Peinture chauffante améliorée. Enhanced heat painting.
La présente invention concerne le domaine du chauffage. The present invention relates to the field of heating.
Elle concerne plus particulièrement une peinture chauffante améliorée It relates more particularly to an improved heating paint
On connaît du document FR2 802 761 un dispositif de chauffage comprenant du graphite amorphe, et permettant d'atteindre une température de 100°C. Document FR2 802 761 discloses a heating device comprising amorphous graphite and making it possible to reach a temperature of 100 ° C.
Le document W09626984 divulgue une matière fluide ou pâteuse électriquement conductrice destinée à couvrir une surface, et convenant notamment pour le chauffage par rayonnement. Cette matière comprend un liant et des charges conductrices comportant des oxydes doubles. Elle permet dans certains cas d'atteindre une température légèrement supérieure à l OO 'C. The document WO9626984 discloses a fluid or pasty electrically conductive material intended to cover a surface, and which is particularly suitable for radiant heating. This material comprises a binder and conductive fillers comprising double oxides. It allows in some cases to reach a temperature slightly above 100 ° C.
Néanmoins dans de nombreuses applications, il est souhaitable d'atteindre des températures bien supérieures, dépassant 500 °C, en particulier pour des éléments radiants pouvant atteindre ces températures. However, in many applications, it is desirable to achieve much higher temperatures, exceeding 500 ° C, especially for radiant elements that can reach these temperatures.
La présente invention a pour but de pallier au moins en partie à ces inconvénients. A cet effet elle propose une peinture chauffante destinée à être déposée sur un substrat en vue d'y appliquer une tension électrique de sorte à obtenir une augmentation de sa température. Cette peinture chauffante est particulière en ce qu'elle comprend une résine acrylique en phase aqueuse et du graphite, dans laquelle ladite résine acrylique représente entre 40 et 90% en poids de ladite peinture chauffante. The present invention aims to overcome at least some of these disadvantages. For this purpose it proposes a heating paint intended to be deposited on a substrate in order to apply a voltage to it so as to obtain an increase in its temperature. This heating paint is particular in that it comprises an acrylic resin in aqueous phase and graphite, wherein said acrylic resin represents between 40 and 90% by weight of said heating paint.
Grâce à la combinaison du graphite et de la résine acrylique en phase aqueuse dans les proportions indiquées, la peinture selon l'invention résiste à des températures très largement supérieures à 100°C, dans certains cas dépassant 500 'C sans se dénaturer, tout en permettant une fluidité suffisante d'une part, et non excessive d'autre part. Thanks to the combination of graphite and acrylic resin in the aqueous phase in the proportions indicated, the paint according to the invention withstands temperatures much greater than 100 ° C., in some cases exceeding 500 ° C. without being denatured, while allowing a sufficient fluidity on the one hand, and not excessive on the other hand.
Selon d'autres caractéristiques According to other characteristics
- ledit graphite peut être un graphite diamagnétique, ce qui améliore les performances de vitesse de montée en température de ladite peinture chauffante, said graphite may be a diamagnetic graphite, which improves the temperature rise rate performance of said heating paint,
- ledit graphite peut représenter entre 10 et 60% en poids de ladite peinture chauffante, permettant une conductivité suffisante et non excessive, La présente invention concerne encore un élément chauffant comportant une couche de peinture chauffante selon l'invention. Cet élément chauffant est particulier en ce que l'épaisseur de ladite couche est supérieure à un demi millimètre. said graphite may represent between 10 and 60% by weight of said heating paint, allowing a sufficient and not excessive conductivity, The present invention also relates to a heating element comprising a heating paint layer according to the invention. This heating element is particular in that the thickness of said layer is greater than half a millimeter.
Selon d'autres caractéristiques : According to other characteristics:
- ledit élément chauffant peut comporter deux électrodes configurées pour appliquer ladite tension à ladite couche, et lesdites électrodes être disposées dans l'épaisseur de ladite couche ; on observe en effet que la performance en termes de vitesse de montée en température en est améliorée, said heating element may comprise two electrodes configured to apply said voltage to said layer, and said electrodes to be arranged in the thickness of said layer; it can be seen that the performance in terms of rate of rise in temperature is improved,
- ledit élément chauffant peut comporter deux couches d'une telle peinture chauffante. said heating element may comprise two layers of such a heating paint.
