Abstract

The material comprises a layer of flame-proofed, fibre felt faced on one side thereof with a flexible, gas- impermeable covering e.g. a metallic foil, such as aluminium foil, or of a thermoplastics film, which may itself be metallised or carry a metallic foil on the face remote from the felt. The effect of the coating is to render the felt impermeable to gases i.e. combustion products, and, in the case where the cooling comprises the thermoplastics film, to act as a binder at temperatures to which the material is submitted in use. The material is especially useful for extinguishing chip-pan fires.

Description

SPECIFICATION Fire Blanket Material The present invention relates to a material for use as a fire blanket.
One of the most serious domestic fire hazards is a burning chip pan. The reason for this is that the combustion of the fat gives rise to a temperature of the fat vapours in the pan which is considerably in excess of the flashpoint of those vapours. This means that after the flames have been extinguished, combustion air must be kept from the fat vapours for a considerable time thereafter in order to avoid spontaneous reignition of the fat vapours. A further difficulty is that the temperature of combustion is so high and the pan itself becomes so hot that only a limited number of materials can be used for the purpose of providing a fire blanket to smother the fire. A particular difficulty is that the rim of the pan becomes so hot that it is capable of burning its way through a material that would otherwise be capable of containing and smothering the fire.
Various materials have been used to provide a fire blanket, but none is entirely satisfactory on the ground of cost and/or effectiveness or even for other reasons. For instance, asbestos has been used, but it is no longer acceptable on medical grounds since it is thought to be dangerous to the lungs. A material should, therefore, be effective and cheap enough to avoid dissuading a householder from buying a blanket made of the material on the ground of cost, and should be otherwise acceptable.
It is an object of the present invention to provide such a material.
In an embodiment of the present invention, there is provided a material suitable for use as a fire blanket, the material comprising a viscose and wool pressed felt flame or fire-proofed, for instance, in a conventional manner with e.g.
ammonium bromide or ammonium phosphate, and being faced on one side with a film of polyester. The thickness of the layer of felt employed may be as little as 1 millimetre; and preferably the polyester film is one which has been metallised with, for instance, aluminium.
The felt alone is ineffective for extinguishing a chip pan fire since the hot rim of the pan quickly burns through the felt and thus permits air to be admitted to the interior of the pan to cause reignition of the fat vapours. Likewise, the polyester film whether metallised or not is also ineffective. The material of the embodiment, however, is consistently effective in extinguishing a chip pan fire. It is immaterial which side of a blanket made of the material of the embodiment is placed first down in the pan vis:- the material is still effective regardless of whether it is the felt side or the polyester film side which is laid first down on the pan.
In view of the fact that neither the felt not the polyester film alone is in any way effective for extinguishing a chip pan fire, the effect produced by the material of the embodiment is extremely surprising.
While the applicants do not wish to be bound by any theory as to the effect of the material of the embodiment, it is observed that an effect of the polyester film is to render the felt impermeable to the passage of gases; and the applicants believe that it is because of this that the material of the embodiment is effective. This conclusion is supported by the fact that if the polyester film is replaced with a polymeric film having similar properties e.g. PVC film, or with a material such as metal foil, e.g. aluminium foil, the material is still effective. Thus, if the felt is faced with a layer of aluminium foil, the material produced is again consistently effective to extinguish a chip pan fire. It has also been ascertained that a metallised polyester film is more effective than a polyester film per se.Thus, afpolyester film metallised with aluminium is somewhat more effective than the polyester film itself. No explanation can be offered at the present of this fact.
Whilst the effectiveness of the material of the embodiment appears, therefore, to be due to the fact that the felt is rendered impermeable to gases, this is only so provided the felt has been fire-proofed. The viscose also has an effect.
Flame-proofing is known to contribute to the heat resistance of the material, but the presence of viscose would be thought considerably to reduce the effectiveness of the material to resist heat.
However, it has been observed that the viscose is charred especially by contact with the rim of the chip pan and it appears that on charring it tends to form a residue which stiffens the remainder of the material and thus helps to keep the felt intact.
It may also be that the charred viscose in contact with the rim of the pan provides a heat barrier which serves to insulate the material above it from the rim of the pan.
In view of this, other fibres which charr under heat e.g. aromatic polyamides such as those sold under the registered Trade Mark "Nomex" and "Novlar" may be used wholly or partly to replace the viscose. It will be understood in this connection that the charring of the fibres takes place in the presence of the flame-proofing agent.
It is also observed that a polymeric film such as a polyester or polyvinyl chloride has the property of melting under the influence of heat and that when used together with the felt and melted under the influence of the heat from the chip pan, it tends to become impregnated in the fibres of felt and thus bind them together; and this may also have an effect in helping to maintain the structural integrity of the felt. It appears, therefore, that the polymeric film should consist of a thermoplastic material or at least of a polymeric material which will melt under the influence of heat.
The pressed felt employed in the present invention need only have a density of 0.2 g per cc and be some 1 millimetre thick. It is therefore, a very economical material particularly since it may employ viscose in the viscose wool mixture in an amount of up to 70 percent of the total weight of wool and viscose or fibre used in place thereof. If the felt is a needle felt, it need not employ wool.
The covering on the felt may itself, on the side thereof remote from the felt, be covered with a layer of felt.
In producing a material of the present invention, the polymer film or other covering is adhered to the felt by any suitable noninflammable adhesive; the adhesive being applied to the respective side of the felt and the covering being pressed onto the adhesive side of the felt by rolling the felt and the covering together.
In a further aspect of the invention, the amount of flame proofing agent employed is substantially greater than the quantity normally used for the purpose of flame proofing.
