Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Reinigern aus Kunststoff-Schaumstoffen mit einem spez. Gewicht von o,o5 bis 0.2 g/cm3.The invention relates to a method for the production of cleaners made of plastic foams with a spec. Weight from 0.05 to 0.2 g / cm3.

Es ist bekannt, zum Reinigen von Händen oder Geräten das als Bimsstein bekannte Naturprodukt zu benutzen. Ferner ist es bekannt, das Naturprodukt mit der Handelsbezeichnung Luffa als Bade- oder @Iassageschwamm zu verwenden, wobei die starke frottierende Wirkung dieses Schwammes als sehr angenehm empfunden wird. Auch alkalisch reagierende, gegebenenfalls scheuernd wirkende Reinigungsmittel in Pulverform sind gebräuchlich. Die für Reinigungszwecke verwandten Gummischwämme zeichnen sich zwar durch sparsamen Seifenverbrauch aus, sind aber infolgeihrerweichen Struktur nicht für das Reinigen stark verschmutzter Hände oder Geräte geeignet. da sie keine scheuernde Wirkung haben.It is known to use the natural product known as pumice stone to clean hands or equipment. It is also known to use the natural product with the trade name Luffa as a bath or massage sponge, the strong otty effect of this sponge being felt to be very pleasant. Alkaline cleaning agents in powder form that may have an abrasive effect are also used. The rubber sponges used for cleaning purposes are characterized by their economical consumption of soap, but due to their soft structure they are not suitable for cleaning heavily soiled hands or devices. as they have no abrasive effect.

Ferner hat man schon vorgeschlagen, Reinigungskörper aus Kunststoff-Schaumstoffen unter Zusatz von Treibmitteln, Füllstoffen u. dgl. herzustellen, wobei als Kunststoffe härtbare Harze auf Phenol-oder Harnstoffbasis, Polystyrol sowie Vinylverbindungen vorgeschlagen wurden.Furthermore, it has already been proposed that cleaning bodies made of plastic foams with the addition of blowing agents, fillers and the like curable resins based on phenol or urea, polystyrene and vinyl compounds were proposed.

Gegenüber diesen bekannten Reinigern unterscheidet sich das erfindungsgemäße Verfahren dadurch, daß die Schaumstoffe aus kombinierten Polyurethanprodukten, gegebenenfalls unter Zugabe von Füllstoffen, Farbstoffen, Beschleunigern und Weichmachern, erzeugt werden. Hierbei führt die Verbindung von Polyestern mit Diisozyanaten zur Vernetzung und Auftreibung der Mischung, so daß ohne Zusatz von Treibmitteln und bei Raumtemperaturen ein Aufschäumen der Masse herbeigeführt werden kann. Bei den erfindungsgemäß zur Anwendung kommenden Kunststoff-Schaumstoffen kann ferner in vorteilhafter Weise durch Wahl geeigneter hart- oder weichmachender Polyester eine Warmplastizität bei 4o bis 5o° erreicht werden. Die Verarbeitung dieser Polyurethankombinationen erfolgt gemäß der Erfindung bei Temperaturen von 20 bis i5o° je nach Wahl der Rohstoffkomponenten, wodurch sämtliche Variationen von starrer bis elastischer und grobporiger bis feinporiger Struktur möglich sind und das spez. Gewicht dem Verwendungszweck des Endproduktes angepaßt werden kann. Die günstige Verarbeitungsmöglichkeit der Polyurethanprodukte erlaubt eine schnelle Fabrikation durch Gießen des schaumfähigen Ansatzes in Formen zu Blöcken oder Strängen nach einer vorangegangenen Vormischung mittels Rührwerken oder Schwingmischern in besonderen Mischgefäßen oder durch das bekannte Schwingmischen unmittelbar in der Form, wodurch,der Schäum- und Härteprozeß eingeleitet wird. Es kann aber auch die endgültige Form mit dem schaumfähigen Mischgut mittels einer Hochdruckpatrone beschickt werden, nachdem der sehr hohe Eigentrieb der Polyurethankombinationsmischungdurch eine vorangegangene Schwingmischung erzeugt wurde, so daß die bereits im Treibzustand befindliche :Mischung die Hauptform selbsttätig füllt und dort zur Aushärtung gelangt.Compared to these known cleaners, the one according to the invention differs Process in that the foams from combined polyurethane products, optionally with the addition of fillers, dyes, accelerators and plasticizers will. Here, the connection of polyesters with diisocyanates leads to crosslinking and expansion of the mixture so that without the addition of propellants and at room temperatures a foaming of the mass can be brought about. In the invention for Applied plastic foams can also be used in an advantageous manner through the choice of suitable hard- or plasticizing polyesters a warm plasticity 4o to 5o ° can be reached. The processing of these polyurethane combinations takes place according to the invention at temperatures from 20 to 150 ° depending on the choice of raw material components, whereby all variations from rigid to elastic and coarse to fine-pored Structure are possible and the spec. Weight of the intended use of the end product can be customized. The inexpensive processing option for polyurethane products allows quick fabrication by pouring the foamable approach into molds into blocks or strands after previous premixing using stirrers or vibratory mixers in special mixing vessels or by the well-known vibratory mixing directly in the form, whereby the foaming and hardening process is initiated. It but can also create the final shape with the foamable mix by means of a High-pressure cartridge are charged after the very high intrinsic drive of the polyurethane combination mixture a previous vibration mixture was generated, so that the already in the driving state located: mixture fills the main mold automatically and there is hardened.

