Description
La présente invention a pour objet un nouvel isolant thermique et/ou phonique élaboré à partir de glumes et/ou de glumelles de céréales, plus particulièrement de Maïs, obtenues par la valorisation des déchets de récolte et de conditionnement des grains. En ce qui concerne le Maïs, le terme bractée , qui regroupe les termes de glume et de glumelle, est plus approprié. II s'agit des pièces florales en forme de feuille faisant partie de l'inflorescence et pouvant ressembler à des pétales, notamment par leurs coloris. Chez le Maïs elles sont généralement de couleur cuivrée. Elles se situent à la base de chaque grain de Maïs dans leur partie en liaison avec la rafle. Dans le milieu agricole on les désigne à tort par les termes de follicule ou son. The subject of the present invention is a new thermal and / or phonic insulator made from glumes and / or lemmas of cereals, more particularly corn, obtained by the recovery of harvesting and grain conditioning waste. With regard to corn, the term bract, which includes the terms glume and lemma, is more appropriate. These are leaf-shaped floral parts that are part of the inflorescence and can resemble petals, especially by their colors. In corn they are usually copper colored. They are at the base of each corn kernel in their part in connection with the roundup. In the agricultural environment they are wrongly referred to by the terms of follicle or sound.
Le monde a prit conscience de l'importance capitale d'isoler les bâtiments afin de réduire l'impact sur l'environnement. II sait aussi que, pour ce faire et pour sa propre santé, il doit privilégier l'utilisation des matériaux d'origine naturelle et nécessitant l'énergie globale la plus faible pour leur production. Si la part des isolants d'origine naturelle s'est nettement renforcée ces 10 dernières années, 15 il est nécessaire de toujours faire évoluer ce domaine afin de remédier aux différents inconvénients suivants : ^ L'utilisation de surface agricole normalement destinée aux besoins vitaux. ^ Les faibles volumes disponibles. ^ L'éloignement entre les sites de production et les lieux d'utilisation. 20 ^ L'énergie globale nécessaire à leur production. ^ L'indisponibilité d'isolant d'origine naturelle en vrac. ^ Le décompactage des isolants à utiliser en vrac, notamment en épandage manuel. On a déjà proposé d'utiliser la plante de Maïs pour l'isolation (FR2532584 et W003099932), mais tous utilisent la rafle broyée. Ces techniques ont le désavantage de nécessiter une 25 énergie considérable pour le broyage et les conductivités thermiques obtenues sont loin d'être intéressantes. L'isolant objet de la présente invention a pour but d'apporter une réponse à l'ensemble de ces inconvénients. / Il ne mobilise aucune surface agricole nouvelle puisqu'il est issu des déchets de 30 récolte et de conditionnement des grains. Son élaboration permettra, de plus, une valorisation de tous les autres composants du déchet. / Il est disponible en quantité relativement importante dans toutes les régions où le Maïs est cultivé (1 200 m3 pour 100 000 tonnes de grain). / Sa transformation ne demande pas d'énergie importante. 35 / Il sera disponible en vrac mais également sous d'autres formes (plaque, rouleau, etc.) et pourra être combiné avec tout autre matériau de façon à former une nouvelle matière isolante. / Il a la capacité de recouvrer son volume initial lors du décompactage et il résiste au tassement. 2941472 -2- La matière de base, de laquelle seront extraits les composants principaux de l'isolant objet de la présente invention, est un déchet agricole provenant de diverses sources, et est généralement générée lors des opérations de battage, de séchage, de tri ou de toute autre opération de manipulation des céréales. 5 Pour le Maïs, elle est notamment générée lors des périodes de récolte des grains en Septembre/Octobre ainsi qu'à la sortie des cribs en Avril/Mai, et également lors des opérations de transformation dans les industries du grain ou de la rafle. En fait. elle pourrait provenir de tout travail réalisé sur la plante de Maïs. La proportion de bractées dans la matière de base est directement liée au degré d'humidité relative des grains ainsi 10 qu'aux conditions de battage. Pour des questions de commodité, et dans un premier temps, l'approvisionnement se fera auprès des installations de séchage, de stockage et transformation du grain. Cette matière de base est composée, de façon aléatoire et en proportion fluctuante, de toutes les parties de la plante de Maïs telle que morceaux de rafle, morceaux de tiges, parties de feuille ou de spathe, soies, bractées, morceaux de grain ainsi que de farine de grain. Elle peut être sèche ou humide. La matière première sera séchée pour être ramené à une humidité relative de 13 à 14%, puis tamisée pour en séparer les farines, et enfin triée afin de selectionner les éléments ayant une masse volumique inférieure à 100 Kg/m3 et plus particulièrement entre 30 et 60 Kg /m3. Ces opérations de transformation pourront être augmentées ou diminuées en nombre et pourront être réalisées dans un ordre différent. L'isolant, produit résultant de ces traitements, est principalement composé de bractées mais on pourra également y trouver des soies ou stigmates, des fibres extraites de la tige, des parties de spathe, de feuille et de moelle de la rafle ainsi que d'autre partie de la plante de