Description

This invention relates to the use of a stabilizer which significantly enhances the compatibility of the binder (polymer dispersion) with the liquid ammonium polyphosphate, called APP for short, in a flame-retardant coating composition. In this flame-retardant composition, the liquid ammonium polyphosphate functions as active flame retardant. The flame-retardant coating compositions are highly suitable for all kinds of textiles, but also for paper, leather and fiber materials. The purpose of flame retardants is to retard the igniting of combustible materials, such as plastics, textiles or wood, and to slow down or prevent entirely the spreading of flames. The subject matter relates to different chemical compounds which can be used, for example, in the plastic casings used for televisions and computers, in textiles used in living spaces, and in foam materials used for the insulation and assembly.
The following types of flame-retardants are known from the prior art:

halogenated flame retardants
nitrogen-based flame retardants
organophosphorus flame retardants
inorganic flame retardants

A frequently occurring phenomenon is the burning of textiles, e.g. in lodgings containing carpets, furniture or home textiles. However, clothing and especially that of firemen, children or also kitchen personnel is frequently subjected to the danger of fire. Textiles which must be flame retardant play an important role in many industrial processes. The flame-retarding properties of seat covers and upholstery, as well as floor coverings, furthermore represent an extremely important safety requirement for public transportation means.
Several options exist for attempting to extinguish a textile material already on fire in order to prevent a further spread of the fire, which can simply be extinguished with the aid of water, or sand, or also with the aid of a blanket, or by using so-called dry chemical extinguishers which frequently contain sodium hydrogen-carbonate under carbon dioxide pressure. In that case, the mechanism for extinguishing the fire involves the smothering of the flame through the liberation of carbon dioxide which is formed as a result of the thermal decomposition of the sodium hydrogen-carbonate. The flame-retarding effect of phosphor-containing flame retardants is primarily the result of forming a cover layer and the dehydration or elimination of water in the condensed phase. Intumescent paints which contain powdered ammonium polyphosphate primarily work by generating foam to insulate against heat. Compositions for flame-retardant coatings used on textiles or other materials are known from the prior art, as mentioned in the above. In addition to a halogen-containing active flame retardant, for example, they contain a binder. The binder as a rule is composed of an aqueous polymer dispersion, for example composed of the following polymers: polyurethane, poly-acrylate or vinyl chloride copolymers. As further components, these compositions contain auxiliary agents such as cross-linking agents, foam stabilizers, thickening agents and active flame-retarding agents, for example organic bromine and/or chlorine compounds. These agents are in part ecologically problematic, especially the bromine-containing flame retardants, which include poly-brominated diphenylether (PBDE), tetrabromo bisphenol A (TBBPA) and hexabromo cyclododecane (HBCD). They have long been used in the environment, but are difficult to break down and in part are also bio-accumulating, meaning they accumulate in living organisms. TBBPA and HBCD are toxic to organisms in the water. TBBPA and HBCD have already been detected in breast milk and in the blood of humans. TBBPA and HBCD are suspected of having long-term toxic effects. Several bills have been introduced to remove this agent from the market place.
The organophosphorus-containing flame retarding agents, typically aromatic and aliphatic esters of the phosphoric acid such as the ones listed below, are problematic with respect to the environment. Some of these agents are listed in the following.

TCEP (tris(chlorethyl)phosphate)
TDCPP (tris(dichlorisopropyl)phosphate)
TPP (triphenyl phosphate)
TEHP (tris-(2-ethylhexyl)phosphate)
TKP (tricresyl phosphate)
ITP (“isopropylated triphenyl phosphate”) mono-, bis- and tris(isopropylphenyl)phosphates, having different degrees of isopropylation
RDP (resorcinol-bis(diphenyl phosphate))
BDP (bisphenol-A-bis(diphenyl phosphate))

These flame retardants are used, for example, with soft and hard polyurethane foam materials, for example in upholstered furniture, vehicle seats or building materials.
The known inorganic flame retardants, for example, include:

