Definitions

  • the invention relates to new cleaning agents with which painted or unpainted surfaces of vehicles, engines, floors in workshops or other work surfaces can be cleaned and degreased, the corresponding contaminants removed being demulsified.
  • the wastewater is not only contaminated with the fats, oils etc. detached from the treated surfaces, but also with organic solvents, especially with chlorinated hydrocarbons, so that it is absolutely necessary to separate the environmentally harmful components from the corresponding wastewater, because is required by law.
  • cold cleaners containing organic solvents have the further disadvantage that flammable, unpleasant odors or even harmful vapors are produced during the cleaning operation, so that the corresponding cleaning operations can only be carried out under extreme precautionary and health protection measures.
  • the first-mentioned detergents containing components with an emulsifying effect have the major disadvantage that fats or grease-like contaminations can be removed from the surfaces to be cleaned, but these contaminations are emulsified in water. It is accepted that either larger amounts of oils, fats or other contaminants get into the wastewater, which is undesirable because of the associated environmental pollution, or additional means for breaking the emulsions formed must be added to separate the organic contaminants To enable oil separators. Apart from economic aspects, however, the subsequent addition of demulsifying agents is associated with further pollution of the water, so that this solution too cannot be satisfactory.
  • DE-A 2 529 096 discloses agents for the cold cleaning of solid surfaces contaminated with fats or grease-like impurities, which essentially consist of aqueous emulsions of ethoxylated phenols having 8 to 20 carbon atoms in the alkyl chain and ethoxylated aliphatic alcohols having 9 to 18 There are carbon atoms in the alkyl chain.
  • the proposed cold cleaners are neutral to weakly alkaline and can be handled safely with good fat dissolving power due to their low or lack of alkalinity.
  • DE-A 2 901 927 proposes cleaning agents for removing oily contaminants which contain fatty alcohol ethoxylates in combination with phenol or lower alkylphenol ethoxylates. During the cleaning operation, the greasy or oily contaminants are removed from the surface to be cleaned in the form of an emulsion. The emulsions formed are relatively short-lived, but it takes hours to break them.
  • the said cleaning agents have such a consistency that they run off directly on vertical surfaces, for example on walls or on the vertical outer surfaces of vehicles, and a longer one Exposure time can only be achieved by adding an agent to increase the viscosity or by treating the surface several times with the cleaner. The surface is therefore not kept in contact with the cleaner for a sufficiently long time, so that repeated application is usually necessary.
  • Such cleaning agents are used to clean various surfaces, for example equipment and containers made of glass or metal, and wall walls, floors or street surfaces which are contaminated with dyes, pigments, fats, proteins, starch derivatives, oils or tar.
  • a cleaning agent formulation is given the following composition: 730 parts of demineralized water, 40 parts of ethylenediaminetetraacetic acid in the form of the sodium salt, 110 parts of nonylphenol polyglycol ether with 10 to ethylene oxide units in 35% strength aqueous solution, 100 parts of mono ethanolamine and 20 parts PLURONIC L 61 (ethylene oxide-propylene oxide block copolymer).
  • AT-A 308 936 describes liquid, storage-stable concentrates and cleaning and degreasing agents which can be prepared from them by dilution with water and are based on a combination of nonionic / fatty acid / alkanolamine in accordance with AT-A 262 474.
  • the new cleaning and degreasing agents are distinguished by the fact that 0 to 100% of the fatty acids in the concentrates are replaced by alkylol polyethylene oxide carboxylic acids, 0 to 100% of the alkanolamines by oxazines, and the nonionic surface-active addition products are present in at least 5% by weight.
  • Such agents ensure good removability of grease and pigment dirt, in particular polishing paste dirt, from metal surfaces.
  • a cleaning agent formulation of the following composition is given: 10% oleic acid, 10% lauryl alcohol-4 EO methane carboxylic acid, 5% aliphatic, primary, straight-chain Ce 20 alcohols + 8 EO, 50% triethanolamine, 2% Ethylenediaminetetraacetic acid, 23% water.
  • US Pat. No. 3,663,445 also relates to liquid, storage-stable concentrates and cleaning and degreasing agents which can be prepared from them by dilution with water and based on a combination of nonionic surface-active substances, alkanolamine salts of fatty acids, alkanolamines and optionally water.
  • These agents preferably contain 3.5 to 15% by weight of fatty acids, 20 to 45% by weight of nonionic surface-active substances and alkanolamines in a molar ratio of fatty acid to alkanolamine equal to 1: 6 to 1:20.
  • Water can contain up to 50% by weight of the concentrates. Furthermore, the agents can contain up to 50% of the total amount of organic solvents.
  • Addition products of 3 to 15 moles of ethylene oxide onto organic compounds with active hydrogen atoms are suitable as nonionic surface-active substances.
  • Agents of this type are used for degreasing and cleaning, in particular, metal surfaces which are contaminated, for example, with oils and pigments.
  • a cleaning agent formulation is given the following composition: 5% oleic acid, 30% nonylphenol + 6 EO, 50% triethanolamine, 1.1% ethylenediaminetetraacetic acid sodium salt, water up to 100%.
