Definitions

  • the present invention relates to a fire hose used to transport high-pressure gas or fluid to a predetermined location, and more specifically, to a fire hose having excellent durability to prevent hose bursting, while providing excellent flame retardancy and heat resistance so that the hose can be used for purposes such as firefighting and gas torches.
  • a hose is a pipe used to transport fluids such as water, gas, or flowable soil, and can be manufactured from a material with excellent flexibility so that it can bend freely.
  • hoses lack flame retardancy, so when used for this purpose, parts of the hose can be easily damaged by flames or extreme heat. If the hose is damaged in this way, not only can there be a risk of a safety accident, but in the case of fire hoses, the damage can cause water to leak out in the event of a fire, making them unusable.
  • the PVC hose has the advantage of being cheaper and easier to manufacture than the rubber hose, but it has the disadvantage of being weak to heat due to the nature of the PVC material. Accordingly, most PVC hoses are manufactured by mixing rubber components and antioxidants into PVC to compensate for the disadvantage of being weak to heat.
  • the main purpose of the present invention is to provide a fire hose having excellent flame retardancy, heat resistance and safety while increasing durability and preventing bursting of the hose.
  • the mobile fire suppression equipment which is a means for solving the problem of the present invention, comprises: a base frame connected by at least one pair of support bars intersecting in the horizontal and vertical directions so as to protect a predetermined structure; according to one aspect of the above-described basic invention, a tubular inner cover; a fabric interwoven layer formed in the form of a mesh on the outer circumferential surface of the inner cover, including a first yarn continuously wound in a spiral shape at an angle of 105 to 110° on an outer circumferential surface of the inner cover, and a second yarn continuously wound in a direction intersecting the first yarn and overlapping the first yarn; and a tubular outer cover formed to cover the fabric interwoven layer on the outer circumferential surface of the inner cover.
  • the inner shell comprises a resin, and, with respect to 100 parts by weight of the resin, 45 to 53 parts by weight of a first plasticizer, 13.315 to 16.273 parts by weight of a second plasticizer, 2.151 to 2.629 parts by weight of a stabilizer, 0.653 to 0.799 parts by weight of a fat saccharide, 0.348 to 0.426 parts by weight of an antioxidant, 0.348 to 0.426 parts by weight of a UV stabilizer, and 0.061 to 0.075 parts by weight of a pigment
  • the outer shell comprises a resin, and, with respect to 100 parts by weight of the resin, 44.995 to 54.993 parts by weight of a first plasticizer, 13.307 to 16.265 parts by weight of a second plasticizer, 5.397 to 6.597 parts by weight of a stabilizer, 0.349 to A fire hose is provided, comprising 0.427 parts by weight of an antioxidant, 0.349 to 0.427 parts by weight of a UV stabilizer, 17.984 to 21.98 parts by weight of
  • the first and second yarns of the fabric interwoven layer can be polyester reinforcing yarns.
  • the fabric woven layer can be formed by weaving or knitting the first and second yarns in an over and under pattern.
  • the vibration transmitted from the pump is reduced, and the hose has excellent durability, thereby preventing bursting of the hose and improving its lifespan.
  • the hose has excellent flame retardancy and heat resistance, so that it can be used as a fire hose required at a fire scene or can be used appropriately with a gas torch for cutting and welding work.
  • the lining (10) may have excellent durability, flame retardancy, and heat resistance by including various types of additives described above.
  • the first yarn (21) is continuously wound in a spiral shape at an angle of 105 to 110° on the outer surface of the inner skin (10).
  • the second yarn (22) is wound continuously in a spiral shape on the outer surface of the inner lining (10) so as to overlap with the first yarn (21) in a direction intersecting with the first yarn (21).
  • first and second yarns (21, 22) may be composed of a compound yarn made by plying two or more basic yarns.
  • the outer shell (30) is formed to cover the fabric interwoven layer (20) on the outer surface of the inner shell (10) and is formed in a tube shape.
  • the outer shell (30) may be made of a material including rubber or resin to ensure flexibility.
  • the above stabilizer may be a material including zinc stearate, magnesium aluminum hydroxy carbonate and stearic acid.
  • the filler may use CaCO 3 .
  • the above second flame retardant may be antimony trioxide (Sb 2 O 3 ), which may form a gas phase when combusted due to a fire and stop free radical reactions, thereby implementing a flame retardant effect.
  • Sb 2 O 3 antimony trioxide
  • the above calcium borate (Ca 2 B 2 O 5 ⁇ H 2 O)) is a component that acts as a flame retardant and smoke inhibitor and may further include calcium magnesium silicates.
  • the above UV stabilizer may be 2-Hydroxy-4-(Octyloxy)Benzophenone, and may play a role in preventing plastic from decomposing by selectively absorbing ultraviolet rays from sunlight and converting them into heat energy or extinguishing free radicals generated by decomposition from ultraviolet rays.
  • the fire hose of the present invention has improved flame retardancy and can be used for applications requiring flame retardancy, for example, as a gas torch or fire hose for performing cutting and welding work.
  • the outer shell (30) may have flame retardancy of VO32 grade and excellent heat resistance by including various types of additives described above.
  • Figure 4 is a material property table for a fire hose according to one embodiment.
  • the inner cover contains 15 parts by weight of dioctyl adipate.
  • the inner diameter of the hose is 12.5 mm
  • the outer diameter is 19.2 mm
  • the hood is 3 mm.
  • the hose of one embodiment exhibited a pressure length change rate of 0.95% at 80 bar and 2.88% when the temperature was raised to 100°C at the same 80 bar, and a pressure outer diameter change rate of 9.38% at 80 bar and 10.52% when the temperature was raised to 100°C at the same 80 bar, indicating that the hose has excellent durability, and that the pressure length change rate and the pressure outer diameter change rate do not change significantly even when heated.
  • the fire hose (100) configured in this manner has better cold resistance and heat resistance than conventional PVC hoses, is lightweight, and has excellent flame retardancy, heat resistance, and durability, so it can be appropriately used in various fields requiring flame retardancy.
  • it can be used as a fire hose, or can be used as an oxygen gas hose because it can prevent the surface of the hose from melting due to metal shavings that fall on the surface of the hose.
