Definitions
- This invention relates to fire resistant products and more especially to fire resistant products produced from expanded polymeric foam materials.
- Expanded polyurethane rigid foams are presently employed for insulation purposes and are produced by mixing together measured quantities of diphenylmethane di- isocyanate and resin in liquid form and then pouring the mixed liquids into a mould or other confined space in which they expand and solidify completely to fill the mould or space.
- the solidified rigid foam is used inter alia to provide enhanced thermal insulation or water proofing properties.
- the present invention sets out to provide an expanded polymeric foam material which is itself resistant to heat and fire.
- an expanded polymeric foam material which comprises a mix of a foam forming agent, a resin, fibrous material and an exfoliating material.
- the foam-forming agent may comprise an organic isocyanate, more especially diphenylmethane di-isocyanate.
- the exfoliating material may comprise powdered exfoliating graphite and/or powdered sodium silicate.
- the fibrous material may comprise man- made mineral fibres (M F) and/or inorganic fibres.
- the inorganic fibres may comprise ceramic fibres such as alumina silicate fibre and the man-made mineral fibre may comprise rockwool fibre or glass fibre.
- a method of producing an expandable polymeric foam material which comprises the steps of mixing together a foam forming reagent, a quantity of fibrous material and resin and adding to the liquid mix a quantity of powdered exfoliating agent.
- the resulting mix may be poured into a mould, confined space or the like or applied to the surface of a wall, ceiling, panel, tile or the like before the foam rises and solidifies.
- the invention provides for mixing together to form a polymeric foam material, discrete quantities of a foam forming reagent, a resin and powdered exfoliating material and a fibrous material.
- a fire resistant polymeric foam material in accordance with the invention is given by way of example only.
- the material in question is a fire resistant expanded polyurethane foam material.
- a foam-forming reagent which has at 20°C a viscosity of 350 mPa.s and a specific of gravity of 1.24.
- the mix rate of foam forming reagent (FFR) to liquid resin is 50% FFR to 50% resin by weight.
- the free core density of the rigid foam is typically between 30 and 35 Kg 3 and the cream and rise times of the foam are typically between 40 and 50 seconds and between 180 and 220 seconds respectively.
- the resin has at 20 ⁇ C a viscosity of 295 mPa.s and a specific gravity of 1.20.
- the resin is preferably a fully formulated liquid mixture and may comprise a resin such as used by the company Baxenden Chemicals Limited in their ISOFOAM RM118 rigid foam system.
- the FFR is preferably diphenylmethane di-isocyanate which may comprise a crude MDI such as used by the company Baxenden Chemicals Limited in their ISOFOAM RM118 rigid foam system.
- the amount of exfoliating agent and/or man-made mineral fibres added to the liquid FFR and resin will depend upon the degree of fire proofing required.
- the content of these materials may, in total, represent between 1% and 90% of the mix of the materials of and the liquid FFR and resin.
- these additions will be between 5% and 80% by weight. Preferred ranges of such additions are 10% and 60% and 15% and 40%.
- a typical addition is 25% .
- Rigid foams produced in accordance with the invention have many applications these including inter alia filling spaces between for example cable conduits and an adjoining wall surface or internal walls of a house, and as a coating for wall and ceiling panels.
- the sodium silicate content of the rigid foam prevents burning through of the rigid foam and the exfoliating content causes the foam to expand to present a barrier to the fire and to prevent its spread to other areas.

Abstract
On décrit un matériau en mousse de polymère expansée comprenant un mélange d'agent de formation de mousse, une résine, un matériau fibreux et un matériau exfoliant. L'agent de formation de mousse peut comprendre un isocyanate organique, plus précisément un di-isocyanate diphénylméthane. Le matériau exfoliant peut comprendre du graphite exfoliant en poudre et/ou du silicate de sodium en poudre. Le matériau fibreux peut comprendre des fibres minérales synthétiques et/ou des fibres inorganiques.