La présente invention concerne enfin un procédé d'application d'une peinture selon l'invention. Ce procédé est particulier en ce qu'il comprend les étapes suivantes, dans cet ordre : The present invention finally relates to a method of applying a paint according to the invention. This method is particular in that it comprises the following steps, in this order:
- application d'une première couche - application of a first layer
- pose des électrodes sur ladite première couche - laying electrodes on said first layer
- application d'une deuxième couche de sorte à recouvrir lesdites électrodes. L'avantage apporté par la présente invention réside principalement en ce qu'elle propose une peinture chauffante qu'on peut mettre en œuvre à des températures bien supérieures à celles utilisables avec les peintures chauffantes de l'état de la technique. Par ailleurs elle est particulièrement simple à mettre en œuvre, et n'a pas d'effet dangereux pour l'homme ni à titre chimique, ni à titre électrique en 12V. applying a second layer so as to cover said electrodes. The advantage of the present invention lies mainly in that it provides a heating paint that can be implemented at temperatures much higher than those used with the heating paints of the state of the art. Moreover it is particularly simple to implement, and has no dangerous effect for humans either chemically or electrically in 12V.
La présente invention sera mieux comprise à la lecture de la description détaillée qui suit faite en référence aux figures annexées dans lesquelles : The present invention will be better understood on reading the following detailed description with reference to the appended figures in which:
la figure 1 est une vue en coupe d'un élément chauffant selon l'invention, FIG. 1 is a sectional view of a heating element according to the invention,
- la figure 2 est une vue de face de l'élément chauffant de la fig. 1 FIG. 2 is a front view of the heating element of FIG. 1
Comme on peut le voir sur la fig. 1 du dessin ci-joint, l'élément chauffant 1 selon l'invention comporte de préférence une première couche 2 de peinture chauffante, une deuxième couche 3 de peinture chauffante, et deux électrodes 4 et 5 disposées sensiblement au milieu de l'épaisseur constituée des deux couches 2, 3 de peinture chauffante. Il est disposé sur un substrat 6. Des essais ont été effectués en disposant les électrodes 4, 5 sous, ou sur l'élément chauffant 1 . Avec une épaisseur de peinture chauffante de 500μηι, 250μηι pour chacune des couches 2, 3, une longueur d'électrode de 60 cm et un écartement des électrodes de 5 cm, on obtient avec une tension appliquée de 10V une puissance consommée de 89W quand les électrodes sont placées sous l'élément, de 58W quand les électrodes sont placées sur l'élément chauffant 1 , et 136W quand les électrodes sont placées dans l'épaisseur de l'élément chauffant 1 , comme illustré à la fig. 1 . Il est donc avantageux de disposer les électrodes 4, 5 dans l'épaisseur de la couche de l'élément chauffant 1 , ladite couche étant dans cet exemple constituée de deux couches 2, 3 superposées. On peut de préférence disposer les électrodes 4, 5 entre ces deux couches superposées 2 et 3. As can be seen in fig. 1 of the attached drawing, the heating element 1 according to the invention preferably comprises a first layer 2 of heating paint, a second layer 3 of heating paint, and two electrodes 4 and 5 disposed substantially in the middle of the thickness constituted two layers 2, 3 of heating paint. It is arranged on a substrate 6. Tests were carried out by placing the electrodes 4, 5 under, or on the heating element 1. With a heating paint thickness of 500μηι, 250μηι for each of the layers 2, 3, an electrode length of 60 cm and a spacing of the electrodes of 5 cm, a power consumption of 89 W is obtained with an applied voltage of 10 V when the The electrodes are placed under the element, 58W when the electrodes are placed on the heating element 1, and 136W when the electrodes are placed in the thickness of the heating element 1, as illustrated in FIG. 1. It is therefore advantageous to arrange the electrodes 4, 5 in the thickness of the layer of the heating element 1, said layer being in this example constituted of two superposed layers 2, 3. The electrodes 4, 5 can preferably be arranged between these two superposed layers 2 and 3.
Typiquement chacune des couches 2 et 3 peut présenter une épaisseur de 250μηι. En effet des couches épaisses permettent de bien meilleures puissances. Dans l'exemple ci-dessus, avec des couches réduites à "Ι ΟΟμηι chacune, la puissance chute à 50W au lieu des 136W. Typically each of the layers 2 and 3 may have a thickness of 250μηι. Indeed thick layers allow much better powers. In the example above, with layers reduced to " Ι ΟΟμηι each, the power drops to 50W instead of 136W.
