  • the latex used is the natural latex.
  • the latex used is an artificial latex (chlorobutadiene polymer or acrylic latex in particular).
  • the latex solution used has a solids content of between 5 and 50%, and preferably between 7 and 15%, its viscosity (Brookfield) is between 30 and 650 centipoise at 25 °, and the amount of latex is between 3 and 75% (as dry product) based on the total dry weight of fibrous materials).
  • the diameter of the divided latex particles is between 0.01 and 0.5 g and preferably between 0.1 and 0.2 g.
  • the polyelectrolyte solution used has a solids content of between 0.2 and 10%, and the amount introduced into the suspension of fibrous materials is between 0.1 and 3.5% of the dry product relative to the total dry weight of the latex for the first addition and between 0.1 and 2% of the dry product relative to the dry weight total of fibrous materials, for the second addition.
  • the antifoam solution has a solids content of between 2 and 20%, and the amount added to the total mixture is between 0.05% and 0.25% of the total dry weight of fibrous materials.
  • the pH is adjusted using hydrochloric acid and / or sulfuric acid and / or alumina sulphate.
  • the phenolic resin (or aminoplast) solution has a content of about 50 to 85% solids, a viscosity (Brookfield) of between 5,500 and 7,000 centipoise, and the amount added to mixture (dry product) is between 0.01 and 50% based on the total dry weight of the fibrous materials.

  • the present invention also relates to sheets of fibrous materials obtained according to the process according to the invention.
  • the paper thus obtained and which can be used for many industrial purposes (abrasive paper, adhesive paper, tearproof papers for bags, posters, etc ..., papers for the preparation of artificial leather, paper for book covers, envelopes papers waterproof, papers for the manufacture of bags for vacuum cleaners, etc )., has excellent mechanical characteristics which rank it among the best, and this thanks, in particular to its breaking length, its resistance to burst, its tensile strength, at its aptitude for thermoforming, its high resistance to use in an aqueous medium, its resistance to repeated bending, etc.
  • Another extremely important characteristic of the paper according to the invention is its homogeneity demonstrated by the electron microscope and which clearly differentiates it from all the other papers currently on the market.
  • the present invention relates to the reuse and recovery of fibrous materials obtained according to the method described.
  • One of the advantages and not least of the process according to the present invention resides in the possibility of relatively easily recycling any fibrous material obtained according to the present invention, and this in contrast to all the papers containing latex and prepared according to the methods of the prior art.
  • This repulpability and recycling operation is characterized in that it is carried out in an aqueous medium, cold, in the presence of a wetting agent and in the presence of a small amount (0.01 to 0.15% relative to volume of water and 0.2 to 1.5% based on the weight of dry fibrous materials) chloride ions and / or sulfate ions and / or sulphamate ions. It is of course the extremely fine crosslinking of the latex molecules on the fibrous material which explains the easy repulbability of the papers prepared in accordance with the present invention.
  • the present invention is particularly directed to the process and the installations for producing sheets of fibrous materials (and in particular paper) containing, in their bulk, latex or the like and / or phenoplasts or aminoplasts and sheets of fibrous materials as well as obtained, as well as the means specific to the implementation of these methods, as well as the overall processes and the production lines in which are included the methods and facilities according to the present invention.
  • the fibrous material from a pulp mill is introduced into the tank 1 in the presence of water and coloring matter if necessary, and undergoes appropriate agitation therein to suspend the fibrous particles.
  • the solids content of the mixture is adjusted to about 2.5%.
  • the prepared fibrous suspension is conveyed into the storage tank 2, then into the so-called section 3 of refining and hydration of the fiber, so that the fibrous material undergoes the structural modifications necessary for subsequent sheet setting.
  • the structural modification must give the mixture a freeness value according to the SCHOPPER-RIEGLER method, between 10 and 50 ° SR.
  • the fibrous material thus prepared is then introduced into the mixing tank 8.
  • the treatments in sections 23 and / or 24 are optional, but these additional operations may provide properties for particular uses. If sections 23 and / or 24 are not used, the sheet is fed directly into section 25 where it is wound into a reel.
  • This sheet of paper is prepared in a con tinue, as described in Example 1, however without passing through section 16, but with the passage in section 23 for calibration, then directly to section 25.
  • This paper is prepared with passage in sections 16 -> 22 -> 23 -> 25.
  • This paper is prepared according to the method described in Example 1, with a direct passage from section 15 to section 25.
  • This paper is prepared according to the method described in Example 1, with the passage in sections 16 -> 22 -> 25.
  • This paper is prepared as described in Example 6.
  • Example 8 Preparation of a paper with a release layer
  • an aqueous solution is prepared containing about 20% (expressed as dry matter) of previously stabilized polyester emulsion at pH 5.4, an emulsion whose Brookfield viscosity (at 25 ° C.) is between 200 and 1. 000 centipoises.
  • the dry extract of the solution contained in the tank is between 2 and 8%.
  • the agitator 102 is turned on and stirred until about 80% of the paper is disintegrated. This disintegration is verified by the control methods usual in stationery. At this stage, there are still some very fine agglomerates called in paper jargon "buttons" or "pellets". the mixture thus obtained is then passed into a disintegration apparatus 105, called “de-tater” (for example, "Hydraflaker” brand de-spatter produced by BLACK CLAWSON), by recycling the juice via the pipework 105 to the tank 101 .
  • de-tater for example, "Hydraflaker” brand de-spatter produced by BLACK CLAWSON
  • the repulpability time in the tank 101 was 25 minutes, the break-up time 15 minutes, for a total of 40 minutes to make reusable the 500 kg of the fibrous material, directed to reuse by the pipe 104.
  • Example 10 Recovery of used paper with a very high latex content
  • composition of the starting paper is Composition of the starting paper:
  • the procedure is as described in Example 2, but 0.15% bleach p / volume is introduced.
  • the disintegration time was 40 minutes and the peeling time 15 minutes, ie 55 minutes for the 500 kg of material used.
  • the raw material thus recovered is reused in a conventional printing-writing medium production at a rate of 10% of dry product relative to the total dry weight of the support manufactured.
  • Table 1 summarizes the mechanical characteristics and Table II shows the characteristics of a paper in which a recycled pulp fiber material was used:
  • the papers obtained according to the method according to the present invention not only have excellent physical strength, but their ability to print coated sheets is quite good, both in exposure and in ink, clarity and rendering. colors.
