Description

Die Erfindung betrifft ein Mittel gemäss dem Oberbegriff des Patentanspruchs 1.
Ein solches Mittel ist bereits aus der DE-PS 30 48 022 der An­ melderin bekannt geworden. Dieses Mittel besteht aus ca. 3% Rostschutzadditiv, ca. 5% Propylenglykol und (Rest) Isopropa­ nol; es besteht also hauptsächlich aus Isopropanol (ca. 92%) sowie Zusätzen von Propylenglykol und Rostschutzadditiv.
Dieses bekannte Mittel erfüllt schon weitgehend die an es ge­ stellte Aufgabe, die Bildung von Eis bzw. Vereisungen im Inneren des Bremssystems auch bei tiefen Aussentemperaturen zu verhin­ dern, und zwar ohne schädliche Nebenwirkungen, insbesondere ohne die Entfettung oder Rostbildung im Innern der Bremsanlagen. Es hat sich aber leider gezeigt, dass dieses Mittel noch nicht vollständig befriedigt, also noch verbesserungsbedürftig ist. Insbesondere ist in einigen Anwendungsfällen doch Entfettung im Innern der Bremsanlagen aufgetreten, wodurch die Geschmei­ digkeit und Gleitfähigkeit der Manschetten litten. In anderen Fällen kam es vor, dass Tropf-Dochte, aus denen das Mittel in die Bremsanlage eingegeben wird, verklebten, so dass der Nach­ schub des Mittels beeinträchtigt wurde. In anderen Fällen kamen Korrosionen an Metallteilen vor, die mit der Entfettung und Wasserbildung zusammenhängen dürften. Auch wurden Volumenver­ grösserungen an Dichtungen aus Gummi oder Kunststoff festge­ stellt.
Die vereinzelt aufgetretenen Mängel sind dabei unterschiedlich, je nach der Bauart der Bremsanlage und der Art ihres Betriebes.
Mit vorliegender Erfindung wird daher eine weitere Verbesserung erstrebt. Der Erfindung liegt die Aufgabe zugrunde, ein Frost­ schutz- und Pflegemittel der eingangs genannten Art anzugeben, welches Vereisungen ohne Nebenwirkungen zuverlässig verhindert (insoweit die gleiche Aufgabe wie bei dem bekannten Mittel), und welches darüber hinaus bei allen in Betrieb befindlichen Druck­ luftbremsanlagen Nebenwirkungen wie Entfettung und Korrosion verhindert. Dabei soll dieses Mittel auch zur Pflege, insbe­ sondere Schmierung, im Sommer eingesetzt werden können, also nicht nur als Frostschutzmittel.
Nach umfangreichen Versuchen ist als Lösung dieser Aufgabe die im Patentanspruch 1 angegebene Rezeptur gefunden worden.
Gegenüber dem vorbekannten Mittel wurde also der Anteil an Isopropanol herabgesetzt und durch Ethanol ersetzt. Statt bis­ her ca. 5% Propylenglykol werden nunmehr ca. 6,5% Etylen­ glykol eingesetzt.
Ferner wird gemäss der Erfindung der Anteil an Rostschutzadditiven von ca. 3% auf (nur) 0,1% herabgesetzt. Die Rostschutzadditive stellen schwerlösliche Substanzen dar, diese wurden also weit­ gehend herabgesetzt.
Vorzugsweise wird als Rostschutzadditiv Natriumbenzoat einge­ setzt.
