La réglementation applicable en France définit quant à elle, également différents classements, d'une part caractérisés notamment par l'émission de fumées et identifiés par les lettres F0 à F5, F3 étant le meilleur comportement accessible par un matériau contenant un polymère halogéné, et d'autre part caractérisés notamment par la durée d'inflammation du tissu, et identifiés par les lettres M0 à M4, la lettre M1 identifiant le meilleur comportement au feu généralement accessible par un The regulations applicable in France also define different classifications, on the one hand characterized in particular by the emission of smoke and identified by the letters F0 to F5, F3 being the best behavior accessible by a material containing a halogenated polymer, and on the other hand, characterized in particular by the duration of inflammation of the tissue, and identified by the letters M0 to M4, the letter M1 identifying the best behavior in fire generally accessible by a

S'agissant de l'enduction d'un substrat, et en particulier de l'âme d'un fil, avec une composition plastique ignifugeante, comprenant une résine acrylique et un agent intumescent, la présente invention s'est posée la question du mode d'enduction le plus approprié, c'est-à-dire susceptible de préserver en final les propriétés du fil ou de la structure composite obtenue, en termes de thermo-soudabilité et de résistance aux With regard to the coating of a substrate, and in particular of the core of a wire, with a flame-retardant plastic composition, comprising an acrylic resin and an intumescent agent, the present invention has raised the question of the mode most suitable coating, that is to say ultimately capable of preserving the properties of the wire or of the composite structure obtained, in terms of heat-weldability and resistance to
basses comme aux températures élevées. low as at high temperatures.
Et s'agissant d'un fil, I'invention a d'abord retenu à cette fin une enduction, par passage de l'âme dans une filière, avec une distribution périphérique autour de l'âme d'une gaine de la composition plastique ignifugeante, à l'état de plastisol non gélifié, c'est-à-dire avec un milieu plastifiant dans lequel sont distribués, et la résine acrylique et l'agent intumescent. Cette voie d'apport de la composition plastique sur le substrat, c'est-à-dire avec un plastisol, évite de recourir à une fusion de la matière plastique, à température relativement élevée s'agissant d'une résine And in the case of a wire, the invention first retained a coating for this purpose, by passing the core through a die, with a peripheral distribution around the core of a sheath of the plastic composition. flame retardant, in the form of ungelled plastisol, that is to say with a plasticizing medium in which are distributed, and the acrylic resin and the intumescent agent. This route of supplying the plastic composition to the substrate, that is to say with a plastisol, avoids resorting to melting of the plastic material, at relatively high temperature in the case of a resin.

Mais ceci évite surtout de dégrader l'agent intumescent, et permet de But this especially avoids degrading the intumescent agent, and allows
limiter la proportion de ce dernier dans la composition de départ. limit the proportion of the latter in the starting composition.
Ensuite, I'invention identifie les conditions à respecter, pour que le plastisol puisse demeurer compatible avec des filières à défilement linéaire relativement important. A cette fin, selon l'invention, le plastisol est formulé en sorte que: - la viscosité demeure inférieure ou égale à 6000 m.Pa.s, mesurée avec un viscosimètre Brookfield RVT à 20 tours/mn; - son comportement rhéologique soit de type pseudo-plastique et newtonien. Préférentiellement, de manière à préserver les propriétés du fil de la structure composite obtenue, notamment sa thermo-soudabilité et sa résistance aux intempéries, en combinaison, la proportion pondérale du milieu plastifiant comprenant un phtalate est au plus égale à 200 % par rapport au poids de la résine acrylique, et la proportion pondérale de l'agent intumescent est au plus égale à 200 % par rapport au poids de résine Then, the invention identifies the conditions to be respected, so that the plastisol can remain compatible with relatively large linear scrolling dies. To this end, according to the invention, the plastisol is formulated so that: - the viscosity remains less than or equal to 6000 m.Pa.s, measured with a Brookfield RVT viscometer at 20 rpm; - its rheological behavior is of pseudo-plastic and Newtonian type. Preferably, so as to preserve the properties of the wire of the composite structure obtained, in particular its heat sealability and its resistance to weathering, in combination, the proportion by weight of the plasticizing medium comprising a phthalate is at most equal to 200% relative to the weight of acrylic resin, and the proportion by weight of the intumescent agent is at most equal to 200% relative to the weight of resin
acrylique.acrylic.
Le milieu plastifiant comporte majoritairement en poids un phosphate organique, avec éventuellement et préférentiellement un phtalate. La proportion pondérale de l'agent intumescent est comprise entre 50 et 200 %, et de préférence entre 150 et 200 % en poids de la résine. Tout fil composite ou toute structure composite textile, susceptible d'être obtenue par enduction puis gélification d'une composition ignifugeante telle que définie précédemment, permet d'atteindre une résistance au feu selon la norme française NFP 92503, notamment le niveau de classement Ml1, et également une bonne tenue aux intempéries vérifiant la norme ISO 105, et enfin une bonne thermosoudabilité. The plasticizing medium mainly comprises by weight an organic phosphate, with optionally and preferably a phthalate. The proportion by weight of the intumescent agent is between 50 and 200%, and preferably between 150 and 200% by weight of the resin. Any composite yarn or any textile composite structure, capable of being obtained by coating then gelling of a flame retardant composition as defined above, makes it possible to achieve fire resistance according to French standard NFP 92503, in particular the classification level Ml1, and also good weather resistance verifying the ISO 105 standard, and finally good heat sealability.

