus 100 % Polyamidfasern 30 den und 80 mm Schnittlänge wird auf einem Nadelstuhl zwecks Vorverfestigung genadelt und anschließend mit einer p-Oxybenzoesäureoctylesterlösung oder -emulsion benetzt. Die hierbei angelösten Fasern werden bei 100 bis 16O0C mikrofein an ihren Kreuzungspunkten miteiander verschweißt. Ein solches Nadelfilz wird mit einer Mischung von 50 Teilen Phenolharz und 50 Teilen Siliciumcarbit — Körnung 80 bis 100 μ — oder Korund oberflächlich besprüht, dann getrocknet und bei 13O0C 30 Minuten gehärtet.A cross or random fiber fleece made of 100% polyamide fibers 30 denier and 80 mm cut length is needled on a needle loom for pre-consolidation and then wetted with an octyl p-oxybenzoate solution or emulsion. The hereby partially dissolved fibers are welded at 100 to 16O 0 C microfine at their crossing points miteiander. Such a needle felt is treated with a mixture of 50 parts phenolic resin and 50 parts of silicon carbide - sprayed superficial or corundum, cured for 30 minutes and then dried at 13O 0 C - grain size 80 to 100 μ. ■' Patentanspruch:■ 'Claim: Verfahren zur Herstellung von Schleifartikeln, wobei man auf ein Trägermaterial eine Mischung aus härtbaren Harzen und Schleifmitteln aufbringt und aushärtet, d adurch g e'k ennzeichnet, daß man als Trägermaterial ein verfestigtes Nadelfilz aus groben Polyamidfasern- verwendet, bei dem die Fasern mikrofein durch Anlösen miteinander verbunden sind, indem sie mit einer p-Oxybenzoesäureoctylesterlösung oder p-Oxybenzoesäureoctylesteremulsioh benetzt und bei 100 bis 16O0C verschweißt worden sind, und daß man als Schleifmittel Korund oder Siliciumcarbid verwendet.Process for the production of abrasive articles, in which a mixture of curable resins and abrasives is applied to a carrier material and cured, characterized by the fact that a consolidated needle felt made of coarse polyamide fibers is used as the carrier material, in which the fibers are microfine by dissolving are connected to each other by being wetted with a p-type or p-Oxybenzoesäureoctylesterlösung Oxybenzoesäureoctylesteremulsioh and welded at 100 to 16O 0 C, and that there is used as an abrasive corundum or silicon carbide.