  • the object of the present invention was to provide, as an alternative to the agents known from the prior art, those cleaners which can be used without polluting the environment.
  • emulsion formation should be avoided and the use of organic solvents, for example chlorinated hydrocarbons, esters and fractions from mineral oil distillation (petrol, hydrocarbons), should be avoided entirely.
  • organic solvents for example chlorinated hydrocarbons, esters and fractions from mineral oil distillation (petrol, hydrocarbons)
  • the application of the new cleaners should be possible in every way and lead to a lasting wetting of the treated surface.
  • a cleaning effect should also be given at room temperature.
  • increased demands were placed on the biodegradability beyond the legally prescribed level (detergent law, chemical law).
  • cleaners with a good cleaning action and demulsifying properties can be obtained which keep the surface to be cleaned in contact with the cleaning components for a sufficiently long time even without an agent for increasing the viscosity, if aqueous combinations of builders or complexing agents with one or more alkanolamines and one or more nonionic surfactants.
  • the demulsifying cleaning agents according to the invention can optionally additionally add solubilizers in an amount of 1 to 10% by weight and / or corrosion inhibitors for light metals in an amount of 0.15 to 0.25% by weight and / or corrosion inhibitors for non-ferrous metals in an amount of Contain 0.2 to 0.4 wt .-% and / or fragrances and / or dyes in an amount of 0 to 12 wt .-%.
  • the sodium salts of ethylenediaminetetraacetic acid or nitrilotriacetic acid are also preferably used as builders or complexing agents.
  • alkanolamines Another component of the cleaners according to the invention are alkanolamines.
  • a compound of this class of substances or several such compounds can be used in any mixing ratio with one another.
  • diethanolamine, triethanolamine, diisopropanolamine and triisopropanolamine are used as alkanolamines.
  • Compounds of this class of substances are preferably used in amounts of 25 to 50% by weight.
  • the use of the alkanolamine component in an amount below 20% by weight is critical: amounts below 20% by weight, based on the invention aqueous cleaner concentrate would significantly worsen the desired "dampness effect".
  • the demulsifying cleaning agents according to the invention contain nonionic surfactants as a further component.
  • nonionic surfactants as a further component.
  • a single representative of this group of substances or alternatively a mixture of two or more nonionic surfactants can be used, as long as the amount is in the range from 1 to 15% by weight.
  • adducts of 4 mol of ethylene oxide with n- or i-octanol as well as adducts of 2 mol of propylene oxide and 5 to 6 mol of ethylene oxide with the C a -alcohols mentioned are used as nonionic surfactants.
  • the preferred amount of the nonionic surfactants used is in the range of 3 to 6% by weight.
  • Aromatic sulfonates such as cumene sulfonate or butyl glycol sulfonate, are suitable as solubilizers, which can optionally be additionally added to the demulsifying cleaning agents consisting of the above-mentioned components (a), (b), (c) and (d).
  • corrosion inhibitors for light metals for example phosphoric acid
  • corrosion inhibitors for non-ferrous metals for example tolyltriazole
  • the demulsifying cleaning agents according to the invention can also contain fragrances and / or dyes.
  • the cleaners are produced in that the components mentioned are mixed with one another in the respective amounts by methods known per se. Storage or shipping is generally carried out in the form of an aqueous concentrate containing the combination of the specified raw materials, to which the stated amounts (in% by weight) also relate.
  • the demulsifying cleaning agents according to the invention with a moisturizing effect are used in any dilution with water.
  • 3% or more concentrated aqueous solutions are used.
  • the concentrate can even be used.
  • the application takes place in the spray, immersion or high pressure spraying process with appropriate devices.
  • An excellent cleaning result is achieved even at room temperature.
  • the product composition also ensures that the surface to be cleaned is kept moist for approx. 20 to 30 minutes and thus a correspondingly long contact of the cleaning components with the contamination. This is extremely important, for example when cleaning locomotives to achieve a good cleaning result.
  • the demulsifying effect is a decisive advantage compared to conventional products. If, for example, an application solution according to the invention is diluted from 10 to 50% concentration with rinsing water to a concentration of less than or equal to 2% at room temperature, additional mineral oil which has been introduced separates practically completely from the solution when it is at rest for 30 minutes. With appropriate waste water collection containers, the oil content of waste water can be reduced to less than 50 mg 1-1 solely by such mechanical oil separation.
  • iron (11) sulfate or aluminum sulfate to the wastewater to further reduce the oil content and thereby achieve a flocculation of the contaminants.
  • the residual oil content in the waste water can be reduced to a value below 10 mg 1-1.
  • the comparative cleaner therefore contained a strongly emulsifying surfactant.
  • the product film remaining on the cleaned parts after the treatment also offers - in addition to keeping them moist - the necessary temporary corrosion protection. This is particularly important when cleaning the engine compartment.
  • the storage corrosion protection test was carried out according to the so-called "plate climate test”. Steel sheets of quality ST 1405 were cleaned with trichlorethylene and then immersed in 10% solutions of the cleaners according to the invention. After 5 minutes the sheets were removed and dried at room temperature. The sheets were stored in a climate box at 23 ° C and 100% relative humidity. Sheets treated in this way showed no signs of corrosion even after 14 days.
