Definitions

  • organophilically modified layered silicates as rheological additives in organic media.
  • examples of this are the commercial products that are sold under the names ®Tixogel (manufacturer: Süd-Chemie AG) and ®Bentone.
  • These rheological additives create a thixotropic structure in organic media, for example in paints and varnishes.
  • the organophilically modified layered silicates are obtained by treating layered silicates in aqueous suspension with an aqueous solution of an onium compound, preferably a quaternary organic ammonium salt, this organic ammonium salt being incorporated between the layers of the layered silicate.
  • the layered silicate modified in this way is then separated from the water by filtration and dried under the action of heat, for example in a drum dryer at approximately 100 ° C.
  • the modified organophilic layered silicates obtained in this way are water-insoluble.
  • EP-A-0 279 313 relates to a process for the preparation of an agent which is suitable for the paper and board industry and which improves the printability of paper and board, characterized in that starting from at least one pigment and at least one water-soluble or water-swellable anionic groups Hydrogel prepares an aqueous colloidal system, subjects it to coacervation using a quaternary organic ammonium salt and, if appropriate, concentrates the product obtained during the coacervation. These agents are used to produce a paper or cardboard coating slip and as a filler for mixing into a paper raw material.
  • the invention thus relates to the use of water-containing organophilic layered silicates, obtained by reacting a layered silicate which is completely delaminated in water and is cation-exchangeable an organic onium salt in aqueous suspension and subsequent mechanical separation of the water without subsequent drying, as a rheological additive in organic media and for coating paper.
  • organophilic layered silicates are obtained by methods known per se, which therefore need not be explained in more detail.
  • All synthetic or natural smectic layer silicates preferably bentonite or montmorillonite, which can contain 25-30% by weight of impurities in the form of other minerals in addition to a smectic layer silicate, are suitable as cation-exchangeable layer silicates which are completely delaminated in water.
  • the minerals are treated with an aqueous solution of onium compounds, such as phosphonium compounds, but preferably quaternary organic ammonium salts, these compounds being embedded between the layers of these minerals.
  • Suitable quaternary organic ammonium salts are, in particular, compounds of formula where R 1 is C 8 -C 22 alkyl or C 8 -C 22 alkenyl, R 2 C 1 -C 4 alkyl and A is an anion, preferably chloride or methosulfate.
  • the compound distearyl-dimethyl-ammonium chloride is particularly preferred.
  • Organic media in the sense of this invention are, for example, paints, lacquers, Paints, putties, greases, cosmetics, paint strippers, fillers and similar preparations containing organic solvents.
  • the water-containing organophilically modified layered silicates according to the invention have a thixotropic effect. This effect makes the preparations mentioned easier to process.
  • these layered silicates also prevent the insoluble components from settling, e.g. of the pigments within these media.
  • it was found in these water-containing organophilic layered silicates that the thickening effect is significantly higher in comparison to the analog commercial products with the same solids content, but from which the water was removed by drying with heating.
  • the water-containing organophilic layered silicates according to the invention are particularly suitable for coating paper.
  • efforts are being made to use thin printing papers for printed matter with a large circulation, for example for magazines or mail-order catalogs.
  • this gives rise to problems with regard to opacity, that is to say when printing there is an annoying shine through of the print on the other side of the paper.
  • it is already known (EP-A-192 252) to coat paper with an organophilic complex composed of a smectic layered silicate and a quaternary organic ammonium compound from a suspension in organic solvents.
  • the starting material is in a form that was largely removed from the water by heating.
  • solvent coating suspensions can also contain white pigments (TiO 2 ).
  • TiO 2 white pigments
  • the organophilically modified layered silicates bind these white pigments well on paper; an additional binder is therefore not required. In this way, a good hold-out effect is obtained, ie prevention of strikethrough on the printed paper.
