Abstract

This material consists of fibrous residues of the leaves of posidonia which are agglomerated under pressure with a compatible binder. This material is usable especially for the production of antifire walls.

Description

Matériau aggloméré à haut degré d'ininflammabilité.  Agglomerated material with a high degree of flammability.

La présente invention a pour but de créer un matériau aggloméré à base d'une substance fibreuse d'origine végétale présentant un haut degré d'ininflammabilité, c'est-à-dire résistant notam- ment à la flamme du chalumeau et plus généralement à des tempé- ratures atteignant 1000 degrés centigrades. Ce but paraissait pratiquement impossible à atteindre avec des substances fibreuses d'origine végétale dont une caractéristique est la combustibilité- sans incorporation de quantité économiquement prohibitive de substances ignifuges.The object of the present invention is to create an agglomerated material based on a fibrous substance of vegetable origin having a high degree of non-flammability, that is to say resistant in particular to the flame of the torch and more generally to temperatures reaching 1000 degrees centigrade. This goal seemed practically impossible to achieve with fibrous substances of vegetable origin, one characteristic of which is combustibility - without the incorporation of an economically prohibitive quantity of flame retardants.

Le matériau aggloméré à haut degré d'ininflammabilité conforme à l'invention est caractérisé en ce qu'il est constitué par des restes fibreux des feuilles de posidonies agglomérés sous pression avec un liant compatible.The agglomerated material with a high degree of flammability in accordance with the invention is characterized in that it consists of fibrous remains of the sheets of posidonia agglomerated under pressure with a compatible binder.

Les posidonies sont des herbes marines submergées à feuilles rubanées, fréquentes sous forme d'herbiers importants sur les côtes méditerranéennes. Les feuilles des posidonies constituent la majeure partie du goémon épave méditerranéen et elles peuvent s'accumuler après les tempêtes en quantité considérable sur les plages. L'utilisation de ces amas de feuilles desséchées de posidonies s'est surtout limitée jusqu'ici à l'emploi comme litière ou comme matériau d'emballage.Posidonia are submerged sea grasses with banded leaves, frequent in the form of important herbaria on the Mediterranean coasts. Posidonia leaves make up most of the Mediterranean wrecked seaweed and can accumulate after storms in considerable quantities on beaches. The use of these heaps of dried leaves of Posidonia has so far been mainly limited to use as litter or as packaging material.

A la suite d'observations sur la modification de la salinité de l'eau de mer dans les champs de posidonies, l'inventeur a émis l'hypothèse d'une fixation importante de minéraux en solution par les posidonies et notamment par les feuilles.Following observations on the modification of the salinity of sea water in the fields of Posidonia, the inventor put forward the hypothesis of a significant fixation of minerals in solution by the Posidonia and in particular by the leaves.

Les études effectuées sur les restes fibreux des feuilles constituant les amas de goémon épave ont confirmé cette minéralisation importante qui se traduit par une stabilisation physique de la fibre et l'extinction rapide de toute amorce de combustion, les résidus minéraux de la combustion formant en outre, sous une très faible épaisseur, une carapace incombustible.The studies carried out on the fibrous remains of the leaves constituting the clumps of wrecked seaweed have confirmed this significant mineralization which results in a physical stabilization of the fiber and the rapid extinction of any initiation of combustion, the mineral residues of combustion also forming , under a very small thickness, an incombustible shell.

Lorsque ce matériau est mis sous forme de plaques agglomérées, sous des pressions de l'ordre de 6 à 10kg/cm2, les feuilles lamellaires de posidonies se superposent à plat et sont stabilisées dans cette position par le liant, sans canaux internes notables entre feuilles, lesdits canaux ou interstices étant de préférence remplis par le liant. Une attaque d'une flamme incinère les feuilles formant la couche superficielle avec un reste de cendres salines qui forme une croûte auto-extinctrice.When this material is put in the form of agglomerated plates, under pressures of the order of 6 to 10 kg / cm2, the lamellar sheets of posidonia overlap flat and are stabilized in this position by the binder, without notable internal channels between sheets. , said channels or interstices being preferably filled with the binder. A flame attack incinerates the leaves forming the surface layer with a residue of salt ash which forms a self-extinguishing crust.

La nature du liant ne joue pas un rôle essentiel sur le degré d'ininflammabilité du matériau qui semble résulter de la forte minéralisation des feuilles. Il est donc possible d'utiliser d'une manière générale toutes les colles pour substances végétales compatibles avec une forte teneur en chlorure de sodium.The nature of the binder does not play an essential role on the degree of flammability of the material which seems to result from the strong mineralization of the leaves. It is therefore possible to use in general all the adhesives for vegetable substances compatible with a high content of sodium chloride.

On peut donc utiliser une colle blanche à bois ou des liants phénoliques. Selon un mode de réalisation préférentiel, on utilise une colle vinylique à raison de 0,5kg par décimètre cube d'aggloméré. Le volume du liant doit être de préférence tel qu'il assure un remplissage des interstices subsistant entre les feuilles après pressage. We can therefore use a white wood glue or phenolic binders. According to a preferred embodiment, a vinyl adhesive is used at a rate of 0.5 kg per cubic decimeter of agglomerate. The volume of the binder should preferably be such that it fills the gaps remaining between the sheets after pressing.
