  • the combustible material for candle of the invention is characterized in that it comprises in its composition less than 20% of a polymer such as a tri-block copolymer.
  • the copolymer is of the type of those sold under the name "KRATON” by the company SHELL CHEMICAL (Brands filed).
  • the combustible material for candle of the invention is characterized in that it comprises in its composition between 5% and 8% of polymer.
  • the invention also relates to a method of manufacture of a candle or combustible material for a candle characterized in that it consists in heating in a main stage one or several oils mixed with an antioxidant at a temperature higher than 125 ° C to incorporate a polymer into the mixture.
  • this manufacturing process includes a step intermediate which consists in coating the wick with a mixture similar to that used to form the fuel but where the mineral oil or the oil mixture was replaced with paraffin.
  • the invention also covers a candle characterized in that its combustible material is formed by at least 90% of an oil mineral or a mixture of mineral oils whose point temperature flash is greater than 200 ° C, between 5% and 8% of a polymer and a antioxidant.
  • FIGS 1 to 3e illustrate the candle of the invention and its process Manufacturing.
  • FIG. 1 illustrates in cross section the candle of the invention.
  • FIGS 3a to 3e illustrate schematically in section transverse the method of manufacturing the candle of the invention.
  • Figure 3a shows the mixture of oils and antioxidant.
  • FIG. 3b illustrates the heating of the oils and the incorporation of the polymer.
  • Figure 3c shows a waxed and crimped wick.
  • Figure 3d illustrates the filling of the candle.
  • Figure 3e shows the cooling thereof.
  • the candle bearing the general reference (1) is formed by a combustible material (2) in which is arranged at least a wick (3). It can be placed in a container (4) or be presented unmolded. It can be transparent and can advantageously be decorative or fragrant and contain elements decorative elements incorporated directly into the combustible material (2) or arranged on the external face of said material.
  • the combustible material (2) of the spark plug (1) has a flash point whose temperature (T) is higher than 200 ° C, the flash point of a fuel representing the temperature above which the material ignites automatically.
  • the candle (1) of the invention is formed using a combustible material whose flash point temperature is high, above 200 ° C.
  • the fuel used has a flash point temperature measured in a closed cup of 225 ° C, the measurement of the flash point temperature under conventional conditions of use giving an even higher value.
  • the candles are generally made with fuels whose flash point is between 150 and 180 ° C, in particular due to the fuel manufacturing process which requires the use of raw materials and in particular oils having a low flash point and a low viscosity to promote the incorporation of polymers.
  • the combustible material (2) of the spark plug (1) is consisting of a mixture of several products and includes in particular at least one mineral type oil (5) having a flash point greater than 200 ° C, at least one polymer (6) and at least one antioxidant (7).
  • oil (5) can advantageously have a flash point equal to 225 ° C or 250 ° C.
  • the polymer (6) is advantageously a polymer of petroleum origin. It is intended to solidify the mixture obtained.
  • the oil (5) used is of the type mineral, a white oil such as those sold by SHELL, ESSO or TOTAL FINA (Trademarks), for example.
  • the material fuel (2) comprises a mixture of a mineral oil having a high flash point greater than 200 ° C, for example equal to 250 ° C and a second mineral oil whose viscosity and point temperature flash are weaker than those of the first oil like for example equal to 225 ° C.
  • the proportion by weight of the second oil can advantageously be less than 30%.
  • the oils (5a, 5b) are mixed with stirring.
  • This mixture can operate cold or at room temperature or be performed preferably hot.
  • An agent is incorporated into the oil mixture antioxidant (7) in a preliminary step before the mixture (5a, 5b) has reached the temperature of 60 ° C.
  • the main stage of the manufacturing consists in heating the oil obtained (5, 5a, 5b, 7) to bring it to a temperature of at least 125 ° C, the temperature from which incorporates the desired polymer into the mixture. We maintain during this main stage the temperature of the mixture around 155 ° C. while continuing the agitation as shown in Figure 3b, until obtaining the complete dissolution of the polymer (6) in the oil mixture.
  • the polymer used is advantageously a triblock copolymer of the type of those marketed under the name "KRATON” by the Company SHELL CHEMICAL, such as “KRATON 1650 E” (Trademarks), by example.
  • the polymer content of the combustible material is less than 20% by weight.
  • this comprises between 5 and 8% of polymer, it comprises a mixture mineral oil which forms more than 80% of the fuel and which contains oil such as Shellflex 430 FC (Trademark) at 88.01% by example and oil such as Shellflex 270 FC (Trademark) by example at 5.00%, said oils being marketed by SHELL (Registered trademark), as well as an antioxidant (7).
  • oil such as Shellflex 430 FC (Registered trademark) at 88.01% by example and oil such as Shellflex 270 FC (Trademark) by example at 5.00%, said oils being marketed by SHELL (Registered trademark), as well as an antioxidant (7).
  • SHELL Registered trademark
  • the mineral oil used is formed with a single oil such as Shellflex 430 FC (Registered trademark) from SHELL (Trademark) mentioned above with a content higher than 90%, without however, depart from the scope of the invention.
  • the mixture obtained is heated in a main stage to one temperature (T1) of at least 125 ° C to incorporate the polymer (6), as shown in Figure 3b.
  • T1 temperature of at least 125 ° C
  • An intermediate step is to coat the wick of a substantially similar mixture containing paraffin before crimping it using a patch (8) at its lower end, as as shown by the crimped wick illustrated in FIG. 3c.
  • This intermediate step is carried out industrially using rolls of wicks which are drop the wick through a bath containing the mixture of paraffin and polymer then in a die and in a cooler.
  • the manufacturing process consists in positioning the drill bit (3) thanks to its crimped disc (8) and possibly one or more elements decorative (9) in a container (4) advantageously transparent and pour the mixture of oil, polymer and antioxidant into the container to partially cover the wick with combustible material (2). Then, the candle (1) is cooled as shown in Figure 3e either accelerated way using a cooling tunnel either so natural so that its combustible material (2) resumes a solid form at room temperature.
  • the dissolution of the polymer (6) in the mixture of oils (5a, 5b) or in a single oil (5) is carried out at a temperature of at least 125 ° C and advantageously equal at 160-170 ° C whereas, in the prior art, the incorporation of polymers takes place at temperatures around 100 ° C so as not to deteriorate the oils used.
