Description

La présente invention se rapporte à une composition combustible produisant une flamme de couleur. Une telle composition peut être utilisée en particulier dans un dispositif d'éclairage du type à mèche immergée lorsqu'elle est liquide ou dans un dispositif du type bougie ou bougie-gel lorsqu'elle est solide.The present invention relates to a combustible composition producing a flame of color. Such a composition can be used in particular in a lighting device of the submerged wick type when it is liquid or in a device of the candle or gel candle type when it is solid.

Plus particulièrement, l'invention concerne une telle composition liquide ou solide pour utilisation dans un dispositif d'éclairage à usage décoratif, religieux ou autre, produisant une flamme colorée. Un dispositif d'éclairage comprenant un réservoir contenant un liquide combustible, une mèche partiellement immergée dans ledit liquide et éventuellement un porte mèche est connu depuis l'antiquité.More particularly, the invention relates to such a liquid or solid composition for use in a decorative lighting device, religious or otherwise, producing a flame colorful. A lighting device comprising a reservoir containing a combustible liquid, a wick partially immersed in said liquid and optionally a wick is known since antiquity.

Plus récemment, afin de satisfaire des besoins d'ordre décoratif, religieux ou autre, on s'est attaché à produire des solutions combustibles qui fournissent, lors de leur combustion, une flamme colorée. De nombreux efforts en ce sens ont été livrés sans toutefois qu'un résultat totalement satisfaisant du point de vue de la combustion, de la sécurité, de l'économie, de la conservation (stabilité) et/ou de la coloration n'ait été obtenu. Pour s'en convaincre, il suffit d'observer le marché qui ne dispose pas encore de telles solutions combustibles liquides ou solides ni de dispositifs d'éclairage satisfaisants.More recently, in order to satisfy decorative, religious or other needs, we have attached to produce combustible solutions that provide, when burning, a flame colorful. Many efforts in this direction have been delivered without however a result totally satisfactory from the point of view of combustion, safety, economy, conservation (Stability) and / or staining was obtained. To be convinced of this, one need only observe the market which does not yet have such liquid or solid fuel solutions or devices satisfactory lighting.

La demanderesse s'est donc attachée à mettre au point une composition combustible pour un dispositif d'éclairage du type précité comprenant une composition combustible produisant une flamme de couleur lors de sa combustion. Elle a plus particulièrement cherché, dans un but décoratif, de telles compositions qui sont incolores ou faiblement colorées en l'absence de combustion.The applicant has therefore endeavored to develop a fuel composition for a lighting device of the aforementioned type comprising a fuel composition producing a color flame during its combustion. In particular, she sought for a purpose such compositions which are colorless or weakly colored in the absence of combustion.

Une composition combustible produisant une flamme de couleur par oxydo-ionisation thermique doit comprendre au moins un composant combustible et un composant colorigène. Si cette composition doit se présenter sous la forme d'un liquide, il est conventionnel d'utiliser comme composant combustible des alcools primaires ou secondaires, des polyols ou autres molécules oxygénées possédant un nombre restreint d'atome de carbone (voir à ce sujet le brevet US 3.726.731). La combustion du mélange s'effectue en deux temps: le composant combustible liquide passe d'abord en phase gazeuse sous l'effet de la chaleur dégagée, puis les gaz ainsi obtenus se combinent avec l'oxygène atmosphérique et entrent en combustion. La chaleur dégagée par ladite combustion a pour effet, d'une part de permettre la vaporisation d'une quantité supplémentaire de composant combustible alimentant ainsi la flamme et, d'autre part, d'ioniser le composant colorigène.A combustible composition producing a color flame by oxidation ionization The thermal system shall include at least one combustible component and one color component. Yes this composition must be in the form of a liquid, it is conventional to use as combustible component of primary or secondary alcohols, polyols or other molecules with a small number of carbon atoms (see US patent 3726731). The combustion of the mixture is carried out in two stages: the combustible component liquid passes first into the gas phase under the effect of the heat released, then the gases and obtained combine with atmospheric oxygen and enter into combustion. The heat released by said combustion has the effect, on the one hand, to allow the vaporization of a quantity additional fuel component fueling the flame and, on the other hand, ionizing the colorigenic component.

Dans le cas d'une composition liquide, il est également essentiel que le composant colorigène soit réparti dans le composant combustible de manière homogène en sorte que la coloration de la flamme soit constante durant la combustion de toute la composition. En général toutefois, les agents colorigènes se présentent sous forme de solides peu solubles dans les liquides constituant le composant combustible. On a bien suggéré de former une suspension, une émulsion ou autre, mais jamais, l'homogénéité idéale n'a été observée.In the case of a liquid composition, it is also essential that the component coloring material is distributed evenly throughout the fuel component so that the staining of the flame is constant during the combustion of the entire composition. In general however, the coloring agents are in the form of solids that are poorly soluble in liquids constituting the combustible component. It has been suggested to form a suspension, an emulsion or other, but never, the ideal homogeneity was observed.