La distance entre les électrodes est également un paramètre important déterminant la puissance consommée : quand on augmente cette distance de 5cm dans l'exemple ci-dessus, à 16cm, la puissance chute de 136W à 47W. Pour augmenter la puissance, on peut alors augmenter la tension appliquée. En effet en appliquant une tension de 10V alternatifs et 3A d'intensité, on obtient une puissance de 30W, et on atteint une température de 85 'Ό après vingt minutes de chauffage, puis cette température se stabilise. Si on applique une tension de 220V alternatifs et 10A d'intensité, on obtient une puissance de 2200W, on atteint une température de 250 °C en moins de trois minutes, et plus de 500 'Ό en moins de cinq minutes. The distance between the electrodes is also an important parameter determining the power consumed: when we increase this distance of 5cm in the example above, at 16cm, the power drops from 136W to 47W. To increase the power, it is then possible to increase the applied voltage. Indeed by applying a voltage of 10V AC and 3A intensity, we obtain a power of 30W, and reached a temperature of 85 'Ό after twenty minutes of heating, then this temperature stabilizes. If we apply a voltage of 220V AC and 10A of intensity, we obtain a power of 2200W, we reach a temperature of 250 ° C in less than three minutes, and more than 500 'Ό in less than five minutes.
D'une manière générale, une tension alternative donne de meilleures performances qu'une tension continue, en termes de vitesse de montée en température. In general, an AC voltage gives better performance than a DC voltage, in terms of rate of rise in temperature.
On a également observé au cours des essais qu'une tension continue appliquée dans la surface de la peinture chauffante est sensiblement identique qu'on soit proche des fils d'alimentation 7 (voir fig. 2), ou qu'on s'en éloigne, mais croissante en allant de l'électrode négative 4 vers l'électrode positive 5. Par ailleurs la température est maximale sensiblement à mi-distance entre les fils d'alimentation 7 et l'autre extrémité de l'élément chauffant 1 , et très faible à l'extérieur de la zone comprise entre les deux électrodes, ceci s'expliquant probablement par de la conduction thermique du substrat. It has also been observed during the tests that a DC voltage applied in the surface of the heating paint is substantially identical whether it is close to the supply wires 7 (see Fig. 2), or away from it. but increasing by going from the negative electrode 4 to the positive electrode 5. By Moreover the temperature is maximum substantially halfway between the supply son 7 and the other end of the heating element 1, and very low outside the zone between the two electrodes, this probably being explained. by thermal conduction of the substrate.
Une composition préférée de peinture chauffante contient : A preferred composition of heating paint contains:
- 43,27% de résine vinyle versatate, à 50% d'extrait sec - 43.27% versatate vinyl resin, 50% solids
- 4,81 % de débullant, à 40% d'extrait sec - 4,81% of debullant, with 40% of dry extract
- 33,65% de graphite diamagnétique, à 100% d'extrait sec - 33.65% diamagnetic graphite, 100% dry extract
- 0,2% de biocide, à 100% d'extrait sec - 0.2% biocide, 100% dry extract
- 18,07% d'eau - 18.07% water
La styrène acrylique est également une résine qui convient. Acrylic styrene is also a suitable resin.
On peut augmenter la part de graphite dans cette composition, et réduire la part de résine notamment pour utilisation en tension plus basse. We can increase the proportion of graphite in this composition, and reduce the share of resin especially for use in lower voltage.
On peut également diminuer la part de graphite et augmenter la part de résine en phase aqueuse, notamment pour utilisation en tension plus élevée. It is also possible to reduce the proportion of graphite and increase the proportion of resin in the aqueous phase, especially for use in higher tension.
Le graphite peut être mis en œuvre sous forme de pigments avec des concentrations en poids allant de 7 à 70%. On peut utiliser du graphite simple, par exemple tel qu'on peut le trouver sous la marque Timrex®, référence K25. Néanmoins les performances sont meilleures avec un graphite diamagnétique, comme la référence SFG75 du même fabricant. La montée en température est bien plus rapide avec un graphite diamagnétique. Dans le cadre de la présente demande, il faut comprendre sous l'expression « graphite diamagnétique » un graphite aux propriétés diamagnétiques améliorées, en général liées à la pureté améliorée. Graphite can be used in the form of pigments with weight concentrations ranging from 7 to 70%. It is possible to use simple graphite, for example such as can be found under the trademark Timrex®, reference K25. Nevertheless the performances are better with a diamagnetic graphite, like reference SFG75 of the same manufacturer. The rise in temperature is much faster with a diamagnetic graphite. In the context of the present application, the term "diamagnetic graphite" should be understood to mean a graphite with improved diamagnetic properties, generally related to the improved purity.
