Description

Verfahren zur Herstellung von härtbaren harzartigen Kondensationsprodukten Die Erfindung beruht auf der Wahrnehmung, daß man die nach den Patentschriften 335 984 und 317 267 in bekannter Weise gewonnenen, nicht härtbaren Anhydroformaldehydanilinharze mit härtbaren Kondensationsprodukten aus Phenolen und Formaldehyd bzw. mit den bekannten härtbaren Kondensationsprodukten aus Resinotannolharzen und Formaldehyd vereinigen kann und auf diese Weise mehr oder weniger harte Massen erhält.Process for the preparation of curable resinous condensation products The invention is based on the perception that the non-curable anhydroformaldehyde aniline resins obtained in a known manner according to patents 335 984 and 317 267 with curable condensation products of phenols and formaldehyde or with the known curable condensation products of resinotannol resins and Can combine formaldehyde and thus obtain more or less hard masses.

Die rot gefärbten hochglänzenden hartgummiähnlichen Harzprodukte widerstehen chemischen Einflüssen in höchstem Maße. Sie können für sich allein oder mit organischen und anorganischen Füllstoffen vereinigt zu Preßkörpern aller Art verarbeitet werden, wobei die Härtung unter Erhitzung gegebenenfalls unter gleichzeitiger Formgebung durch Druck erfolgen kann.The red colored high gloss hard rubber-like resin products resist chemical influences to the highest degree. You can do it on your own or with organic and inorganic fillers are combined to form all kinds of compacts, wherein the hardening with heating, optionally with simultaneous shaping can be done by pressure.

Während sowohl reine Phenolformaldehydkondensationsprodukte als auch reine Resinotannolformaldehvdharze unter Ablauf einer raschen und mitunter stürmischen Reaktion bei Hitzeeinwirkung zu festen Massen erstarren, wird durch die Zugabe kleinerer oder größerer Mengen von Anhydroformaldehydanilinharzen der Eintritt der endgültigen Härtung kürzere oder längere Zeit verzögert. Dies bedeutet einen technischen Vorteil in allen den Fällen, wo ein längeres Flüssigbleiben der Harzmasse während der Einwirkung von Druck und Hitze erforderlich ist, so z. B. wenn die Harzmasse trockene Füllstoffe durchdringen muß, mit denen sie in gepulvertem Zustand nur mechanisch vermengt war, oder wenn die Masse in hohen Preßformen allmählich aufwärts steigen und feinere Gravierungen oder netzartige Durchbrechungen ausfüllen soll.While both pure phenol-formaldehyde condensation products and pure Resinotannolformaldehvdharze under the expiry of a rapid and sometimes stormy The reaction solidifies to solid masses when exposed to heat, becomes smaller with the addition or larger amounts of anhydroformaldehyde aniline resins the entry of the final Curing delayed for a shorter or longer period of time. This means a technical advantage in all cases where the resin composition remains fluid for a long time during exposure pressure and heat is required, e.g. B. when the resin composition has dry fillers must penetrate, with which it was only mechanically mixed in the powdered state, or when the mass gradually rises and finer in high molds To fill in engravings or mesh-like openings.

Ein solcher Effekt wird durch den bekannten Zusatz von Anhydroformaldehydanilin zu Resolen nicht erreicht. Vielmehr erhält man nach diesem auf eine Erhöhung der Härtegeschwindigkeit des Resols abzielenden Verfahren beim Verpressen mit Füllstoffen blasige Produkte, während man nach der vorliegenden Arbeitsweise unter den gleichen Bedingungen zu homogenen Preßstücken gelangt.Such an effect is caused by the known addition of anhydroformaldehyde aniline to resoles not achieved. Rather, one gets after this on an increase in the Method aimed at hardening the resole when grouting with fillers blistered products, while following the present procedure under the same Conditions reached homogeneous pressed pieces.

Beispiel i 2o Teile Anhydroformaldehydanilinharz 3o Teile Resinotannolformaldehydharz und 5o Teile Phenolformaldehydharz ioo Teile werden durch Verschmelzen oder gemeinsames Lösen vereinigt. Das Gemisch kann für sich allein oder mit anorganischen und organischen Füll- und Faserstoffen, wie Sch-,verspat, Asbest, Sägemehl u. dgl., vereinigt und durch weiteres Erhitzen mit oder ohne Druck in eine honnogene blasenfreie äußerst harte, unlösliche und unschmelzbare Masse übergeführt werden.Example i 2o parts of anhydroformaldehyde aniline resin 3o parts resinotannol formaldehyde resin and 50 parts phenol-formaldehyde resin ioo parts are made by fusing or common loosening united. The mixture can be used on its own or with inorganic and organic fillers and fibers, such as Sch, verspat, asbestos, sawdust and the like. Combined and by further heating with or without pressure into a homogeneous, bubble-free, extremely hard, insoluble and infusible mass be transferred.

Beispiel e 2o Teile Anhydroformaldehydanilinharz und 8o Teile Resolharz i oo Teile werden nach Beispiel i vereinigt und weiterbehandelt. Beispiel-3 2o Teile Anhydroformaldehydanilinharz und 8o Teile Resinotannolformaldehydharz (hergestellt durch Behandeln von Akaroid mit Formaldehyd) ioo Teile werden nach Beispiel i und :2 ver- arbeitet, - Example e 2o parts of anhydroformaldehyde aniline resin and 8o parts of resole resin i oo parts are combined according to example i and treated further. Example-3 2o parts of anhydroformaldehyde aniline resin and 8o parts resinotannol formaldehyde resin (made by treating Acaroid with formaldehyde) 100 parts are made according to example i and: 2 is working, -