Maïs. Il sera ensuite traité par pulvérisation d'un sel de Bore lui conférant une résistance aux rongeurs, aux insectes, à la moisissure et au feu. L'isolant sera disponible en vrac et sous toute autre forme telle que plaque, rouleau, etc. L'invention consiste donc à utiliser des glumes et/ou des glumelles de céréales pour former un isolant thermique et/ou phonique. La composition ainsi obtenue, objet de l'invention, peut présenter d'autres caractéristiques complémentaires telles que : Etre constituée de bractées de Maïs représentant de 10% à 90%, en poids ou en volume, du produit final. comprendre, en outre, en complément des bractées de Maïs, les soies ou stigmates et/ou les fibres extrait de la tige et/ou les spathes et/ou les feuilles et/ou la moelle de la rafle et/ou toute autre partie de la plante de Maïs, et ce dans des proportions de 10% à 90% en poids ou en volume. Etre constituée d'éléments ayant une humidité relative maximum de 13% ou 14% par rapport au poids sec. The world has realized the critical importance of isolating buildings to reduce the impact on the environment. He also knows that, in order to do this and for his own health, he must favor the use of materials of natural origin and requiring the lowest overall energy for their production. Although the share of natural insulators has increased significantly in the last 10 years, it is necessary to always develop this field in order to remedy the following disadvantages: The use of agricultural surface normally intended for vital needs. ^ Low volumes available. ^ The distance between production sites and places of use. 20 ^ The overall energy needed for their production. ^ The unavailability of insulation of natural origin in bulk. ^ Decompaction of insulation to be used in bulk, especially in manual spreading. It has been proposed to use the corn plant for insulation (FR2532584 and W003099932), but all use the milled crop. These techniques have the disadvantage of requiring considerable energy for grinding and the thermal conductivities obtained are far from being of interest. The object of the present invention aims to provide an answer to all of these disadvantages. It mobilizes no new agricultural area since it comes from harvesting and grain conditioning waste. Its development will, in addition, a valuation of all other components of the waste. / It is available in relatively large quantities in all areas where corn is grown (1,200 m3 per 100,000 tonnes of grain). / Its transformation does not require significant energy. 35 / It will be available in bulk but also in other forms (plate, roll, etc.) and can be combined with any other material to form a new insulating material. / It has the capacity to recover its initial volume during the decompacting and it resists the settlement. The base material, from which the main components of the insulation object of the present invention will be extracted, is an agricultural waste product from various sources, and is generally generated during threshing, drying and sorting operations. or any other grain handling operation. 5 For maize, it is notably generated during grain harvesting periods in September / October as well as at the end of cribs in April / May, and also during processing operations in the grain or stalk industry. In fact. it could come from any work done on the corn plant. The proportion of bracts in the base material is directly related to the relative humidity of the grains as well as the threshing conditions. For convenience, and initially, the supply will be with grain drying, storage and processing facilities. This base material is composed, randomly and in fluctuating proportion, of all parts of the corn plant such as pieces of stalk, pieces of stems, parts of leaf or spathe, bristles, bracts, pieces of grain as well as of grain flour. It can be dry or wet. The raw material will be dried to be brought to a relative humidity of 13 to 14%, then sieved to separate the flours, and finally sorted to select the elements having a density of less than 100 Kg / m3 and more particularly between 30 and 60 Kg / m3. These transformation operations may be increased or decreased in number and may be performed in a different order. The insulation resulting from these treatments is mainly composed of bracts but may also be found bristles or stigmas, fibers extracted from the stem, parts of spathe, leaf and marrow of the stalk as well as other part of the corn plant. It will then be sprayed with a boron salt giving it resistance to rodents, insects, mildew and fire. The insulation will be available in bulk and in any other form such as plate, roll, etc. The invention therefore consists in using glumes and / or glumellae of cereals to form a thermal and / or phonic insulator. The composition thus obtained, which is the subject of the invention, may have other additional characteristics such as: Being composed of corn bracts representing from 10% to 90%, by weight or by volume, of the final product. further comprising, in addition to the corn bracts, the bristles or stigmas and / or the fibers extracted from the stem and / or the husks and / or the leaves and / or the marrow of the stalk and / or any other part of the corn plant, and this in proportions of 10% to 90% by weight or by volume. Be composed of elements having a maximum relative humidity of 13% or 14% relative to the dry weight.
