- PROCESS FOR PRODUCING PAPER AND CARDBOARD NEW CORRESPONDING RETENTION AND DRIP AGENTS AND THE PAPER AND CARDBOARD THUS OBTAINED
- the invention relates to a process for the production of paper, cardboard or the like using at least three retention and draining agents, respectively a main agent, one or even two secondary agents and a tertiary agent. It also relates to the paper or cardboard obtained by this process. Finally, it relates to the use of specific crosslinked anionic organic polymers as a tertiary retention agent.
- Microparticulate retention systems are well known in the papermaking process. Their function is to improve retention, drainage and training during the manufacture of the sheet.
- microparticles anionic or cationic
- the size of the organic microparticles is a direct indication of the power of particle agglomeration and therefore of retention (by allowing, in particular, to increase the availability of loaded, anionic or canonical sites).
- Patent EP-A-462365 which also relates to the use of a polymer (main retention agent) and an organic microparticle (secondary retention agent) , characterized in that the average size of the microparticle must be less than 750 nm
- WO 02/33171 proposes, in the same line as the patent cited above (p.7, 1.16+), the use in addition to the cationic organic polymer (main retention agent), an inorganic particle (secondary retention agent) and an anionic organic particle (tertiary retention agent) which must be less than 750 nm in size.
- a polymer obtained by reverse phase polymerization of a water-soluble anionic monomer, in the presence of a crosslinking agent, the level of which is between approximately 6 and 25 ppm molar, in the absence of transfer agent, is necessarily reticle.
- a crosslinking agent content of less than 6 ppm molar and in the absence of transfer agent the anionic polymer obtained is branched, while in the range of 6 to 25 ppm molar, the presence of transfer agent is necessary to obtain a branched polymer.
- the subject of the invention is therefore a process for manufacturing cardboard paper or the like which consists in: - firstly adding to the fibrous suspension at least one main retention agent consisting of a cationic (co) polymer, - then optionally shearing the flocs obtained, the process being characterized in that one then adds to the suspension, separately or as a mixture, in one direction or the other: at least one secondary retention agent chosen from the group comprising derivatives of silica and anionic or amphoteric organic polymers, at least one tertiary retention agent consisting of a crosslinked anionic organic polymer, of size greater than or equal to 1 micrometer and having an intrinsic viscosity less than 3 dl / g.

- a single secondary retention agent consisting of one or more silica derivatives, advantageously bentonite, is added to the suspension.
- the tertiary retention agent is added separately, at the same point or at a separate point, before or after the secondary agent.
- a single secondary agent means that said agent may contain several products provided that they are of the same nature. This is for example the case when the secondary agent consists of one or more silica derivatives.
- a single secondary retention agent consisting of one or more anionic or amphoteric organic polymers different from the tertiary retention agent is added to the suspension.
- the secondary and tertiary retention agents can constitute a mixture, which is then injected at a point. This will generally be the case when the two products are in compatible physical forms.
- two secondary retention agents are added to the suspension, respectively one or more silica derivatives and one or more anionic or amphoteric organic polymers different from the tertiary retention agent.
