Description
Isolant thermique exempt d’ammonium L’objet de l’invention est un isolant thermique à protection contre le feu, comprenant 80 - 95 % en poids de vieux papier en tant qu’isolant et 5 à 15 % en poids d’agent ignifuge pulvérulent, l’agent ignifuge ne contenant pas de bore ni de composés contenant du bore.
Pour augmenter l’efficacité énergétique dans les bâtiments, ces dernières années on accorde une attention particulière à une bonne isolation thermique. Pour l’isolation thermique on utilise des matériaux inorganiques, tels que la laine de verre ou de roche, ou des matériaux organiques, tels que le polystyrène expansé et la laine de mouton, ou des matériaux contenant de la cellulose, tels que la sciure de bois, le liège ou le feutre. A partir de processus de recyclage on obtient du papier journal défibré, qui est utilisé comme isolant thermique. Un inconvénient des matériaux isolants à base de vieux papier réside dans la combustibilité et le grand risque d’inflammation.
Pour cette raison, les isolants thermiques à base de vieux papier doivent être munis d’une protection contre le feu, de manière à satisfaire aux exigences qui sont imposées à un tel produit. Comme agents ignifuges on utilise à l’heure actuelle principalement des sels de bore. Ces derniers sont toutefois classés comme toxiques pour la reproduction et ont été enregistrés comme « subject of very high concern » dans la liste des candidats du règlement Reach. Ils sont donc considérés comme non souhaitables dans un produit écologique, tel que le représente l’isolation parallèle avec des flocons de cellulose à base de vieux papier. C’est pourquoi dans le vieux papier on a utilisé jusqu’à présent comme remplacement des sels d’ammonium en tant qu’agent ignifuge. Une autre restriction importante résulte maintenant d’un nouveau règlement de l’UE 2016/2017 du 23.06.2016, qui prévoit une interdiction des sels d’ammonium en tant que composant ignifuge dans les matériaux isolants cellulosiques.
En raison de leur composition chimique, la plupart des agents ignifuges traditionnels utilisés doivent donc être considérés comme critiques pour ce qui concerne la toxicité, l’impact sur l’environnement ainsi que la dégradabilité.
Le problème était par conséquent de fournir un isolant thermique respectueux de l’environnement, à base de vieux papier avec un agent ignifuge, qui évite les inconvénients précités et soit sans risque, en particulier toxicologique, et légalement autorisé.
Le problème est résolu selon l’invention par un isolant thermique à protection contre le feu qui comprend - 85 à 95 % en poids de vieux papier en tant qu’isolant et - 5 à 15 % en poids d’agent ignifuge pulvérulent. L’agent ignifuge ne contient selon l’invention pas de bore, pas de composés contenant du bore et est exempt de sels d’ammonium. L’agent ignifuge dans l’isolant thermique selon l’invention contient - 15 à 100 % en poids de perlite, - 0 à 85 % en poids d’un ou de plusieurs additif(s) synergique(s) choisi(s) dans l’ensemble constitué par - des composés contenant du phosphore, - des composés organiques contenant de l’azote, - des composés azotés-phosphorés organiques et - le sulfate de magnésium, le bicarbonate de sodium, le sulfate de lysine, le carbonate de calcium, le carbonate, de sodium, le citrate de sodium, l’hydroxyde d’aluminium, l’hydroxyde de magnésium, le sulfure de zinc, le phosphinate de sodium, le chlorure de magnésium, le sulfate de calcium, le carbonate de calcium et de magnésium. L’expression « vieux papier » est bien connue de l’homme du métier dans l’industrie du papier. Cette expression est surtout employée en lien avec le recyclage du papier. Plus particulièrement, au sens de la présente invention, on entend par “vieux papier” tout type de déchets de papier ou de papiers usagés, tels que les journaux, les magasines, les emballages ou les déchets issus du recyclage du papier. L’isolant thermique selon l’invention contient de préférence 85 à 95 % en poids de vieux papier et 5 à 15 % en poids d’agent ignifuge, de façon particulièrement préférée 85 à 95 % en poids de vieux papier et 5 à 15 % en poids d’agent ignifuge, la somme des composants étant égale à 100 % en poids.
