The waterproof barrier may be a cellulose varnish, a liquid wax, and oil-bound paint or a silicone coating. The barrier may also be a plastics sheeting or fibre glass layer which may themselves be coated.

Description

FIRE-PROOFING This invention relates to a method of fireproofing at least a surface of an otherwise flammable product, as well as to a product whenever having a fire-proof surface produced by a method of this invention, and to compositions for fire-proofing at least a surface of a product.
In this Specification, the term "fire-proofing" is intended to mean increasing the resistance to fire, rather than making a product strictly non-flammable.
Thus, a product treated by a fire-proofing method of this invention may still be flammable if subjected to a sufficiently high temperature for a sufficiently long time, though the product if left untreated would have been flammable either at a lower temperature, or within a shorter period of exposure to such a temperature, or of course both of these, in combination. The term "fire-proofing" used herein should therefore be understood to have this somewhat narrower meaning commonly used in the art, as distinct from rendering a product wholly non-flammable, irrespective of the temperature to which the product may be subjected and the time of exposure to that temperature.
It is known to treat absorbent materials - such as textiles, paper and so on - with solutions containing sodium silicate, in order to fire-proof (that is, to increase the resistance to fire, as discussed above) that product. It is also known to include in such solutions further compounds in order to enhance the stability and effectiveness of the fire-proofing treatment. Though such treatments undoubtedly are effective, it is a principal aim of the present invention to provide a fire-proofing treatment which enables a product so treated to exhibit a greater resistance to fire than might be expected from conventional silicate treatment processes.
According to one aspect of the present invention, there is provided a method of fire-proofing at least a surface of an otherwise flammable product, comprising the steps of: wetting at least the surface of the product with a silicate solution; allowing or causing the solution to dry to form a silicate coating on the surface of the product; and then applying a waterproof barrier layer to the surface of the product.
As a result of trials and tests, it has been established that the integrity and stability of a silicate coating given to a product by way of the application of a silicate solution is most important in order to give enhanced fire-proofing properties.
Sodium silicate (being a conventional fire-proofing substance) is at least to some extent hygroscopic and if the coated surface of a product is allowed to absorb moisture from the atmosphere, then the integrity of the silicate coating may be impaired. In the present invention, the provision of a waterproof barrier layer over the surface of the product treated with the silicate solution serves to inhibit the absorption of moisture by the silicate coating, and so to maintain the integrity of the silicate coating; in turn, this leads to enhanced fire-proof properties for a product treated by the method of this invention.
The coating on the surface may be formed simply by wetting the surface, and causing or allowing the solution to dry. In the case of an absorbent product, the solution will soak into the product as well as form a coating. Yet another possibility is to incorporate the solution in a manufacturing process for the product so as still to form a coating on a surface of the product. For example, in the case of paper or card manufacture, the solution may be added to the pulp before the pressing thereof, whereby drying of the pulp forms the coated surface of the finished paper or card.
The wetting of the surface of the product to be treated is preferably performed with a solution in water of, or primarily of, sodium silicate. Such a solution may be a saturated solution of sodium silicate, which may be produced for example by dissolving an excess of sodium silicate powder in a commercial grade of sodium silicate solution containing 18% by weight of sodium silicate; the treatment solution may contain from 10 to 80 parts by volume of 18% by weight sodium silicate solution in which there has additionally been dissolved a further 10 to 80 parts of sodium silicate power.
It is also known to use potassium silicate as a fire-proofing composition. The silicate solution used in the process of the present invention may contain potassium silicate, preferably in the range of 10 to 60 parts, by volume.
The silicate solution may additionally contain silica power, further to enhance the fire-proofing properties of the solution. Typically, such silica power may be contained in the range of 10 to 20 parts.
Depending upon the nature of the surface of the product to be treated by the method of the present invention, the silicate solution may also contain other compounds, for example to enhance the adhesion of the coating to the surface, or to enhance the absorption of the silicate solution by the surface. Thus, the solution may further contain one or more of a polyvinyl alcohol adhesive, ammonium sulphate, exfoliated graphite, and sodium methyl silicate. In addition, the solution may contain an emulsifying agent.
The method of this invention as described above may be enhanced by performing additional steps following the drying of the silicate solution wetted on the product surface, which additional steps comprise: wetting again the surface of the product with a silicate solution substantially the same as or similar to that used for the first surface wetting step; applying a sheet of absorbent material to the wetted surface; and allowing or causing the surface to dry, thereby to adhere the absorbent material to said surface.
Following the performance of these additional steps, the waterproof barrier layer should be applied to the surface of the product, over the sheet of absorbent material. The provision of the absorbent material may provide a better key for the waterproof barrier layer, especially for certain types of waterproof barrier layers, and may also serve to assist the maintenance of the integrity of the silicate coating. The absorbent material may comprise a sheet of paper or of paper tissue, a matting or tissue of glass fibres, a textile fabric of natural or synthetic fibres, or a textile fabric of both natural and synthetic fibres.
For many purposes, the waterproof barrier layer may comprise a siccative coating, for example of a varnish or of paint. Tests have shown that cellulose varnishes or paints may be particularly suitable as exhibiting sufficient waterproof properties.
Alternatively, a wax coating may be used as the waterproof barrier layer. Yet another kind of waterproof barrier layer suitable for use in the treatment process of this invention is a plastics material sheet, suitably laid on the surface. For example, a relatively thin film of plastics material having self-adhesive properties, commonly referred to as "cling film", may be employed. Alternatively, a thin layer of plastics may be fused or run on to the surface by the application of heat to the plastics material. A polyethylene sheet may advantageously be used for this purpose.
