Definitions

  • the invention relates to a method for manufacturing coloured paraffin and/or stearin in powder form.
  • Paraffin and stearin in powder form are the raw materials used in the candle industry for moulding candles and tea-warmers. It is known to melt paraffin in a melting pot at a temperature of 70 - 90°C (depending on the melting point of the paraffin used and on the process used by the manufacturer) .
  • the molten paraffin or stearin is injected into a cooling space or a rotating cooling drum with great force.
  • the injected paraffin is deposited in a form resembling sand grains (candle sand) on the container bottom.
  • a colorant is added in the melting pot, coloured candle sand is obtained.
  • the quality of this product is the same as that of the raw material (the paraffin being used) , taking into account the expected influence of the added colorant.
  • the colorant coats the grain (candle sand) surface and provides an impression of coloured candle sand.
  • a mechanical bond (mixing by force) is obtained, which bond will remain as long as the prevailing conditions force the materials to do so.
  • the two materials (paraffin, colorant) are separated again upon liquefying.
  • the addition of said pigments has a substantial adverse effect on the combustion characteristics of the raw material. This problem becomes visible when the final product is being used.
  • the undissolved particles clog the taper (bad combustion) .
  • thich tapers are used, with the risk of overheating of the paraffin (flames) , in particular with products which are placed in a closed container (glass tea-warmer holders etc.).
  • the colouring particles will sink, resulting in the colorant remaining behind after the paraffin has been burnt (difficult to clean, waste, etc.).
  • the object of the invention is to eliminate the above drawbacks.
  • a method according to the invention is characterized in that said paraffin and/or said stearin in powder form is (are) coloured in cold condition by means of a colorant.
  • One embodiment of a method according to the invention is characterized in that the colorant is an organic colorant.
  • One embodiment of a method according to the invention is characterized in that said organic colorant(s) contain(s) AZO and/or DISAZO and/or ANTHRAQUINONE.
  • Another embodiment of a method according to the invention is characterized in that said colorant is dissolved in a solvent before being added to the paraffin.
  • One embodiment of a method according to the invention is characterized in that said dissolved colorant is diluted with water and/or alcohol.
  • One embodiment of a method according to the invention is characterized in that said diluted dissolved colorant is added while mixing said paraffin and/or stearin.
  • candle sand paraffin and/or stearin in powder form
  • (uncoloured) candle sand obtained by means of known methods may be used as the raw material.
  • An organic colorant in dry or liquid form is used as the colorant.
  • AZO yellow
  • DISAZO BISAZO
  • red red
  • organic colorants possess the property of penetrating into other materials, especially when such materials are of organic nature also in solid form. This property (chemical reaction) can be influenced as regards speed and quality.
  • a solvent for example white spirit, turpentine or acetone
  • alcohol and/or water are added at this stage, the colorant in the desired diluted condition is obtained.
  • the diluted colorant solution is then uniformly sprayed over the candle sand whilst simultaneously stirring the candle sand.
  • the same process may be used on granulated material. For example, blocks of (compressed) paraffin and several other paraffin products (in the candle industry) may be dipped in a solution containing a desired quantity of colorant.

Abstract

Pour obtenir de la paraffine ou de la stéarine colorée sous forme de poudre (sable de bougie), on doit colorer cette paraffine ou cette stéarine. Cette opération de coloration a été jusqu'à présent effectuée pendant la production du sable de bougie. Ce procédé a pour inconvénient que la machine utilisée pour cette opération doit être nettoyée chaque fois qu'une nouvelle couleur est utilisée. Cette invention propose un procédé pour colorer le sable de bougie sous forme de poudre dans un processus à froid.