Dans l’isolant thermique selon l’invention l’agent ignifuge est constitué de préférence de jusqu’à 100 % en poids de perlite ou est complété dans la gamme de 20 à 50 % en poids par des additifs à effet synergique. Dans un autre mode de réalisation, l’agent ignifuge peut être constitué de 15 à 100 % en poids de perlite et peut en outre être complété dans la plage de 20 à 85 % en poids par des additifs appropriés. On utilise de préférence des quantités de 30 - 50 % d’additifs et de 70 à 50 % en poids de perlite.
Dans un mode de réalisation, l’agent ignifuge contient selon l’invention 1 à 100 ppm d’une ou de plusieurs substance(s) à action biocide. On ajoute les substances à action biocide pour protéger l’isolant final contre l’attaque de champignons. On ajoute ces substances de préférence en une très faible proportion de 1 - 100 ppm. Parmi celles-ci on peut citer de façon particulièrement préférée les sels d’argent. L’agent ignifuge contient selon l’invention de préférence 20 -85 % en poids, de façon particulièrement préférée 30 à 50 % en poids d’additifs synergiques et 15 - 80 % en poids, de façon particulièrement préférée 50 - 70 % en poids, de perlite.
Dans un mode de réalisation de l’isolant thermique selon l’invention, la somme des composants perlite, additifs synergiques et éventuellement biocide de l’agent ignifuge est égale à 100 % en poids.
De façon particulièrement préférée l’agent ignifuge a selon l’invention l’une des compositions suivantes/ A : 100 % en poids de perlite ou B : 50 - 70 % en poids de perlite et 20 - 30 % en poids de composés inorganiques phosphorés et 10 - 20 % en poids de composés azotés-phosphorés organiques. L’objet de l’invention est en outre l’utilisation d’un vieux papier contenant un agent ignifuge pulvérulent qui contient - 15 - 100 % en poids de perlite, - 0 à 85 % en poids d’un ou de plusieurs additif(s) synergique(s) choisi(s) dans l’ensemble constitué par des composés contenant du phosphore, des composés organiques contenant de l’azote, des composés azotés-phosphorés organiques et le sulfate de magnésium, le bicarbonate de sodium, le sulfate de lysine, le carbonate de calcium, le carbonate de sodium, le citrate de sodium, l’hydroxyde d’aluminium, l’hydroxyde de magnésium, le sulfure de zinc, le phosphinate de sodium, le chlorure de magnésium, le sulfate de calcium, le carbonate de calcium et de magnésium, - ne contient pas de composés d’ammonium et - ne contient pas de bore ni de composés contenant du bore, en tant qu’isolant thermique. L’agent ignifuge utilisé selon l’invention correspond à l’agent ignifuge utilisé dans l’isolant thermique selon l’invention. Ainsi, selon un mode de réalisation, l’agent ignifuge utilisé selon l’invention contient un ou plusieurs composé(s) contenant du phosphore, choisi(s) dans l’ensemble constitué par le dihydrogénophosphate de sodium, le monohydrogénophosphate de sodium, le phosphate trisodique, le dihydrogénophosphate de potassium, le monohydrogénophosphate de potassium, le phosphate tripotassique, le phosphate monocalcique, le phosphate dicalcique, le phosphate tricalcique, le dihydrogénophosphate de magnésium, l’hydrogénophosphate de magnésium, le diphosphate disodique, le diphosphate trisodique, le diphosphate tétrasodique, le diphosphate tétrapotassique, le diphosphate dicalcique, le dihydrogénophosphate de calcium, le triphosphate pentasodique, le triphosphate pentapotassique, le polyphosphate de sodium, le polyphosphate de potassium, le polyphosphate de sodium et de calcium, le polyphosphate de calcium, le phosphate de fer, le phosphate de magnésium, le phosphate d’aluminium et des mélanges de ceux-ci.
Dans une autre réalisation, l’agent ignifuge utilisé selon l’invention contient également un ou plusieurs composé(s) organique(s) contenant de l’azote, choisi(s) dans l’ensemble constitué par la mélamine. la guanidine, l’urée et la 1-cyanoguanidine, la benzoguanidine et des mélanges de celles-ci. En outre, dans une réalisation, l’agent ignifuge utilisé selon l’invention contient un ou plusieurs composé(s) phosphoré(s) contenant de l’azote, choisi(s) dans l’ensemble constitué par le phosphate d’urée, le phosphate de mélamine, le polyphosphate de mélanine, le cyanurate de mélamine, le phosphate de guanidine et des mélanges de ceux-ci.
