Definitions

  • the present invention relates to cleaning agents for removing heavy contaminants from outdoor vehicle surfaces containing amine oxides and polypeptides.
  • Aircraft Exterior Cleaners are not only for cleaning dirty aircraft, but are also essential for the economical operation of aircraft. Airplane aluminum surfaces are permanently contaminated with aviation gasoline, carbon fumes and lubricants during flight operations. Due to the dirt, the surface roughness increases, so that the necessary for the buoyancy air flow is slightly turbulent. As a result, more driving force and thus more fuel is needed to keep the aircraft at the desired cruising speed. Impurities can also cause corrosion of the aluminum components, which can lead to a significant impairment of flight safety.
  • Aircraft exterior cleaners must meet a large number of requirements. According to the SAE Specification AMS (Aerospace Material Standards) 1526 (Cleaner for aircraft exterior surfaces, water-miscible, pressure-spraying type) corrosion effect, hydrogen embrittlement, material compatibility and the stability of the cleaning agent are examined.
  • SAE Specification AMS Alospace Material Standards 1526 (Cleaner for aircraft exterior surfaces, water-miscible, pressure-spraying type) corrosion effect, hydrogen embrittlement, material compatibility and the stability of the cleaning agent are examined.
  • US 3,458,300 discloses a cleaner containing alumina particles intended to abrade soil from aircraft surfaces. Antistatic surfactants prevent the redeposition of dirt particles on the outer skin.
  • US 3 491 027 discloses a cleaning solution used on aircraft operating predominantly near the sea.
  • the agent is suitable for removing salt deposits from aircraft surfaces.
  • U.S. 3,948,819 discloses the synergistic effect obtained by the choice of two nonionic surfactants as soil release agents. A method for evaluating the cleaning effect is described.
  • US-5 496 413 discloses the combination of cleansing and growing components in a single cleaner.
  • US 5,516,459 discloses the use of alkylamine oxides in thickened aircraft exterior cleaners, however, the pH of the cleaners is well within the alkaline range and requires environmentally harmful alkali metal nitrites for corrosion inhibition.
  • U.S. 5,992,669 discloses a hard surface cleaner comprising an aqueous solution comprising 40 to 50% of a nonionic surfactant mixture of an alcohol ethoxylate and a C 8 to C 15 alkyldimethylamine oxide in a weight ratio of (5 to 15): 1 and 50 to Contains 60% of a nitrogen-containing builder.
  • U.S. 5,443,651 discloses a ferrous metal surface cleaner containing amino acids such as polyaspartic acid or aspartic acid / glutamic acid copolymers at most pH 7.
  • JP-57-128 797 discloses a vehicle cleaner containing a C 8 to C 22 amine oxide, a fatty alcohol alkoxylate, an alkaline builder and water.
  • US 5,880,078 discloses that the desired soil release behavior can be achieved by a combination of ethoxylated fatty alcohols of different HLB values.
  • the object of the invention was therefore to develop an aircraft exterior cleaner, which not only effectively removes dirt but additionally contains environmentally friendly corrosion inhibitors.
  • the cleaner should be free from solvents and other substances that can cause unpleasant odors due to their low vapor pressure, are easily flammable and beyond health can be.
  • the cleaner should be suitable for other means of transport except for aircraft.
  • Weight percentages are hereinafter based on the weight of the composition.
  • the composition contains 10 to 30 wt .-% of component a), 0.01 to 1 wt .-% of component b) and water ad 100 wt .-%.
  • the preferred weight ratio between components a) and b) is between 15: 1 and 2500: 1.
  • a preferred subject of the invention is the use of the composition according to the invention as exterior cleaner for aircraft.
  • Another object of the invention is a method for the exterior cleaning of means of transport, in particular of aircraft, by applying the composition of the invention to the outer skin of the means of transport to be cleaned.
  • the constituent a) of the composition according to the invention preferably accounts for 15 to 25 wt .-% of the total weight.
  • R 1 is preferably an alkyl, alkenyl, alkoxypropyl or alkenylamidoalkyl group having 10 to 16 carbon atoms.
  • R 2 and R 3 are preferably alkyl radicals having 1 to 6, in particular 1 to 4 C-atoms or may also mean hydroxyethyl or hydroxypropyl radicals.
  • Examples of constituent a) are: cocoalkyldimethylamine oxide, stearyldimethylamine oxide, lauryldimethylamine oxide and C 14 -alkyldimethylamine oxide.
  • Component a) may also be a mixture of the abovementioned amine oxides.
  • Component b) is an alkali metal salt of polyaspartic acid or polyglutamic acid having a molecular weight of preferably 7,000 g / mol to 20,000 g / mol, or a mixture of both substances.
  • These are readily degradable, non-toxic and water-soluble biopolymers, in particular polypeptides. So far, these compounds are mainly used as a dispersant in cooling water and for the removal of limescale. It has been shown that these substances are just as well suited as a corrosion inhibitor for use in aircraft exterior cleaners.
  • defoamers, dyes, complexing agents and antioxidants may be included in the cleaners.
  • the pH of aircraft exterior cleaners should generally be 6.5 to 11, preferably 9 to 10. If the composition according to the invention does not have such a pH, it can be adjusted by means of suitable pH regulators.
  • suitable basic compounds are those from the group of alkali metal hydroxides, such as NaOH and KOH.
  • composition of the invention is carried out by mixing the individual components in any order, which can be carried out for example in a container equipped with a stirrer.
  • the resulting formulations show excellent soil release power. Practical tests on motor vehicles have shown that even stubborn insect contamination on windscreens can be easily removed. The product leaves no streaks, contains no organic solvents and contains only environmentally friendly and easily degradable corrosion inhibitors.
  • 100 g of this artificial aircraft dirt consist of 1 g of lanolin, 20 g of activated carbon, 10 g of talc, 15 g of lubricating oil and 54 g of kerosene.
  • the components are intimately mixed and applied to the aluminum sheet in a thin film.
  • the dirt is then baked for 12 hours at 100 ° C in a drying oven in the aluminum sheet.
  • the aluminum sheet provided with plain bearing grease, vaseline or artificial aircraft soil is immersed in a solution of 100 ml of detergent.
  • the solution is in a beaker in which a magnetic stirrer rotates at 500 revolutions per minute. After regular intervals, an assessment of the detached dirt components is carried out.
  • An aircraft cleaning agent according to the invention is prepared by mixing the following components (concentrate): 15.00% by weight C 12 / C 14 alkyldimethylamine oxide 0.20% by weight Alkali metal polyaspartate at 15,000 g / mol 0.45% by weight caustic soda 84.35% by weight Water.
  • Example 1 Further investigations of the aircraft cleaning agent described in Example 1 show that all further requirements of the SAE specification AMS 1526 are met.
  • the product does not cause corrosion on aluminum, magnesium and steel alloys and does not affect acrylic glass, painted or unpainted aircraft surfaces.
  • An aircraft cleaning agent according to the invention is prepared by mixing the following components (concentrate): 25.00% by weight lauryl dimethyl 0.20% by weight Alkali metal polyglutamate at 35,000 g / mol 0.40% by weight potassium hydroxide 74.4% by weight Water.
