Definitions

  • the present invention relates to the use of a combination of nonionic surfactants - optionally with conventional additives - for cleaning hard surfaces in the spraying process. So-called “industrial cleaners” are usually used for such tasks.
  • Industrial cleaners of this type are mainly used in the automotive industry and their supplier industries for cleaning and passivation, primarily in spray cleaning systems. They are suitable for intermediate and final cleaning without cutting as well as machined parts in unit and assembly plants. Practically all relevant materials, such as iron and steel, aluminum, silumen, copper, brass, zinc and plastics, can be treated and the majority of all contaminations on an organic or inorganic basis, such as cooling lubricants, rust protection oils, processing oils, drawing aids, pigments and light metal abrasion, can be removed. Such cleaning agents can also be used in customary immersion processes, but their use in the spraying process is usually preferred.
  • cleaning agents of this type generally contain substances which are capable of an undesirable one Counteract foam development.
  • foam-inhibiting additives is in most cases due to the fact that the contaminants detached from the substrates and accumulating in the cleaning baths act as foaming agents.
  • anti-foaming agents may also be necessary due to the fact that the cleaning agents themselves contain constituents which give rise to undesirable foaming under the given working conditions - ie in particular in the case of spraying processes, for example anionic surfactants or nonionic surfactants foaming at the respective working temperature.
  • Such formulations can be used both for cleaning hard surfaces and for washing textiles.
  • Such surfactant mixtures are used in aqueous cleaning agents for cleaning hard surfaces, in particular also for spray cleaning at temperatures below 50 ° C.
  • the object of the present invention was to provide surfactant combinations for cleaning hard surfaces which have low-foaming properties in the entire temperature range relevant to the application, namely in the range from 15 to 80 ° C., and are therefore suitable for use in the spraying process.
  • these surfactant combinations should have a high cleaning ability and excellent wetting properties compared to the substrates treated with them; further should these surfactant combinations can be easily assembled with additives common in industrial cleaners, allow the cleaning agent solutions to run off the treated substrate surfaces without stains and have demulsifying properties with regard to non-self-emulsifying oils and fats.
  • R 1 represents a linear or branched alkyl radical or alkenyl radical having 6 to 18 carbon atoms.
  • the following radicals are therefore suitable as substituent R 1: n-hexyl, n-heptyl, n-octyl, n-nonyl, n-decyl, n-undecyl, n-dodecyl, n-tridecyl, n-tetradecyl, n-pentadecyl , n-hexadecyl, n-heptadecyl and n-octadecyl and the branched chain isomers of the alkyl radicals mentioned.
  • R 1 can also mean the unsaturated alkyl radicals (alkenyl radicals) with a number of carbon atoms in the above range, which can likewise be linear or branched.
  • component a those compounds of the general formula (I) in which R 1 is a linear alkyl radical or alkenyl radical having 6 to 18 carbon atoms.
  • R 1 is a linear alkyl radical or alkenyl radical having 6 to 18 carbon atoms.
  • R 2 represents a linear or branched alkyl radical or alkenyl radical with 6 to 18 carbon atoms or a cyclic alkyl radical with 5 to 6 carbon atoms. Suitable substituents R 2 are therefore all those radicals which have already been explained above in connection with the substituent R 1 of the general formula (I).
  • the number of ethoxy radicals in the molecule - index p - is in the range from 2 to 10.
  • the substituent A in the general formula (II) stands for propoxy radicals, the number of propoxy radicals - index (q + r) - in the range from 2 to 8 lies.
  • components b of the general formula (II) are preferably used as component b in which R 2 is a linear alkyl radical having 8 to 18 carbon atoms, p is a number in the range from 2 to 5 and A is propoxy radicals, and the sum (q + r) is a number in the range 4 to 6.
  • the reaction product of technical lauryl alcohol - which has alkyl radicals with 12 to 18 carbon atoms (thereof about 80% with 12 to 14 carbon atoms) - with 2 to 4 is used as the surfactant component b Moles of ethylene oxide and 4 to 6 moles of propylene oxide or the reaction product of n-octanol with 2 to 6 moles of ethylene oxide and 2 to 5 moles of propylene oxide.
  • the surfactant combinations to be used according to the invention contain, as additional component c, at least one alk (en) yl ethoxylate mixed ether of the general formula (III) R3-O- (CH2CH2O) s -R4 (III) in which R3 is a linear or branched alkyl radical or alkenyl radical with 6 to 18 carbon atoms or a cyclic alkyl radical with 5 to 6 carbon atoms, s is a number in the range from 2 to 12 and R4 is a linear or branched alkyl radical with 1 to 8 carbon atoms -Atoms mean, the weight ratio of components (a + b): c being in the range from 1: (0.1 to 4).
  • R3 therefore stands for a linear or branched alkyl radical or alkenyl radical with 6 to 18 carbon atoms or a cyclic alkyl radical with 5 to 6 carbon atoms.
  • Suitable substituents R3 are therefore all those radicals which have already been explained above in connection with the substituent R1 of the general formula (I).
  • the number of ethoxy radicals in the molecule - index s - is here in the range from 2 to 12.
  • the substituent R4 in the general formula (III) stands for a linear or branched alkyl radical with 1 to 8 C atoms; thus for methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, n-heptyl, n-octyl and for the corresponding branched-chain isomers.
  • alk (en) yl ethoxylate mixed ethers which are also referred to as end group-capped fatty alcohol polyethylene glycol ethers are described in more detail in DE-A-33 15 951, 37 27 378 and 38 00 490.
  • the production of these nonionic surfactants is also disclosed in detail in these German published publications.
  • At least one alkyl ethoxylate mixed ether of the general formula (III) as additional component c of the surfactant combination, where R 3 is a linear alkyl radical having 8 to 10 carbon atoms, s is a number in the range from 3 to 5 and R4 represent an n-butyl radical.
  • Particularly preferred mixed alkyl ethoxylate ethers of the general formula (III) are addition products of 3.5 to 4.5 mol of ethylene oxide onto fatty alcohols having 8 to 10 carbon atoms and etherified with an n-butyl radical.
  • the surfactant combinations to be used according to the invention are further characterized by a certain weight ratio of components a: b, which is generally in the range from 10: 1 to 1:10. If only these two components are used in the manner according to the invention, the preferred weight ratio of components a: b is in the range from 2: 1 to 1: 2. However, if the surfactant combination to be used according to the invention contains the additional component c, the weight ratio is of components (a + b): c in the range from 1: 0.1 to 1: 4, preferably in the range from 1: 0.1 to 1: 1.5.
  • the surfactant combinations to be used according to the invention are notable for high cleaning power at temperatures in the range from 15 to 80 ° C. They are in the temperature range mentioned can also be used without any problems in the spraying process since they do not cause any undesirable foam development. Further advantages are: very good wetting properties, very good demulsifying properties with regard to non-self-emulsifying oils and fats as well as easy assembly with additives commonly used in industrial cleaners.
  • additives which are preferably used in addition to the surfactant combinations to be used according to the invention are: builder substances and / or complexing agents, corrosion inhibitors and bases or acids.
  • stabilizers, solubilizers or antimicrobial agents can also be used as additives.

  • Straight-chain or branched aliphatic carboxylic acids or their salts are suitable as effective corrosion inhibitors.
  • alkanolamine salts of straight-chain or branched monocarboxylic acids with 8 to 11 carbon atoms are used as corrosion inhibitors.
  • the aqueous solutions of the surfactant combinations to be used according to the invention can be acidic or also alkaline; accordingly, they contain excess acid or bases, for example sodium hydroxide and / or potassium hydroxide.