Au lieu ou en plus de tels composés, dans une réalisation l’agent ignifuge utilisé selon l’invention contient comme additifs synergiques un ou plusieurs composé(s) choisi(s) dans l’ensemble constitué par le phosphate de magnésium, le phosphate d’aluminium, le phosphate dicalcique, le phosphate disodique, le monohydrogénophosphate de sodium, le polyphosphate de sodium, le phosphate de calcium et de magnésium, le phosphate de mélamine, le phosphate de guanidine, le polyphosphate de mélamine, le phosphate d’urée, le cyanurate de mélamine, la mélamine, la 1-cyanoguanidine, le carbonate de calcium et le sulfate de magnésium. L’agent ignifuge utilisé selon l’invention contient de préférence 1 à 100 ppm d’une ou de plusieurs substance(s) à action biocide. L’agent ignifuge utilisé selon l’invention est constitué de préférence de perlite, d’additifs synergiques et éventuellement de biocide, la somme de ces composants de l’agent ignifuge étant égale à 100 % en poids.
Il existe différentes sortes de perlite. En premier lieu il y a la perlite dite brute, qui a son origine dans la lave volcanique, où elle est rapidement refroidie au contact de l’eau (sous forme de vapeur) sous une pression extrême. Elle appartient au groupe des rhyolithes, était anciennement également dénommée porphyre quartzifère et est comptée parmi les roches, La perlite brute est un silicate d’aluminium et avec plus de 70 pour cent présente une extrêmement forte teneur en dioxyde de silicium. En second lieu il y a la perlite expansée. La perlite brute a une densité apparente d’environ 900 - 1 000 kg/m3, et par calcination à environ 800 - 1 000 °C elle subit une expansion de 15 à 20 fois son volume initial et a alors une densité apparente de 50 à 100 kg/m3. Les variétés de perlite brute et expansée conviennent selon l’invention aussi bien l’une que l’autre à l’utilisation en tant qu’agent ignifuge.
Une composition chimique type de perlite est (% en poids) :
En tant qu’additifs synergiques à la perlite, on utilise selon l’invention les composés suivants : -Des composés contenant du phosphore
On peut utiliser aussi bien des composés phosphorés inorganiques que des composés phosphorés organiques ou des mélanges de ces deux types de composés. Comme exemples d’additifs contenant du phosphore de l’agent ignifuge selon l’invention, on peut citer : le dihydrogénophosphate de sodium, le monohydrogénophosphate de sodium, le phosphate trisodique, le -dihydrogénophosphate de potassium, le monohydrogénophosphate de potassium, le phosphate tripotassique, le phosphate monocalcique, le phosphate dicalcique, le phosphate tricalcique, le dihydrogénophosphate de magnésium, l’hydrogénophosphate de magnésium, le diphosphate disodique, le diphosphate trisodique, le diphosphate tétrasodique, le diphosphate tétrapotassique, le diphosphate dicalcique, le dihydrogénophosphate de calcium, le triphosphate pentasodique, le triphosphate pentapotassique, le polyphosphate de sodium, le polyphosphate de potassium, le polyphosphate de sodium et de calcium, le polyphosphate de calcium, le phosphate de fer, le phosphate de magnésium, le phosphate
d’aluminium. Les phosphates de calcium et de magnésium sont particulièrement préférés.
Les composés contenant du phosphore servent à la formation d’une couche superficielle carbonisée, consolidée, de composés phosphorés. En outre, dans certains cas, ils interrompent le mécanisme de réaction en chaîne du processus de combustion au sein de la phase gazeuse. L’agent ignifuge est converti en acide phosphorique par la décomposition thermique et de l’eau est extraite du substrat par pyrolyse. Il se forme ainsi une couche protectrice d’acide polyphosphorique et de carbone. -Des composés phosphorés contenant de l’azote
Des composés organiques phosphorés qui contiennent non seulement de l’azote mais également du phosphate se sont avérés particulièrement appropriés. Ceux-ci comprennent en particulier le phosphate d’urée, le phosphate de mélamine, le polyphosphate de mélamine, le cyanurate de mélamine, le phosphate de guanidine. -Des composés contenant de l’azote
Des composés organiques qui contiennent seulement de l’azote sont également appropriés. Ceux-ci comprennent en particulier : la mélamine, la guanidine, l’urée et la 1-cyanoguanidine, la benzoguanidine.
