Definitions

  • the invention relates to a sheet prepared by papermaking and usable as a substitute for products known under the name of impregnated glass veils.
  • the flocculant is for example a cationic agent which confers positive charges on the cellulosic fiber.
  • the flocculating agent is added in two stages and allows improved retention of the thermoplastic powders and fillers.
  • Patent application EP-A-0 039 292 of the applicant describes a sheet material obtained on a paper machine, from an aqueous composition comprising reinforcing fibers which are not cellulosic, a thermoplastic resin powder, a polyolefin paste, a binder and at least one flocculating agent.
  • This material is intended to be used in hot forming processes, involving a fusion of the thermoplastic powder and the polyolefin paste. This material is hot-consolidated; before the thermoplastic powder and the polyolefin paste melt, these mechanical characteristics are insufficient for it to be used as it is and in particular as a coating support.
  • Patent application FR-A-2 530 274 by the applicant describes a paper sheet, the dimensional stability of which is improved by adjusting the quantity of glass fibers.
  • the layer is then heat treated to cause partial gelation of the thermoplastic powders.
  • the user of such a paper sheet thus impregnated, deposits the various compositions of thermoplastic material to obtain a coating, for example a floor covering or wall covering.
  • Such paper sheets must have excellent physical characteristics.
  • the sheets must withstand passage through industrial ovens up to high temperatures, in particular during the manufacture of these floor or wall coverings.
  • the support paper sheets must therefore be heat resistant.
  • the level necessary to obtain a stable product after laying depends on the thickness and / or grammage of the sheet.
  • an elongation of 0.25% in the cross direction seems to be a limit not to be exceeded.
  • the Applicant has found that the particle size of the thermoplastic powder has an influence on the R.T.D. and that by using powders with a large particle size compared to the powders usually used in stationery (maximum particle size: 5 micrometers), the R.T.D. while increasing the thickness of the sheet.
  • the invention therefore relates to a new sheet prepared by the papermaking process, having a tensile-delamination resistance. greater than 300 N / m, usable as a coating support, comprising cellulose fibers, non-cellulose fibers, at least one flocculant, at least one thermoplastic powder, at least one binder, optionally fillers and additives, said sheet optionally coated on at least one side with an impregnation layer comprising at least one plasticizer of the thermoplastic powder.
  • thermoplastic powders are used whose average particle size is between 25 and 60 micrometers.
  • P.V.C. powders obtained by suspension polymerization can be used, the average particle size of which is between 25 and 60 micrometers. More preferably, it is possible to use P.V.C. powders obtained by suspension polymerization, the average particle size of which is between 25 and 50 micrometers.
  • the laboratory tests E 14.12.87 and E 15.12.87 and the industrial test E 2137 correspond to the first mass composition.
  • the coating sauce the composition of which is given in Table I, is applied to only one side of the sheet.
  • the industrial test E 2145 corresponds to the second mass composition.
  • the coating sauce the composition of which is given in Table I, is applied to both sides of the sheet.
  • the hot tensile strength is measured as follows: an Adamel-Lhomargy DY 22 device is used, with a 10 daN load cell, a recorder and an Adamel-Lhomargy CE 02 heating chamber.
  • the tensile-delamination resistance is measured as follows:
  • Table I therefore shows that it is possible to produce a sheet by the papermaking route, usable as a coating support and having all the physical properties targeted by the invention.
  • the basic composition of the sheet and the composition of the coating sauce are those of test E 15.12.87.
  • the coating sauce is applied to both sides of the sheet.
  • the removal is 70 g / m2.
  • Figure 1 shows the evolution of the hand and the R.T.D. depending on the grain size.
  • thermoplastic powder is imposed by the powdering of the sheet. Such dusting would cause fouling of the paper machine and also of the material during the operations of coating the thermoplastic layers at the transformers.
  • the Applicant has observed dusting for an average particle size greater than 60 micrometers.
  • the average particle size of the thermoplastic powder must therefore be between 25 and 60 micrometers and preferably between 25 and 50 micrometers.
  • Table II shows the particle size of the powders according to the polymerization method.
  • thermoplastic powder should not be limited to the PVC homopolymer. Indeed, it is obvious that any polymer developing, after melting, plasticization or gelation, a high binding power may be suitable, in particular vinyl chloride / vinyl acetate; vinyl chloride / vinyl acetate / ethylene terpolymers.
  • plasticized P.V.C. powders can come from recycled P.V.C. obtained by grinding already plasticized P.V.C., which was in the form of films, sheets or tubes manufactured according to different processing techniques.
  • These pre-laminated P.V.C. powders can also come from mixtures called “wetblends” or “dryblends”.
  • Di (2-ethylhexyl) phthalate can be used as plasticizer and also dibutyl phthalate, benzyl butyl phthalate, dihexyl phthalate, diisononyl phthalate, tricresylphosphate or any other plasticizer, usually for the transformation of poly (vinyl chloride).
  • composition of the mass is as follows (the quantities are expressed by weight of dry products):
  • composition of the coating sauce applied to the sheet in size-press is as follows (the quantities are expressed by weight of dry products):
  • any cellulosic fiber or mixtures of these fibers can be used.
  • Non-cellulosic fibers are mineral or organic fibers.
  • cut glass fibers with a diameter between 7 and 12 micrometers and a length between 3 and 6 mm.
  • the flocculants which can be used are for example the following: Aluminum sulphate Aluminum polychloride (aluminum hydroxychloride) Sodium and calcium aluminate Mixture of polyacrylic acid and polyacrylamide Polyethyleneimine Copolymer of acrylamide and ⁇ -methacrylyloxyethyltrimethylammonium methyl sulfate Polyamine-epichlorohydrin and diamine-propylmethylamine resin Polyamine-epichlorohydrin resin Polyamide-polyamine-epichlorohydrin resin Cationic polyamide-polyamine resin Condensation products of aromatic sulfonic acids with formaldehyde Sodium pretreated epoxy polyamino amide Aluminum acetate Aluminum form Mixture of aluminum acetate, sulfate and formate Aluminum chloride (AlCl3) Cationic starch

  • Kaolin Aluminum silicate hydrate complex - particles from 1 to 50 micrometers, preferably 2 to 50 micrometers - specific weight 2.58.

  • Natural barium sulphate particles from 2 to 50 micrometers specific gravity about 4.4 - 4.5.
  • Precipitated barium sulphate particles 2 to 20 micrometers specific gravity about 4.35.
  • Diatomic silica particles from 2 to 50 micrometers - specific gravity about 2 to 2.3. Satin white: calcium sulfoaluminate hydrates.

  • Magnesium hydroxide particles from 2 to 50 micrometers.
  • Alumina hydroxide particles from 2 to 50 micrometers. Note : the specific weight is expressed in g / ml.
  • calcium carbonate will be used which gives the sheet better heat resistance.
  • the adjuvants known in the paper industry such as anti-foaming agents, agents for dry resistance, wet resistance, rot-proofing, antioxidants, dyes, flame retardants, etc.
  • Polyvinyl chloride thermal stabilizers commonly used and which are miscible in plasticizers or water are suitable; preferably used barium and zinc salts.
  • the level of flocculants will be adapted by a person skilled in the art; it depends on the quantity of materials introduced and in particular on the level of binder.
  • the percentage of the second flocculant is given relative to the dry weight of the mass arriving in the headbox. The total of the above percentages, except the percentage of the second flocculant, must be equal to 100.