This invention extends to a product whenever having a fire-proofed surface produced by the use of a method according to this invention. The invention further extends to a silicate coating solution as described above and for use in a fire-proofing method of the invention.
In order that the invention may better be understood, it will now be described in greater detail in certain specific Examples thereof given.
The fire-proofing treatment of the present invention may be applied to a absorbent and nonabsorbent substrates of paper, card, wood, plastics materials such as polystyrene and polyurethane foam, textiles, hessian, and so on, in order to enhance the fire resistant properties of the substrate. The silicate solution may be applied by brush, roller, spray gun, dipping, or any other application technique able to wet the surface of the substrate.
A typical silicate solution for use in a fireproofing method of this invention may be made up as follows: Sodium silicate solution (18% by weight) 10 to 80 parts Sodium silicate power (commercial grade) 10 to 80 parts Pure silica powder 25 to 60 parts.
The above proportions are not critical and may be varied significantly, within the specified ranges, without any serious amelioration in the resultant fireproofing properties.
The solution may also contain one or more of the following, depending upon the precise required properties and the nature of the substrate being treated: exfoliated graphite, sodium methyl silicate, potassium silicate, an emulsifying agent (such as that marketed under the trade name Emulan by BASF), and a chlorinated paraffin.
Example 1 A silicate solution was made up in accordance with the following formula: Sodium silicate solution (18% by weight) 60 parts Commercial grade sodium silicate powder 15 parts Pure silicate powder 25 parts This solution was liberally coated by brush on a sheet of thin cardboard, and was then dried by the application of hot air thereto. The surface of the sheet was then wetted again with the solution, and a fibre-glass tissue was placed on to the wetted surface.
The second coat of the solution was dried by bringing a heated platen into contact with the fibre-glass tissue, and as soon as the tissue had been dried, a coat of thin cellulose varnish was applied to the tissue. The fibre-glass tissue acted as a key for the cellulose varnish.
The completed fire-proofing coating was tested for its water resilience by placing a ring of 150mm diameter and 25mm height on the surface (when horizontal), and filling that ring with water. After two days, no water penetration had been observed through the coating, to the substrate.
The substrate was then supported appropriately and the flame from a butane blow lamp was directed on to the treated surface of the substrate, for a period of thirty minutes. On subsequently inspecting the substrate, no burning thereof was observed, but the fibre-glass tissue had lifted locally from the substrate and had been baked away. The dried silicate had begun to entumesce as a result of the applied heat, so rising the surface and acting as a fire barrier.
Example 2 Sheets of news print were wetted using the same silicate solution as described above in Example 1, and the wetted sheets were laminated together to a thickness of about 3mm. Further samples were prepared with laminated thicknesses of up to 50mm. At the completion of the laminating process, a further final coating of the silicate solution was applied to the surface of the laminate and caused to dry by the application of hot air. A waterproof barrier layer was then applied to the surface of each sample; various barrier layers were tried, including cellulose varnish, a clear drying liquid wax, an oil bound undercoat paint, and also products marketed under the names Dow Corning 772 Silicon and Portafleck glaze coating.
Each sample of the laminate was found to be a very strong and could be used as a fire-proof constructional fibre board having excellent fire-proof qualities and also complete water resistance. In tests similar to those described above in Example 1, each sample of the board withstood the application of a butane flame, without suffering any burning after 30 minutes.
Other absorbent sheet-like materials besides newsprint may be laminated in this way - for example fibre-glass matting, paper tissue, or thin card-board.
Example 3 A silicate solution treatment was made up in accordance with the following formula: sodium silicate solution (18% by weight) 40 to 70 parts sodium silicate powder (commercial grade) 25 to 60 parts *Rustyns Plastic Coating including hardener 10 to 50 parts *Rustyns Plastic Coating is a furniture varnish which provides a hard and durable coating when applied to substrates such as wooden surfaces.
The silicate solution described above was stirred to emulsify the chemicals and was then applied to a substrate. Samples of the wetted substrates were dried using a hot air blast, ultra violet light, and a microwave oven. In each case, when the solution had fully dried, it was found that the plastic coating had risen to the surface of the silicate coating, forming a continuous membrane-like seal over the surface of the silicate coating, so furnishing a waterproof barrier layer preventing the absorption of moisture by the silicate coating. In this way, the waterproof barrier layer had been applied to the silicate coating concurrently with the forced drying of the silicate solution.
Example 4 A silicate solution was made up in accordance with the following formula: Potassium silicate solution 40 to 60 parts Sodium silicate solution 40 to 60 parts Poly-vinyl alcohol adhesive solution 20 to 25 parts Pure silica powder 10 to 20 parts Rustyns Plastic Coating including hardener 10 to 50 parts The above coating solution was applied in much the same way as has been described above in Example 3, but in view of the presence of the PVA adhesive, it was found that the solution was particularly suitable for use on non-porous substrates. Again, excellent fire-.
proofing properties were imparted to such substrates and the waterproof barrier layer was formed concurrently with the forced drying step of the solution.
Again, for use on non-porous surfaces, PVA clear adhesive may be added to the formula of Example 3 above.
Example 5 A solution was made up in accordance with the following formula: Lafarce fire cement 40 to 80 parts sodium silicate solution 40 to 80 parts sodium silicate powder 40 to 50 parts PVA adhesive 10 to 15 parts Rustyns Plastic Coating including hardener 10 to 15 parts.
The above silicate composition was been found to be particularly suitable for use on cementitious and like substrates, such as cement rendering, plasterboard, and so on. Once the surface had been fully treated, it was found both to waterproof the surface and to fire-proof it; in particular, it was found to minimise the explosive action which often otherwise occurs when cementitious surfaces are subjected to temperatures in excess of 15000C.