In einer Weiterbildung des Erfindungsgedankens werden die Rohkomponenten getrennt in die Form verdüst, wodurch der Misch- Schäum- und Härteprozeßeingeleitet wird. Der allgemeine llärteprozeß kann durch Zuführung von äußerer Wärme oder durch Hochfrequenzbehandltnig wesentlich beschleunigt werden. -Nach Abschluß dieser Härtung ist nur mehr ein Abschleifen der beim Herstellungsverfahren entstandenen Hatit zwecks Freilegung des schaumigen Kernes erforderlich.In a further development of the inventive concept, the raw components sprayed separately into the mold, thereby initiating the mixing, foaming and hardening process will. The general hardening process can be carried out by supplying external heat or by High frequency treatment can be significantly accelerated. -After this hardening is complete is only a sanding down of the hatit created during the manufacturing process Exposure of the foamy core required.

In weiterer Ausgestaltung der Erfindung ist es zur Erhöhung der Rei.ni"#ungst\-irkung bei den Polyurethan-Schaumstoffen möglich, an sich bekannte alkalisch reagierende und scheuernd wirkende pulverförmige Reinigtinsinittel, gegebenenfalls ohne die üblichen erdigen' l)eimengungen, mit in die Polyurethankombination einzuarbeiten, die dann in der beschriebenen `'eise weiterverarbeitet werden kann.In a further embodiment of the invention, it is intended to increase the efficiency of the cleaning process possible in the case of polyurethane foams, known per se alkaline reacting and abrasive powder-form cleaning agents, optionally without the usual earthy ingredients to be incorporated into the polyurethane combination, which can then be further processed in the described way.

In der Zeichnung ist ein Schaumstoffblock i dargestellt, der durch mechanische \achhearbeitung in kleinere Formstücke 2 aufgeteilt ist sowie ein in Formen unmittelbar erzeugtes Formstück 3, bei dem durch Abschleifen die für den vorgesehenen Verwendungszweck ungeeignete Haut entfernt ist, so daß der Kern 4 frei liegt.In the drawing, a foam block i is shown, which is through mechanical \ achharbeitung is divided into smaller fittings 2 and an in Shapes directly produced molding 3, in which by grinding the for the Intended use unsuitable skin is removed, so that the core 4 is free lies.
