Definitions
- the present invention relates to readily disintegrating cogranulates with high bulk density made of aluminosilicates and layered crystalline sodium silicates, a process for their preparation and their use.
- phosphates have recently been used in washing and cleaning agents
- Builders especially alkali tri-polyphosphates, are increasingly being replaced by new builder systems, which usually consist of a synthetic, crystalline aluminosilicate (e.g. zeolite A), an alkali source (e.g. soda) and at least a cobuilder.
- a synthetic, crystalline aluminosilicate e.g. zeolite A
- an alkali source e.g. soda
- cobuilders nitrilotriacetic acid or its combination is used individually or in combination Salts, phosphonates or polycarboxylates used
- the synthetic, crystalline aluminosilicate must be used as a very fine powder with an average particle diameter of d 50 ⁇ 10 ⁇ m. If larger agglomerates form during the manufacture of the aluminosilicates, during their processing or in the course of use, the cobuilders mentioned have the task of dividing the aluminosilicates into a suspension of fine primary particles. This is particularly necessary because agglomerates of aluminosilicates - especially zeolite A - do not tend to disintegrate into the primary particles in water.
- US Pat. No. 4,737,306 produces finely divided, water-insoluble phyllosilicates with the oxide sum formula MgO. a M 2 O. b Al 2 O 3 . c SiO 2 . n H 2 O known in which M represents sodium and / or lithium and wherein a, b, c and n each have a number in the ranges 0.05 to 0.4; 0 to 0.3; 1.2 to 2.0 and 0.3 to 3.0 mean.
- These layered silicates which are suitable as detergent raw material in detergents and cleaning agents, are produced by mixing water-soluble sodium silicate with oxides, hydroxides or water-soluble salts of magnesium, aluminum and lithium in aqueous solution or slurry at 150 to 250 ° C. for 1 to 20 hours under autogenous pressure implemented hydrothermally.
- a disadvantage of the known layered silicates containing magnesium and aluminum is that they are water-softening Effect is low. Therefore, their amount must be set high in the formulation, which is because of their Insolubility in water significantly increases the amount of sludge in the sewage treatment plants. Finally, they can be in a builder system not be an alkali supplier.
- cogranulates consisting of aluminosilicates and crystalline sodium silicates with a layer structure, with aluminosilicates of the general formula M 2 / n O. Al 2 O 3 . xSiO 2 .
- yH 2 O are used in which M represents an alkali or alkaline earth metal, n indicates the valence of the cation, x ⁇ 2 and y has a value between 0 and 8, and where the sodium silicates have a SiO 2 / Na 2 O ratio of ( 1.8 to 4.2): 1.
- a process for the preparation of the cogranulates can be characterized in that the aluminosilicates and Sodium silicates mixed in powder form; that the mixture is fed to a zone in which it is between two rollers rotating in opposite directions are compacted under pressure to form a solid; that you crush the solid; and that finally the desired grain sizes of oversize and undersize separates.
- the cogranulates according to the invention can be used in washing and cleaning agents, for example as a builder.
- the crystalline sodium silicates with layer structure contained in the cogranules according to the invention are slowly soluble in water, which means that the sewage treatment plants are relieved of sludge.
- the soda component may be omitted entirely, since the crystalline sodium silicates are an alkali supplier.
- the water-softening effect of the crystalline sodium silicates contained in the cogranules according to the invention is strongly expressed with approx. 75 mg Ca / g (measured in water at 30 ° dH at 20 ° C and pH 10.5).
- Example 3 was repeated with the change that 27 kg of zeolite A and 3 kg of Na 2 Si 2 O 5 with a layer structure ( ⁇ modification) were premixed in the EIRICH mixer: d 50 [ ⁇ m], after 1 min d 50 [ ⁇ m), after 4 min KBV [mgCaCO 3 / g] Bulk density [g / l] 36.8 30.3 181.9 720
