Abstract

This invention relates to a method of treating a material to raise its ignition point comprising treating the material with a composition comprising ammonium polyphosphate. The invention also relates to a material having a surface treated with ammonium polyphosphate to raise the ignition point of the material at the surface.

Description

A METHOD FOR TREATING A SURFACE OF A COMBUSTIBLE MATERIAL This invention relates to a method of treating a surface of a combustible material to raise the ignition point (i.e. the temperature at which the material will combust) to fireproof the material.
Known methods of raising the ignition point of a material comprise applying a flame-retarding agent to a surface of the material. The protection against fire thus provided is only partial and most treated materials will burn when exposed to sufficiently high temperatures.
Certain flame-retarding agents, especially those comprising water-soluble organic salts, are easily removed by laundering or by accidental exposure to water.
There is a need, therefore, for a method of treating a surface of a material which provides a durable treatment with a flame-retarding agent.
According to one aspect of the invention there is provided a method of treating a material to raise its ignition point comprising treating the material with a composition comprising ammonium polyphosphate.
Preferably, it is a surface of the material that is treated.
It is preferred that the composition comprises a binding agent which binds the ammonium polyphosphate to the surface. The binding agent may be for example a polyvinyl acetate ethylene copolymer. If the material to be treated is a textile it is preferred that the composition comprises a penetrating agent which allows the ammonium polyphosphate to impregnate fibres of the textile.
The penetrating agent may be a surfactant e.g.
"Anionic-nonionic".
The surface may be treated by sponging, spraying or brushing with the composition. Alternatively, the material may be dipped in the composition.
The composition may further comprise an insecticide and/or a fungicide to render the treated surface resistant to insects and fungi. The insecticide may be an organophosphorous compound e.g.
chloropyrifos methyl. The fungicide may be a quaternary ammonium salt. The composition may be an emulsion and in which case it preferably further comprises an emulsifier to stabilize the emulsion.
Materials which may be treated by the method of the invention include for example: textiles such as wool, cotton, polyester, rayon or nylon; or other materials such as wood.
According to a further aspect of the invention there is provided a material having a surface treated with ammonium polyphosphate to raise the ignition point of the material at the surface.
The ammonium polyphosphate may penetrate into the material for example in the case of a porous material such as wood. Alternatively, the ammonium polyphosphate may be coated over the surface.
Preferably the ammonium polyphosphate is bound to the surface by a binding agent, e.g. a polyvinyl acetate ethylene copolymer.
A composition for use in the method of the invention will now be described by way of example only.
The. composition is formed as an emulsion mixing the components given in Table 1 and dispersing the mixture thus formed in the mixture of the compounds given in Table 2.
TABLE 1 Ammonium polyphosphate 68.5% Polyvinyl acetate ethylene copolymer 29.0% Chloropyrifos methyl A quaternary ammonium salt 1.0% 100. 0% TABLE 2 Distilled water 74.3% "Nonionic-anionic" 25.0% Vinyl acetate 0.5% Hydrogen peroxide 0.2% 100. 0% A typical composition will comprise 30% of components from Table 1 and 70% of components from Table 2. Such compositions have a translucent white appearance and at 15% have a pH of about 7.0 and a specific gravity of about 1.1.
The principle component of the composition is ammonium polyphosphate (also known as urea ammonium polyphosphate). The flame retarding properties of ammonium polyphosphate are both novel and unexpected.
The polyvinyl acetate ethylene copolymer is included in the composition as a binding agent. When the composition is'applied to a surface, especially a textile surface, the polyvinyl acetate ethylene copolymer binds the ammonium polyphosphate to the surface. The ammonium polyphosphate has been found to render the surface highly flame resistant. A textile material which has been treated with the composition is also rendered resistant to fraying.
Furthermore, the fibres of the textile surface are sealed by the polyvinyl acetate ethylene copolymer rendering them dirt resistant. The polyvinyl acetate ethylene copolymer ensures that the ammonium polyphosphate is held in a durable layer on the surface. In tests, textile surfaces have been treated with the compositions and the ammonium polyphosphate has withstood more than twleve dry cleaning cycles to British Standard No.3120.
Chloropyrifos methyl, which is an organophosphorous compound, is included in the composition as an insecticide. Textile and other surfaces treated with the composition are thus protected against infestation by insects e.g. fleas (Pulex irritans Pedicalii corpris, and Pediculus canitis)which are known to infest bus, coach and rail seats.
The quaternary ammonium salt is included as a fungicide to render the treated material resistant to rotting.
"Nonionic-anionic" is a surfactant which assists in dispersing the ammonium polyphosphates over the surface to be treated, and where the material is a textile, assists in impregnating the fibres of the textile.
Vinyl acetate is a textile finishing agent which assists in binding the ammonium polyphosphate to the surface.
The composition is particularly advantageous in that its components have a low order of toxicity and present no especial hazards in storage and handling.
