Definitions

  • the present invention relates to a foam fire extinguishing agent, and more particularly to a fluorine-free foam fire extinguishing agent that does not contain a fluorine compound and forms a film that suppresses vapor on a water-insoluble liquid.
  • the water film-forming foam fire extinguishing agent is mainly used for fires of flammable liquids belonging to the fourth category of dangerous substances, and is supplied in a foamed state.
  • a water-insoluble flammable liquid When used in a fire of a water-insoluble flammable liquid, it forms a water film on the flammable liquid while returning (reducing) from a foamy state to a liquid state. This water film formation suppresses the generation of flammable vapor from the flammable liquid, thereby extinguishing the fire.
  • the surface tension of the water film formation foam fire extinguishing agent is required to be low, but in addition, it must satisfy a predetermined foaming performance, does not dissolve in oil, and is heat-sensitive.
  • Various performances as a fire extinguishing agent are required, such as being strong and preventing components from separating or precipitating over a long period of time. Therefore, the water-forming foam fire extinguishing agent has a problem that it is necessary to satisfy these various performances in a well-balanced manner while lowering the surface tension.
  • Patent Document 1 Japanese Unexamined Patent Publication No. 2007-252731
  • a surfactant containing a fluorine-based compound is one of the components. (For example, Patent Document 1).
  • organofluorine compounds such as perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexanesulfonic acid (PFHxS), and these There is a move to regulate the production and use of related substances.
  • PFOS perfluorooctanesulfonic acid
  • PFOA perfluorooctanoic acid
  • PHxS perfluorohexanesulfonic acid
  • an object of the present invention is to provide a foam fire extinguishing agent that does not contain a fluorine compound and can satisfy a predetermined performance.
  • the inventors have diligently conducted tests and researches, and even if it is a fire extinguishing agent containing only a predetermined amount of each of a non-fluorine-based cationic surfactant and a non-fluorine-based anionic surfactant. For example, they have found that they can satisfy the performance as a water-forming foam fire extinguishing agent even if they do not contain a fluorine compound, and have completed the present invention.
  • the foam fire extinguishing agent of the present invention is Cationic surfactant 0.2-3.0% by mass, Anionic surfactant 0.2-5.0% by mass, water and, Is included in a total of 100% by mass.
  • the cationic surfactant is dioctyldimethylammonium chloride, octylethyldimethylammonium etosulfate, octyldecyldimethylammonium chloride, didecyldimethylammonium chloride and dilauryldimethylammonium chloride, didecylmethylpoly.
  • At least one of oxyethylene ammonium propionate is preferable.
  • the anionic surfactant is preferably at least one of pentyl sulfate, octyl sulfate, decyl sulfate and lauryl sulfate.
  • the foam fire extinguishing agent according to the present embodiment contains 0.2 to 3.0% by mass of a cationic surfactant and 0.2 to 5.0% by mass of an anionic surfactant.
  • a cationic surfactant 0.2 to 5.0% by mass of an anionic surfactant.
  • good results can be obtained in the water film formation test even though it does not contain a fluorine compound, and other performances (oil repellency, heat resistance, foaming performance, etc.) can be compatible. It is considered that the reason why good results can be obtained with the above formulation is that the combined raw materials have a relatively large hydrophobic group and form a complex to reduce the surface tension.
  • the cationic surfactant is 0.5 to 1.0% by mass, and the anionic surfactant is 1.0 to 3.0% by mass.
  • cationic surfactants are dioctyldimethylammonium chloride, octylethyldimethylammonium etosulfate, octyldecyldimethylammonium chloride, didecyldimethylammonium chloride, dilauryldimethylammonium chloride, didecylmethylpoly (1-2) oxy. It is preferably selected from any of the ethylene ammonium propionates.
  • the anionic surfactant is preferably selected from any of pentyl sulfate, octyl sulfate, decyl sulfate, and lauryl sulfate. The most preferred combination is didecyldimethylammonium chloride as the cationic surfactant and octyl sulfate as the anionic surfactant.
  • the cationic activator is less than 0.2% by mass and the anionic activator is less than 0.2% by mass, the water film formation test cannot be cleared and the required performance cannot be obtained.
  • the amount of the cationic activator exceeds 3.0% by mass, the solution is separated and the fire extinguishing agent is not established.
  • anionic activators no upper limit of concentration can be found that would disrupt the performance, but cost effectiveness cannot be expected even if the concentration exceeds 5.0% by mass.
  • the foam fire extinguishing agent of the present embodiment conforms to the water film formation test, which has been difficult in the past, and is also good in other performances, despite the formulation not containing the fluorine-based compound. In addition, the availability of raw materials is excellent.
  • Butyl carbitol is a solvent that is also contained in actual fire extinguishing agents. Further, in the actual fire extinguishing agent, components such as an organic solvent such as carbitol, a cationic surfactant, an anionic surfactant, water, and ethylene glycol are added.
  • Test 1.
  • Water film formation test A water film formation test was carried out using each foam fire extinguishing agent sample that was made up to 100% by mass with water. The procedure is as follows. (1) Put 600 ml of cyclohexane having a liquid temperature of 20 ⁇ 1 ° C. in a stainless steel container having an inner diameter of 11.4 cm and an inner glue height of 13 cm. (2) 200 ml of foamed foam is uniformly placed on the cyclohexane oil surface. (3) A conical stainless steel wire mesh (plain weave 80 mesh) is placed so that the tip is immersed in cyclohexane and allowed to stand for 1 minute.
  • plain weave 80 mesh plain weave 80 mesh
  • Diffusion coefficient measurement method The diffusion coefficient of each foam fire extinguishing agent sample was measured by the following procedure. (1) Put each foam fire extinguishing agent sample into a 100 ml measuring cylinder in a measured amount using a measuring pipette, and add water or synthetic seawater to make a 100 ml foam aqueous solution. Stir well and let stand for at least 30 minutes. (2) The surface tension of cyclohexane at 20 ° C. is measured by using the ISO304 ring method or plate method. (3) The surface tension of the aqueous foam solution at 20 ° C. is measured in the same manner as in (2) above.
