Description

DESCRIPTION DESCRIPTION
TITRE : Procédé de fabrication d'un matériau à base de paille TITLE: Process for manufacturing a straw-based material
[0001] La présente invention se rapporte au domaine de la fabrication de matériaux écologiques, destinés notamment, mais non exclusivement, aux domaines de la construction de bâtiments, de l'industrie, du textile, de l'artisanat. The present invention relates to the field of the manufacture of ecological materials, intended in particular, but not exclusively, for the fields of building construction, industry, textiles, crafts.
[0002] La recherche de matériaux écologiques notamment pour la construction de bâtiments, fait l'objet d'efforts constants de recherche depuis de nombreuses années. [0002] The search for ecological materials, in particular for the construction of buildings, has been the subject of constant research efforts for many years.
[0003] C'est ainsi par exemple que l'on s'est intéressé à la possibilité d'utiliser de la paille pour réaliser l'isolation thermique et phonique de bâtiments notamment à ossature en bois. [0003] Thus, for example, interest has been shown in the possibility of using straw to achieve the thermal and sound insulation of buildings, in particular with a wooden frame.
[0004] Par « paille », on entend, dans le cadre de la présente demande de brevet, la partie de la tige d'une céréale ou d'une graminée comprise entre le chaume (base de la plante) et l'épi (extrémité de la plante). By "straw" is meant, in the context of this patent application, the part of the stem of a cereal or a grass between the stubble (base of the plant) and the ear ( tip of the plant).
[0005] L'utilisation de cette paille est très intéressante tant d'un point de vue écologique que d'un point de vue économique. [0005] The use of this straw is very advantageous both from an ecological point of view and from an economic point of view.
[0006] En effet, sur les 25 millions de tonnes de paille produites annuellement en France, environ 7 millions restent au champ, et une étude de l'INRAE (Institut National de la Recherche pour l'Agriculture, l'Alimentation et l'Environnement) a démontré que sur ces 7 millions, environ 4 millions de tonnes pourraient être récoltées sans dommage agronomique. [0006] Indeed, of the 25 million tons of straw produced annually in France, about 7 million remain in the field, and a study by INRAE (National Research Institute for Agriculture, Food and Environment) demonstrated that of these 7 million, around 4 million tonnes could be harvested without agronomic damage.
[0007] Classiquement, la paille dans le domaine de la construction est compressée en bottes qui, pour respecter les règles en vigueur d'isolation thermique et phonique, doivent présenter une épaisseur de l'ordre de 37 cm, ce qui est très contraignant. [0008] A cela s'ajoute que ces bottes de paille présentent une masse volumique relativement élevée, de l'ordre de 80 à 120 kg par mètre cube, ce qui rend leur manipulation malaisée. [0007] Conventionally, the straw in the field of construction is compressed into bundles which, to comply with the rules in force for thermal and sound insulation, must have a thickness of the order of 37 cm, which is very restrictive. [0008] In addition, these bales of straw have a relatively high density, of the order of 80 to 120 kg per cubic meter, which makes them difficult to handle.
[0009] Pour ces raisons, des travaux ont été menés sur l'utilisation de la laine de paille, c'est-à-dire de fibres résultant du cardage de la paille. [0009] For these reasons, work has been carried out on the use of straw wool, that is to say fibers resulting from the carding of straw.
[0010] Cette opération de cardage consiste à déstructurer mécaniquement les brins de paille, de manière à les transformer en fibres qui, enchevêtrées les unes dans les autres, forment la laine de paille. [0010] This carding operation consists of mechanically destructuring the strands of straw, so as to transform them into fibers which, entangled in each other, form the straw wool.
[0011] Le brevet français FR29900221 illustre un exemple d'utilisation de la laine de paille, à laquelle on incorpore un liant tel que de la fécule de pomme de terre, pour obtenir après séchage un matériau rigide destiné notamment à l'isolation thermique et phonique. French patent FR29900221 illustrates an example of the use of straw wool, in which a binder such as potato starch is incorporated, to obtain, after drying, a rigid material intended in particular for thermal insulation and phonic.
[0012] La laine de paille ayant une densité de l'ordre de 40 kg par mètre cube et d'excellentes propriétés d'isolation thermique et phonique, un matériau selon le brevet français FR29900221 permet donc d'apporter une amélioration sensible par rapport aux bottes de paille de la technique antérieure. Straw wool having a density of the order of 40 kg per cubic meter and excellent thermal and sound insulation properties, a material according to French patent FR29900221 therefore makes it possible to provide a significant improvement compared to prior art straw bales.
