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.
  • French Patent No. 2,461,061 of the applicant describes products obtained by forming a sheet on a papermaking machine fourdrinier wire or cylinder mold from an aqueous composition by removing water from the thus formed sheet on the canvas and drying it.
  • the aqueous composition comprises: - cellulosic fibers, - non-cellulosic fibers, - at least one thermoplastic powder, - at least one binder, - possibly charges.
  • the flocculant is for example a cationic agent which confers positive charges on the cellulosic fiber.
  • the flocculant is added in two stages and provides improved retention of thermoplastic powders and fillers.
  • French Patent No. 82 12319 of the applicant describes a paper sheet which improves the dimensional stability by adjusting the amount 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 material thermoplastic to obtain a covering, 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 invention aims to solve these problems.
  • the object of the invention is therefore to obtain a sheet by the papermaking route, usable as a covering support for manufacturing floor or wall coverings and which has the following physical properties: - a satisfactory RTD, preferably greater than 300 N / m, more preferably 500 N / m and beyond, - a sufficient thickness, greater than 350 micrometers and preferably greater than 450 micrometers and even 500 micrometers, - a strong hand, - dimensional stability at high humidity.
  • 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 route, comprising cellulosic fibers, non-cellulosic fibers, at least one flocculant, at least one thermoplastic powder, at least one binder, optionally fillers and additives.
  • thermoplastic powders whose average particle size is between 25 and 60 micrometers are used.
  • 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 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 two jaws are placed inside the heating box, the temperature is raised to the chosen value (200 ° C), the paper test piece (140 mm x 15 mm) is quickly inserted (5 seconds) between the two jaws separated by 100 mm, the sample is left for 2 minutes at temperature, before breaking according to the standard ISO 1924/1976. Finally, we average five measurements.
  • the tensile-delamination resistance is measured as follows:
  • the PVC-coated sample is kept on both sides in a ventilated oven.
  • the treatment time is adjusted to 200 ° C to obtain a regular foam formation, approximately 2 min. - Cool 5 min. - Two strips 50 cm wide and 20 to 25 cm long are cut.

  • 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 particle 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.
