Abstract
Description
Die Erfindung betrifft eine Schreibflüssigkeit für Kugelschreiber aus einer Farbpaste.The invention relates to a writing fluid for Ballpoint pen made of a color paste.
Von modernen Schreibflüssigkeiten für Kugelschreiber, sogenannten Kugelschreibertinten, wird eine Fülle von Eigenschaften erwartet, die durch Auswahl geeigneter Komponenten positiv beeinflußt werden kann.Of modern writing fluids for ballpoint pens, so-called ballpoint pen inks, is an abundance of Properties expected by choosing suitable ones Components can be influenced positively.
Die Einstellung der Farbpaste auf eine Kugelschreiberspitze oder umgekehrt ist dabei von großer Bedeutung. Es ist vor allem wünschenswert, daß die Pastenabgabe während der ganzen Lebensdauer einer Kugelschreibermine gleich bleibt. Dies wird in der Regel durch den Einsatz einer teuren Edelstahlspitze mit einer Wolfram-Karbid-Kugel erreicht. Bei einfacheren Minensystemen wird dagegen in der Regel als Spitzenteil eine Buntmetallegierung in Kombination mit einer Edelstahl- oder Wolfram-Karbid-Kugel verwendet. Durch die erhöhte Verschleißanfälligkeit dieser Konfigurationen sinkt oder steigt der Pastenverbrauch. Bei einer reduzier teren Pastenabgabe wirkt die Schrift blaß, steigt die Pastenabgabe an, wird die Schreiblänge der Mine kürzer. In letzterem Fall kann es ferner beim Schreiben zu Klecksen und einem unsauberen Schriftbild kommen.Setting the color paste on a ballpoint pen tip or vice versa is of great importance. It is before it is all desirable that the paste delivery during the entire life of a ballpoint pen refill remains the same. This is usually done by using an expensive one Stainless steel tip reached with a tungsten carbide ball. With simpler mine systems, however, is usually used as Top part a non-ferrous metal alloy in combination with a stainless steel or tungsten carbide ball. By the increased susceptibility to wear of these configurations the paste consumption decreases or increases. With a reduced When the paste is dispensed, the writing looks pale, the increases Dispensing paste, the writing length of the lead becomes shorter. In the latter case, it can also be too blotchy when writing and come up with a dirty typeface.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schreibflüssigkeit der o.g. Art zu entwickeln, bei der eine preisgünstigere Kugel eingesetzt werden kann, ohne daß es zu einer erhöhten Verschleißanfälligkeit kommt.The present invention has for its object a Writing fluid of the above Kind of developing one cheaper ball can be used without it leads to increased susceptibility to wear.
Zur Lösung dieser Aufgabe führt, daß der Farbpaste ein Gleitmittel zugesetzt ist.The solution to this problem is that the color paste Lubricant is added.
Dieses Gleitmittel hat die Wirkung, daß die Reibung beim Austritt der Farbpaste aus der Spitze vorbei an der Kugel vermindert wird. Hierdurch wird die Verschleißanfälligkeit der Kugel wesentlich herabgesetzt.This lubricant has the effect that the friction when Color paste emerges from the tip past the ball is reduced. This makes it susceptible to wear the ball significantly reduced.
Als Gleitmittel kommt bevorzugt ein Polytetrafluoräthylen in Betracht. In einem bevorzugten Ausführungsbeispiel werden der Farbpaste mikronisierte Teflonpigmente zugesetzt, welche die Gleiteigenschaften der Kugel äußerst vorteilhaft beeinflussen. Die Teilchengröße der Teflonpigmente liegt bevorzugt bei unter 25 µm. Die Menge der zugesetzten Teflonpigmente soll 20 Volumenprozent der Farbpaste nicht übersteigen. In der Regel dürfte die Menge bei bis zu 5% liegen.A polytetrafluoroethylene is preferably used as the lubricant into consideration. In a preferred embodiment become the color paste micronized Teflon pigments added, which extremely the sliding properties of the ball influence advantageous. The particle size of the Teflon pigments are preferably less than 25 µm. The amount of the added Teflon pigments is said to be 20 percent by volume Do not exceed color paste. As a rule, the amount should are up to 5%.
Je nach Anforderungen der DIN-Norm weisen die einzelnen bevorzugten Schreibflüssigkeiten eine unterschiedliche Viskosität und Zusammensetzung auf. Die oben erwähnten Gleitmittelzusätze können all diesen Zusammensetzungen zugefügt werden.Depending on the requirements of the DIN standard, the individual preferred writing fluids a different Viscosity and composition. The above mentioned Lubricant additives can be used in all of these compositions be added.
