Description

Verfahren zur Herstellung von Kunstmassen. Bekanntlich verwendet man in ,der Technik Kondensationsprodukte der Phenole mit Aldehyden entweder allein oder indem man diese Produkte mit verschiedenen Stoffen, wie z. B. Kaolin, Asbest, Graphit, Sägemehl, Papier, Zellulose usw., füllt und dann pneßt.Process for the production of artificial masses. As is well known, one uses in, engineering condensation products of phenols with aldehydes either alone or by combining these products with various substances, such as B. kaolin, asbestos, Graphite, sawdust, paper, cellulose, etc., fills and then presses.

Von allen diesen Füllmitteln kommt die Zellulose besonders in Betracht, weil die Gegenstände dadurch hochdielektrische Eigenschaften annehmen sowie leicht und dauerhaft werden.Of all these fillers, cellulose is particularly suitable, because the objects thereby take on high dielectric properties and light and become permanent.

Papier, Holzmasse oder Zellulose in die Kondensationsprodukte einzuführen, ist zwar ziemlich schwierig, doch gelingt es für flüssige Produkte die heiß gepreßt werden, bei Verwendung besonderer Apparate; für gegossene Produkte dagegen ist dies nicht möglich, da die flüssige Masse durch mehr oder weniger grobe Teilchen des Füllmaterials verhindert wird, vor ihrer Erhärtung alle die feinen Vertiefunhen der Form ganz auszufüllen und weil sich bei der Erhärtung leicht zwei Schichten bilden. Für gepreßte Gegenstände kann man wohl Füllmaterial einführen, aber die Masse wird dadurch leicht ungleichmäßig im Gefüge, und ,las Füllmaterial bleibt meistens sichtbar.To introduce paper, wood pulp or cellulose into the condensation products, is quite difficult, but hot-pressed liquid products can be used when using special equipment; for cast products, on the other hand, this is the case not possible because the liquid mass is made up of more or less coarse particles of the Filler material is prevented from hardening all the fine indentations to fill the mold completely and because two layers can easily be formed when it hardens form. Filling material can be introduced for pressed objects, but the As a result, the mass becomes slightly uneven in the structure, and the filler material remains mostly visible.

Es wurde nun gefunden, daß gemahlene Hydrozellulose und Oxyzellulose, hergestellt in bekannter Weise, durch Behandlung von Baumwolle, Papier oder Zellstoff mit Säuren oder s-)nstigen Oxydationsmitteln das beste Füllmaterial sowohl für gegossene als auch für gepreßte Produkte ergibt. Beispiel i. ioo Teile Phenol, i2o Teile 4oprozentiges Formalin, i Teil Ätzkali, 3o Teile Oxy zellulose, gewonnen durch Behandlung von Papier mit Salpetersäure, spei. Gew. 1,4. Das Gemisch wird im Gefäß mit Kühlapparat unter ständiger Mischung erhitzt, bis sich eine lackartige Masse bildet, und dann eingedampft, um das Wasser zu entfernen; nachdem die Masse abgekühlt ist, wird sie in Formen gegossen, «o sie unter Erwärmung hart wird. Beispiel 2. ioo Teile Lack aus ioo Teilen Kresol. ioo Teile 4oprozentiges Formalin und i Prozent Ätznatron, i5o Teile Hydrozellulose. Alles sorgfältig vermischt und eingekocht bis zur Bildung einer elastischen unschmelzbaren Masse, die gepreßt wird. Beispiel 3. iöo Teile Phenol, 3o Teile Hydrozellulose, 5 Teile Salzsäure 37prozentig, io Teile Erdölsulfosäuren 5oprozentig, So Teile Formalin 4oprozentig. Alles wird zum Sieden gebracht, das Wasser vom Harz abgeschieden, dann die Masse zwecks Entfernung von Wasserspuren eingekocht; dann werden bei q.0° C 5o Teile Formalin von 40 Prozent in das Vakuum eingebracht, alles vermischt und in Formen gegossen, wo die Masse unter Erhitzung erhärtet.It has now been found that ground hydrocellulose and oxycellulose, produced in a known manner, by treating cotton, paper or cellulose with acids or other oxidizing agents the best filler material for both cast as well as for pressed products. Example i. 100 parts phenol, 12o parts 4 percent Formalin, 1 part of caustic potash, 3o parts of oxy cellulose, obtained by treating Paper with nitric acid, spei. Weight 1.4. The mixture is placed in a vessel with a refrigerator heated with constant mixing until a varnish-like mass forms, and then evaporated to remove the water; after the mass has cooled, it becomes poured into molds, "o it hardens when heated. Example 2. 100 parts of paint from 100 parts of cresol. 100 parts 4 percent formalin and 1 percent caustic soda, i5o parts hydrocellulose. Everything carefully mixed and boiled down until formed an elastic infusible mass which is pressed. Example 3. iöo parts Phenol, 3o parts hydrocellulose, 5 parts 37 percent hydrochloric acid, 10 parts petroleum sulfonic acids 5 percent, so parts formalin 4 percent. Everything is boiling brought, the water separated from the resin, then the mass for the purpose of removing Traces of water boiled down; then at 0 ° C 50 parts formalin of 40 percent placed in the vacuum, mixed everything and poured into molds where the mass hardened under heating.