[0013] La présente invention a notamment pour but d'améliorer de manière substantielle le procédé décrit dans le brevet FR2900221. The object of the present invention is in particular to substantially improve the process described in patent FR2900221.
[0014] On atteint ce but invention avec un procédé de fabrication d'un matériau à base de paille, dans lequel : a) on carde la paille, b) on récupère d'une part de la laine de paille, et d'autre part de la poudre de paille, c) on mouille au moins ladite poudre de paille, et d) on fait sécher au moins la poudre de paille mouillée. [0015] Dans le cadre de la présente invention, les termes « laine de paille » et « poudre de paille » désignent respectivement les fractions résultant du cardage de la paille présentant typiquement des granulométries respectivement supérieure et inférieure à environ 3 mm. This object of invention is achieved with a process for manufacturing a straw-based material, in which: a) the straw is carded, b) on the one hand straw wool is recovered, and on the other part of the straw powder, c) at least said straw powder is wetted, and d) at least the wet straw powder is dried. In the context of the present invention, the terms "straw wool" and "straw powder" respectively designate the fractions resulting from the carding of straw typically having particle sizes respectively greater and less than about 3 mm.
[0016] La poudre de paille est essentiellement constituée de lignine, qui constitue un bon liant lorsqu'il est mouillé puis séché. [0016] Straw powder consists essentially of lignin, which constitutes a good binder when it is wet and then dried.
[0017] Le procédé selon invention permet donc d'utiliser une fraction de la paille cardée - la poudre de paille - qui peut représenter jusqu'à 50 % en poids de cette paille, alors que cette poudre est inutilisée dans le procédé selon le brevet FR2900221. The process according to the invention therefore makes it possible to use a fraction of the carded straw - the straw powder - which can represent up to 50% by weight of this straw, while this powder is unused in the process according to the patent. FR2900221.
[0018] Lorsqu'on utilise uniquement de la poudre de paille mouillée puis séchée, on peut obtenir des panneaux isolants de revêtement de mur remplissant une fonction analogue à celle des panneaux de plâtre classiques utilisés dans le domaine de la construction. When using only wet and then dried straw powder, it is possible to obtain insulating wall covering panels fulfilling a function similar to that of conventional plasterboard panels used in the field of construction.

[0040] D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit, en référence à la figure annexée, qui illustre : Other characteristics and advantages of the invention will become apparent on reading the following description, with reference to the appended figure, which illustrates:
[Fig. 1] : de manière schématique, les différentes étapes du procédé selon l'invention. [Fig. 1]: schematically, the different steps of the method according to the invention.
[0041] On se reporte à présent à cette figure, sur laquelle on peut voir que la paille récoltée est déversée sur un premier convoyeur 1, afin d'être introduite dans une machine à carder 3. We now refer to this figure, in which we can see that the harvested straw is discharged onto a first conveyor 1, in order to be introduced into a carding machine 3.
[0042] Cette paille peut être choisie dans le groupe défini au paragraphe [0028] ci- dessus. [0042] This straw can be chosen from the group defined in paragraph [0028] above.
[0043] De préférence, cette paille est mouillée avec de l'eau douce et/ou salée et/ou avec de la vapeur d'eau avant son introduction dans la machine à carder 3, et de préférence avec de l'eau chaude : cela permet de réaliser plus facilement le cardage, ainsi que d'éliminer les bactéries. [0043] Preferably, this straw is wetted with fresh and/or salt water and/or with steam before it is introduced into the carding machine 3, and preferably with hot water: this makes carding easier, as well as eliminating bacteria.
[0044] Une telle machine à carder 3, connue en soi, comporte des moyens mécaniques tels que des clous montés sur des bandes circulantes et/ou des disques abrasifs, permettant de déstructurer les brins de paille, et de les transformer en fibres et en poudre, cette dernière étant constituée essentiellement de la lignine de la paille. [0044] Such a carding machine 3, known per se, comprises mechanical means such as nails mounted on circulating belts and/or abrasive discs, making it possible to deconstruct the strands of straw, and to transform them into fibers and powder, the latter consisting essentially of the lignin of the straw.
[0045] La paille ainsi cardée est conduite par un deuxième convoyeur 5 sur un tamis convoyeur 7 tendu entre deux rouleaux 9, 11 dont l'un au moins est moteur. The straw thus carded is driven by a second conveyor 5 onto a conveyor screen 7 stretched between two rollers 9, 11, at least one of which is a motor.
