Description

Als Gegenstand der Erfindung ist das Kühlmittel, das zur Kühlung verschiedener Typen der mit Wasserkühler ausgerüsteten Motoren, be­ sonders aber der Automotoren, verwendet wird. Es kann auch die An­ wendung als hydraulische Flüssigkeit sowie der Wärmeträger in den Systemen der Fernheizung finden.The subject of the invention is the coolant used for cooling different types of engines equipped with water coolers, be especially the car engines. It can also be the An application as a hydraulic fluid as well as the heat transfer medium in the Find district heating systems.

Aus der polnischen Patentanmeldung P-2 50 721 ist das Kühlmittel, das aus 57-60 Gew.-% des Diglykols, 38-42 Gew.-% des Hartwassers mit einer Zugabe von 0,03-0,4 Gew.-% der Komplexonen sowie aus 0,0005 bis 0,001 Gew.-% des Farbstoffes, 1,1-2,3 Gew.-% der Korro­ sionsinhibitoren und aus 0,48-0,56 Gew.-% des Puffermittels, das gleichzeitig die Rolle des zusätzlichen Korrosionsinhibitors erfüllt, be­ steht.From the Polish patent application P-2 50 721 the coolant is the from 57-60% by weight of the diglycol, 38-42% by weight of the hard water with an addition of 0.03-0.4 wt .-% of the complexones and from 0.0005 to 0.001% by weight of the dye, 1.1-2.3% by weight of the corro sionsinhibitoren and from 0.48-0.56 wt .-% of the buffering agent, the at the same time fulfills the role of the additional corrosion inhibitor, be stands.

Diese Flüssigkeit erfüllt im Bereich der Alkalireserve die Anforderun­ gen des polnischen Standards und des Fiat-Standards. Beide Standarde sehen für die frische Kühlflüssigkeit eine Alkalireserve nicht niedriger als 8 ml HCL 0,1 N/20 ml vor. Man hat jedoch festgestellt, daß die Al­ kalireserve während der längeren Betriebszeit der Flüssigkeit einer nicht großen, jedoch einige Prozente betragende Erniedrigung unterliegt.This liquid meets the requirements in the area of the alkali reserve against the Polish and Fiat standards. Both standards do not see an alkali reserve lower for the fresh coolant as 8 ml HCL 0.1 N / 20 ml. However, it has been found that the Al Kalireserve during the longer operating time of the liquid not subject to major humiliation, but a few percent.

Als Ziel der Erfindung ist die Erhöhung des Wertes der Flüssigkeits­ alkalireserve zu einem Wert, der zusätzliche Anforderungen des ameri­ kanischen Standards, d. h. 10 ml HCL 0,1 N/20 ml erfüllen und gleich­ zeitig die Stabilität der Flüssigkeit erhöhen wird.The aim of the invention is to increase the value of the liquid alkali reserve at a value that meets the additional requirements of the ameri Canadian standards, d. H. Fill 10 ml HCL 0.1 N / 20 ml and the same will increase the stability of the liquid at an early stage.

Die Lösung der Erfindung liegt in der Zusammensetzung der über das Teil des Diglykols liegenden Flüssigkeit durch 10-20 Gew.-% der Polyole, die die Hydroxylgruppe in der Lage 1,2 besitzt. Es erfolgt Entstehung in der Flüssigkeitszusammensetzung der Komplexe mit einem sauren Charakter, dank der das ganze System einen niedrigeren pH- Wert als die Zusammensetzung ohne Polyole mit den Gruppen OH erhält. Gleichzeitig erfordert diese Zusammensetzung diese Menge den pH-Wert erniedrigerenden Substanzen, was zur Erhöhung der Alkalireserve der gesamten Flüssigkeit führt.The solution of the invention lies in the composition of the above Part of the diglycol is 10-20% by weight of the liquid Polyols that have the hydroxyl group capable of 1,2. It takes place  Formation in the liquid composition of the complexes with a acidic character, thanks to which the whole system has a lower pH Value obtained as the composition without polyols with the groups OH. At the same time, this composition requires this amount of pH degrading substances, which increase the alkali reserve of all liquid leads.

Das Kühlmittel nach der Erfindung enthält 57-60 Gew.-% der Mischung von Glykol und Polyolen mit den Gruppen OH in der Lage 1,2 - vorteil­ haft eine Mischung des Äthylenglykols im Verhältnis 5 : 1 bis 2 : 1, 38-42 Gew.-% des Hartwassers mit der Zugabe von 0,03 bis 0,45 Gew.-% des Dinatriumversanians, 1,02-2 Gew.-% des Boraxes, 0,03- 0,1 Gew.-% des Dextrins und 0,0005-0,001 Gew.-% des Fluoresenzins sowie die Mischung von 2-Mercaptobenzothiazol in einer Menge von 0,0005-0,15 Gew.-% mit 0,05 bis 0,15 Gew.-% das Triäthanolamin und das Puffermittel - vorteilhaft Phosphorsäure in einer Menge, die den pH-Wert in den Grenzen von 7,5-8,5 garantiert, besteht.The coolant according to the invention contains 57-60 wt .-% of the mixture of glycol and polyols with the OH groups in the 1,2 position - advantageously a mixture of ethylene glycol in a ratio of 5: 1 to 2: 1, 38-42 wt % of the hard water with the addition of 0.03 to 0.45% by weight of the disodium versanian, 1.02-2% by weight of the borax, 0.03-0.1% by weight of the dextrin and 0 .0005-0.001 wt .-% of the fluorescent and the mixture of 2-mercaptobenzothiazole in an amount of 0.0005-0.15 wt .-% with 0.05 to 0.15 wt .-% the triethanolamine and the buffering agent - advantageous phosphoric acid in an amount that guarantees the pH in the range of 7.5-8.5.

Auf diese Weise modifizierte Zusammensetzung der Kühlflüssigkeit sichert ihr eine stabile Alkalireserve mit einem Wert von über 10 ml HCL 0,1 N/20 ml, was zusätzlich die Bedingungen des amerikanischen Standards erfüllt und eine Verlängerung der Betriebszeit der Flüssigkeit sowie die Erreichung des Mehrsaisoncharakters erlaubt. Das in der Flüssig­ keit enthaltene Hartwasser erleichtert das Betreiben der Flüssigkeit.In this way, the modified composition of the cooling liquid ensures a stable alkali reserve with a value of more than 10 ml HCL 0.1 N / 20 ml, which also fulfills the conditions of the American standard and allows the operating time of the liquid to be extended and the multi-season character to be achieved. The hard water contained in the liquid facilitates the operation of the liquid.