Etre constituée d'éléments ayant une masse volumique inférieure à 100 Kg/m3. 2941472 -3- - Etre additionnée d'un composant lui conférant une résistance aux rongeurs et/ou aux insectes et/ou à la moisissure et/ou au feu. L'exemple suivant est destiné à illustrer l'invention, étant bien entendu qu'il ne présente vis-à-vis d'elle aucun caractère limitatif.Be composed of elements having a density of less than 100 Kg / m3. 2941472 -3- - Add a component that gives resistance to rodents and / or insects and / or mildew and / or fire. The following example is intended to illustrate the invention, it being understood that it has no limiting character vis-à-vis it.
5 Exemple de réalisation: Pour le Maïs, et pour un exemple parmi d'autres, la matière première récupérée est passée sur un premier tamis de maille de 4mm x 4mm. Au dessus, les éléments de masse volumique faible sont aspirés et réintroduits au produit de dessous. Le produit de dessous est séché dans un four continu pour être ramené à une humidité relative maximum de 13% 10 ou 14% par rapport au poids sec. II passe sur un second tamis de maille de 1,5 mm x 1,5 mm. Au dessus, par centrifugation et aspiration, on sélectionne les composants ayant une masse volumique inférieure à 100 Kg/m3. Suivant la matière première de base, La sélection ainsi obtenue est une composition isolante constituée, en volume ou en poids, de 10% à 90% de bractées et en complément de 5% à 90% de soies, de 0% à 90% de fibre de 15 tige, de 5% à 90% de spathe, de 0% à 90% de feuille, de 0% à 90% de moelle de rafle et de 0% à 90% de toute autre partie de la plante. Elle reçoit un traitement lui conférant une résistance aux rongeurs, aux insectes, à la moisissure et au feu, par pulvérisation de sel de Bore à raison de 0,1% à 2,4% en poids. Le produit ainsi obtenu est ensuite conditionné en vue de sa commercialisation comme 20 produit isolant en vrac. Embodiment Example: For corn, and for one example among others, the recovered raw material is passed over a first 4mm x 4mm mesh sieve. Above, the low density elements are sucked and reintroduced to the bottom product. The bottom product is dried in a continuous oven to be brought to a maximum relative humidity of 13% or 14% by dry weight. It passes on a second sieve of mesh of 1.5 mm x 1.5 mm. Above, by centrifugation and suction, the components having a density of less than 100 Kg / m3 are selected. According to the basic raw material, the selection thus obtained is an insulating composition consisting, in volume or by weight, of 10% to 90% of bracts and in addition of 5% to 90% of bristles, from 0% to 90% of bristles. stalk fiber, 5% to 90% spathe, 0% to 90% leaf, 0% to 90% stalk and 0% to 90% of any other part of the plant. It receives a treatment conferring resistance to rodents, insects, mildew and fire, by spraying boron salt at a rate of 0.1% to 2.4% by weight. The product thus obtained is then packaged for marketing as a bulk insulating product.