[0046] Ce tamis convoyeur peut comprendre typiquement un tapis de convoyage grillagé, permettant de séparer la laine cardée amenée par le deuxième convoyeur 5 en deux fractions, à savoir une fraction de granulométrie supérieure à 3 mm, restant sur le tamis convoyeur, et une fraction de granulométrie inférieure à 3 mm, passant à travers les mailles de ce tamis convoyeur 7. [0047] Ces fractions de la paille cardée constituent respectivement la laine de paille et la poudre de paille mentionnées précédemment. This conveyor screen may typically comprise a mesh conveyor belt, making it possible to separate the carded wool brought by the second conveyor 5 into two fractions, namely a fraction with a particle size greater than 3 mm, remaining on the conveyor screen, and a fraction of particle size less than 3 mm, passing through the mesh of this conveyor screen 7. These fractions of the carded straw constitute respectively the straw wool and the straw powder mentioned above.
[0048] La poudre de paille tombe sur un troisième tapis convoyeur 13 s'étendant entre les brins supérieur 7a et inférieur 7b du tamis convoyeur 7, et se déplaçant perpendiculairement à celui-ci. The straw powder falls on a third conveyor belt 13 extending between the upper 7a and lower 7b strands of the conveyor screen 7, and moving perpendicular to it.
[0049] Afin de faciliter la séparation de la fraction fine de la paille cardée, des douches d'eau douce ou d'eau salée 15 aspergent la paille cardée qui se trouve sur le brin supérieur 7a du tamis convoyeur 7. In order to facilitate the separation of the fine fraction of the carded straw, showers of fresh water or salt water 15 sprinkle the carded straw which is on the upper strand 7a of the conveyor sieve 7.
[0050] Avantageusement, l'eau qui s'est écoulée sur le tapis convoyeur 13 est récupérée dans un bac situé sous celui-ci (non représenté), puis filtrée afin de récupérer la poudre de paille en suspension. [0050] Advantageously, the water which has flowed over the conveyor belt 13 is recovered in a tank located under the latter (not shown), then filtered in order to recover the straw powder in suspension.
[0051] Selon une première option possible (flèche Fl), la poudre de paille ainsi mouillée, provenant du tapis convoyeur 13 et/ou de la filtration, peut-être conduite directement à l'intérieur d'un mélangeur 17, permettant l'incorporation d'un ou plusieurs liants, d'un ou plusieurs adjuvants, d'un ou plusieurs additifs conformes aux paragraphes [0030], [0033], [0037] ci-dessus, puis le mélange ainsi obtenu peut passer dans un système de moules ou analogues 19 permettant de donner à ce produit la forme souhaitée, conformément au paragraphe [0026] ci-dessus. According to a first possible option (arrow F1), the straw powder thus wetted, coming from the conveyor belt 13 and/or from the filtration, can be led directly inside a mixer 17, allowing the incorporation of one or more binders, one or more adjuvants, one or more additives in accordance with paragraphs [0030], [0033], [0037] above, then the mixture thus obtained can pass through a system of molds or the like 19 making it possible to give this product the desired shape, in accordance with paragraph [0026] above.
[0052] Le produit résultant est conduit par un quatrième convoyeur 20 à l'intérieur d'une zone de séchage 23, comprenant des moyens de production d'air chaud. The resulting product is driven by a fourth conveyor 20 inside a drying zone 23, comprising means for producing hot air.
[0053] Le produit ainsi obtenu peut ensuite subir divers traitements, tel qu'un traitement d'étanchéité 24, conformément au paragraphe [0036] ci-dessus. The product thus obtained can then undergo various treatments, such as a sealing treatment 24, in accordance with paragraph [0036] above.
[0054] Selon une deuxième option possible (flèche F2), la laine de paille mouillée provenant du brin supérieur 7a du tamis convoyeur 7 est elle aussi conduite à l'intérieur du mélangeur 17, où elle rejoint donc la poudre de paille. [0055] Le produit mélangé résultant, éventuellement additionné de liant(s) d'adjuvant(s), d'additif(s) subit ensuite les mêmes étapes de conformation, de séchage, et éventuellement d'étanchéité que celles indiquées ci-dessus. According to a second possible option (arrow F2), the wet straw wool coming from the upper strand 7a of the conveyor sieve 7 is also led inside the mixer 17, where it therefore joins the straw powder. The resulting mixed product, optionally added with binder(s), adjuvant(s), additive(s) then undergoes the same shaping, drying, and optionally sealing steps as those indicated above. .
