Abstract

Liq. slip grinding agent is composed of above 50% of a surfactant, water and 2-15% of a solubilising agent consisting of polyethylene glycol with an average mol. wt. of 200-400. A typical compsn. comprises 40% water, 55% surfactant mixt. and 5% polyethylene glycol. USE/ADVANTAGE - The slip grinding agents are used during slip grinding, esp. vibration slip grinding, to intensify the grinding action and/or to optimise the ground surface. Known slip grinding agents use low alcohols as solubilising agents for the surfactant, but these have the disadvantages of flammability, toxicity and of lowering the corrosion resistance of the material being ground. These disadvantages are now overcome by using a low polyethylene glycol as solubilising agent. (2pp Dwg.No.0/0)

Description

Beim Gleitschleifen, insbesondere Vibrationsgleitschlei­ fen, ist es bekannt, flüssige Gleitschleif-Behandlungs­ mittel zu verwenden, insbesondere zur Intensivierung des Schleifprozesses und/oder Optimierung der Werkstückober­ fläche. Solche Gleitschleif-Behandlungsmittel enthalten zur Erhöhung der Wirksamkeit Tenside. Um diese Tenside mischbar zu machen, enthalten die Gleitschleif-Behand­ lungsmittel gleichzeitig als Komponente einen niederen Alkohl, vorzugsweise Isopropanol. Dieser alkoholische Lösungsvermittler hat dann gleichzeitig die Funktion einer entfettenden Wirkung auf die Werkstückoberfläche. Eingesetzt werden diese Alkohole in Konzentrationen zwischen 2% und 15%.For vibratory grinding, especially vibratory vibratory grinding fen, it is known to be liquid tumble treatment to use medium, in particular to intensify the Grinding process and / or optimization of the workpiece top area. Such finishing grinding agents contain to increase the effectiveness of surfactants. To these surfactants The slide grinding treatments contain miscibility at the same time as a component Alcohol, preferably isopropanol. This alcoholic Solution broker then also has the function a degreasing effect on the workpiece surface. These alcohols are used in concentrations between 2% and 15%.

Nachteilig beim Einsatz dieser Alkohole sind der niedri­ ge Flammpunkt, den das Behandlungsmittel durch den Ein­ satz des Alkohols erhält und - wie gefunden wurde - die Verschlechterung der Korrosionsschutzwirkung des Produk­ tes. Der niedrige Flammpunkt bringt das Risiko der Ent­ zündbarkeit des Produktes. Damit sind zusätzliche Kompli­ kationen bzw. Vorsichtsmaßnahmen beim Transport, bei der Lagerung und beim Gerbrauch verbunden. Diese sind insbe­ sondere beim Gebrauch erheblich, weil sich gerade beim Vibrationsgleitschleifen bei möglichst großer Ausnutzung des Innenvolumens des Gleitschleifvibrators auch ange­ sichts der Vibrationsbewegungen und der bei solchen Vibratoren üblichen Werkstücktrennung nach Vollendung des Gleitschleifens kaum vermeiden läßt, daß kleine Mengen des Behandlungsmittels auch aus dem Vibrations­ gleitschleifbehälter gelangen, z. B. durch Spritzer.The disadvantage of using these alcohols is that they are low The flash point that the treatment agent receives from the receives alcohol and - as was found - the Deterioration of the anti-corrosion effect of the product tes. The low flash point brings the risk of Ent ignitability of the product. This is additional compli cations or precautionary measures during transport, when Storage and associated with use. These are esp especially with the use considerably, because the Vibration slide grinding with the greatest possible utilization the inner volume of the vibratory vibratory vibrator is also attached in terms of vibration movements and those Vibrators usual workpiece separation after completion of slide grinding can hardly be avoided that small Amounts of the treatment agent also from the vibration slide grinding container arrive, for. B. by splashes.

Aufgabe der Erfindung ist es, ein Gleitschleif-Behand­ lungsmittel anzugeben, welches die oben aufgeführten Nachteile vermeidet.The object of the invention is a surface finishing treatment to indicate which of the above Avoids disadvantages.

Gelöst ist dies durch die im Anspruch angegebene Erfin­ dung.This is solved by the inventor specified in the claim dung.

Zufolge dieses Vorschlages, in entsprechender Weise Polyethylenglycol als Lösungsvermittler zu verwenden, ergibt sich neben dem Effekt des wesentlich höheren Flamm­ punktes überraschenderweise die Eigenschaft eines optima­ len Korrosionsschutzes für das Werkstück, welcher Korro­ sionsschutz auch längerfristig erhaltbar ist. Außerdem ist das gesamte flüssige Gleitschleif-Behandlungsmittel weniger toxisch.As a result of this proposal, in a corresponding manner To use polyethylene glycol as a solubilizer, in addition to the effect of the much higher flame surprisingly, the property of an optima len corrosion protection for the workpiece, which Korro protection can also be obtained in the long term. Furthermore is the entire liquid surface finishing treatment less toxic.

Eine typische Zusammensetzung für ein entsprechend der Erfindung zusammengesetztes Gleitschleif-Behandlungsmit­ tel ist:A typical composition for one according to the Invention composite finishing treatment with tel is:

40% Wasser
55% Tensidgemisch
5% Polyethylenglycol.40% water
55% surfactant mixture
5% polyethylene glycol.

Zur kumulativen Erzielung der angegebenen Vorteile hat sich ein Polyethylenglycol des mittleren Molekulargewich­ tes zwischen 200 und 400 als optimal erwiesen.To achieve the stated advantages cumulatively a polyethylene glycol of average molecular weight tes between 200 and 400 proved to be optimal.

Die in der vorstehenden Beschreibung, der Zeichnung und den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung von Bedeutung sein. Alle offenbarten Merkmale sind erfindungswesentlich.The in the above description, the drawing and Features of the invention disclosed in the claims can both individually and in any combination for the realization of the invention may be of importance. All disclosed features are essential to the invention.
