Abstract
Description
Composition durcis sable à deux constituants et application de cette comPosition comme revêtement iso phonique et isothermiaue. Hardened sand composition with two constituents and application of this composition as an isophonic and isothermal coating.
La présente invention concerne une variante de la composition durcissable faisant ltobJet de la demande de brevet français nO 82 01093, du 25 Janvier 1982, au nom de la Demanderesse. The present invention relates to a variant of the curable composition forming the subject of French patent application No. 82 01 093, of January 25, 1982, in the name of the Applicant.
On rappelle que cette composition comprend deux constituants, l'un liquide, l'autre solide à l'état particulaire, que l'on mélange au moment de remploi, le constituant liquide comprenant une résine et un plastifiant en solution ou en suspension dans dé l'eau, tandis que le constituant solide comprend un composé apte à provoquer l'expansion de ladite résine et des charges, et que cette composition est caractérisée en ce que ladite résine et ledit plastifiant sont respectivement un copolymère acry- lique modifié et un plastifiant acrylique, et en ce que le constituant solide contient, en en poids, environ 40 à 55 % de plâtre, environ 8 à 12 % de ciment et, à titre d'agent de compatibilité entre ces deux produits, environ 4 à 6 % d'oxyde de titane. It is recalled that this composition comprises two constituents, one liquid, the other solid in the particulate state, which is mixed at the time of re-use, the liquid constituent comprising a resin and a plasticizer in solution or in suspension in de water, while the solid component comprises a compound capable of causing the expansion of said resin and of the fillers, and that this composition is characterized in that said resin and said plasticizer are respectively a modified acrylic copolymer and a plasticizer acrylic, and in that the solid constituent contains, by weight, about 40 to 55% of plaster, about 8 to 12% of cement and, as a compatibility agent between these two products, about 4 to 6% of titanium oxide.
La présente invention vise à assurer une meilleure cohésion du produit après durcissement, tout en améliorant ses propriétés d'isolation phonique et thermique, sans pour autant majorer son coût. The present invention aims to ensure better cohesion of the product after hardening, while improving its sound and thermal insulation properties, without increasing its cost.
A cet effet, l'invention a pour objet une composition durcissable à deux constituants du type mentionné cidessus, caractérisée en ce que le constituant solide contient de 15 à 30 % de fibres de roche. To this end, the subject of the invention is a curable composition with two constituents of the type mentioned above, characterized in that the solid constituent contains from 15 to 30% of rock fibers.
La Demanderesse a constaté en effet que ltaddition de fibres de roche à la composition antérieure a un triple effet :
- d'une part, ces fibres renforcent la cohésion de la composition durcie
- d'autre part, elles augmentent le volume de cette composition, tout en en diminuant le poids, ce qui se traduit, à masse égale, par une meilleure isolation thermique et phonique t
- enfin, elles permettent d'accroître le volume total de pores de la résine expansée, ce qui a également pour effet d'accroître les qualités d'isolation thermique et phonique de la co;position durcie.The Applicant has indeed found that the addition of rock fibers to the previous composition has a triple effect:
- On the one hand, these fibers reinforce the cohesion of the cured composition
- On the other hand, they increase the volume of this composition, while reducing the weight, which results, for equal mass, in better thermal and sound insulation t
- Finally, they make it possible to increase the total volume of pores of the expanded resin, which also has the effect of increasing the thermal and sound insulation qualities of the hardened position.
Avantageusement, on combinera à cette adjonction de fibres de roche l'addition de silicate d'aluminium en poudre et de silicate de calcium en poudre. Les cristaux de silicate d'aluminium s'entrecroisent, en effet, avec les fibres de roche, au cours du durcissement de la composition, en accroissant ainsi la cohésion de l'ensemble et en favorisant la formation de micropores dans la résine. Le silicate de calcium vise essentiellement à allèges la composition durcie. Advantageously, the addition of rock fibers will be combined with the addition of powdered aluminum silicate and powdered calcium silicate. The aluminum silicate crystals, in fact, intersect with the rock fibers, during the hardening of the composition, thereby increasing the cohesion of the whole and promoting the formation of micropores in the resin. The calcium silicate essentially aims to lighten the hardened composition.
