Description

Verfahren zur Herstellung von Puppen und Puppenteilen als Hohlkörper durch Aufblähen von Hartkautschukmischungen Die Erfindung bezieht sich auf die Herstellung von Puppen und Puppenteilen als Hartkautschukhohlkörper durch Aufblähen von Hartkautschukmasse mit Hilfe von chemischen Treibstoffen beim Vulkanisationsvorgang.Process for the production of dolls and doll parts as hollow bodies by expanding hard rubber mixtures. The invention relates to manufacture of dolls and doll parts as hard rubber hollow bodies by inflating hard rubber mass with the help of chemical fuels during the vulcanization process.

Die serienweise Herstellung derartiger Puppen bereitet erhebliche Schwierigkeiten. Die Ursache liegt darin, daß der Hartkautschuk schon während des zum Aufblähen und Verformen nötigen Heizers zu vulkanisieren beginnt und dann nicht mehr zuverlässig in alle Formteile einfließen kann.The series production of such dolls prepares considerable Trouble. The reason is that the hard rubber already during the the heater necessary for inflating and deforming begins to vulcanize and then does not can flow more reliably into all molded parts.

Zur Herstellung von Weichkautschukhohlkörpern, insbesondere Kautschukbällen, hat man die Verwendung von Ammoniak in fester Tablettenform in Vorschlag gebracht. Diese Tabletten hat man mit einem Beschl°unigerzusatz versehen und die Kautschukmischung ohne Beschleuniger hergestellt. In der Praxis haben sich derartige Treibtabletten bisher nicht bewährt.For the production of soft rubber hollow bodies, especially rubber balls, the use of ammonia in solid tablet form has been proposed. These tablets have been provided with an accelerator additive and the rubber mixture produced without accelerator. In practice, such driving tablets have proven themselves not yet proven.

Es wurde nun gefunden, daß es gelingt, ein. zuverlässiges Einfließen der Hartkautschukinischung in die Formen zu ,erreichen, wenn an Stelle der bisher verwendeten meist trokkenen Treibmittel wäßrige Treibmittel in Form von angepaßt konzentrierten, mehr als i 2 %igen Ammoniaklösungen benutzt werden-Diese Lösungen treiben schon bei niedrigeren Temperaturen sehr stark und wirken etwas verzögernd auf die Vulkanisation. in einer bisher nicht sicher erklärbaren Weise. Die Form wird schnell, gut und rein ausgefüllt und vulkanisiert danach schnell aus. Dabei wirkt die Ammioniaklösung im Beginn, wie dargestellt, verzögernd und danach, soweit erkennbar, stark beschleunigend auf die Vulkanisation der Mischung.It has now been found that one succeeds. reliable flow the hard rubber compound in the molds to achieve, if in place of the previously mostly used dry propellants aqueous propellants in the form of adapted concentrated ammonia solutions with more than 2% strength are used - these solutions drift very strongly even at lower temperatures and have a somewhat retarding effect on vulcanization. in a way that has not yet been explained with certainty. Form is filled in quickly, well and cleanly, and then quickly vulcanizes out. Included The ammionia solution has a retarding effect at the beginning, as shown, and then so far recognizable, strongly accelerating the vulcanization of the mixture.

Wichtig ist es, daß die Ammoniaklösungen möglichst mehr als 12 Teile Ammoniak in ioo Teilen der verwendeten Flüssigkeiten enthalten. Besonders gute Ergebnisse werden mit einer 25- bis 3oo%igen Lösung erzielt.It is important that the ammonia solutions contain more than 12 parts if possible Ammonia is contained in 100 parts of the liquids used. Particularly good results are achieved with a 25 to 3oo% solution.

Als Ammoniaklösungen können wäßrige, alkoholische o. dgl. Lösungen benutzt werden. Beispiel Bei Verwendung einer Hartkautschukmischung, bestehend aus 7,0o kg Rohkautschuk, 3,oo kg Hartkautschukstaub, 2,5o kg Schwefel, i, 5 o kg Zinkweiß, i, 5 o kg Kalk, o, i o kg Stearinsäure, 3,oo kg Kieselkreide, i, i 2 kg Kaolin oder Schwerspat nebst einem geeigneten Vulkanisati@onsbeschleuniger und einer 25o/oigen Amm@oniaklösung, fließen beim Aufheizen der mit den Massen beschickten Formen die Massen leicht in die Formen ein. Die Vulkanisation erfolgt bei Anwen- dung eines Druckes von 3i/, bis q.1/2 Atm. während der Dauer von etwa 6o Minuten. Aqueous, alcoholic or the like solutions can be used as ammonia solutions. Example When using a hard rubber mixture consisting of 7.0 kg of raw rubber, 3.0 kg of hard rubber dust, 2.5 kg of sulfur, 1.5 kg of zinc white, 1.5 kg of lime, 0.1 kg of stearic acid, 3.0 kg Silica chalk, 1, 2 kg of kaolin or barite together with a suitable vulcanization accelerator and a 25% ammonia solution, the masses easily flow into the molds when the molds loaded with the masses are heated. The vulcanization takes place when the Creation of a pressure of 3 1/2 to 1 1/2 atm. for a period of about 60 minutes.
