Definitions

  • the present invention relates to the field of substitutes for impregnated glass veils.
  • the invention relates to sheet products obtained by the papermaking process, with a high content of latex precipitated in the mass.
  • the product obtained also has a good foldability.
  • These products do not contain fillers, but can contain up to 2/3 by weight of latex.
  • Tables I and II below provide a comparison of formulations typical of the abovementioned patent applications and of the same formulations to which attempts have been made to add charges.
  • Table I collects the formulations and Table II collects the results.
  • document FR-A-2458623 discloses a composition with a low level of latex intended for the manufacture of mineral felts: these felts are characterized by poor resistance to delamination and poor dimensional stability.
  • the object of the invention is to provide a composition of fibers, fillers and latex which makes it possible to obtain products containing a high percentage of fillers (therefore very economical) and which however, which is surprising, has resistance to delamination. at least equal to that of previous products.
  • the non-cellulosic fibers will preferably be glass fibers, or else also other mineral or synthetic fibers such as rock wool, polyester fibers and similar fibers. Their main role is to provide dimensional stability to the support with respect to water and to temperature variations, these two properties being essential for the applications envisaged.
  • cellulosic fibers which are weakly refined, in particular between 15 and 35 ° S.R.
  • Cellulosic fibers refined at 20 ° S.R. and glass fibers about 3 or 4 mm long and 10-11 wm in diameter were used in the tests.
  • glass fibers of length between 3 and 12 mm, preferably 3 and 6 mm, and of diameter between 5 and 15 l im.
  • a ratio of 40 to 60 parts by dry weight approximately of mineral fibers is preferably chosen for 100 parts of cellulose fibers, especially when these mineral fibers are glass fibers whose length is between 4 and 6 mm.
  • a ratio of 40 to 60 parts by dry weight approximately of mineral fibers per 100 parts of cellulose fibers will preferably be chosen.
  • reinforcing fibers to increase the wet mechanical strength.
  • polyvinyl alcohol fibers or polyolefins in proportions known to those skilled in the art and corresponding to the desired objective.
  • the amount of latex to be introduced in bulk is dependent on the nature of the filler used in the formulation.
  • the nature of the flocculants, their dose, as well as the number and place of introduction may vary depending on the nature of the latex used, the material, the contact time between the products; the total dose of flocculants, which itself depends on the nature of these flocculants (in particular molecular weight, ionicity, etc.), will preferably be between 2 and 20 parts by dry weight, per 100 parts by dry latex weight.
  • compositions used as well as the results of the tests are collated in Tables IV to XV below; these examples are of course not limiting.
  • the alumina hydroxide which gives satisfactory results will be suitable for the manufacture of flame retardant supports.
  • Such a treatment therefore makes it possible, for comparable dimensional stability, to substantially reduce the proportion of glass fibers in the support.
  • tests MP 19474 and 19487 show the loss of dimensional stability when the amount of latex goes from 42.5 parts by weight (MP 19474) to 37 parts by weight (MP 19487) per 100 parts by weight of mixture of based.
  • stage 2 To combat the rolling of plastisol coated products on one side on the front, it is preferable to carry out a treatment of stage 2 on the back side.
  • stage 2 treatments can be coating, impregnation, surfacing operations, aiming to deposit chemical components on the surface or at the core (by spraying, size-press, coater with blades or rollers, etc.). Mention will in particular be made of the addition of latex or of plasticizer by size-press.
  • thermal and / or mechanical treatments such as smoothing or calendering cold or hot.
  • the product will generally be deposited at a rate of 10 to 100 g / m 2 (wet state), ie 2 to 40 g / m 2 after drying (preferably 2 to 20 g / m 2 ) in the case of a treatment on one side only, and 3 to 60 g / m 2 in the case of a treatment on both sides.
  • VETROTEX Fibers 4.5 mm long and 10 ⁇ m in diameter supplied by VETROTEX Glass fibers B
  • VETROTEX Fibers with a length of 3 mm and a diameter of 7 ⁇ m.
