Description
Revêtement chauffant et procédé de fabrication de ce revêtement
On a déjà proposé des chaussées chauffantes présentant une série de tubulures disposées sous le tapis de roulement, et t dans lesquelles circule soit de la vapeur, soit de l'eau chaude: la construction de ce genre de chaussée n'a cependant jamais pu être effectuée sur une très grande échelle, d'une part, à cause des travaux de génie civil très. importants qu'elle nécessite et du coût très élevé de I'installation, et, d'autre part, parce que leur exploitation est loin d'etre rentable. On comprend en outre facilement qu'un tel genre de chaussée ne peut de toute manière faire l'objet que d'une utilisation limitée, et qu'elle ne convient guère, par exemple, pour les autoroutes de très grande longueur.
L'invention, objet du présent brevet, se propose précisément d'obvier à oes inconvénients, et a trait, à cet effet, à un revêtement chauffant, notamment pour la couverture de chaussées ou de parois, qui se caractérise par le fait qu'il est formé d'au moins une plaque constituée par une masse de résine synthétique durcie par polymérisation, à l'intérieur de laquelle est noyé au moins un corps de chauffe électrique.
L'invention a également trait à un procédé de fabrication, de ce revêtement, caractérisé par le fait que l'on applique au moins une première couche de résine synthétique liquide et durcissable à l'air sur le support devant recevoir le revêtement, que l'on place ledit corps de chauffe électrique sur cette première couche de résine, que l'on recouvre ce corps de chauffe par au moins une seconde couche de résine synthétique liquide et durcissable à l'air, et enfin que l'on laisse durcir la résine.
Des formes d'exécution du revêtement selon l'invention et des mises en oeuvre du procédé de fabrication de ce revêtement sont décrites ci-après, à titre d'exemple.
Ce procédé se met en oeuvre en faisant usage de résines synthétiques molles ou fluides durcissant par polymérisation, par exemple par polyaddition.
On peut par exemple utiliser une résine à deux composants, un émail et un ingrédient durcisseur: à titre d'exemple, l'émail. peut être constitué par un polyamide tel que celui vendu sous le nom de vers amide et l'ingrédient par une résine époxy.
La résine obtenue par mélange de ces deux composants offre une très grande dureté et est particulièrv ment résistante aux chocs, à l'abrasion, à l'eau, aux acides dilués, organiques et inorganiques, ainsi qu'à la plupart des dissolvants. Cette résine synthétique peut être additionnée de particules abrasives, notam ment t de silicium ou de corindon, faisant office de matériau de remplissage, tout en améliorant les con ditions d'adhérence pour les pneumatiques des véhicules circulant sur le revêtement.
Ainsi qu'on le verra par la suite, il est particulièrement avantageux de pouvoir par exemple améliorer la conductibilité thermique de tout ou partie de la masse de résine constituant le revêtement, en particulier de la couche supérieure de résine, comprise entre le corps de chauffe et la surface de roulement de ce revêtement: à cet effet, on incorpore à la masse de résine des particules métalliques, bonnes conductrices de la ehaleur, par exemple de la poudre d'aluminium, de cuivre ou du corindon.
On peut également améliorer les caractéristiques de résistance de la résine utilisée en additionnant à cette résine des fibres de verre.
Le corps de chauffe peut être e formé par un ou plusieurs fils métalliques, placés sur un tissu de verre, ou incorporé à ce tissu, dans sa trame, dans sa chaîne, ou encore dans les deux avec interposition d'isolant aux points de croisement des différents fils.
La fabrication du revêtement décrit peut s'effectuer en usine sous forme de plaques de dimensions relativement t réduites, facilement transportables à pied d'oeuvre et qui sont réunies ensuite les uns aux autres, mécaniquement et électriquement; il est bien entendu également possible de fabriquer ce revêtement à pied d'oeuvre, auquel cas on pourra par exemple recouvrir une surface déterminée par un revêtement formant une plaque unique.
Dans un n cas comme dans l'autre, on commencera par recouvrir un support, lorsqu'il s'agit de plaques fabriquées en usine, ou la surface à revêtir, lorsqu'il s'agit d'une fabrication à pied d'oeuvre, d'une première couche de résine synthétique que l'on recouvre d'un tissu de fibres de verre sur lequel on dispose les résistances de chauffe lorsqu'elles ne sont pas déjà englobées dans ce tissu, puis on recouvrira l'ensemble tissu de fibres de verre-résistances de chauffe par une autre couche de résine synthétique qui formera la piste de roulement lorsque par exempie le revêtement est destiné à des chaussées de routes, de trottoirs, de ponts ou d'aérodromes. De manière générale, les résistances de chauffe seront disposées à peu près au milieu de l'épaisseur totale du revêtement fabriqué.
