Definitions

  • the paper industry is in constant search of optimization of its manufacturing process, more particularly in terms of yield, productivity, cost reduction and quality of the finished product.
  • the document EP 0 580 529 describes a process for the manufacture of paper and cardboard having improved retention properties in which a terpolymer based on linear amphoteric acrylamide, in the form of a powder in solution, and bentonite is added to the fibrous suspension.
  • bentonite presents an undeniable inconvenience from the point of view of the stationer. Indeed, the industrial bentonite preparation units represent a significant investment as well as heavy maintenance for the paper mills. Bentonite can also present compaction problems due to the ambient humidity around the paper machine, which disrupts the preparation of the bentonite dispersion itself.
  • the cationic polymer described in this document preferably has a cationicity of less than 4 meq.g -1 and the amphoteric polymer has a molar ratio of cationic monomers to anionic monomers of between 5 and 15.
  • composition of such a product is therefore very difficult to guarantee when used in stationery, and can therefore cause more or less marked fluctuations in the operation of the paper machine.
  • the main agent is preferably a cationic polyacrylamide used in a standard manner as a retention agent
  • the secondary and tertiary retention agents are preferably anionic, the tertiary agent being an anionic crosslinked polymer under conventional emulsion form.

These products are well known to those skilled in the art as being in liquid form with a Brookfield viscosity of the order of 5000 cps (LV3 module, 12 rpm -1 , 23 ° C.) at 20% active material. . This type of product therefore has a Brookfield viscosity very much less than 2 cps in a 1M NaCl solution (UL module, 60 rpm -1 , 23 ° C).
  • amphoteric polyacrylamides exemplified in this document were obtained by polymerization in aqueous solution. They are therefore in the form of a liquid in phase with a molecular weight of less than 1.5 million daltons and therefore have a viscosity much less than 2 cps (0.1% in a 1M NaCl solution with Brookfield UL module, speed 60 revolutions per minute, measured at 23 ° C).
  • the document US 8,778,139 refers to a papermaking process for which at least one dispersion of fillers, at least partially “coated” with an amphoteric copolymer, is added to the fibrous suspension in the presence of at least one cationic or amphoteric polymer having no ester functions d 'quaternized amino alcohol.