[0056] La première option susmentionnée permet d'obtenir un matériau isolant typiquement sous forme de plaques, permettant de remplir une fonction d'habillage de mur, analogues aux panneaux de plâtre commercialisés notamment sous la marque Placoplâtre®. The first option mentioned above makes it possible to obtain an insulating material typically in the form of plates, making it possible to fulfill a wall covering function, similar to the plasterboards marketed in particular under the Placoplâtre ® brand.
[0057] La deuxième option susmentionnée permet d'obtenir un matériau isolant typiquement sous forme de blocs, permettant de réaliser des murs et des parois dans la construction de bâtiments notamment à ossature en bois. The aforementioned second option makes it possible to obtain an insulating material typically in the form of blocks, making it possible to produce walls and partitions in the construction of buildings, in particular with a wooden frame.
[0058] Le procédé selon l'invention permet d'utiliser très avantageusement la poudre de paille, qui représente jusqu'à 50 % en poids de la paille cardée, et qui remplit une fonction de liant. The method according to the invention makes it possible to very advantageously use straw powder, which represents up to 50% by weight of the carded straw, and which fulfills a binder function.
[0059] Lorsque cette fonction de liant n'est pas suffisante, on peut ajouter un ou plusieurs liants dont la liste non exhaustive a été fournie au paragraphe [0030] ci-dessus. [0059] When this binder function is not sufficient, one or more binders can be added, the non-exhaustive list of which has been provided in paragraph [0030] above.
[0060] En outre, les adjuvants et additifs proposés permettent de conférer aux panneaux et aux blocs obtenus par le procédé selon l'invention différentes caractéristiques répondant à des cahiers des charges déterminés : résistance au feu, aux nuisibles, à l'humidité, etc. In addition, the adjuvants and additives proposed make it possible to give the panels and blocks obtained by the process according to the invention different characteristics meeting determined specifications: resistance to fire, to pests, to humidity, etc. .
[0061] Ces panneaux et ces blocs peuvent être utilisés seuls, ou bien être rapportés sur d'autres éléments souples ou rigides, comme indiqué au paragraphe [0038] ci-dessus. [0061] These panels and these blocks can be used alone, or else be attached to other flexible or rigid elements, as indicated in paragraph [0038] above.
[0062] Outre l'étape de séchage 23 susmentionnée, des étapes de séchage intermédiaire peuvent aussi être envisagées. In addition to the aforementioned drying step 23, intermediate drying steps can also be considered.
[0063] Le procédé qui vient d'être écrit permet d'obtenir un matériau léger, présentant d'excellentes caractéristiques d'isolation thermique et phonique : un bloc d'un tel matériau d'environ 25 cm d'épaisseur permet d'obtenir d'aussi bons résultats qu'un bloc de paille classique d'épaisseur plus importante. [0064] Ce procédé très écologique permet d'utiliser de manière optimale tous les composants de la paille de céréale ou de graminées, et en particulier la poudre résultant du cardage, très riche en lignine. The process which has just been written makes it possible to obtain a light material, having excellent thermal and sound insulation characteristics: a block of such a material approximately 25 cm thick makes it possible to obtain as good results as a classic thicker block of straw. This very ecological process makes it possible to use all the components of cereal or grass straw in an optimal manner, and in particular the powder resulting from carding, which is very rich in lignin.
[0065] Ce procédé est encore plus avantageux lorsque la paille est issue de l'agriculture biologique, car alors les brins de paille peuvent présenter une longueur nettement supérieure à ceux de l'agriculture classique : typiquement 70 cm contre 25 cm. This process is even more advantageous when the straw comes from organic farming, because then the strands of straw can have a much greater length than those of conventional agriculture: typically 70 cm against 25 cm.
[0066] De plus, ce procédé présente l'avantage de pouvoir être mis en oeuvre par des machines classiques, déjà utilisées pour la fabrication de la laine de verre d'une part et de panneaux de plâtre, d'autre part. In addition, this method has the advantage of being able to be implemented by conventional machines, already used for the manufacture of glass wool on the one hand and of plasterboard, on the other hand.
[0067] On notera toutefois qu'à la différence de la fabrication de laine de verre, le procédé selon invention ne nécessite aucune élévation importante de température, ce qui le rend très peu énergivore. Note however that unlike the manufacture of glass wool, the method according to the invention does not require any significant rise in temperature, which makes it very energy efficient.
[0068] Naturellement, l'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention. Naturally, the invention is described in the foregoing by way of example. It is understood that the person skilled in the art is able to produce different variant embodiments of the invention without departing from the scope of the invention.
