Definitions

• the present invention relates to a combustible composition producing a flame of color.
• 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.
• 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.
• 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.
• a fuel composition producing a color flame during its combustion.
• she sought for a purpose such compositions which are colorless or weakly colored in the absence of combustion.
• 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.
• 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.
• 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.
• 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.
• the mixture should not be too volatile (saturation vapor pressure low at room temperature).
• it must have a good diffusion capacity in the wick so that it is not consumed too quickly.
• 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.
• an oil e.g., a bio-mass oil type
• paraffin can be added to provide an oily composition (for use in an oil lamp 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.
• SBS styrene-butadiene-styrene
• 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.
• SE / BS type styrene-ethylene / butylene-styrene
• isocyanate to obtain an "elastomer” type gel
• carbopol for a classic gel.
• 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.
• 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.
• 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.
• 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.
• Example 2 The composition of Example 2 was gelled to elastomer by incorporating therein 3% by weight of a SE / BS block copolymer grafted with about 2% by weight of maleic anhydride.
• the solution obtained is thermo-reversible and has a viscosity ⁇ of about 1000 cPs at temperature room.
• the gel thus obtained burns with a green flame. The flame observed chokes, is well supported; the color is clearly visible and remains constant. We do not observe fumes.
• Example 5 The composition of Example 5 was gelled to elastomer by incorporating 2.5% by weight of a composition of an SE / BS triblock copolymer and an iosocyanate.
• the solution obtained has a viscosity ⁇ of about 1000 cPs at room temperature.
• the gel thus obtained is thermo-reversible and burns with a green flame. The observed flame does not choke, is well supported the color is clearly visible and remains constant. No smoke is observed.
• Example 4 The composition of Example 4 was mixed with biomass oil at a rate of 10 parts (in weight) of the composition according to the invention for 90 parts (by weight) of oil. The resulting mixture was poured into an oil lamp and burned with a red flame. The flame observed is not choked, is well supported. As part of this example, we can still improve the visibility of the flame by saturating the lithium acetate mixture (approximately 1% in weight).
• Example 6 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.