Exemple 1: Formulation I d'une composition plastique ignifugeante * Plastisol: - Résine acrylique (BM 310 de la Société AGOMER) 100.00 parties - Plastifiant phosphate/phtalate 125. 00 parties * Agent intumescent: Polyphosphate d'ammonium 120.00 parties - Pentaérythritol 31.00 parties Mélamine 31.00 parties * Lubrifiant: - Huile de silicone 2.50 parties Les tests de comportement au feu ont été réalisés sur des tissus de verre enduits par la composition plastique ignifugeante décrite ci-dessus, ainsi que sur des fils composites formés d'environ 54 % (ou 50 %) de silionne et de 46 % (ou 50 %) de composition plastique ignifugeante Example 1: Formulation I of a flame retardant plastic composition * Plastisol: - Acrylic resin (BM 310 from the company AGOMER) 100.00 parts - Phosphate / phthalate plasticizer 125.00 parts * Intumescent agent: Ammonium polyphosphate 120.00 parts - Pentaerythritol 31.00 parts Melamine 31.00 parts * Lubricant: - Silicone oil 2.50 parts The fire behavior tests were carried out on glass fabrics coated with the flame-retardant plastic composition described above, as well as on composite wires formed of approximately 54% ( or 50%) of silionne and 46% (or 50%) of flame retardant plastic composition
décrite ci-dessus.described above.
Les résultats des tests effectués permettent de montrer que le classement M1 de la norme NFP 92503 peut être attribué aux textiles ainsi obtenus. Exemple 2: Formulation Il d'une composition plastique ignifugeante * Plastisol - Résine acrylique (BM 310) de la Société AGOMER 100.00 parties - Plastifiant phosphate/phtalate 125.00 parties * Agent intumescent: Polyphosphate d'ammonium 38.00 parties - Pentaérythritol 31.00 parties Système ignifugeant BUDIT 3077B (commercialisé par la Société BUDENHEIM) 150. 00 parties * Lubrifiant: - Huile de silicone 2.50 parties The results of the tests carried out show that the M1 classification of standard NFP 92503 can be attributed to the textiles thus obtained. Example 2: Formulation II of a flame retardant plastic composition * Plastisol - Acrylic resin (BM 310) from the company AGOMER 100.00 parts - Phosphate / phthalate plasticizer 125.00 parts * Intumescent agent: Ammonium polyphosphate 38.00 parts - Pentaerythritol 31.00 parts BUDIT flame retardant system 3077B (sold by the company BUDENHEIM) 150.00 parts * Lubricant: - Silicone oil 2.50 parts
