Definitions

  • the invention relates to a process for the preparation of a phosphate-free, pourable defoamer granulate for use in detergents and cleaning agents, containing inorganic, water-soluble or water-dispersible carrier salt, water-insoluble organopolysiloxane and a mixture of alkali metal carboxymethyl cellulose and nonionic cellulose ether.
  • foam control agents consist of powdered or granulated sodium tripolyphosphate which has an organopolysiloxane-containing defoamer on its surface. These agents are produced by simply mixing the phosphate carrier material, which is used in particular as prefabricated anhydrous granules, with the organopolysiloxane component, which is used in particular in the form of an aqueous emulsion. Because of their high phosphate content, such agents are obsolete for use in modern washing or cleaning agents.
  • German published patent application DE 24 02 955 proposes using a free-flowing, powdery or crystalline sodium perborate as the carrier material for organopolysiloxanes instead of the tripolyphosphate mentioned above.
  • British patent application GB-A-2 009 223 relates to detergents which contain polymeric silicones as foam-suppressing components.
  • a manufacturing process for silicone-containing defoamer granules is disclosed there, which has the parameters 1. Preparation of a mixture of silicone and emulsifier, which can be a cellulose ether, 2. a) heating this mixture until it melts or 2. b) liquefying the mixture by adding water , 3. Has granulating mixing of the liquid silicone mixture with carrier material.
  • Solid detergents are known from European patent application EP 0 008 829, which contain a foam control system made of wax, hydrophobized silica gel, certain nonionic dispersants and optionally silicones, which is present in an intimate mixture with the other detergent components.
  • the previously liquefied foam control system can be sprayed onto a prefabricated, in particular spray-dried carrier grain which contains all or part of the other detergent components.
  • Such a manufacturing process is relatively complex due to its multiple stages.
  • German patent application DE 34 36 194 discloses a process for the preparation of pourable defoamer granules by spray drying an aqueous dispersion which contains water-insoluble defoamers, inorganic carrier salt and certain cellulose ether mixtures. Such a process can lead to products which do not have optimal defoamer performance in all cases due to the thermal stress under spray drying conditions, especially when using organopolysiloxanes.
  • the task was to develop a stable defoamer preparation that survives the mixing process with the other powdered detergent or cleaning agent components without destroying their granular structure and without dust formation, and yet dissolves quickly and without residue under use conditions and the foam-inhibiting active ingredient releases.
  • the process according to the invention for the production of pourable defoamer granules by build-up granulation in a granulation mixer which contains a water-insoluble defoamer from the class of organopolysiloxanes, cellulose ethers and inorganic, water-soluble or water-dispersible carrier salt is characterized in that the build-up granulation is carried out in such a way that an amount of 80 up to 200 parts by weight of a phosphate-free carrier salt mixture containing alkali sulfate and alkali carbonate and optionally up to 70 parts by weight of alkaline earth metal silicate, with an amount of up to 8 parts by weight of a mixture of alkali carboxymethyl cellulose and nonionic cellulose ether in a weight ratio of 80:20 to 40:60 Adds up to 16 parts by weight of water to continuous granulation until the end of production, and then adds 5 to 30 parts by weight of a liquid organopolysiloxane.

Abstract

L'invention a pour but d'obtenir une préparation anti-mousse d'une grande efficacité, exempte de phosphates et apte à l'écoulement, selon un procédé aussi économique que possible, tout en s'efforçant de réaliser le mélange des constituants détergents en poudre habituels sans destruction de leur structure granulaire et sans dégagement de poussière, ladite préparation devant en outre se dissoudre rapidement et sans résidus dans les conditions d'emploi. Ce but est atteint grâce au fait qu'on effectue, dans un mélangeur à granulation, une granulation de structure en mélangeant à fond une quantité de 80 à 200 parties en poids d'un mélange de sel-support contenant un sulfate alcalin et un carbonate alcalin, avec une quantité allant jusqu'à 8 parties en poids d'un mélange d'éther cellulosique, en ajoutant une quantité allant jusqu'à 16 parties en poids d'eau, tout en effectuant la granulation jusqu'à la fin de la fabrication, puis en ajoutant une quantité de 5 à 30 parties en poids d'un organopolysiloxane liquide.
