Produit incombustible remplaçant le bois et les matières similaires, et son procédé de fabrication,
Cette invention est relative à un produit incombustible et à son procédé de fabrication, produit destiné à être uti- lise en remplacement du bois et des matières similaires, no- tamment dans les installations et les appareils électriques, où son incombustibilité évite tout danger d'incendie par court-circuit et où ses qualités d'isolant présentent des avantages considérables. D'autre part, ce produit est impu- trescible, de sorte que sa durée est très grande, même lors- qu'il est soumis à l'humidité ou à l'action des intempéries Il est inattaquable par les acides et par les substances cor- rosives. Il peut être travaillé avec la même facilité que le bois.
On sait que la solution de silicate de soude, contenant un excès de silice, a la propriété de se combiner lentement à froid aux silicates des roches basiques du genre amphibole et, en particulier, à l'amiante et au kaolin, pour donner des si-
<Desc/Clms Page number 2>
lioates très durs, inaltérables à l'air et à l'eau. Il en est de même avec les verres à base de chaux et avec les porcelai- nes.
On sait d'autre part que le silicate de potasse, conte- nant un excès de silice, forme avec la chaux à froid un sili- cate double qui devient très dur après plusieurs jours.
Le procédé conforme à cette invention consiste essentiel- lement :
1 - à juxtaposer ces deux actions,
2 - à remplacer en tout ou en partie le verre et le kao- lin par toutes les variétés de mica, en particulier le mica moscovite.
3 - à accélérer le durcissement par l'action d'une tem- pérature modérée ne dépassant pas 200 .
4 - à faciliter l'évaporation de l'eau venant des cou- ches profondes par l'adjonction d'une petite quantité de sciure de bois ne dépassant pas 10 % du mélange total, qui empêche le durcissement trop rapide de la surface, avant que toute l'eau ne soit évaporée.
5 - à diminuer la dureté et la piorosité, par l'adjone- tion de petites quantités de gélatine industrielle, sous for- me de colle de Givet ou toute autre colle.
Le mica, broyé en poudre fine, est mélangé à l'amiante dans des proportions variant depuis 1/3 jusqu'à 2/3 du mica.
On y ajoute de la chaux vive en proportions variables avec les proportions d'amiante, le poids de chaux augmentant quand celui d'amiante diminue, de telle façon que le poids de chaux ne dépasse pas 20 % du poids total. On y ajoute la sciure de bois, passée au tamis, puis la colle. Quand le mélange est très homogène, on y ajoute le silioate de soude à 50 % de silice en excès, à raison de 1,3 à 1,5 fois le poids de mica, et 0,5 fois le poids d'amiante, puis le silicate de potasse correspondant à la chaux. Le mélange, bien malaxé est moulé
<Desc/Clms Page number 3>
sous une légère pression, puis séché quelques heures à une température ne dépassant pas 200 .
La sciure de bois empêche les boureoufflures dans la masse. Si le produit est destiné à séjourner dans des locaux très humides, on ne met pas de sciure, et le séchage se fait d'abord à une température inférieure à 110 portée graduel- lement à 200 .
Le produit ainsi obtenu est d'un prix de revient peu éle- vé. Ses applications sont multiples, notamment partout où. une installation ou une construction doit être à l'abri du feu et de l'humidité. On peut l'utiliser avantageusement pour former des parois isolantes ou protectrices, des revêtements, couver- tures, etc...,
Sous forme de moulures, il sera employé dans les instal- lationsd'.éclairage et de force électrique.
Il est bien entendu que le procédé de fabrication décrit plus haut est susceptible de recevoir des modifications tant comme matières que comme proportions. On pourra au besoin ajouter d'autres substances et utiliser des substances équi- valentes à celles indiquées,

Cette invention concerne :
A/.- Un procédé de fabrication d'un produit remplaçant: le bois et les matières similaires et caractérisé essentiel- lement par ce fait qu'un mélange de mica pulvérisé, d'amiante, de chaux vive et dans certains cas, de sciure de bois et de colle, est additionné de silicate de soude, puis de silicate de potasse, ce mélange, bien malaxé, étant finalement moulé sous une légère pression, puis séché à une température conve. nable .

Non-combustible product replacing wood and similar materials, and its manufacturing process,
This invention relates to an incombustible product and to its manufacturing process, a product intended to be used as a replacement for wood and similar materials, in particular in electrical installations and appliances, where its incombustibility prevents any danger of fire. short-circuit fire and where its insulating qualities have considerable advantages. On the other hand, this product is rot-proof, so that its duration is very long, even when it is subjected to humidity or to the action of bad weather. It is unassailable by acids and by substances cor- rosives. It can be worked with the same ease as wood.
It is known that the sodium silicate solution, containing an excess of silica, has the property of combining slowly in the cold with the silicates of basic rocks of the amphibole genus and, in particular, with asbestos and kaolin, to give so -
<Desc / Clms Page number 2>
Very hard lioates, unalterable to air and water. It is the same with lime-based glasses and porcelain.
It is also known that potassium silicate, containing an excess of silica, forms with cold lime a double silicate which becomes very hard after several days.
The process according to this invention consists essentially of:
1 - to juxtapose these two actions,
2 - to replace all or part of glass and kao- lin by all the varieties of mica, in particular Muscovite mica.
3 - to accelerate the hardening by the action of a moderate temperature not exceeding 200.
4 - to facilitate the evaporation of water coming from the deep layers by the addition of a small quantity of sawdust not exceeding 10% of the total mixture, which prevents too rapid hardening of the surface, before that all the water is not evaporated.
5 - to reduce the hardness and the piorosity, by the addition of small quantities of industrial gelatin, in the form of Givet glue or any other glue.
Mica, ground into a fine powder, is mixed with asbestos in proportions varying from 1/3 to 2/3 of the mica.
Quicklime is added to it in variable proportions with the proportions of asbestos, the weight of lime increasing when that of asbestos decreases, so that the weight of lime does not exceed 20% of the total weight. We add the sawdust, passed through a sieve, then the glue. When the mixture is very homogeneous, there is added sodium silioate containing 50% excess silica, at a rate of 1.3 to 1.5 times the weight of mica, and 0.5 times the weight of asbestos, then the silicate of potash corresponding to the lime. The mixture, well kneaded, is molded
<Desc / Clms Page number 3>
under slight pressure, then dried for a few hours at a temperature not exceeding 200.
The sawdust prevents blisters in the mass. If the product is intended to stay in very humid rooms, no sawdust is used, and the drying is carried out first at a temperature below 110, gradually raised to 200.
The product thus obtained has a low cost price. Its applications are multiple, especially everywhere. an installation or construction must be protected from fire and humidity. It can be used advantageously to form insulating or protective walls, coatings, covers, etc.,
In the form of moldings, it will be used in lighting and electrical power installations.
Of course, the manufacturing process described above is susceptible to modifications both in terms of materials and in proportions. You can add other substances if necessary and use substances equivalent to those indicated,
ABSTRACT
This invention relates to:
A /.- A process for the manufacture of a substitute product: wood and similar materials and characterized mainly by the fact that a mixture of pulverized mica, asbestos, quicklime and in certain cases, sawdust of wood and glue, is added sodium silicate, then silicate of potash, this mixture, well kneaded, being finally molded under a slight pressure, then dried at a suitable temperature. nable.