Ces composés peuvent agir dans la phase gazeuse par libération de gaz inertes (ammoniac, azote) ou provoquer par des réactions..de condensation des carbonisations de la phase solide.
En tant qu’additifs à effet synergique, les substances suivantes se sont également avérées efficaces : le sulfate de magnésium, le bicarbonate de sodium, le sulfate de lysine, le carbonate de calcium, le carbonate de sodium, le citrate de sodium, l’hydroxyde d’aluminium, l’hydroxyde de magnésium, le sulfure de zinc, le phosphinate de sodium, le chlorure de magnésium, le sulfate de calcium, le carbonate de calcium et de magnésium.
Ces additifs provoquent par la consommation d’énergie une décomposition endothermique, par exemple par évaporation de l’eau liée, de sorte que le matériau est refroidi, ou par la libération de gaz étouffant les flammes (dioxyde de carbone par exemple).
Les additifs synergiques sont utilisés seuls ou en mélange de divers additifs ou en mélange des différents groupes. L’isolant thermique selon l’invention doit être considéré comme une nouveauté respectueuse de l’environnement, qui en outre est exempte de sels d’ammonium et présente un plus haut degré d’efficacité que les isolants thermiques à agents ignifuges selon l’état de la technique. L’agent ignifuge peut être appliqué sur le vieux papier selon - -des méthodes connues. Par exemple, on peut mélanger l’agent ignifuge avec l’isolant à base de vieux papier dans des broyeurs appropriés, lors de l’effilochage. Dans ce cas, l’agent ignifuge se trouve sous forme de poudre sèche.
On a constaté de façon inattendue qu’en utilisant de la perlite (roche volcanique), il était possible de parvenir à une protection extrêmement forte contre le feu pour des isolants à base de vieux papier. La perlite est une roche volcanique naturelle non combustible et exempte de substances nocives, qui est formée lorsque du magma liquide entre en contact avec de l’eau à l’abri de l’oxygène. Les propriétés ignifuges peuvent en outre être encore améliorées par une association convenable de différents additifs à effet synergique. On peut ainsi parvenir à une meilleure protection contre le feu* plus -respectueuse de l’environnement, que celle connue dans l’état de la technique. Cela n’était pas prévisible car les principales applications de la perlite résidaient avant tout dans les domaines d’utilisation industrie du bâtiment pour l’isolation phonique ou la construction légère, industrie des produits alimentaires en tant que matériau filtrant dans la fabrication de la bière, de boissons rafraîchissantes et d’huile de table, industrie pharmaceutique pour la filtration d’antibiotiques, agriculture pour l’amélioration des sols, le traitement des engrais liquides, les produits phytosanitaires et protection de l’environnement pour la collecte des hydrocarbures répandus à la surface de l’eau et filtration de l’eau dans les piscines. Il était inattendu que la perlite soit remarquablement appropriée pour l’utilisation dans des isolants à base de vieux papier.
Un autre avantage de la perlite réside dans les coûts d’approvisionnement relativement faibles et la présence inépuisable et la formation par activité volcanique sur tout le globe. Puisqu’il s’agit d’une matière première purement minérale, elle est écologique et durable, et par conséquent convient remarquablement à des isolants qui proviennent d’un processus de recyclage.

