Abstract

A polymeric or resin-based foam material incorporating a fire- extinguishing material, the latter being an alkali metal halide or di-ammonium phosphate, or a mixture of both, dispersed within the foam material.

Description

SPECIFICATION Fire resistant foam composition The invention relates to a fire resistant foam composition and is particularly, but not exclusively, concerned with a polymeric or other resin-based foam material.
Polymeric foam materials, for example polyurethane foam, are widely used as upholstery for furniture and in many other applications. They are inflammable, however, and have contributed to serious fires and moreover when burning release toxic gases.
An object of the invention is to render such foam materials fire-resistant or less flammable.
According to the invention, a polymeric or resinbased foam material incorporates a fireextinguishing material, the latter being an alkali metal halide or an ammonium phosphate, or a mixture of both, dispersed within the foam material, the proportion of fire-extinguishing material relative to the foam material, but disregarding any other additives which are mixed with the reactants constituting the foam material either during or after its preparation, being between 10 and 100 parts by weight of said fire-extinguishing material to 100 parts of said foam material.
Preferably the alkali metal halide is sodium chloride and the ammonium phosphate is di-ammonium phosphate (NH4)2 HPO4.
The preferred fire-extinguishing material may therefore be sodium chloride or di-ammonium phosphate either alone, or together in any quantity within the aforesaid range of between 10 and 100 parts by weight to 100 parts by weight of said foam material, Where sodium chloride and di-ammonium phosphate are used together a mixture of any desired proportions by weight of between 20 parts of one and 80 parts of the other in 100 parts of the mixed fire-extinguishing material are used.
The foam material or the fire-extinguishing material may include a colouring agent to indicate that the foam material has fire-resistant properties.
The foam material may be of any polymeric or resin-based kind.
For example it may be polyurethane and be made in an known manner by reaction between a triol and di-isocyanate together with any catalyst or other additive.
The fire-extinguishing material provided by this invention may be added before or after the mixing of the triol and the di-isocyanate or other reactants.
Any bulk material may additionally be added before or after or with the fire-extinguishing material. For example, glass fibre may be added to the fire-extinguishing material orthefoam material or its constituents.
The fire-extinguishing material may be added as a powder or in a slurry to a constituent of the foam material before the preparation of the foam material or to the mixed constituents during the preparation of the foam material. Alternatively the additive or mixed additives may be added to the foam material after it has been produced, For example the additive or mixed additives may be added to the foam material in a solution or slurry by saturating the foam material with the solution or slurry by pouring the solution or slurry on to the foam material; by immersing the foam material in the solution or slurry, or by spraying the foam material with the solution.
The additives or mixed additives, as aforesaid, are in this example sodium chloride or di-ammonium phosphate either alone, or together in any quantity within the range of between 10 and 100 parts by weight to 100 parts by weight of the foam material or its constituents. Where the sodium and diammonium phosphate are used together the mixture is in any desired proportions by weight of between 20 parts of one and 80 parts of the other in every 100 parts of the mixed fire-extinguishing material.
The foam material provided by this invention has good fire-resistant properties and is not difficult to make as both sodium chloride and di-ammonium phosphate are readily available.
