Description
Matériau composite isolant acoustiquement et thermiquementAcoustically and thermally insulating composite material
La présente invention concerne un matériau composite isolant acoustiquement et thermiquement.The present invention relates to an acoustically and thermally insulating composite material.
Dans la construction immobilière, automobile, aéronautique, ferroviaire et navale, on utilise depuis longtemps des isolants thermiques et acoustiques. Souvent ces isolants sont faits de laines minérales ou autres produits qui peuvent être nocifs lors de leur manipulation et/ou de leur utilisation ou lors de la destruction. La prise de conscience de ces inconvénients a poussé les constructeurs de se diriger vers l'utilisation des isolants d'origine naturelle. Néanmoins, si ces nouveaux isolants sont neutres du point de vue écologique ils ne donnent pas toujours satisfaction en termes de résistance à l'humidité, de résistance thermique et de longévité. On cherche sans cesse à fabriquer des isolants d'origine naturelle et plus particulièrement végétale répondant au mieux aux contraintes précitées.In real estate, automotive, aerospace, railway and naval construction, thermal and acoustic insulators have long been used. Often these insulators are made of mineral wool or other products that may be harmful during handling and / or use or during destruction. The realization of these disadvantages has pushed the builders to move towards the use of insulation of natural origin. Nevertheless, if these new insulators are ecologically neutral they do not always give satisfaction in terms of resistance to moisture, heat resistance and longevity. We are constantly seeking to manufacture insulators of natural origin and more particularly plant that best meets the aforementioned constraints.
Pour éviter toute interprétation erronée nous indiquons nos définitions de quelques termes techniques.To avoid any misinterpretation we indicate our definitions of some technical terms.
On appelle « fibre » une substance filamenteuse présentant une longueur (ou « taille ») plus de 10 fois supérieure à sa plus grande dimension dans un plan transversal quelconque, les plans transversaux étant les plans coupant la fibre perpendiculairement à la direction de sa longueur.The term "fiber" refers to a filamentary substance having a length (or "size") more than 10 times greater than its largest dimension in any transverse plane, the transverse planes being the planes intersecting the fiber perpendicular to the direction of its length.
La taille moyenne d'un ensemble de fibres est la moyenne arithmétique des longueurs de ces fibres.The average size of a set of fibers is the arithmetic mean of the lengths of these fibers.
On appelle « film » une feuille, généralement souple, d'une épaisseur inférieure à 1 mm.The term "film" refers to a generally flexible sheet having a thickness of less than 1 mm.
On appelle « non tissé » un feutre composé de fibres végétales, synthétiques, ou artificielles d'un poids allant de 15 à 1500 g/m2 et d'une épaisseur allant de 0.5 à 25 mm et réalisée par voie sèche, humide ou papetière.The term "nonwoven" is a felt composed of vegetable, synthetic or artificial fibers with a weight ranging from 15 to 1500 g / m2 and a thickness ranging from 0.5 to 25 mm and produced by the dry, wet or paper process.
On appelle « plaque rigide » une feuille d'une épaisseur supérieure a 5mm.A "rigid plate" is a sheet of thickness greater than 5 mm.
Un objectif de la présente invention est de fournir un matériau isolant répondant, aux nouvelles contraintes de performances thermiques et acoustiques.An object of the present invention is to provide an insulating material meeting the new constraints of thermal and acoustic performance.
A cet effet, l'invention propose un matériau composite isolant thermiquement et acoustiquement.For this purpose, the invention proposes a thermally and acoustically insulating composite material.
Le matériau composite isolant selon l'invention est caractérisé par le fait qu'il comprend au moins une première couche appelée âme, que ladite âme est un nappé comprenant au moins des fibres de jute et de lin et des agents de liage, qu'en pourcentages en masse par rapport à la masse de l'âme, les fibres de jute varient entre 20 et 75%, les fibres de lin entre 20 et 75% et les agents de liage entre 5 et 30%.The insulating composite material according to the invention is characterized in that it comprises at least a first layer called core, that said core is a layer comprising at least jute and linen fibers and binding agents, which in percentages by mass relative to the mass of the core, the jute fibers vary between 20 and 75%, the flax fibers between 20 and 75% and the binding agents between 5 and 30%.
