Definitions

  • the present invention relates to a new process for the continuous production in an aqueous medium of sheets of fibrous materials - and in particular paper - containing latex in their mass.
  • the invention also relates to the sheets of fibrous material which can be obtained using this method.
  • the object of the present invention is therefore to provide a new process for the continuous production of this latex-containing fibrous material, which better meets the needs of the practice than the methods aiming at the same object previously known, in particular in that it not only eliminates a whole series of coating steps by making paper from fibrous materials containing latex perfectly bonded to the fibers, but also to obtain paper that is perfectly homogeneous, more homogeneous and more resistant than that obtained by previously known methods.
  • the fibrous material can consist of paper pulp and / or glass fibers and / or synthetic fibers and / or textile fibers.
  • the process described in the present invention is more particularly suitable for the production of papers whatever the starting paper pulp: mechanical pulp, semi-chemical pulp, chemical pulp, unbleached chemical pulp, bleached chemical pulp, soda pulp, sulphate paste, kraft paste, bisulfite paste, rag paste, macerated straw paste, leached straw paste, etc.
  • the polyelectrolyte used is a high molecular weight polyelectrolyte, greater than 15,000, with a strong positive potential.
  • the latex used is 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 75%, its viscosity (Brookfield) is between 30 and 650 centipoises at 25 °, and the amount of latex is between 3 and 75% (in dry product) relative to the total dry weight of fibrous materials).
  • the diameter of the divided latex particles is between 0.01 and 0.5 ⁇ . and preferably between 0.1 and 0.2u ..
  • 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 total dry weight 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 sulfate.
  • the solution of phenolic resin has a content of approximately 50 to 85% in solid matter, a viscosity (Brookfield) of between 5,500 and 7,000 centipoise, and the amount added to the mixture (in dry product) is between 0.01 and 50% relative to the total dry weight of the fibrous materials.
  • the fibrous material also contains in its mass, dyes and pigments and / or fungicides and / or insecticides and / or flame retardants and / or bonding agents and / or an inert mineral filler.
  • the fibrous material used is a fibrous material based on pulp recycled from waste paper
  • the added latex consists of a mixture of ethylacrylate and acrylonitrile copolymers and its proportion relative to the dry weight of the materials fibrous is between 40 and 55%.
  • the layer of non-stick material is formed by an aqueous suspension of carboxymethylcellulose with a content of between 0.01 and 10% and brought for 5 to 25 minutes at 90-95 ° C.
  • the suspension of carboxymethylcellulose additionally contains from 0.01% to 85% of polyester and / or from 0.01% to 85% of polyester and / or 0.01% to 75% of a silicone emulsion with anionic or nonionic potential stabilized in an aqueous medium at a pH between 5 and 6.
  • the present invention also relates to sheets of fibrous materials obtainable according to the process according to the invention.
  • the internal cohesion of this sheet is ensured by very fine and homogeneous crosslinking of the latex particles on the fibers which constitutes an intimate graft between the fibers and the latex particles produced by means of the polyelectrolyte.
  • the paper thus obtained and which can be used for many industrial uses has excellent mechanical characteristics which classify it among the best, thanks in particular to its breaking length, to its burst strength, to its breaking strength by tensile strength, its suitability 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 the fibrous materials obtained in accordance with the process described.
  • One of the advantages and not least of the process according to the present invention lies in the possibility of relatively easily recycling any fibrous material obtained according to the present invention, and this unlike all papers containing latex and prepared according to the processes 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 the volume of water and 0.2 to 1.5% relative to the weight of dry fibrous materials) of chloride ions and / or sulfate ions and / or sulfamate 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. In addition to the foregoing arrangements, the invention also comprises other arrangements which will emerge from the description which follows.
  • the present invention relates in particular to the process and the installations for manufacturing sheets of fibrous materials (and in particular paper) containing, in their mass, latex or the like and / or phenoplasts or aminoplasts and the sheets of fibrous materials thus obtained, thus that the means specific to the implementation of these methods, as well as the overall methods and the production lines in which the methods and the installations in accordance with the present invention are included.
  • the fibrous material from a pulp factory is introduced into the tank 1 in the presence of water and coloring matter if necessary, and undergoes appropriate stirring therein allowing the fibrous particles to be suspended.
  • the solids content of the mixture is adjusted to about 2.5%.
  • the prepared fibrous suspension is conveyed to the storage tank 2, then to section 3, known as refining and hydration of the fiber, so that the fibrous material undergoes the structural modifications necessary for subsequent sheet forming.
  • the structural modification must give the mixture a drip index 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 sheet is then re-dried simultaneously, on each side, in section 22. If this optional treatment in section 16 is not used, the sheet passes directly from the section 15 in section 22.
  • the sheet can be engaged in section 23, with a view to imparting it with additional or particular properties by a thickness calibration treatment, embossing or frosting.
  • the sheet can also be engaged in section 24 where it undergoes radiation at high temperature making it possible to ensure, if necessary, complete polymerization of the materials composing it.
  • the treatments in sections 23 and / or 24 are optional, but these additional operations can bring 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 on a reel.
  • Example 2 Preparation of a backing paper for abrasives
  • This sheet of paper is prepared continuously, as described in Example 1, however without passing through section 16, but with passage through section 23 for calibration, then directly to section 25.

  • This paper is prepared according to the process described in Example 1, with the passage in the following sections: Section 15 ⁇ Section 22 ⁇ Section 25.
  • Example 7 Preparation of a paper intended for the manufacture of tear-resistant envelopes
  • This paper is prepared as described in Example 6.
  • an aqueous solution is prepared containing approximately 20% (expressed as dry matter) of polyester emulsion previously stabilized 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 started, and agitated until about 80% of the paper is disintegrated. This disintegration is verified by the usual control procedures in stationery. At this stage, there are still some very fine agglomerates known in stationery jargon as “buttons” or “pastilles”. n then passes the mixture thus obtained through a disintegration device 105, called a "defiler” (for example, defasterer of the "Hydraflaker” brand produced by BLACK CLAWSON), by recycling the juice via the piping 105 to the tank 101 .
  • a disintegration device 105 called a "defiler” (for example, defasterer of the "Hydraflaker” brand produced by BLACK CLAWSON), by recycling the juice via the piping 105 to the tank 101 .
  • the repulpability time in the tank 101 was 25 minutes, the re-tacking time 15 minutes, or a total of 40 minutes to make the 500 kg of fibrous material reusable, directed towards reuse by the piping 104.

  • the raw material thus recovered is reused in a conventional printing-writing support manufacture at a rate of 10% of dry product relative to the total dry weight of the support produced.
  • Table 1 summarizes the mechanical characteristics and Table II represents the characteristics of a paper in which a fibrous material based on recycled pulp was used:
  • the papers obtained according to the process according to the present invention not only have excellent physical resistance, but their suitability for printing coated sheets is quite good, both in exposure and in ink, clarity and color rendering .
