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. This is aggravated by the fact that the finished mixture tends to segregate again.
- 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.
- a spray-dried powder component is known from European published patent application EP-OS 0114308, which consists of 60 to 80% by weight of aluminosilicate, 2 to 10% by weight of sodium sulfate, 1 to 5% by weight of a nonionic surfactant, 0 to 8% by weight. -% of a polyphosphonic acid and 10 to 25 wt .-% water.
- an insoluble detergent builder which is characterized in that it contains easily disintegrating agglomerates of finely divided zeolite particles with ion exchange properties, which are held together by a binder, the particle size of the agglomerates being in a range corresponding to a mesh number from 4 to 180.
- Carboxymethyl cellulose and methyl cellulose can be used as binders.
- the invention relates to a granulated detergent builder consisting of:
- the component according to formula I can be crystalline.
- the component of the formula (an aluminum silicate can preferably be used.
- 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 synthetically produced products, with the synthetically produced products being preferred.
- the preparation kkann example by - carried by water reaction of water-soluble silicates with water-soluble aluminates in the presence.
- 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 0 3 or Si0 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:
- This molecular formula comprises two types of different crystal structures (or their non-crystalline precursors), which also differ in their molecular formulas. They are:
- 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 no longer contain primary or secondary particles with diameters above 45 ⁇ m.
- Secondary particles are particles that are formed by agglomeration of the primary particles into larger structures.
- the use of the aluminum silicates which are still moist from their production for the production of the detergent builders according to the invention has proven particularly useful since it has been found that the formation of secondary particles is practically completely prevented when these still moist products are used.
- 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.
- 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 adducts 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 C atoms, and with mono- or dialkylphenols with 6-14 C atoms in are particularly important the alkyl residues.
- the adduct of 5 moles of ethylene oxide with tallow fatty alcohol is of particular interest.
- non-or not completely water-soluble polyglycol ethers with 1-4 ethylene glycol ether residues in the molecule are also of interest, in particular if they are used together with water-soluble nonionic or anionic surfactants.
- the water-soluble adducts of ethylene oxide with polypropylene glycol, alkylenediamine-polypropylene glycol and alkylpolypropylene glycols with 1-10 C atoms in the alkyl chain, in which the polypropylene glycol chain functions, are useful as nonionic surfactants, the addition products containing 20-250 ethylene glycol ether groups and 10-100 propylene glycol ether groups.
- Nonionic 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 13 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 -CH3, --C 2 H 5 , propyl, butyl, pentyl, hexyl, heptyl, octyl and nonyl, preferably with 9 C atoms such as nonyl.
- the radical R can be substituted in the ortho, meta and / or para position.
- Mixtures can also be used in which, in addition to p-substituted aryl ring, o-substituted benzene ring is also present. 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 alkylphenol ethoxylate used in the mixture and 8 to 15, preferably 8 to 12, in particular 9 or 10 in the other alkylphenol ethoxylate.
- n can also mean mixtures of the alkylphenolates in each case 7 or 9 or 12.
