Description
Gegenstände oder Überzüge aus Kunstharz Die Erfindung bezieht sich auf die Herstellung von Gegenständen oder Überzügen aus Kunstharz nach dem Spritzverfahren. Die Verwendung von härtbaren Harzen, so z. B. Phenolaldehydharzen, mit entsprechenden Zusätzen zur Herstellung von Gegenständen nach dem Spritzverfahren ist schon vorgeschlagen worden. Sehr hinderlich wurde bei der Ausübung des Verfahrens die allzu schnelle Erhärtung des Materials empfunden.Resin Articles or Coatings The invention relates to on the production of objects or coatings from synthetic resin by the spraying process. The use of curable resins, e.g. B. phenol aldehyde resins, with appropriate Additives for the production of objects by the injection molding process have already been proposed been. The fact that the procedure was carried out too quickly became a major obstacle Perceived hardening of the material.
Es hat sich nun erfindungsgemäß gezeigt, daß man an Stelle der bisher benutzten Harze schmelzbare, härtbare Kondensationsprodukte aus primären aromatischen Aminen und Aldehyden für den genannten Zweck vorteilhaft verwenden kann, da die Kondensationsprodukte längere Zeit auf der zur Anwendung des Spritzverfahrens nötigen Temperatur, d. h. auf ungefähr tao bis Co'; ge= halten werden können, ohne daß sie ihre Konsistenz wesentlich ändern.It has now been shown according to the invention that instead of the previously used resins meltable, curable condensation products of primary aromatic Amines and aldehydes can be used advantageously for the purpose mentioned, since the Condensation products on the time required to use the spraying process Temperature, d. H. on about tao to co '; can be held without them change their consistency significantly.
Brauchbar für die Durchführung des neuen Verfahrens sind z. B. Harze, die in Gegenwart von aromatischen Säuren oder Säureanhydriden aus Anilin und Formaldehyd hergestellt sind (vgl. britische Patentschrift 388 o3o), oder auch solche Harze, bei denen in - Gegenwart von aliphatischen Carbonsäuren schmelzbare Kondensationsprodukte entstehen, wie sie in der schweizerischen Patentschrift 156761 beschrieben sind, oder weiterhin auch solche Harze, die in Gegenwart von bis zu einem Fünftel Äquivalent starker Mineralsäuren gemäß schweizerischer Patentschrift 165 84.o hergestellt «erden.Usable for the implementation of the new method are, for. B. Resins, those in the presence of aromatic acids or acid anhydrides from aniline and formaldehyde are manufactured (see British patent specification 388 o3o), or also such resins, where condensation products fusible in the presence of aliphatic carboxylic acids arise as they are described in the Swiss patent specification 156761, or continue to use those resins in the presence of up to one fifth equivalent strong mineral acids according to Swiss patent specification 165 84.o.
Die aus solchen schmelzbaren, härtbaren Harzen durch Spritzguß erzeugten Gegenstände sind von gleichmäßiger Beschaffenheit, besitzen eine hohe Eignung als elektrisches Isoliermaterial und sind den bisher bekannten nach einem Spritzverfahren hergestellten Kunstharzgegenständen überlegen.Those produced from such meltable, curable resins by injection molding Objects are of uniform texture and are highly suitable as electrical insulating material and are the previously known after a spraying process superior to manufactured resin objects.
An Stelle der reinen Kunstharze können auch Mischungen verwendet werden, die Weichmachungsmittel oder Füllmittel, wie Asbest bzw. Quarzmehl oder Kaolin, enthalten.Instead of pure synthetic resins, mixtures can also be used, the plasticizers or fillers, such as asbestos or quartz powder or kaolin, contain.
