Definitions

  • organophilically modified layered silicates as rheological additives in organic media.
  • examples of this are the commercial products sold under the names ®Tixogel (manufacturer: Südchemie AG) and ®Bentone.
  • ®Tixogel manufactured by Südchemie AG
  • ®Bentone a commercial product sold under the names ®Tixogel (manufacturer: Südchemie 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 in an organophilic manner is then separated from the water by filtration and dried under the action of heat, for example in a drum dryer at approximately 100.degree.
  • the modified organophilic layered silicates obtained in this way are water-insoluble.
  • the invention thus relates to the use of water-containing organophilic layered silicates, obtained by the reaction of 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 drying by heating, 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 R1 is C8-C22-alkyl or C8-C22-alkenyl, R2 is C1-C4-alkyl and A is an anion, preferably chloride or methosulfate.
  • the compound di-stearyl-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 sheet silicates according to the invention are particularly suitable for coating paper.
  • improvements are being made to use thin printing paper for printed matter with a large circulation, for example for magazines or mail-order catalogs.
  • problems with the opacity ie there is an annoying shine through of the print on the other side of the paper during printing.
  • it is already known (EP 192 252) to coat paper with an organophilic complex 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 the water has been extracted as much as possible by heating.
  • solvent coating suspensions can also contain white pigments (TiO2).
  • TiO2 white pigments
  • these white pigments are well bonded to the paper by the layered silicates; 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.
  • the water-containing organophilic phyllosilicates according to the present invention give a very good hold-out effect.
  • the examples in the table show that conventional white pigments can also be applied to the paper and firmly anchored there by means of the dispersion of the organophil-modified layered silicate in toluene; an additional binder is not required.