En général, la quantité de silicate de calcium sera de l'ordre de 2 %, rapportés au poids total du constituant solide, et le silicate d'aluminium représentera 5 % de la masse de silicate de calcium. In general, the amount of calcium silicate will be of the order of 2%, based on the total weight of the solid component, and the aluminum silicate will represent 5% of the mass of calcium silicate.
A titre d'exemple, le constituant solide d'une aompc- sition destinée à être appliquée à l'extérieur d'un bâtiment sous la forma d'une couche de 5 ma d'épaisseur, aura la coNposition suivante (en kg). By way of example, the solid constituent of a composition intended to be applied to the exterior of a building in the form of a layer 5 m thick, will have the following composition (in kg).
- plâtre : 347,
- vermiculite : 283,
- ciment : 347,
- mélange B (voir comoosition
ci-après ) : 85,
- fibre de roche commercialisée
sous l'appellation DOSSOLAN : 159 à 321,
- silicate de calcium s 26,
- silicate d'alumine : 1,3
Pour une application à l'intérieur d'un batiment, où les propriétés isophoniques recherchées sont plus importantes que les propriétés isothermiques et où l'on emploiera donc plus de plâtre que dans le cas précédent, la composition en kg du constituant solide, pour une application sous la forme d'une couche de 5 mm d'épaisseur pourra être la suivante
- platre : 682,
- vermiculite : 283,
- ciment : 155,
- mélange B
(voir composition ci-après) : 85,
- fibre de roche commercia
lisée sous l'appelation
DOSSOLAN : 181 à 362,
- silicate de calcium : 30,
- silicate d'alumine s 1,5.- plaster: 347,
- vermiculite: 283,
- cement: 347,
- mixture B (see composition
below): 85,
- rock fiber sold
under the name DOSSOLAN: 159 to 321,
- calcium silicate s 26,
- alumina silicate: 1.3
For an application inside a building, where the desired isophonic properties are more important than the isothermal properties and where therefore more plaster will be used than in the previous case, the composition in kg of the solid constituent, for a application in the form of a layer 5 mm thick could be as follows
- plaster: 682,
- vermiculite: 283,
- cement: 155,
- mixture B
(see composition below): 85,
- commercial rock fiber
read under the name
DOSSOLAN: 181 to 362,
- calcium silicate: 30,
- alumina silicate s 1.5.
Le mélange B est un prémélange de produits solides qui a lui-même la composition suivante (en kg)
- oxyde de titane : 40,
- fibres de cellulose . o, 520,
- ester cellulosique (agissant
comme retardateur de prise) : 20.Mix B is a premix of solid products which itself has the following composition (in kg)
- titanium oxide: 40,
- cellulose fibers. o, 520,
- cellulosic ester (acting
as setting retarder): 20.
Le constituant liquide, dans les deux cas, pourra avoir la composition suivante s
- résine commercialisée par la
Société Henkel sous la dési-
gnation AC 330 (versatate de
vinyl acryl s 40 1,
- butyl glycol (coalescent) : 12 kg,
- eau : 65 1. The liquid constituent, in both cases, may have the following composition:
- resin sold by
Henkel Company under the
gnation AC 330 (versatate of
vinyl acryl s 40 1,
- butyl glycol (coalescent): 12 kg,
- water: 65 1.
in mélange liquide/solide sera effectué dans le rapport 1,4 pour 1, soit 11 kg de solide en poudre pour 15 kg de liquide. in a liquid / solid mixture will be carried out in the ratio 1.4 for 1, ie 11 kg of solid powder for 15 kg of liquid.
Les essais au feu effectués avec la composition conforme à l'invention, après durcissement, avec une couche de 5 mm d'épaisseur, montrent que la composition résiste jusqu'à 9000C sans séparation de ses différents composants. Le retard au feu à 6600C (essai normalisé sur une poudre chargée à 16 kg/mm2) est de 35 mn. Fire tests carried out with the composition according to the invention, after hardening, with a layer of 5 mm thick, show that the composition withstands up to 9000C without separation of its various components. The fire retardance at 6600C (standard test on a powder loaded at 16 kg / mm2) is 35 min.
L'invention apporte donc un perfectionnement appré ciable aux compositions durcissables à deux constituants, l'un liquide, l'autre solide, de la technique antérieure. The invention therefore provides an appreciable improvement to the curable compositions with two constituents, one liquid, the other solid, of the prior art.
