Definitions

  • the invention relates to a demulsifying cleaning agent, which is particularly suitable for removal of oil and grease contamination.
  • the area of use of such demulsifying cleaning agents is in particular the area of vehicle washing systems, such as. Car washes or train cleaning systems are often provided High-pressure cleaning devices are used.
  • the cleaning agents used to date for cleaning painted and unpainted surfaces from vehicles, engines, floors, facades, airplanes, etc. remove the Oil and fat contaminations by emulsifying from the surface and transfer the oil and Fat components and the contaminant particles contained therein in the transport medium water.
  • FR-A 21 63 577 describes a large number of nonionic agents, some combined with anionic Surfactants known as detergent mixtures for use in car washes. However revealed this publication does not contain any demulsifying surfactant mixtures.
  • Another surfactant mixture for car washes is known from GB-A 2 134 132, which in addition to the surfactants contains a portion of an organic Contains solvent. However, these surfactant mixtures have no demulsifying effect.
  • EP-A 213 554 also discloses a demulsifying cleaning agent with a surface moisturizing effect known whose composition contains nonionic and anionic surfactants in particular suitable for the absorption of fats and oils and for the cleaning of vertical surfaces special formulation of the cleaning agent a so-called surface moisturizing effect is achieved.
  • This cleaning agent separates the oil and fat components of the after a certain period of time Contamination from the demulsifying effect, so that these parts from the dirty water phase have it separated.
  • the overall cleaning effect of these cleaning agents is unsatisfactory especially with regard to the removal of mineral soiling, e.g. Dust or pollen.
  • the object of the invention is to propose a demulsifying cleaning agent which is widely used Temperature range for both oil and grease as well as mineral contamination from those to be cleaned Satisfies objects in a satisfactory form and which in particular in the cleaning phase emulsified hydrocarbons of any kind immediately when the wastewater is at rest as a separate phase separates.
  • the cleaning agent of the present invention should also be particularly suitable for use in High-pressure cleaning devices and brush washers are suitable.
  • the separation effect in the wastewater should in particular also meet the new requirements for the sewage to be discharged into the public sewer network is sufficient, as is the case, for example, in Appendix 49 of the General framework administration regulation on minimum requirements for the discharge of waste water into Waters of December 19, 1989.
  • Detergents of this type are ideally suited to oil and greasy soiling in particular also contain mineral contaminants, such as dusts or pollen, in one wide temperature range of approx. 15 to 70 ° C. Those emulsified during the cleaning process Hydrocarbons, fats and oils of any kind are immediately removed from the wastewater at rest separated, and so completely that the separable demulsified wastewater meets the latest wastewater regulations completely corresponds.
  • the cleaning agents according to the invention achieve a very good cleaning effect with economical Use of detergent.
  • An important advantage of the cleaning agent according to the invention is that even the large temperature range of 15 to 70 ° C the demulsifying properties are not lost what is not guaranteed with conventional cleaning agents of this type.
  • 15 ° C is usually the Water temperature that the cold water from the public water supply has.
  • the temperature of 70 ° C is usually the impact of a hot water high pressure jet on a cleaning object not exceeded.
  • the cleaning agent according to the invention can be used universally for all possible types of dirt, in particular also for mixed soiling from oil and grease as well as mineral soiling, the demulsifying effect is not lost.
  • the key feature here is the mixing ratio of the nonionic surfactants, which is expressed in the HLB G value.
  • the ratio of anionic and nonionic surfactants is also critical, since one is not correct mixing can disturb the demulsifying effect.
  • the cleaning agents according to the invention can be either in solid form or in liquid form available.
  • the cleaning agent according to the invention can be used as a concentrate or as a preparation with water Means are formulated.
  • solubilizer in a quantity from 0.5 to 18% by weight added.
  • a particular advantage of the present detergent mixtures is that they are phosphate-free can be produced.
  • alkylbenzenesulfonates are preferred as the anionic surfactant are, so that preferred cleaning agents mainly contain those as anionic surfactants, the Weight ratio V between nonionic and anionic surfactants in this case is 3.5 to 12.5.
  • dialkyl sulfonate succinates have also proven useful as anionic surfactants, and in the case that these anionic surfactants are predominantly present in the cleaning agent becomes a weight ratio V selected from 2.9 to 11.
  • anionic surfactants are the alkylnaphthalenesulfonates, the then the weight ratio V is set to 3.5 to 12.
  • alkyl sulfonates Another group of substances with which very good cleaning effects are achieved are the alkyl sulfonates, and in this case the weight ratio V will preferably be 4 to 16.
  • alkylbenzenesulfonates the salts of sodium and ammonium and Triethanolamine preferred.
  • the nonionic surfactants are preferably selected from the group of C 13-15 oxo alcohols which, alone or in a mixture with C 9 to C 15 fatty alcohol compounds, can provide the total nonionic surfactant content.
  • nonionic surfactants in the cleaning agent according to the invention can be processed very well using cold and hot water high-pressure devices without the Operation of the device is impaired by noticeable incrustations in the temperature range above 60 ° C would.
  • This Complexing agents or also called builders are usually present in a proportion of 0.5 to 25% by weight Detergent included.
  • Corrosion inhibitors for Light and non-ferrous metals are added.
  • the weight fraction of these substances is often between 0.1 and 25% by weight of the detergent.
  • additives such as e.g. Complexing agents, corrosion inhibitors, color and fragrances for the cleaning agent according to the invention, its basic structure and Do not change the characteristic, but that only additional, already known side effects are used here will.
  • the complexing agents are usually selected from the group EDTA, NTA, phosphonic acids and their soluble salts selected.
  • the substances can be used individually or as a mixture become.
  • the cleaning agent according to the invention is used as a solid agent, it is common So-called fillers are added, which make up between 10 and 80% by weight of the cleaning agent can.
  • Suitable fillers are e.g. Soda, borax, sulfates and urea.
  • the detergent can also contain an alkaline component can be added, which can be, for example, up to 9% by weight of NaOH.
  • a cleaning agent acidic pH and in this case an inorganic or organic acid is added, the can make up to 25% by weight of the cleaning agent.
  • cumene sulfonate is not among the anionic surfactants can be counted in the form of aromatic sulfonates since the cumene sulfonate has no surfactant effect unfolded.
  • formulations 1, 3 and 4 relate to liquid cleaning agents and formulation 2 solid detergent.
