Definitions
- the present invention relates to a solvent-based cleaning liquid with reduced flammability for the maintenance, care, repair and assembly of vehicle parts and vehicles, in particular motor vehicle parts such as engines, brakes, etc.
- Solvent-based cleaning fluids are used to a large extent in motor vehicle workshops for cleaning motor vehicle parts, in particular engines and transmissions, the engine compartment and in particular the brakes, which are subject to heavy soiling due to brake pad wear.
- the cleaning liquids used for this are usually in aerosol spray cans and are sprayed onto the surfaces to be cleaned using a pressurized propellant.
- These conventional cleaning liquids generally contain low-boiling organic solvents which, after being sprayed onto the surface to be cleaned, dissolve the impurities and, with the entrainment of the contaminants, flow off and drip off the surface.
- cleaning work may be carried out with flammable liquids of class AI, but not with petrol, if they are carried out in a special, shielded room that meets the conditions for explosion-proof rooms, or in other rooms if they are absolutely necessary due to special circumstances .
- the entrepreneur must order the use of the cleaning agents in each individual case and take appropriate protective measures.

- the cleaning liquid according to the invention is present as an aerosol liquid in a spray can and contains 0.5 to 10% by weight, preferably 1 to 5% by weight, of at least one liquefied or compressed propellant gas for spraying the cleaning liquid out of the spray can.
- This propellant is a gas that is gaseous under normal conditions, but can be easily compressed or liquefied.
- the cleaning liquid of this embodiment of the invention preferably contains CO 2 , N 2 , SF ⁇ and / or a fluorocarbon propellant such as 1, 1, 1, 2-tetrafluoroethylene (HFA-134a) and / or 1, 1, 1 as the propellant gas , 2,3,3,3-heptafluoropropane (HFA-227).
- Carbon dioxide (CO 2 ) is preferably used as the propellant gas, which dissolves in the cleaning liquid according to the invention in a sufficient amount, for example in an amount of about 5% to 7%, and contributes to a further reduction in the risk of ignition.
- SF ⁇ sulfur hexafluoride
- the cleaning liquid contained as an aerosol liquid in a spray can 0.05 to 0.5% by weight of morpholine as a means of preventing corrosion of the metal spray can.
- a cleaning liquid according to the invention is prepared by mixing the following components:
- Bayer AG 2.0 wt .- ⁇ CO 2 0.5 wt .- *;
- a cleaning liquid according to the invention is prepared by mixing the following components:
- a cleaning liquid according to the invention is prepared by mixing the following components:
- Ethanol (96%) azeotropic mixture of 96% ethanol and 4% water
- a cleaning liquid according to the invention is prepared by mixing the following components:
- Isopropanol (87.4%) azeotropic mixture of 87.4% by weight isopropanol and 12.6% by weight water.
- Cleaning liquid in the form of an aerosol cleaning liquid in a spray can is provided.
- the aerosol cleaning liquid a mixture of 96.5% by weight of the cleaning liquid specified in Example 1 is used, 0.1% morpholine is added as an anti-corrosion agent, and the cleaning liquids are filled. liquid into a pressure spray can and fill it with 3.4% by weight of carbon dioxide.
- This aerosol cleaning liquid can easily be sprayed under the intrinsic pressure of the carbon dioxide propellant and enables a cleaning effect which corresponds to that of a conventional cleaning liquid based on petrol as a solvent and a propane / butane mixture as a propellant and shows a significantly lower level Flammability.
- Cleaning liquid in the form of an aerosol liquid in a spray can in the following composition:
- Isopropanol (87.4%) azeotropic mixture of 87.4% by weight of isopropanol and 12.6% by weight of water ** Gasoline with a boiling range from 60 0 C to 95 ° C

- Isopropanol, acetone, 3,5-dimethyl-1-hexin-3-ol and octamethylcyclotetrasiloxane are mixed, this mixture is introduced into a pressure spray can and filled with 4.0% by weight of carbon dioxide.
- a spray jet of the aerosol cleaning liquids to be examined is sprayed horizontally onto a hot surface at a distance of at least 60 cm.
- the aerosol can containing the cleaning liquid to be examined is clamped in a device with an electromechanical spray-copy actuation, in such a way that there is a horizontal connecting line to the hottest point of the hot surface located vertically in a housing in the form of a heating element.
- the heating element to be used is examined with regard to its temperature profile before starting the ignition tests.
- the heating element is heated up in a vertical position and the temperatures at the five measuring points are recorded in order to determine the hottest zone of the heating element, at which a single thermocouple for measuring the temperature is then arranged.
- the heating element with the attached thermocouple is inserted vertically into a sheet steel housing and attached to a tripod.
- the heating element is arranged in such a way that the measuring point of the thermocouple is in the center of the housing and the open side of the housing is aligned in a direct line to the aerosol can, with a horizontal distance between the spray head of the aerosol can and the hottest surface of the heating element of 60 cm results.
- the ignition tests are carried out in a draft-free location, the location being effectively ventilated before and after each ignition attempt in order to remove flammable gases and vapors as combustion products.
- the room temperature is 20 0 C ⁇ 2 ° C.
- the aerosol cans to be examined are heated prior to the experiment at 20 0 C ⁇ 1 ° C and the internal pressure is measured before the start of the ignition tests with the aid of a pressure gauge.
- the ignition experiments are carried out by varying the surface temperature of the heating element until the ignition of the spray jet and / or the aerosol / vapor cloud formed is visible as a result of ignition.
- a single spray process is triggered and registered, whether or not ignition occurs at the selected heating element temperature.
- the lowest possible surface temperature for inflammation is determined at four different spray times (0.5, 1, 0, 1, 5 and 2.0 s). A longer spraying time than 2 seconds is avoided due to the risk of an excessive amount of explosive mixtures being formed.
- a surface temperature of the heating element of 780 ° C. which is both above the ignition temperature of the comparison aerosol cleaning liquids and the aerosol cleaning liquids according to the invention, is used to check whether there is a (possibly only partial) There is a flashback in the direction of the spray head and whether the ignited residual amount of the aerosol cleaning liquid can continue to burn on the inside of the housing after the ignition.
- Composition A Commercial A II brake cleaner
- Composition B Comparative aerosol cleaning liquid
- Composition C Comparative aerosol cleaning liquid
- compositions B and C were prepared from the ingredients listed in the manner given in Example 6.
- the conventional aerosol cleaning liquid A has an ignition temperature of 660 0 C, while the aerosol according to the invention Example 6 ignites cleaning liquid according to only at a temperature> 780 ° C.
- the examination of the aerosol cleaning fluids according to the invention shows that, with the same cleaning effect, they have a significantly higher ignition temperature of 780 ° C. compared to 660 ° C. of the commercially available brake cleaning fluid A.
- the aerosol cleaning fluids according to the invention of Examples 6 and 7 have a significantly more favorable burning behavior, in that they ignite at the specified high ignition temperature of 780 ° C. but do not show any flashback and no further burning.
- the comparison aerosol cleaning liquids B and C result in a clear flashback and thus a potential high risk to the user of such cleaning liquids even if the cleaning liquid contains a considerable amount of isopropanol (comparison liquid C).
- the cleaning fluids according to the invention have a higher ignition temperature and have a significant improvement in safety in use, because at the stated very high ignition temperature - hardly any in normal application will occur - show no flashback and no further burning of the sprayed material.