D'autres facteurs pris en compte pour l'élaboration des compositions conformes à la présente invention sont les suivants: le mélange doit être suffisamment inflammable (point d'éclair suffisamment bas) tout en respectant les limites imposées par la sécurité. Les normes de sécurités imposent en effet un point d'éclair qui ne peut être inférieur à 55°C. En outre, pour des raisons de conservation et de sécurité, le mélange ne doit pas être trop volatil (pression de vapeur saturante faible à température ambiante). De plus, il doit avoir une bonne capacité de diffusion dans la mèche en sorte que celle-ci ne soit pas consommée trop rapidement. Enfin, le mélange ne peut comprendre de substances considérées comme toxiques ou étant classées comme telles par la communauté européenne telles que le méthanol en quantité supérieure ou égale à 10% en poids, voir même nocives, comme l'éthylène glycol en quantité supérieure ou égale à 25% en poids.Other factors taken into account for the development of the compositions according to the The present invention is as follows: the mixture must be sufficiently flammable (flash point low enough) while respecting the limits imposed by security. Security standards impose a flashpoint that can not be less than 55 ° C. In addition, for reasons of conservation and safety, the mixture should not be too volatile (saturation vapor pressure low at room temperature). Moreover, it must have a good diffusion capacity in the wick so that it is not consumed too quickly. Finally, the mixture can not substances that are considered toxic or are classified as such by the European Community such as methanol in a quantity greater than or equal to 10% by weight, even harmful, such as ethylene glycol in an amount greater than or equal to 25% by weight.

Pour répondre à ces contraintes, les inventeurs ont déterminé que la composition devait contenir les constituants suivants dans des proportions pondérales assez précises. :

  • de 78 à 98 % en poids d'un mélange de propylène glycol et d'eau comprenant de 2,5 à 12 % en poids d'eau;
  • jusqu'à 9 % en poids de butanol;
  • jusqu'à 4 % en poids d'un agent colorigène choisi parmi les sels de sodium et/ou de lithium des acides formique et acétique; et
  • jusqu'à 9 % en poids d'acide borique en tant qu'agent colorigène
avec la réserve qu'au moins un des deux agents colorigènes est présent.To meet these constraints, the inventors have determined that the composition should contain the following constituents in fairly precise weight proportions. :
  • from 78 to 98% by weight of a mixture of propylene glycol and water comprising from 2.5 to 12% by weight of water;
  • up to 9% by weight of butanol;
  • up to 4% by weight of a colorigen selected from sodium and / or lithium salts of formic and acetic acids; and
  • up to 9% by weight of boric acid as coloring agent
with the proviso that at least one of the two coloring agents is present.

D'autres additifs visant à changer les propriétés rhéologiques du mélanges peuvent bien évidemment être ajoutés pour autant que les proportions indiquées ci-avant sont respectées. Par exemple, on peut ajouter une huile (par exemple, on peut ajouter une huile de type huile de bio-masse) ou de la paraffine afin de fournir une composition huileuse (pour utilisation dans une lampe à huile par exemple). Afin de fournir une composition solide (pour utilisation en tant que bougie par exemple), on peut durcir la composition au moyen d'une composition d'un copolymère bloc de type SBS (styrène-butadiène-styrène) et d'un isocyanate mis en oeuvre à raison de 1 à 5 % en poids.
On pourrait également gélifier ces compositions par exemple au moyen d'une composition d'un copolymère tribloc de type SE/BS (styrène-éthylène/butylène-styrène) et d'un isocyanate pour obtenir un gel de type "élastomère" ou au moyen d'un carbopol pour un gel classique.Other additives intended to change the rheological properties of the mixture may of course be added provided that the proportions indicated above are respected. For example, an oil (e.g., a bio-mass oil type) or paraffin can be added to provide an oily composition (for use in an oil lamp for example). In order to provide a solid composition (for use as a candle for example), the composition can be cured by means of a composition of an SBS (styrene-butadiene-styrene) type block copolymer and an isocyanate 1 to 5% by weight.
These compositions could also be gelled for example by means of a composition of a triblock copolymer of SE / BS type (styrene-ethylene / butylene-styrene) and an isocyanate to obtain an "elastomer" type gel or by means of a carbopol for a classic gel.