Le choix des résines phase aqueuse, qu'elles soient hydro-diluables ou hydro- solubles, permet d'une part une mise en œuvre à l'eau, et d'autre part une tenue en température bien meilleure que des résines solvantées. En effet la peinture selon l'invention dans laquelle une telle résine en phase aqueuse est associée à du graphite, a résisté, selon les essais effectués, à une température de 540 °C. L'essai a été interrompu à cette température par crainte de détérioration du substrat 6 ; la peinture elle-même résiste probablement à des températures encore supérieures. Une telle résistance à chaud est très surprenante, les peintures chauffantes de l'état de la technique étant limitées à un peu plus de 100 <€. The choice of aqueous phase resins, whether hydro-dilutable or water-soluble, allows on the one hand an implementation with water, and on the other hand a much better temperature resistance than solvent resins. In fact, the paint according to the invention in which such a resin in aqueous phase is associated with graphite, has withstood, according to the tests carried out, at a temperature of 540 ° C. The test was interrupted at this temperature for fear of deterioration of the substrate 6; the painting itself is probably resistant to even higher temperatures. Such a hot resistance is very surprising, the heating paints of the state of the art being limited to a little more than 100 < €.
On s'aperçoit que les consommations électriques sont faibles en regard des températures atteintes, et permettent, avec quelques dizaines de watts d'être efficaces en chauffe, en adaptant cette consommation à l'utilité recherchée. We realize that the electricity consumption is low compared to the temperatures reached, and allow, with a few tens of watts to be effective in heating, adapting this consumption to the desired utility.
La peinture chauffante selon l'invention est une peinture toute aussi simple d'utilisation que n'importe quelle autre peinture de bâtiment. The heating paint according to the invention is a paint as easy to use as any other building paint.
Une, ou de préférence deux couches 2, 3 posées avec des moyens conventionnels tels que pinceau, rouleau, pistolet, suffisent à produire un effet thermique suffisamment significatif. La peinture chauffante selon l'invention est déposée sur un substrat 6 isolant électriquement, équipé de deux électrodes 4, 5 longitudinales et parallèles en matériau conducteur, cuivre, argent ou autre, elles-mêmes reliées à une alimentation à travers un système de régulation. One, or preferably two layers 2, 3 laid with conventional means such as brush, roller, gun, are sufficient to produce a sufficiently significant thermal effect. The heating paint according to the invention is deposited on an electrically insulating substrate 6, equipped with two longitudinal and parallel electrodes 4, 5 of conductive material, copper, silver or other, themselves connected to a supply through a control system.
La peinture selon l'invention peut être utilisée par couches de quelques dizaines de microns, comme n'importe quelle peinture. En formulation plus pâteuse, elle peut être utilisée en enduit de quelques millimètres d'épaisseur. The paint according to the invention can be used in layers of a few tens of microns, like any other paint. In more pasty formulation, it can be used in plaster of a few millimeters thick.
La peinture selon l'invention ainsi déposée sur un substrat 6 peut transmettre à celui-ci la chaleur produite pour la restituer dans le temps, soit en rayonnement, soit en convection, ou alors directement chauffer par rayonnement l'ambiance ou l'objet exposé. The paint according to the invention thus deposited on a substrate 6 can transmit thereto the heat produced to restore it over time, either in radiation or in convection, or can then directly heat the atmosphere or the object by radiation. .
Un grand nombre de fonctionnalités de chauffe sont envisageables avec l'élément chauffant selon l'invention : A large number of heating functions can be envisaged with the heating element according to the invention:
- le chauffage domestique, notamment bâtiment à basse consommation, à basse température pour les sols chauffants ; à 100W de consommation, on peut maintenir une chauffe en surface de 35^ pour un mètre carré ; à température intermédiaires, de 40 à 90 ^, on peut l'appliquer sur des éléments chauffants de type radiateur, avec des consommations de 50 à 400W ; il est aussi possible de l'appliquer à des chauffe-eau ; - domestic heating, especially low-energy buildings, at low temperatures for heated floors; at 100W of consumption, one can maintain a surface heating of 35 ^ per one square meter; at intermediate temperatures, from 40 to 90 ° C., it can be applied to radiator-type heating elements, with consumptions of 50 to 400 W; it is also possible to apply it to water heaters;

The heating elements according to the invention generate significant savings in terms of energy consumption. They are adaptable to various forms, to the most varied substrates, and its implementation does not require expensive technology.
