Definitions

  • the invention relates to a powder detergent defoamer, the process for its preparation and its use as a defoamer in detergents.
  • EP-OS 142 910 describes a detergent defoamer which consists of a mixture of polydimethylsiloxane with a viscosity of 20 to 12,500 cs and polydimethylsiloxane with a viscosity of at least 25,000 cs and hydrophobic silicon dioxide.
  • This defoamer can additionally contain a solid, water-soluble, inorganic carrier substance such as sodium tripolyphosphate or aluminum silicate. Before being used, the defoamer is dispersed in an organic carrier system which consists of a mixture of high-melting nonionic surfactants.
  • the known defoamer has the disadvantage that its shelf life is limited because the defoamer activity decreases with increasing storage time.
  • the invention relates to a powder detergent defoamer consisting of 65 to 99.9% by weight, preferably 85 to 96% by weight of a carrier and 0.1 to 35, preferably 5 to 15% by weight of a silica-containing silicone oil defoamer.
  • the powder detergent defoamer consists of 85-96% by weight of powdered type A zeolite as carrier 3 - 9% by weight of low viscosity silicone oil 1 - 5% by weight of highly viscous silicone oil 0.5-1.5% by weight of hydrophobic precipitated silica
  • the zeolite A in the form of a zeolite compound can be used as the carrier.
  • Zeolite compounds are known. They are commercially available as a builder component for detergents.
  • Another object of the invention is a process for the preparation of the powder detergent defoamer, which is characterized in that the low-viscosity silicone oil is mixed with vigorous stirring with the hydrophobic precipitated silica and then the highly viscous silicone oil is mixed in, the mixture thus obtained with the powdered zeolite of the type A is converted into the powder form in a mixing device.
  • a powdery zeolite of type A with a particularly defined particle spectrum is used.
  • 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, DE-OS 26 51 485 are 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-PS 26 51 485.
  • the silicone oil is an organopolysiloxane liquid of the general formula wherein each R may be the same or different radicals which are selected from optionally substituted monovalent hydrocarbon radicals, such as aliphatic, halogenaliphatic and cyclo-aliphatic radicals, e.g. B. alkyl, alkenyl, Cycloalkyl, haloalkyl, such as methyl, ethyl, propyl, chloroethyl, trifluoropropyl, phenyl, tolyl, benzyl or OH or halogen, where a is a number sufficient to achieve the viscosity mentioned above. Dimethylpolysiloxanes are preferably used.
  • Sipernat® D10 can be used as the hydrophobic precipitated silica.
  • Sipernat® D10 is a precipitated silica that has been made hydrophobic by post-treatment with a silicone oil. Such an aftertreatment method is used e.g. B. described in DE-OS 26 28 975.
  • Sipernat D 10 is a commercially available precipitated silica that has the following physico-chemical characteristics: Sipernat® D 10 Surface according to BET 1) m2 / g 90 Average size of the primary particles nm 18th Tamped density 2) g / l 100 pH 3) 10.3 8) Sieve residue (according to Mocker 45 ⁇ m) 4)% 0.01 Loss on drying (2 h, 105 ° C) 5)% 3rd Loss on ignition (2 h, 1000 ° C) 5) 6)% 7 9) SiO2 7)% 98 Na2O 7)% 0.8 Fe2O3 7)% 0.03 SO3 7)% 0.8 1) according to DIN 66 131 2) according to DIN 53 194 (not screened), ISO 787 / XI or JIS K 5101/18 3) according to DIN 53 200 (in 5% aqueous dispersion) ISO 787 / IX, ASTM D 1208 or JIS K 5101/24 4) according to DIN 53 580
  • B. spray mixing units such. B. free fall mixer or ploughshare mixer, such as. B. Lödige mixer use.
  • the powder detergent defoamer according to the invention has the advantage that it has excellent storage stability in detergents and good flow properties.
  • Wessalith® P is a powdery zeolite A according to DE-PS 26 51 485.
  • CMC is carboxymethyl cellulose.
  • Wessalith® CS, Wessalith® CN and Wessalith® CD are Zeolite granules (compounds) that can be processed with other ingredients to form detergent mixtures.
  • the composition of the individual zeolite granules is listed in Table 1.
  • the examples show the test of the defoaming behavior of the defoamer according to the invention on the basis of Sipernat® D 10, Silicone oil mixture of two silicone oils with a viscosity of 1,000 and 60,000 cst and different carriers.
  • the silicone oils are designated with DC 200/1000 cst or DC 200/60000 cst.
  • Phosphate, sulfate, starch, CMC, soda and WESSALITH® P, -CS, -CN and -CD are used as carriers.
  • the defoaming behavior was tested after storage for 2, 4 and 8 weeks under critical conditions (35 ° C and 70% relative air humidity).
  • Figures 1 to 9 show the defoaming behavior of the respective foam inhibitor concentrates. - after production (defoamer picture top left) - after two weeks of storage in detergent (defoamer picture top right) - after four weeks of storage in detergent (defoamer picture bottom left) - after eight weeks of storage in detergent (defoamer picture bottom right)
  • the silicone oil Dow Corning® Fluid DC 200 Fluid with a viscosity at 25 ° C of 1,000 cst was used as the low-viscosity silicone oil.
  • the silicone oil Dow Corning Fluid DC 200 Fluid with a viscosity of 60,000 cst at 25 ° C was used as the highly viscous silicone oil.
  • SIPERNAT® D 10 is added to the low-viscosity silicone oil with intensive stirring (Ultra-Turrax, dispersion time 5 min at 11,000 U). Then the respective amount of highly viscous silicone oil is added.
  • a detergent of the following composition is used as the detergent: Bandwidth in particular Nonionic surfactants 2 - 5 4th Anionic surfactants 7-10 9 polymer 2 - 5 4th Zeolite A 20-30 29 Sodium silicate 4 - 9 7.5 Sodium carbonate 6-10 8.5 CMC 1 - 2.5 2nd Sodium sulfate 15-25 21st water 7-17 15 %
