Definitions

  • the invention pertains to the technical field of fire retardant compositions for use in wood composite panels.
  • Wood composite panels are widely used in the construction business. Both wood as well as these wood-base materials have to meet extensive requirements with regard to flameproof properties. In Europe, various standards and requirements are introduced which allow comparison of fire properties of construction materials (e.g. Euroclasse EN 13501-1). Characteristics such as hardly inflammability, ignitability, flame spread, calorific value as well as the development of smoke and burning droplets of the material are all taken into account when classifying a construction material in these classes. In order to meet these requirements and to meet the highest quality standards, wood composite panels are during their production often supplemented with compositions with fire retarding characteristics and optionally smoke suppressors.
  • US 8 715 540 for instance describes a fire retardant composition for reducing the amount of burning that occurs to a material as well as the smoke density which is produced.
  • the composition may be added to construction material.
  • EP 2 586 849 is directed to an aqueous composition comprising monoammonium dihydrogen phosphate as flame retardant.
  • the composition is used during the production of wood composite panels to create flame retarding wood composite panels.
  • WO 02/102926 describes a fire retardant composition consisting essentially of tributylamine, borax and monoammonium phosphate, which in aqueous solution has a resulting pH of 6.0 to 8.5 and which is used in the production of fiberboards by spraying.
  • US 4 725 382 concerns a water soluble fire retardant composition that utilizes pH control to afford a fire retardant material of low corrosiveness and comprises boric acid, monoammonium phosphate and diammonium phosphate. pH of an aqueous solution is about 6.7 to 6.95.
  • the production of these wood composite panels typically makes use of an adhesive or resin to provide cohesion to the wood particles or fibers. Addition of additives such as fire retardant compositions can have an impact on the functionality of these resins (e.g. lower bond strength). As a consequence, higher amounts of resins are sometimes needed in order to ensure good cohesion of the articles and thus good quality end products.
  • the current invention aims to provide a solution for the latter by fine-tuning the fire retardant composition in function of the chosen resin.
  • the present invention provides for a fire retardant composition according to claim 1.
  • This composition is particularly useful for use in wood composite panels.
  • the pH of the composition has been meticulously adapted by the addition of one or more pH regulators, in order to provide a good compatibility with the resins used during the production of the wood composite materials.
  • the pH may be further controlled, based on the specific resin used during the production.
  • the present invention provides for a fire retardant composition according to claim 2.
  • This composition is particularly useful for use in wood composite panels and comprises an intumescent formulation. While intumescents are known to be used as fire retardant, their use in wood composite panels has to date been limited to coatings of the finished panels, because of their incapability with the resins used for the production of the panels. These panels are typically produced of cellulose containing material such as wood chips, which are bound together by a resin and pressed. Previously, when adding the intumescent formulation to the cellulose containing material and resin, the formulation and resin were found to react. This led to an early activation of the intumescent formulation as well as degradation of the resin.
  • the inventors of the current invention now found that by adapting the pH of the composition by the addition of one or more pH regulators, the intumescent formulation could also be applied in the core of a wood composite panel.
  • the pH of the fire retardant composition By controlling the pH of the fire retardant composition to a very specific and predetermined range, the inventors of the current invention found that the unwanted activation of the intumescent formulation and degradation of the resin was prevented.
  • the intumescent formulation and resin remained stable during the production of said wood composite panels. This allows for a use of the composition within the panel rather than as a subsequent coating once the panel has been produced. As a consequence, the production of the panels is more efficient and cost effective.
  • the present invention provides for a specific use of the composition in fire retardant wood composite panels according to claim 22, the respective method for producing those panels in claim 23, as well as the resulting panels according to claim 24.
  • the resulting panels comply with various fire test standards (ASTM, EN, DIN, BS, NF P) for construction products.
