Definitions

  • the invention relates to a flame-retardant, flexible polyurethane flexible foam which is produced from a foam reaction mixture which comprises a polyol mixture, polyisocyanate, expandable graphite as flame retardant and additives.
  • Such a flexible polyurethane foam is known from DE 39 09 017 C1 of the Applicant.
  • a polyol mixture consisting of polyether polyol and polymer-filled polyol is used.
  • the flame retardant used is expanded graphite in platelet form, in which the platelets have the same order of magnitude as the resulting foam cell walls and are first mixed into the reaction component polyol.
  • Such flame-retardant polyurethane flexible foams are used in particular as seat cushions for aircraft or rail vehicles.
  • the foam In addition to high demands on the fire behavior, the foam must also have high long-term use properties. To meet these requirements, the known foam has a relatively high density, which leads to an increased energy consumption.
  • the present invention seeks to propose a flame-retardant, flexible polyurethane flexible foam, which has a reduced weight while maintaining or increasing the life.
  • a flexible polyurethane foam of the type mentioned that the polyol mixture has 50% to 90% by weight based on ethylene oxide based polyol (EO polyol) and 50% to 10% of standard polyol and / or filler polyol ,
  • the flexible polyurethane foam according to the invention has very good long-term use properties at low density. Compared with conventional flexible polyurethane foams, the weight can be reduced by about 30%. This is particularly advantageous when using the flexible polyurethane foam as a seat cushion for aircraft, as this can be the aircraft weight and thus the fuel consumption can be reduced.
  • the weight fraction of the ethylene oxide-based polyol is 80% and the weight fraction of the standard polyol and / or filler polyol is 20%.
  • the polyisocyanate portion is used with an amount of isocyanate corresponding to a ratio of 90 to 105.
  • a diisocyanate is used.
  • the proportion of expandable graphite is 50 to 40 parts by weight, in particular 30 parts by weight, based on 100 parts by weight of polyol.
  • the expandable graphite flame retardant is advantageously present with a grain size of 0.2 to 1 mm.
  • the expandable graphite flame retardant is in platelet form.
  • the additives contain in particular water, a catalyst and a stabilizer.
  • the foam reaction mixture has:
  • the density of the flexible polyurethane foam is advantageousously, the density of the flexible polyurethane foam
  • Table I shows a comparison between the novel flexible polyurethane foam according to the invention and a comparison foam according to the prior art.
  • Polyol 2 EO polyol e.g. Bayfit 41WB01
  • Stabilizer 1 Tegostab 4900 (Evonik)
  • the polyurethane flexible foam according to the invention has the composition shown in the left-hand column. It can be seen that the polyol mixture consists of a standard polyol (polyol 1) and an ethylene oxide based polyol (polyol 2). In contrast, in the comparative foam is a polyol mixture consisting of a standard polyol (polyol 1) and another standard polyol (polyol 3) is used, as can be seen from the right column of Table I. The catalysts and stabilizers used are the same for both foams.
  • a diisocyanate is used with an amount of isocyanate corresponding to a ratio of 90 to 105.
  • Table II shows the physical properties of the new foam and two comparative foams of different density.

  • the physical values such as compression set according to DIN EN ISO 1856, wet compression set according to DIN EN ISO 1856 and fatigue test according to DIN EN ISO 3385 are shown in column 1. As can be seen from the comparison with column 2, the known comparative foam with an identical density of 40 kg / m 3 has much poorer physical properties.
  • the comparative foam must have a density of 65 kg / m 3 , as shown in column 3.
  • the polyurethane flexible foam of the invention has the same physical properties by about 30% reduced weight.
  • the reduced volume weight results in particular when using the foam as upholstery for aircraft and rail vehicles advantages because the energy consumption can be reduced.
  • the foam according to the invention can also be used for mattresses which are used in security areas such as prisons.
  • the foam is produced by the process described in DE 39 09 017 C1.

Abstract

L’invention concerne une mousse souple de polyuréthanne élastique et ignifuge, qui est fabriquée à partir d’un mélange réactionnel de mousse qui comporte un mélange polyol, un polyisocyanate, un graphite expansé en tant qu’agent ignifuge et des additifs. Afin de réduire la densité en conservant les propriétés de durée d’utilisation, le mélange polyol comporte 50 à 90 parties en poids de polyol à base d'oxyde d'éthylène et 50 à 10 parties en poids de polyol standard et/ou de polyol-charge.