Aluminum hydroxide (Al(OH)3) which is the most widely used flame retardant worldwide (also called ATH for “aluminum trihydrate”). It has a cooling and gas-diluting effect as a result of the elimination of water, but must be added in large amounts (of up to 60%).
Magnesium hydroxide (Mg(OH)2), MDH, “magnesium dihydrate”) is a mineral-based flame retardant with higher temperature resistance than ATH, but with the same effect.
Ammonium sulfate ((NH4)2SO4) and ammonium phosphate ((NH4)3PO4) dilute the gas in the flame by eliminating ammonium (NH3) which is converted to water and different nitrogen oxides during the combustion, thereby removing oxygen from the flame. At the same time, they cause a protective layer to form as a result of the sulfuric acid (H2SO4) and/or the phosphoric acid (H3PO4), wherein these can interrupt the radical chain reaction as one of their functions. The acids are furthermore not burnable, are strongly hygroscopic and have high boiling points. For that reason, they condensate in the cooler region of the flame and are precipitated out onto the material. As a result of dehydration or elimination of water, metaphosphoric and poly-phosphoric acids also form from the phosphoric acid, which have even higher boiling points.
Red phosphorous forms a layer composed of phosphoric acid and poly-phosphoric acid on the surface, wherein this layer swells up (intumescence). The layer has an insulating effect and prevents oxygen from reaching the material. The phosphates formed in the process have the same properties as the ammonium polyphosphates resulting from the ammonium phosphate.
Antimony trioxide (Sb2O3) only functions as a synergist in combination with halogenated flame retarding agents. In cases of fire, it has the disadvantage of a catalytic effect resulting in dioxin development.
Antimony pentoxide (Sb2O5) functions also as a synergist, similarly as the Sb2O3.
Zinc borates (see borates), among other things, have a cooling and gas diluting effect resulting from the elimination of water. Zinc compounds, however, can also have a synergic effect and can in part replace the more dangerous antimony trioxide.
Calcium hydroxide (Ca(OH)2) was used during the Second World War as flame retarding agent for the wood in roof trusses. It initially binds carbon dioxide from the air as a result of the elimination of water and then changes to calcium carbonate (CaCO3). As a protective coating, it makes access more difficult.

Also known as active flame retardants are ammonium polyphosphate solutions. Ammonium polyphosphate solutions are introduced in the DE 10 021 027. These solutions are well suited for the aforementioned purpose, namely to provide all kinds of textiles with flame retarding properties. However, if these solutions are applied simply in the form of an aqueous solution to the textiles, they cannot penetrate deep enough into the fibers. In addition, if these textiles are treated with this solution, the textiles become very stiff and heavy, as well as blotchy and thus have reduced wearing ability. Over time and through repeated washings, the ammonium polyphosphate is washed out of the textile structures.
For the treatment of substrates, such as textiles, a suitable flame-retardant coating composition must therefore always be used which comprises, among other things, the binder (polymer dispersion) and a liquid ammonium polyphosphate. Different types of compounds are contained in the binders (polymer dispersions): The essential starting materials are synthetic monomers, a protective colloid and/or emulsifying agent, initiating agent. As a result of polymerization of the monomers, the respective binders take the form of polymer dispersions. These binders are responsible for the improved adhesion of the flame-retardant coating composition on substrates.
Binders (polymer dispersions) based on polyurethane, vinyl acetate, or poly acrylate, however, are incompatible with the liquid ammonium polyphosphate, which frequently leads to an irreversible coagulation and/or flocculation. This coagulation presumably occurs as a result of damage to the stabilizer system, consisting of protective colloid and emulsifying agent.
The object of the invention therefore was to find a possible solution for removing this incompatibility between the two components, namely the liquid ammonium polyphosphate and the binder (polymer dispersion).
Surprisingly, it was discovered that when using an alkyl benzene sulphonate, which is added to the binder (polymer dispersion), the phenomenon of coagulation and flocculation no longer occurs, that the polymer dispersions are easy to handle, and that the flame-retardant coating compositions produced therewith can be applied homogeneously and permanently to all substrates. The invention is specified in further detail in the following claims:

Within the framework of the present invention, liquid ammonium polyphosphate is understood to refer only to those compounds which were produced in the liquid form, meaning no solutions obtained by dissolving a powdered solid ammonium polyphosphate in water because powdered ammonium polyphosphates have a very low solubility in water which is only approximately 1%.
These alkyl benzene sulphonates stabilize the binder (polymer dispersion) to prevent coagulation in the flame-retardant coating compositions. The textile substrate treated with a composition of this type above all has an almost unchanged soft feel to it. This also entails good wearing characteristics for the articles of clothing produced from it and/or a good processing ability for the textiles, for example those used in the production of automobile covers or furniture covers. The invention in general relates to the finishing of all types of textiles, such as fabrics, crocheted or knitted fabrics, woven or nonwoven materials on the basis of natural fibers such as plant fibers, cellulose fibers, plant protein fibers, chemical pulp fibers, paper fibers, rubber fibers, and alginate fibers, as well as animal fibers in the form of wool and hair, leather and leather fibers, and also fibers on the basis of chemical fibers, polymerization fibers, poly condensation fibers and poly addition fibers. According to the invention, p-Cumol sulphonic acid in the form of its Na and/or K salts is particularly suitable for use as a stabilizer for the binder (polymer dispersion) in the flame-retardant coating compositions.
