Description

Verfahren zur Herstellung von Preßkörpern Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Preßkörpern aus härtbarem Kunstharz.Process for the production of pressed bodies The subject of the invention is a process for the production of compacts from curable synthetic resin.

Es ist bekannt, zur Herstellung von Kunstharzpreßkörpern insbesondere Holzmehl oder Asbest als Füllstoff zu verwenden. Aucli hat man schon vorgeschlagen, Ton als Füllstoff zu gebrauchen. Es zeigt sich jedoch, daß Ton nur in gebranntem Zustand verwendbar ist, da ungebrännte, nur getrocknete Tone den Nachteil hervorrufen, daß, die damit hergestellten Preßkörper an den Formen kleben und leicht Wasser aufnehmen. Die gebrannten Tone sind aber zur Erzeugung von billigen Preßgegenständen wenig wirtschaftlich.It is known in particular for the production of synthetic resin molded bodies Use wood flour or asbestos as a filler. Aucli has already been suggested To use clay as a filler. It turns out, however, that clay can only be found in fired Condition is usable, since unbaked, only dried clays cause the disadvantage, that the compacts produced with it stick to the molds and easily absorb water. The fired clays are, however, not very useful for the production of cheap pressed articles economically.

Es wurde nun gefunden, daß man auch ungebrannten, nur getrockneten Ton als Füllstoff für Kunstharzpreßkörper verwenden kann, wenn man dem Gemisch von lufttrockenem Ton und härtbarem -Kunstharz etwas Holzöl, dem eine sehr geringe Menge Jod zugesetzt ist, zugibt. Es ist zwar schon. bekannt, den Kunstharzpreßmischungen schmierend wirkende Stoffe, wie z. B. öle, Wachse, fettsaure Salze usw:, zuzusetzen, um das Ankleben der Preßkörper a den Formen zu verhindern. Bei dem vorliegenden Verfahren wird aber nicht nur das Ankleben des Preßkörpers verhindert, sondern @es wird auch noch durch die Polymerisation des Holzöles infolge des Zusatzes von Jod die ölige Hülle des Preßkörpers verfestigt und so der Körper in seinen Eigenschaften verbessert, insbesondere seine Wasseraufnahme wesentlich herabgesetzt. Dies ist besonders bei der Herstellung von elektrischen Isoliierlz:#örpern wichtig. Ferner ist die Elastizität der Preßkörper vergrößert. , Beispielsweise vermischt man 8o Gewichtsteile pulverisierten lufttrockenen Ton mit 18 Gewichtsteilen pulverisiertem härtbarem P'henolaldehydharz und z Gewichtsteilen Holzöl, dem einige Tropfen Jodtinktur zugesetzt .sind. Dabei gibt man sauf io ccm Holzöl etwa 3 Tfopfen der Jodtinktur (r:zo). Die Mischung wird in üblicher Weise heiß verpreßt.It has now been found that you can also use unfired, only dried Clay can be used as a filler for synthetic resin compacts if the mixture of air-dry clay and hardenable synthetic resin some wood oil, to which a very small amount Iodine is added, admits. It is true. known, the Kunstharzpreßmischungen substances with a lubricating effect, such as B. oils, waxes, fatty acid salts, etc., add, to prevent the compacts from sticking to the molds. With this one Process is not only prevented from sticking of the pressed body, but @es is also due to the polymerisation of the wood oil as a result of the addition of iodine the oily shell of the pressed body solidifies and so the body in its properties improved, in particular its water absorption significantly reduced. This is especially important in the manufacture of electrical insulation bodies. Further the elasticity of the pressed body is increased. For example, one mixes 8o Parts by weight of powdered air-dry clay with 18 parts by weight of powdered hardenable phenol aldehyde resin and z parts by weight of wood oil with a few drops of iodine tincture are added. To do this, add about 3 pots of iodine tincture to 10 cc of wood oil (r: zo). The mixture is hot-pressed in the usual way.

PATENTANSPRUCH: Verfahren zur Herstellung von Preßkörpern mit Kunstharz als Bindemittel und Ton als Füllstoff, dadurch gekennzeichnet, daß man lufttrockenen Ton, härtbares Kunstharz und etwas Holzöl, dem eine sehr geringe Menge Jod zugesetzt ist, innig vermischt und heiß verpreßt. PATENT CLAIM: Process for the production of pressed bodies with synthetic resin as binder and clay as filler, characterized in that air-dry clay, hardenable synthetic resin and some wood oil to which a very small amount of iodine is added, intimately mixed and hot-pressed.