On laisse ensuite sécher l'ensemble jusqu'à durcissement complet, lequel peut avoir lieu en 24 ou ou 48 heures selon les cas : il est également possible d'accélérer ce durcissement, par exemple, en alimentant les résistances électriques par du courant.
Le revêtement chauffant qui vient d'être décrit est très efficace et permet d'éliminer toute formation de glace ou dépôt de neige dans les endroits où il est utilisé; il est t également très utile dans le cas des pistes d'aérodromes parce qu'il permet de neutraliser dans une très grande mesure la. formation de brouillard.
Ce revêtement peut également être utilisé comme moyen de chauffage de locaux par le sol, les plafonds ou les parois, ainsi que pour la fabrication de piscines chauffantes.
On signalera enfin, qu'il est également t possible de l'utiliser pour la fabrication de cuves chauffantes ou de corps de chauffe plongeants pour l'industrie chimique.
Heating coating and method of manufacturing this coating
Heated pavements have already been proposed having a series of tubes arranged under the treadmill, and in which circulates either steam or hot water: the construction of this type of pavement has however never been possible. carried out on a very large scale, on the one hand, because of the very civil works. important that it requires and the very high cost of the installation, and, on the other hand, because their operation is far from being profitable. It is also easily understood that such a type of roadway can in any case only be the subject of limited use, and that it is hardly suitable, for example, for very long highways.
The invention, object of the present patent, proposes precisely to obviate these drawbacks, and relates, to this end, to a heating coating, in particular for the covering of roads or walls, which is characterized by the fact that it is formed of at least one plate consisting of a mass of synthetic resin hardened by polymerization, inside which is embedded at least one electric heating body.
The invention also relates to a method of manufacturing this coating, characterized in that at least a first layer of liquid and air-curable synthetic resin is applied to the support to receive the coating, which l 'said electric heating body is placed on this first layer of resin, which this heating body is covered with at least a second layer of liquid synthetic resin which can be hardened in air, and finally which is allowed to harden. resin.
Embodiments of the coating according to the invention and implementations of the process for manufacturing this coating are described below, by way of example.
This process is carried out by making use of soft or fluid synthetic resins which harden by polymerization, for example by polyaddition.
One can for example use a resin with two components, an enamel and a hardening ingredient: for example, enamel. may consist of a polyamide such as that sold under the name of worm amide and the ingredient of an epoxy resin.
The resin obtained by mixing these two components offers a very high hardness and is particularly resistant to impact, abrasion, water, dilute acids, organic and inorganic, as well as most solvents. This synthetic resin may be supplemented with abrasive particles, in particular silicon or corundum, acting as a filling material, while improving the conditions of adhesion for the tires of vehicles running on the pavement.
As will be seen below, it is particularly advantageous to be able, for example, to be able to improve the thermal conductivity of all or part of the mass of resin constituting the coating, in particular of the upper layer of resin, between the heating body. and the rolling surface of this coating: for this purpose, metallic particles, which are good conductors of heat, for example aluminum powder, copper or corundum, are incorporated into the mass of resin.
The strength characteristics of the resin used can also be improved by adding glass fibers to this resin.
The heating body can be formed by one or more metallic threads, placed on a glass fabric, or incorporated into this fabric, in its weft, in its warp, or even in both with the interposition of insulation at the crossing points. of the different threads.
The manufacture of the coating described can be carried out in the factory in the form of plates of relatively small dimensions, easily transportable on the job and which are then joined together, mechanically and electrically; it is of course also possible to manufacture this coating on the job, in which case it is possible, for example, to cover a determined surface with a coating forming a single plate.
In either case, we will begin by covering a support, in the case of plates manufactured in the factory, or the surface to be coated, in the case of on-the-job production. , with a first layer of synthetic resin which is covered with a fabric of glass fibers on which the heating resistors are placed when they are not already included in this fabric, then the entire fabric will be covered with glass fibers-heating resistors by another layer of synthetic resin which will form the runway when, for example, the coating is intended for roads, sidewalks, bridges or airfields. Generally, the heating resistors will be arranged approximately in the middle of the total thickness of the coating manufactured.
The assembly is then left to dry until complete hardening, which can take place in 24 or 48 hours depending on the case: it is also possible to accelerate this hardening, for example, by supplying the electrical resistors with current.
The heating coating which has just been described is very effective and makes it possible to eliminate any formation of ice or deposit of snow in the places where it is used; it is also very useful in the case of aerodrome runways because it allows to neutralize to a very great extent the. fog formation.
This coating can also be used as a means of heating premises by the floor, ceilings or walls, as well as for the manufacture of heated swimming pools.
Finally, it should be pointed out that it is also possible to use it for the manufacture of heating tanks or immersion heating bodies for the chemical industry.
