    Acoustically and thermally insulating composite material
    The present invention relates to an acoustically and thermally insulating composite material.
    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.
    To avoid any misinterpretation we indicate our definitions of some technical terms.
    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.
    The average size of a set of fibers is the arithmetic mean of the lengths of these fibers.
    The term "film" refers to a generally flexible sheet having a thickness of less than 1 mm.
    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.
    A "rigid plate" is a sheet of thickness greater than 5 mm.
    An object of the present invention is to provide an insulating material meeting the new constraints of thermal and acoustic performance.
    For this purpose, the invention proposes a thermally and acoustically insulating composite material.
    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%.
    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.
    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.
    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.
    According to an alternative embodiment, the core is located between two parallel faces.
    According to another embodiment the face or faces also comprise binding 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.
    In a preferred embodiment at least one face is coated with a film and a nonwoven comprising vegetable or synthetic or artificial fibers.
    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.
    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.
    Preferably, the jute fibers have an average size of between 15 and 100 mm.
    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.