L'utilisation du propylène glycol dans des compositions combustibles a déjà été mentionnée dans l'état de la technique comme par exemple dans le brevet US 3.790.332, mais, en raison de son hygroscopie très élevée a été rejetée. A ce jour, on ne trouve pas sur le marché de compositions comprenant du propylène glycol.The use of propylene glycol in combustible compositions has already been mentioned in the state of the art, such as in US Pat. No. 3,790,332, but because of its very high hygroscopy was rejected. To date, we do not find on the market of compositions comprising propylene glycol.

D'une manière surprenante, la demanderesse a pu mettre en évidence que cette hygroscopie élevée du propylène glycol ne constituait pas un problème et pouvait, au contraire et pour autant que la composition comprenne certains constituants particuliers dans des rapports pondéraux bien précis, contribuer à améliorer les propriétés de la composition.Surprisingly, the plaintiff was able to highlight that this high hygroscopy of propylene glycol was not a problem and could, on the contrary, as long as the composition includes certain particular constituents in reports precise weightings, help to improve the properties of the composition.

L'eau présente dans la composition combustible liquide selon l'invention a pour effet principal d'abaisser la température de combustion. Les inventeurs ont remarqué que ceci n'est pas un inconvénient si certains constituants particuliers sont présents dans des rapports pondéraux bien précis. Cette eau peut être déjà présente dans le propylène glycol en sorte qu'il n'est nullement nécessaire de recourir à l'achat de produit anhydre particulièrement cher. L'eau peut également provenir, pour tout ou partie, de l'eau d'hydratation de l'agent colorigène. Enfin, on peut également rajouter directement de l'eau à la composition. Dès lors que la composition comprend de l'eau en quantité relativement importante et bien déterminée dès sa préparation, on ne court plus le risque de voir la composition changer du fait de l'hygroscopie de l'un de ses constituants et les compositions selon l'invention présentent une stabilité exceptionnelle par rapport aux compositions connues.The water present in the liquid fuel composition according to the invention has the effect to lower the combustion temperature. The inventors have noticed that this is not a disadvantage if certain particular constituents are present in weight ratios very specific. This water may already be present in propylene glycol so that it is not no need to resort to the purchase of particularly expensive anhydrous products. Water can also come, for all or part of the water of hydration of the colorigenic agent. Finally, we can also add water directly to the composition. Since the composition includes water in relatively large quantity and well determined as soon as it is prepared, we do not run the risk of the composition changing because of the hygroscopy of one of its constituents and the compositions according to the invention have an exceptional stability compared to the compositions known.

On veillera donc, selon un mode de réalisation préféré, à saturer ou quasi-saturer la composition avec de l'eau.It will therefore be ensured, according to a preferred embodiment, to saturate or almost saturate the composition with water.

Les agents colorigènes selon l'invention sont les sels de sodium et/ou de lithium des acides formique et acétique (seuls ou en mélange) et l'acide borique. La quantité et la nature de l'agent mise en oeuvre dépendra de la couleur que l'on désire conférer à la flamme.The coloring agents according to the invention are the sodium and / or lithium salts of the acids formic and acetic (alone or in admixture) and boric acid. The quantity and nature of the agent implementation will depend on the color that is to be given to the flame.

On notera que les points d'éclairs de ces compositions sont tous compris entre 72 et 82°C et que celles-ci ne comprennent aucun produit toxique. Dès lors, ces compositions sont parfaitement acceptables d'un point de vue commercial.

The compositions of Examples 1 to 6 are liquid and provide a corresponding result perfectly to the expectations expressed above: the observed flame does not choke and is well supported; the color is clearly visible and remains constant; Finally, the wick is hardly consumed. It should be noted that the flash points of these compositions are all between 72 and 82 ° C and that these do not include any toxic product. From then on, these compositions are perfectly acceptable from a commercial point of view. The compositions of Examples 1 and 4 burn with a red color, those of examples 2 and 5 with a green color and those of examples 3 and 6 with an orange color.

As part of this example, we can still improve the visibility of the flame by saturating the lithium acetate mixture (approximately 1% in weight).

Exemple 10Example 10

La composition de l'exemple 6 a été durcie en y incorporant 1 % en poids d'un copolymère bloc SBS. La composition obtenue est pâteuse et peut être mise en forme de façon à réaliser une bougie en y incorporant une mèche appropriée. La bougie ainsi préparée brûlé avec une flamme de couleur orange. La flamme observée ne s'étouffe pas, est bien soutenue.The composition of Example 6 was cured by incorporating 1% by weight of a block copolymer SBS. The composition obtained is pasty and can be shaped so as to produce a candle by incorporating a suitable wick. The candle thus prepared burned with a flame of orange color. The observed flame does not choke, is well supported.