Essai de réaction au feu
Les essais de réaction au feu ont été effectués dans un dispositif d’essai de réaction au feu selon DIN ISO 11925-2 pour la détermination de la classe de matériau B2 (normalement inflammable). On a introduit les isolants thermiques avec les compositions d’agents ignifuges A à J dans les supports d’échantillons (godets pour matières en vrac) et on les a fixés verticalement dans la boîte de combustion sur le dispositif de support. On a ensuite enflammé pendant 15 secondes à l’aide d’un brûleur incliné à un angle de 45°. On a mesuré l’étendue de carbonisation (cône de feu, matériau carbonisé), ainsi qu’une éventuelle postcombustion et une éventuelle postproduction de fumée. L’essai est considéré réussi si l’étendue de carbonisation de 15 cm n’est pas dépassée. On a en outre observé la postcombustion et la postproduction de fumée, mais à l’heure actuelle ce ne sont pas des paramètres qui sont requis pour la réussite de l’essai selon la classe de matériau B2.
Les résultats sont récapitulés dans le tableau suivant :
L’inclusion requise dans la classe de matériau B2 a donc pu être atteinte pour toutes les compositions d’agents ignifuges à base de perlite, exemptes d’ammonium, selon l’invention.
Ammonium-free thermal insulation The object of the invention is a thermal insulation with fire protection, comprising 80 - 95% by weight of old paper as insulation and 5-15% by weight of powdered flame retardant the flame retardant does not contain boron or boron-containing compounds.
To increase energy efficiency in buildings, special attention has been paid in recent years to good thermal insulation. For thermal insulation inorganic materials, such as glass wool or rock wool, or organic materials, such as expanded polystyrene and sheep wool, or materials containing cellulose, such as sawdust, are used. wood, cork or felt. From the recycling process, defibrated newsprint is obtained, which is used as thermal insulation. A disadvantage of old paper insulating materials is the combustibility and high risk of ignition.
For this reason, thermal insulation based on old paper must be provided with fire protection, so as to meet the requirements that are imposed on such a product. As flame retardants, at present mainly boron salts are used. These are, however, classified as toxic for reproduction and have been registered as "subject of very high concern" in the Reach list of candidates. They are therefore considered undesirable in an ecological product, as represented by the parallel insulation with cellulose flakes based on old paper. This is why in old paper has been used until now as replacement of ammonium salts as flame retardant. Another important restriction now results from a new EU regulation 2016/2017 of 23.06.2016, which provides for a ban on ammonium salts as a flame retardant component in cellulosic insulation materials.
Because of their chemical composition, most traditional flame retardants used should therefore be considered critical for toxicity, environmental impact and degradability.
The problem was therefore to provide an environmentally friendly thermal insulation, based on old paper with a flame retardant, which avoids the aforementioned disadvantages and is safe, especially toxicological, and legally permitted.
The problem is solved according to the invention by a fire-resistant thermal insulator which comprises - 85 to 95% by weight of old paper as insulation and - 5 to 15% by weight of powdered fireproofing agent.

There are different kinds of perlite. In the first place there is the so-called raw pearlite, which has its origin in volcanic lava, where it is rapidly cooled in contact with water (in the form of steam) under extreme pressure. It belongs to the group of rhyolites, was formerly also called quartz porphyry and is counted among the rocks, The raw perlite is an aluminum silicate and with more than 70 percent has an extremely high content of silicon dioxide. In the second place there is expanded perlite. Crude perlite has an apparent density of about 900 - 1000 kg / m3, and by calcination at about 800 - 1000 ° C it expands 15 to 20 times its initial volume and then has a bulk density of 50 to 100 kg / m3. The varieties of raw and expanded perlite are suitable according to the invention both for use as a flame retardant.
A typical chemical composition of perlite is (% by weight):
As synergistic additives to perlite, the following compounds are used according to the invention: compounds containing phosphorus
Both inorganic phosphorus compounds and organic phosphorus compounds or mixtures of these two types of compounds can be used. As examples of phosphorus-containing additives of the flame retardant according to the invention, mention may be made of: sodium dihydrogenphosphate, sodium monohydrogenphosphate, trisodium phosphate, potassium dihydrogenphosphate, potassium monohydrogenphosphate, tripotassic phosphate , monocalcium phosphate, dicalcium phosphate, tricalcium phosphate, magnesium dihydrogen phosphate, magnesium hydrogen phosphate, disodium diphosphate, trisodium diphosphate, tetrasodium diphosphate, tetrapotassium diphosphate, dicalcium diphosphate, calcium dihydrogen phosphate, pentasodium triphosphate, pentapotassium triphosphate, sodium polyphosphate, potassium polyphosphate, sodium and calcium polyphosphate, calcium polyphosphate, iron phosphate, magnesium phosphate, phosphate
aluminum. Calcium and magnesium phosphates are particularly preferred.