Le déposant est titulaire d'une demande de brevet FR 11 53942 concernant un matériau isolant composite utilisant essentiellement de fibres de lin. Les éléments isolants ainsi obtenus présentent une faible rigidité et leur manipulation et leur utilisation dans certaines applications n'est pas très aisée sans l'adjonction d'un élément plus rigide. En revanche, les fibres de jute à densité équivalente à d'autres fibres végétales, par exemple au lin, permettent d'obtenir des produits plus rigides et une meilleure tenue mécanique. On peut, bien sûr, utiliser les fibres cueillies dans un champ de culture de jute pour fabriquer le produit isolant mais on peut aussi procéder au recyclage de sacs de jute utilisés habituellement pour le stockage de certains produits comme les fèves de café ou de cacao ou autres denrées alimentaires. On procède d'abord au défibrage de sacs de jute et ensuite on recycle les fibres de jute pour fabriquer le matériau isolant. En résumé, les fibres de jute apportent au produit isolant une meilleure rigidité, une meilleure résistance à l'eau et une grande résistance à la décomposition. En plus, le jute est une barrière de protection contre l'attaque microbienne du végétal. En effet, de par sa nature chimique, le jute est une matière extrêmement résistante à divers agents chimiques et à la dégradation biologique et utiliser un isolant comprenant de fibres de jute et de fibres de lin permet de combiner les effets bénéfiques de deux fibres en fonction des applications et du milieu dans lequel les matériaux isolants seront utilisés.The applicant holds a patent application FR 11 53942 concerning a composite insulating material using mainly flax fibers. The insulating elements thus obtained have a low rigidity and their handling and use in some applications is not very easy without the addition of a more rigid element. On the other hand, jute fibers with a density equivalent to other vegetable fibers, for example flax, make it possible to obtain more rigid products and better mechanical strength. You can, of course, use the fibers picked in a field of jute culture to make the insulation product, but you can also recycle jute bags that are usually used for storing certain products such as coffee or cocoa beans. other foodstuffs. Firstly, jute sacks are defibered and then jute fibers are recycled to make the insulating material. In summary, jute fibers provide the insulating product with better rigidity, better water resistance and high resistance to decomposition. In addition, jute is a protective barrier against microbial attack of the plant. Indeed, by its chemical nature, jute is a material extremely resistant to various chemical agents and biological degradation and use an insulation comprising of jute fibers and flax fibers allows to combine the beneficial effects of two fibers in function applications and the environment in which the insulating materials will be used.
Selon une exécution le matériau composite comprend au moins une deuxième couche appelée face, que ladite face est un nappé aiguilleté comprenant en pourcentages en masse par rapport à la masse de la face 5 à 100% de fibres de jute et/ou de chanvre et/ou du lin et/ou d'autres fibres végétales.According to one embodiment, the composite material comprises at least a second layer called a face, said face being a needle-punched web comprising in percentages by weight relative to the mass of the face 5 at 100% of jute and / or hemp fibers and / or flax and / or other vegetable fibers.
L'âme d'un tel matériau qui est un nappé fait de fibres de lin et de jute peut malgré tout dans certains cas présenter une rigidité insuffisante. Cette âme se présente sous la forme d'un rouleau ou d'un panneau. Le fait d'ajouter des faces faites d'un nappé aiguilleté, qui est simplement ou de préférence est doublement aiguilleté, lui permet d'augmenter la rigidité. La composition du matériau permet d'absorber l'humidité ambiante et la restituer lorsque les conditions atmosphériques le permettent. Le fait de travailler avec une âme et une face permet d'améliorer l'isolation acoustique et thermique et supprime tout affaissement dans le temps en pose verticale.The core of such a material which is a web of flax fiber and jute may in some cases still have insufficient rigidity. This soul is in the form of a roll or a panel. The fact of adding faces made of a needle-punched blanket, which is simply or preferably is doubly needled, allows it to increase the rigidity. The composition of the material makes it possible to absorb the ambient humidity and to restore it when the weather conditions allow it. Working with a core and a face improves acoustic and thermal insulation and eliminates sagging over time in vertical installation.
Selon une variante d'exécution, l'âme est située entre deux faces parallèles.According to an alternative embodiment, the core is located between two parallel faces.
Selon une autre exécution la ou les faces comprennent aussi des agents de liage.According to another embodiment the face or faces also comprise binding agents.
Les agents de liage sont choisis parmi des fibres de polyester bicomposant, des fibres en, polyéthylène, des fibres en polypropylène, des fibres thermoliantes à base d'amidon végétal, des poudres thermoplastiques, des résines ou un mélange d'au moins deux de ces agents.The binding agents are selected from two-component polyester fibers, polyethylene fibers, polypropylene fibers, vegetable starch-based thermosizing fibers, thermoplastic powders, resins or a mixture of at least two of these. agents.
Selon une exécution préférée une face au moins est revêtue d'un film et un non tissé comprenant de fibres végétales ou synthétiques ou artificielles.In a preferred embodiment at least one face is coated with a film and a nonwoven comprising vegetable or synthetic or artificial fibers.
Dans le but de répondre à certaines exigences liées à une utilisation spécifique du matériau isolant, une face au moins comprend un agent pulvérisé lui conférant des caractéristiques d'étanchéité à l'eau ou à la vapeur ou l'humidité ou de résistance au feu ou d'accroche.In order to meet certain requirements related to a specific use of the insulating material, at least one face comprises a pulverized agent imparting to it characteristics of water or vapor or moisture impermeability or fire resistance or traction.
Selon une variante d'exécution, une face au moins est revêtue d'un film et/ou d'un non tissé comprenant de fibres végétales ou synthétiques ou artificielles.According to an alternative embodiment, at least one face is coated with a film and / or a nonwoven comprising vegetable or synthetic fibers or artificial fibers.
De préférence les fibres de jute présentent une taille moyenne comprise entre 15 et 100 mm.Preferably, the jute fibers have an average size of between 15 and 100 mm.
L'invention concerne aussi un élément de construction pour bâtiment ou pour véhicule automobile ou ferroviaire ou pour bâtiment naval ou pour aéronef incorporant moins une couche du matériau tel que défini précédemment.The invention also relates to a construction element for a building or for a motor vehicle or railway or for naval building or for aircraft incorporating less a layer of the material as defined above.
L'aiguilleté utilisé pour les faces présente une densité allant de 400g/m2 à 2000g/m2.The needle punch used for the faces has a density ranging from 400g / m2 to 2000g / m2.
