Abstract

The heat and sound insulation mortar to be casted, comprises minimum granules of cork (15-80 vol.%), plant fibers (8-30 vol.%), casein (1-12 vol.%) and clay (3-19 vol.%). An independent claim is included for a process for fabricating a mortar.

Description

-1- La présente invention concerne le procédé pour la fabrication d'un mortier d'isolation acoustique et thermique naturel et respirant, â base de granulat de liège et fibres végétales et nouveaux produits obtenus. Jusqu'alors les enduits isolants contenant des granules de liège et/ou des fibres végétales, connus pour leurs pouvoirs d'isolants thermiques et acoustiques, contiennent soit une grande quantité de liant et /ou charges minérales ou bien contiennent dans leur composition des résines et/ou des plastifiants de synthèses, migrés cela leur application sur surface verticale (mur) ne peut excéder une épaisseur de 70 mm par couche sans quoi il est nécessaire d'utiliser un coffrage. The present invention relates to the process for the manufacture of a natural and breathable acoustic and thermal insulation mortar, based on cork granulate and vegetable fibers and new products obtained. Until now insulating coatings containing cork granules and / or vegetable fibers, known for their thermal and acoustic insulating powers, contain either a large amount of binder and / or mineral fillers or contain in their composition resins and or synthetic plasticizers, migrated that their application on vertical surface (wall) can not exceed a thickness of 70 mm per layer without which it is necessary to use a formwork.

L'inconvénient majeur lorsqu'on utilise en Viande quantité des liants hydrauliques et/ou charges minérales réside dans l'accroissement de la densité du mortier, et par conséquent amoindrit les qualités thermiques du dit mortier. dans le cas des enduits contenant des produits de synthèses, les inconvénients sont de deux types: En premier lieu il bloquent l'échange gazeux entre l'intérieur et l'extérieur de la construction ce qui a pour effet de diminuer les performances thermiques, mais aussi dans le cas du bâti ancien d'empêcher l'évacuation par la partie aérienne de la construction des remontées capillaires et ainsi de créer une rétention d'humidité dans les murs, qui est préjudiciable, tant pour le bâti que pour les habitant (développement de bactéries pathogènes). En second lieu, la gestion en fin de vie de matériaux composites contenant une part de matériaux synthétique devra suivre la filière d'élimination des matériaux synthétiques qui est très onéreuse. La présente invention par la combinaison des produits naturels qu'elle utilisent permet de gommer les inconvénients des procédés actuellement utilisé et augmentent de manière conséquente les performances thermiques de ce type de produit, sans remettre en cause les méthodes de mise en oeuvre utilisées. Les nouveaux produits issus du procédé de fabrication sont composés: - De granules de liège expansé ou non, d'un spectre de granulométrie étudier en fonction de 30 l'application farci, qui apportent au mortier des caractéristiques d'absorption acoustique très intéressantes. - De fibres végétales (type linL chanvre, orge. bois. ou tout autres paille végétale) 2942795 -?- permettant de fibrer le mortier et donc absorber les variations dimensionnelles du mortier sans créer de fissures et, qui évite ainsi l'adjonction de charges minérales en Bande quantité, ce qui allège considérablement le mélange final et en accroit les performances thermiques. 5 - De sel de bore connu pour ses qualités putti-fongiques protégeant ainsi les fibres végétales. - De caseïne et d'argile qui créent une émulsion légère. liante et très enrobante qui permet de diminuer la quantité de liant hydraulique. d'augmenter l'épaisseur des couches sans compromettre la tenue dans le temps. 10 -Le carbonate de calcium hydraulique ou non permet une prise relativement rapide et minéralise le tout pour protéger le mortier dans le temps des intempéries. - et éventuellement une charge minérale. L'ensemble de ces produits étant perméables à l'échange gazeux la combinaison résultante l'est par voie de conséquence.The major disadvantage when using Mande quantity of hydraulic binders and / or mineral fillers lies in increasing the density of the mortar, and therefore reduces the thermal qualities of said mortar. in the case of coatings containing synthetic products, the disadvantages are of two types: first, they block the gas exchange between the inside and the outside of the construction, which has the effect of reducing the thermal performance, but also in the case of the old building to prevent the evacuation by the aerial part of the construction of the capillaries and thus to create a retention of moisture in the walls, which is detrimental, both for the building and for the inhabitants (development pathogenic bacteria). Secondly, the end-of-life management of composite materials containing a part of synthetic materials will have to follow the waste disposal route for synthetic materials, which is very expensive. The present invention by the combination of the natural products that it uses makes it possible to erase the disadvantages of the processes currently used and consequently increases the thermal performance of this type of product, without calling into question the methods of implementation used. The new products resulting from the manufacturing process are composed of: - granules of cork, expanded or not, a spectrum of particle size to be studied according to the stuffed application, which provide the mortar with very interesting acoustic absorption characteristics. - vegetable fibers (such as hemp, barley, wood, or any other vegetable straw) 2942795 -? - allowing the mortar to be fiber-reinforced and thus absorbing dimensional variations of the mortar without creating cracks and thus avoiding the addition of fillers Mineral in quantity, which considerably reduces the final mix and increases the thermal performance. 5 - Boron salt known for its putti-fungal qualities thus protecting plant fibers. - Casein and clay that create a light emulsion. binder and very coating which reduces the amount of hydraulic binder. to increase the thickness of the layers without compromising the behavior over time. 10 -The hydraulic calcium carbonate or not allows a relatively fast setting and mineralized all to protect the mortar in weather weather. - and possibly a mineral filler. Since all these products are permeable to gas exchange, the resulting combination is consequently.

15 Les composants étant renouvelables, sans danger pour la santé et facilement éliminable par compostage en fin de vie, en font une invention à très faible empreinte écologique. L'invention a en plus l'avantage de pouvoir être férmulée dans les appareils courants ou bien manuellement suivant des mode opératoires simple sans avoir besoin de recourir à une main d'oeuvre spécialisée. Elle a en outre l'avantage d'être appliquer avec tous les moyen 20 mécaniques et manuels disponibles et répandus (machine à projeter y compris) Le présent mortier. en fiiisant varier les proportions et pour le liège, l'étendue de la granulométrie, peut être appliquer en couche de 2nun à 12(hnm en extérieur, et en intérieur pour les partie verticales et en intérieur pour la réalisation de chapes légères et isolante. Le mode de réalisation de l'invention détaillé ci-après ne saurait en aucun cas, 25 limiter de si peu que ce soit la portée de ladite invention. 2942795 -3- DESIGNATION DES COMPOSANTS PROPORTION: exprimée en pourcentages volumiques Argile de 3 à 19 % Caséine del à 12 % Fibres végétale (lin, ou chanvre, ou tout autre paille de 8 à 30 % végétale) Granulat de liège expansés ou non de 15 à 80 % Chaux aérienne ou hydrauliques de 0 à 25 % Sel de Bore ou BORAX de 0 à 4 % Pigments de 0 à 30 % Méthyle de cellulose de 0 à 5 % Quartz de 0 à 25°io Silice de0à25°lo Poudre de marbre de 0 à 25 % Savon de0à5% Conservateur de 0 à 3 % Les composants sont mélangés à l'aide d'un malaxeur conventionnel. soit ils seront mélangé à sec et seront ensuite mis en sacs, et utilisés tel quel sur le chantier 5 en ajoutant l'eau nécessaire et en mélangeant environ 10 minutes. soit ils seront mélangés a sec pendant 10 minutes environ, on y ajoutera l'eau nécessaire ainsi qu'un conservateur .
