Definitions

  • Powdered zeolite type A which can be used as a phosphate substitute in detergents, is a lumpy powder which tends to agglomerate due to its small particle size. It is difficult to mix this zeolite powder with the other detergent components to form a homogeneous powder. The fact that the finished mixture tends to segregate again makes it difficult.
  • zeolite granules are added to the already spray-dried detergent components. These zeolite granules are produced by spray drying an aqueous suspension of the zeolite powder with the addition of further detergent components.
  • Spray-dried beads are known from FR-A 2 500 474, which contain.
  • the component according to formula 1 can be crystalline.
  • An aluminum silicate can preferably be used as the component according to the formula.
  • y can be a number from 1.3 to 4.
  • the crystalline component according to formula 1 can be a type A zeolite.
  • the aluminum silicates according to formula I can be naturally occurring or else synthetically produced products, the synthetically produced products being used in the present invention. They can be prepared, for example, by reacting water-soluble silicates with water-soluble aluminates in the presence of water. For this purpose, aqueous solutions of the starting materials can be mixed with one another or a component present in the solid state can be reacted with the other component present as an aqueous solution.
  • the desired aluminum silicates are also obtained by mixing both components in the solid state in the presence of water.
  • Aluminum silicates can also be produced from Al (OH) 2 , Al 2 O 3 or S10 2 by reaction with alkali silicate or alkali aluminate solutions. The production can also be carried out by other known processes.
  • the invention relates to aluminum silicates which have a three-dimensional space lattice structure.
  • the preferred calcium binding capacity which is approximately in the range from 100 to 200 mg CaO / g AS, usually around 100 to 180 mg CaO / g AS, is found above all in compounds of the composition:
  • the crystalline aluminum silicate present in aqueous suspension can be separated from the remaining aqueous solution by filtration and dried. Depending on the drying conditions, the product contains more or less bound water.
  • the aluminum silicates do not need to be dried at all after their preparation in order to prepare the detergent builders according to the invention; rather, an aluminum silicate that is still moist from manufacture can be used, and this is particularly advantageous.
  • the particle size of the individual aluminum silicate particles can be different and e.g. are in the range between 0.1 ⁇ m and 0.1 mm. This refers to the primary particle size, i.e. the size of the particles obtained during the precipitation and, if appropriate, the subsequent crystallization. It is particularly advantageous to use aluminum silicates which consist of at least 80% by weight of particles with a size of 10 to 0.01 ⁇ m, in particular 8 to 0.1 ⁇ m.
  • These aluminum silicates preferably contain no primary or. Secondary particles more with diameters above 45 ⁇ m. Secondary particles are particles that are formed by agglomeration of the primary particles into larger structures.
  • powdered zeolite of type A with a particularly defined particle spectrum is used as component A.
  • Such zeolite powder can according to DE-AS 24 47 021, DE-AS 25 17 218, DE-OS 26 52 419, DE-OS 26 51 420, DE-OS 26 51 436, DE-OS 26 51 437, DE-OS 26 51 445 or DE-OS 26 51 485 can be produced. They then have the particle distribution curves given there.
  • a powdery zeolite of type A can be used, which has the particle size distribution described in DE-OS 26 51 485.
  • Bentonite is known as a detergent component (cf. Tenside Detergents 22 (1985) 2, pages 57 to 66).
  • a bentonite is used, which is characterized by the following parameters:
  • Addition products of 4 to 40, preferably 4 to 20 moles of ethylene oxide with 1 mole of fatty alcohol, alkylphenol, fatty acid, fatty amine, fatty acid amide or alkanesulfonamide can be used as nonionic surfactants.
  • the addition products of 5-16 mol of ethylene oxide with coconut oil or tallow fatty alcohols, with oleyl alcohol or with secondary alcohols with 8-18, preferably 12-18, carbon atoms, and with mono- or dialkylphenols with 6-14 carbon atoms in the alkyl radicals are particularly important .
  • the adduct of 5 moles of ethylene oxide with tallow fatty alcohol is of particular interest.
  • polyglycol ethers with 1-4 ethylene glycol ether residues in the molecule that are not or not completely water-soluble are also of interest, especially when they are used together with water soluble nonionic or anionic surfactants can be used.
  • non-ionic surfactants that can be used are the water-soluble adducts of ethylene oxide with polypropylene glycol, alkylene diamine polypropylene glycol and alkyl polypropylene glycols with 1-10 carbon atoms in the alkyl chain, in which the polypropylene glycol chain acts as a hydrophobic chain, in which the polypropylene glycol chain acts as a hydrophobic chain.
  • Non-ionic surfactants of the amine oxide or sulfoxide type can also be used.
  • nonionic surfactant is a mixture of at least two different fatty alcohol ethoxylates based on isotridecyl alcohol or an aliphatic C 3 alcohol and ethylene oxide. This mixture can preferably consist of fatty alcohol ethoxylates with 4.5 to 5.5 EO and fatty alcohol ethoxylates with 6 to 8 EO. A mixture of at least two different alkylphenol ethoxylates of the formula can also be used as the nonionic surfactant be used.
  • R can be an aliphatic radical with 1 to 15, for example -CH 3 , -C 2 H 5 , propyl, butyl, pentyl, hexyl, heptyl-octyl and nonyl, preferably with 9 C atoms such as nonyl.
  • the rest R can be substituted in the ortho, meta and / or para position.
  • Mixtures can also be used in which an o-substituted benzene ring is present in addition to p-substituted aryl ring. Mixtures are used in which there is 90% p substitution and 10% ortho substitution.
  • n can mean 2 to 7, preferably 4 to 6, in particular 5 in the case of one alkylphenoethoxylate used in the mixture and 8 to 15, preferably 8 to 12, in particular 9 or 10 in the other alkylphenolethoxylate. n can also mean 7 or 9 or 12 in the case of mixtures of the alkylphenolates.
  • alkylphenol ethoxylates and the isotridecyl alcohol ethoxylates can each be used in any mixture, preferably in a ratio of 1: 9 to 9: 1, preferably 2: 3 to 3: 2, in particular 0.9: 1.1 to 1.1: 0.9 will.
  • NaOH and / or KOH can be used as alkali.
  • the granular detergent builder according to the invention can be prepared by mixing the individual components with one another, setting a consistency suitable for spray drying by measuring the amount of water and spray-drying the suspension thus obtained by known methods.
  • the granulated detergent builder according to the invention is stable in transportation, easy to redisperse and extremely low in dust.
