Definitions

  • the polymeric silicic acid was prepared from water glass (Na2O.3.3SiO2) which was diluted with water to an SiO2 content of 5 per cent by weight.
  • the aqueous solution was ion exchanged with ion exchange resin Amberlite IR-120 to a pH of 2.3.
  • the specific surface area of the obtained acid polymeric silicic acid was measured by titration according to the method given earlier and was found to be 1450 m2/g.

Claims (9)

  1. Procédé de production de papier à partir d'une suspension de fibres contenant de la cellulose, et de charges éventuelles, dans lequel on ajoute à la suspension un polymère cationique et une substance minérale anionique, et la suspension est mise en forme et épaissie sur une toile métallique, procédé caractérisé en ce que l'on ajoute à la suspension de fibres un polyacrylamide cationique, un amidon cationique et un acide silicique polymère qui présente une aire spécifique d'au moins 1050 m²/g.
  2. Procédé conforme à la revendication 1, caractérisé en ce que l'acide silicique polymère présente une aire spécifique située dans l'intervalle allant de 1100 à 1700 m²/g.
  3. Procédé conforme à la revendication 1 ou 2, caractérisé en ce que l'acide silicique polymère est un acide silicique polymère que l'on a préparé par acidification d'un verre soluble d'un métal alcalin à un pH situé dans l'intervalle allant de 1,5 à 4.
  4. Procédé conforme à la revendication 1, 2 ou 3, caractérisé en ce que l'acide silicique polymère a été préparé par acidification au moyen d'un échangeur de cations sous forme acide.
  5. Procédé conforme à l'une quelconque des revendications précédentes, caractérisé en ce que l'acide silicique polymère est ajouté à raison d'au moins 0,01 g/kg (kg/t), quantité calculée en SiO₂, par rapport aux fibres sèches et aux charges éventuelles.
  6. Procédé conforme à la revendication 1, caractérisé en ce que le rapport pondéral de l'amidon cationique et du polyacrylamide cationique à l'acide silicique polymère, exprimé en SiO₂, vaut plus de 0,1/1.
  7. Procédé conforme à la revendication 1, caractérisé en ce que le rapport pondéral de l'amidon cationique au polyacrylamide cationique se situe dans l'intervalle allant de 0,5/1 à 200/1.
  8. Procédé conforme à la revendication 1, caractérisé en ce que l'amidon cationique est ajouté à la suspension de fibres avant le polyacrylamide cationique et l'acide silicique polymère.
  9. Procédé conforme à l'une quelconque des revendications précédentes, caractérisé en ce que les fibres contenues dans la suspension comprennent au moins 25% en poids de fibres provenant d'une pâte mécanique et/ou d'une pâte de fibres recyclées.