Phosphorus-containing compounds are used to form a consolidated, carbonized surface layer of phosphorus compounds. In addition, in some cases, they interrupt the chain reaction mechanism of the combustion process within the gas phase. The flame retardant is converted to phosphoric acid by thermal decomposition and water is extracted from the substrate by pyrolysis. A protective layer of polyphosphoric acid and carbon is thus formed. Phosphorus compounds containing nitrogen
Organic phosphorus compounds which contain not only nitrogen but also phosphate have proved particularly suitable. These include, in particular, urea phosphate, melamine phosphate, melamine polyphosphate, melamine cyanurate, guanidine phosphate. -Nitrogen-containing compounds
Organic compounds that contain only nitrogen are also suitable. These include in particular: melamine, guanidine, urea and 1-cyanoguanidine, benzoguanidine.
These compounds can act in the gas phase by the release of inert gases (ammonia, nitrogen) or by condensation reactions of the carbonizations of the solid phase.
As synergistic additives, the following substances have also been shown to be effective: magnesium sulphate, sodium bicarbonate, lysine sulphate, calcium carbonate, sodium carbonate, sodium citrate, aluminum hydroxide, magnesium hydroxide, zinc sulfide, sodium phosphinate, magnesium chloride, calcium sulfate, calcium carbonate and magnesium.
These additives cause by the energy consumption an endothermic decomposition, for example by evaporation of the bound water, so that the material is cooled, or by the release of gas smothering the flames (carbon dioxide for example).
Synergistic additives are used alone or as a mixture of various additives or as a mixture of different groups. The thermal insulation according to the invention must be considered as an environmentally friendly novelty, which is furthermore free from ammonium salts and has a higher degree of efficiency than flame retardant thermal insulators according to the state. of the technique. The flame retardant may be applied to the old paper according to known methods. For example, the flame retardant can be mixed with the old paper insulation in suitable grinders during fraying. In this case, the flame retardant is in the form of a dry powder.
It was unexpectedly found that using perlite (volcanic rock), it was possible to achieve extremely strong fire protection for old paper-based insulation. Perlite is a natural, non-combustible, no-harmful, volcanic rock that is formed when liquid magma comes into contact with oxygen-free water. The flame retardant properties can further be further improved by a suitable combination of different synergistic additives. In this way, it is possible to achieve better protection against fire * which is more environmentally friendly than that known in the state of the art. This was not foreseeable as the main applications of perlite were primarily in the areas of use building industry for sound insulation or lightweight construction, food industry as a filter material in the manufacture of beer , refreshing beverages and table oil, pharmaceutical industry for the filtration of antibiotics, agriculture for soil improvement, liquid fertilizer treatment, phytosanitary products and environmental protection for the collection of hydrocarbons spilled at the surface of the water and filtration of water in the pools. It was unexpected that perlite is remarkably suitable for use in old paper insulation.
Another advantage of pearlite is the relatively low supply costs and the inexhaustible presence and formation by volcanic activity around the globe. Since it is a purely mineral raw material, it is environmentally friendly and durable, and therefore is remarkably suitable for insulators that come from a recycling process.

Fire reaction test
Reaction to fire tests were carried out in a DIN ISO 11925-2 fire reaction test device for the determination of material class B2 (normally flammable). The thermal insulators with the flame retardant compositions A to J were introduced into the sample holders (bulk material buckets) and fixed vertically in the combustor on the support device. It was then ignited for 15 seconds with a burner inclined at a 45 ° angle. The extent of carbonization (fire cone, charred material) was measured, as well as a possible post-combustion and possible post-production of smoke. The test is considered successful if the extent of charring of 15 cm is not exceeded. In addition, post-combustion and post-production of smoke have been observed, but at present these are not parameters that are required for the success of the test according to material class B2.
The results are summarized in the following table:
The inclusion required in the B2 material class could thus be achieved for all ammonium-free perlite flame retardant compositions according to the invention.
