Definitions

  • the present invention relates to cleaning agents which are in the form of powder or aqueous Formulation of sodium bicarbonate and polyaspartic acids as dispersants and / or their salts contain the use of these cleaning agents abrasive cleaning of solid surfaces and a method for cleaning with Deposits contaminated surfaces using this detergent.
  • So-called cold cleaners are used to remove impurities of the type mentioned above detached from solid surfaces and transferred into the aqueous phase. From environmentally friendly First generation cold cleaners were required to be quickly detached and detached the pollution and rapid separation of the oil and solvent phases from the water phase and low water solubility of surfactants, emulsifiers and Solvents.
  • the second generation the group of the so-called quick-disconnect Cold cleaner, based on surfactants or surfactant mixtures, the coarsely dispersed water-in-oil Form emulsions that disintegrate relatively quickly.
  • Environmentally friendly cold cleaner The third generation use organic salts due to their chemical nature Structure have a high affinity for hard surfaces.
  • the ability of a detergent is thus a combination of a number of Influences, namely lowering the interfacial tension between an aqueous and an oily phase and influencing the interaction between Particles and wash liquor through penetration and solvation, association, absorption and hydration.
  • Sand is a very hard abrasive material that is effective for Removal of paint or incrustations on metallic surfaces such as steel can be used.
  • silicates for all types of abrasive blasting techniques are very useful, there are also some serious disadvantages.
  • the object of the present invention was to use suitable Detergent to infiltrate, dissolve coverings of the type described above, detach or sand and the dirt as fine as possible in the wash liquor distribute and stabilize iso- and polydisperse.
  • sedimentation processes are important largely in the wash liquor to prevent the lye from to ensure the highest possible dirt load for direct, environmentally friendly disposal to be able to meet the desired application requirements with regard to the dispersion behavior of the waste water. In this way the expense of post-treatment and cleaning of the surroundings can be eliminated or be reduced at least considerably.
  • the object of the present invention is achieved by the combination of sodium bicarbonate dissolved with polyaspartic acids and / or their salts in the cleaning agent.
  • the present invention relates to cleaning agents which are in the form of powder or as an aqueous formulation sodium bicarbonate and as a dispersant polyaspartic acid and / or their salts.
  • the present invention furthermore relates to the use of the invention Detergent for cleaning metallic and non-metallic Surfaces and a method for cleaning this surface.
  • sodium bicarbonate is used as the water-soluble carrier material.
  • Hydrophobized sodium bicarbonate is preferably used, the one easier technical handling guaranteed.
  • the grain size of the sodium bicarbonate is usually chosen so that after Sieve analysis between 10 and 70 wt .-% of the material a grain size between 50 ⁇ and 300 ⁇ , preferably between 170 ⁇ and 280 ⁇ .
  • the content of sodium bicarbonate in the agents is preferably 20 to 95% by weight, in particular 50 to 95% by weight.
  • the dispersants to be used according to the invention are polyaspartic acids and / or their salts used.
  • polyaspartic acids there are primarily polyaspartic acid homopolymers and their salts, as described in WO 96/31 554.
  • the sodium salt and the ammonium salt of polyaspartic acids used as biodegradable and ecologically harmless substances.
  • the anhydride can also of polyaspartic acids, polysuccinimide (PSI) can be used.
  • polyaspartic acids and / or their derivatives are individual or contained in a mixture in amounts of at least 5% by weight.
  • the sodium salt of polyaspartic acids is preferably used in amounts between 5 and 12 wt .-% used in the cleaning agents according to the invention.
  • the cleaner formulation contain more or less water.
  • Such cleaning formulations are preferably selected that show a slight tendency for the cleaning agent to spread and flow hinder.
  • the water content can therefore be freely selected within wide limits.
  • inventive Cleaning agents may contain other additives.
  • additives are primarily Dyes to identify the respective cleaner formulation and preservative to call.
  • the content of such auxiliaries and additives lies in generally not more than 10% by weight, mostly considerably less.
  • a typical frame formulation for abrasive cleaning agents according to the invention is given below.
  • the preparation of the cleaner formulations according to the invention can be done in the simplest way Trap by simply mixing all components in suitable dry mixers respectively. In individual cases, however, it may be more appropriate to use the polyaspartic acids and / or their derivatives as an aqueous dispersion on the carrier material wind up or the carrier material and the polyaspartic acids and / or process their derivatives with water into a suspension and use them in this form to be introduced into the mixing unit.
  • the cleaning formulations 1 to 3 were prepared by mixing the components listed in Table 2. The contents are listed in the table as percentages by weight and are always based on the active ingredient content of the raw materials.
  • example 1 2nd 3rd Sodium bicarbonate 90 0 95 Polyaspartic acid sodium salt 8.8 88 0 Acrylic acid homopolymer 0 0 0 Acrylic acid copolymer 0 0 0 0 Chelating agent 0 0 0 0 Surfactant 0 0 0 Dyes 0.1 0 0 Preservative 1 0.5 0 water to 100 to 100 to 100 to 100
  • Example 2 in Table 3 both in terms of soil-carrying capacity, as well as completely unsatisfactory in terms of cleaning effects shows, the cleaning effect improves in Example 3, whereas that Dirt-bearing capacity remains unsatisfactory.
  • Example 1 shows the best results both in terms of cleaning ability and in terms of of dirt-carrying capacity.
