Definitions

  • the invention relates to multilayer protective materials used to sew clothes for firemen and rescue workers operating in areas of high temperature and open fire.
  • the invention may be used in the manufacture of other articles, such as capes, covers, and blankets, which must show increased heat resistance for operation in areas of intense heat radiation and also open fire during fire suppression, including the suppression of burning sources of oil, gas and other substances.
  • Protective clothes made from fire-resistant materials should provide certain comfort when work is being carried on in an emergency area: they should be elastic, sufficiently light, so that they would not constrain movement, be heat-reflective to such a degree that the temperature in the under-the-clothes area would not exceed the value at which a heat stroke may occur, i.e. not be more than 50°C, preferably not more than 30-35°C.
  • a fire-resistant material which is made by joining a metallized polyethylene terephthalate film to a cloth of hollow nonprofiled threads, which are partially filled with air (Patent RU No. 2008044, A 62 B 17/00, 1994).
  • a drawback of the known material is its instability when it falls into an open fire, during a sudden increase of a flow of heat, i.e. the polyethylene terephthalate film melts, baring the cloth, and is subjected to thermal destruction, this affecting the properties of the metal coating: it warps, exfoliates, as a result of which the heat-resistant properties of the clothes are impaired.
  • a heat-reflecting material which comprises a fibrous layer in the form of cloth of heat-resistant material on which a layer of hermetic material, made of filled fluorine-containing rubber, is applied.
  • the latter is joined to a heat-reflecting layer made of one of the metals: aluminum, nickel, chromium, applied by the vacuum deposition method.
  • the layer of metal is coated with a layer of unfilled fluorine-containing rubber (Patent RU 2082469, A 62 B 17/00, 1997).
  • Drawbacks of the known material are its impermeability in respect to moisture vapors released by the human body, a low thermal radiation reflection factor (50-60%), poor adhesion of the metal coating to the layer of fluorine-containing rubber, as a result of which metal particles fall off.
  • a layer of unfilled fluorine-containing rubber which chars in open flame for 3-5 seconds, is additionally applied onto the surface of the metal. Wherein, the heat-resistant properties of the material are impaired, the clothes stop fulfilling their functions.
  • a material for heat-resistant clothes which comprises a fabric base and a layer of volumetric metallized material.
  • Fiber glass which is metallized, applying aluminum in vacuum or by doubling with aluminum foil or with a chrome-plated polymeric film, is used as the volumetric material (Pat RU 2071659, A 41 D 31/00, 1997).
  • Drawbacks of the known material are its insufficiently high reflection factor, unsatisfactory properties in respect to permeability: where the material is doubled with a layer of metal or polymeric film, it acquires air- and vapor-impermeability, including that in respect to moisture vapors released by the human body; where the metal is applied by vacuum deposition onto glass fiber, it becomes moisture-permeable, including in respect to water that is used to extinguish a fire.
  • the material that is the most similar analog to the proposed material is the heat-resistant material comprising a layer of fibrous material, an outer layer of moisture-resistant material with a metallized layer coated with a protective fabric "nomex" of aramide applied thereon, and an inner vapor resistant layer (Patent U.S.A. No. 4502153, 2/81, A 41 D 11/00, 1985).
  • Drawbacks of the known material are the absence therein of vapor- and air-permeability, which does not make it possible to remove the excess moisture from the surface of the body, the low heat reflection factor, which does not make it possible to withstand the power of a heat flow of more than 10 kW/m 2 for a lengthy period, and the multilayer construction.
  • the technical result which is achieved when the invention is carried out is enhancement of the comfort of protective clothes made of the proposed material, which is due to the creation of conditions ensuring the removal of vapors of surplus moisture of the body directly through the heat-resistant material, enhancement of the fire resistant properties, which is due to an increase of the resistance to the action of open fire, preservation of the strength of the material within the period of heat action, an increase of the service life of the clothes, and also simplification of the structure of the material for sewing the clothes, enhancement of its operating properties and effectiveness of the protective action.
  • a heat-resistant fireproof material comprising a heat-resistant fiber substrate and a layer of moisture-resistant material with a metal coating layer applied thereon
  • the layer of moisture-resistant material is made of two layers, one of which comprises a sterically linked polymer having a liquid diffusion coefficient equal or less than 10 -9 cm 2 /sec, the other--a hermetic layer--is made of a rubber-based elastomeric material.
  • the heat-resistant material comprises a porous material selected from the group of polyolefins, fluorine-, chlorine- or silicon-containing polymers with a pore size of 0.01-1.0 ⁇ m as the layer of moisture-resistant material, and aluminum, copper, titanium nitride with a layer thickness of 0.05-0.25 ⁇ m as the metal coating layer.
  • the selection of the composition of the layer of moisture-resistant material, made of a sterically linked polymer, on which the metal coating is deposited, is related to the strength characteristics of the heat-resistant/fireproof material.
  • the liquid diffusion coefficient of the layer is increased to more than 10 -9 cm 2 /sec (10 -8 -10 -6 cm 2 /sec)
  • the heat reflection coefficient of the metal coating and the strength of its engagement with the hermetic layer are reduced.
  • the polymer with the sterically linked structure has high resistance to bending as a result of the presence of crosslinkage, which ensures preservation of the original shape and size of the layer thereby formed during the action of heat.
  • the sterically linked polymer has increased resistance to open fire.
  • Chlorosulfonated polyethylene polytetrafluoroethylene-vinylidene fluoride copolymer, isobutylene-isoprene copolymer, polysulfide polymers (thiocols) and others may be used as the cross-linked polymer.
  • Fluorine-containing, nitrile, polychloroprenene, natural or synthetic polyisoprene, acrylate, polyurethane, epichlorohydrin, silicon and other rubbers may be used as rubbers from which the hermetic layer of the moisture-resistant material, serving to join the fiber substrate and the layer of sterically linked polymer, is made.
  • the heat-resistant fiber substrate may be made from glass fiber, polyaramide, polyimide and other heat-resistant materials.
  • Aluminum, nickel, copper, titanium nitride, steel and others are used as the metal coating layer.
  • the thickness of the metal coating layer for material in which the moisture-resistant layer is made of two layers is 0.15-0.25 ⁇ m.
  • the heat-resistant fireproof material containing a porous material with a pore size of 0.01-1.0 ⁇ m is impermeable for water in a liquid aggregate state.
  • the permeability of the material sharply increases in respect to water, where the pores are less than 0.01 ⁇ m in size, it becomes virtually vapor-air-impermeable.
  • the heat-resistant fireproof material according to a variant of the invention containing aluminum, copper, titanium nitride with a metal layer thickness of 0.05-0.25 ⁇ m as the metal coating layer, has a high thermal reflection coefficient.
  • An increase of the thickness of the metal layer above 0.25 ⁇ m reduces the vapor-air permeability of the material, while a reduction of the thickness to less than 0.05 ⁇ m reduces the thermal reflection coefficient.
  • a heat-resistant fireproof material is produced by applying a hermetic layer of elastomeric material on the base of filled fluorine-containing rubber onto a cloth layer of glass fabric.
  • a layer on the base of chlorosulfonated polyethylene having a thickness of 0.05 mm and a liquid diffusion coefficient equal to 10 -10 cm 2 /sec is applied onto the prepared cloth layer substrate, and a layer of metallic aluminum is applied onto this polyethylene layer by vacuum deposition.
