Definitions

  • the invention relates to flame-retardant, flexible materials, in particular textiles.
  • FR-A-2 125410 describes a flame-retardant flexible material in which a solution of diammonium phosphate is printed as a pattern in the form of dots or lines in such a way that zones of high concentration alternate with zones in which there is little or no flame retardant. Instead of the usual uniform distribution by immersing the substance in a highly dilute solution of diammonium phosphate, a point concentration of this flame retardant is to be achieved here.
  • a flame retardant in the form of dots is printed on textiles. It is a specific brominated phosphoric acid ester and not a pigmented flame retardant.
  • DE-A-2 105 019 describes fabrics in which at least two auxiliaries of different functions are applied to the surface of a fabric. B. patch-like zones is applied and the other aid is applied distributed at least in a part of the rest of the area. One of the two aids of different functions can also be a means of flame retarding the fabric.
  • the invention has for its object to provide flexible, in particular textile, materials using pigment or powder flame retardants in combination with binders in a flame retardant manner that good wearing properties result with excellent protection. This also includes the possibility of using flame retardants that have not previously been used for textiles.
  • this object is achieved with a flame-retardant flexible material in which the flame retardant is printed in the form of piles or dams in that the piles or dams of the printed pattern have a height of 0.01 to 1 mm and a diameter or one Have a width of 0.05 to 2 mm and cover 20 to 80% of the surface of the flexible carrier and either a powdered flame retardant, which forms a fire-resistant layer by foaming, or powdered flame retardant in the form of bromine compounds or combinations of antimony trioxide with a halogen dispenser and in contain a binder in both cases.
  • the piles or dams of the printed powdery flame retardant preferably have a diameter or a width of 0.2 to 1 mm.
  • the design of the print ensures that the printed pattern of the flame retardant covers only 20 to 80%, preferably 30 to 70%, of the surface of the flexible carrier.
  • the powdered flame retardants can be carbonizing and fire-suffocating as well as barrier layer-forming flame retardants.
  • So-called intumescent agents are also very suitable, they contain substances that foam up when they heat up, carbonize from 200 to 300 ° C, solidify and form a fine-pored, well-insulating cushion.
  • the pigment-like flame retardants known for plastics can also be used, the flame-retardant effect of which can be enhanced by so-called synergists or certain plasticizers or the binders.
  • Self-extinguishing plastics especially those with a higher halogen content, can also be used alone or in combination with other known flame retardants.
  • powdered flame retardants can be used, which are compatible with one another in combination with the textile fabric serving as a carrier and are described, for example, in Römpps Chemie-Lexikon, 8th edition, (1981) under the keyword “flame retardants” and the literature references listed here.
  • Suitable, in particular polymeric, binders suitable for printing on the powdered flame retardants chemically belong, for example, to the group of polyurethanes, polyacrylates or elastomers. The latter can also be halogenated, in particular chlorinated or fluorinated.
  • Hotmelt adhesives based on polyamides, polyesters or ethylene-vinyl acetate copolymers (EVA) are also very suitable.
  • the polymeric binders and hot melt adhesives are usually in the form of a dispersion.
  • the polymeric, solidified, for example crosslinked or vulcanized, binders then remain in the printed pattern. Their proportion in the printed pattern of the flame retardant can make up 5 to 200, in particular 10 to 50% by weight, based on the flame retardant.
  • the backing layer for the flame-retardant flexible material according to the invention is for most areas of application, in particular for the production of protective suits, as a rule a textile fabric made of mineral, synthetic or natural fibers. Woven or knitted fabrics are particularly preferred because of their small thickness and high strength.
  • the choice of the backing textile depends on the intended use. In the case of light protective clothing, a composite or mixed fabric made of synthetic or natural fibers and mineral fibers is recommended, with the mineral fiber side being provided with the printed pattern of the flame retardant. The simultaneous weaving of these materials is also suitable.
  • the use of flame-retardant or particularly tear-resistant fibers, such as aramids (KEV-LAR, NOMEX) or polyimides, can be useful for certain purposes.
  • the flexible backing material can be printed not only on one side, but also on both sides, and the adhesive effect of the polymeric binder before it solidifies can be used to produce a composite material which has an interrupted layer from the regularly printed pattern of the bound flame retardant between two flexible, in particular air-permeable backing layers up to about 1 mm thick. Then, for example, these nubs of the flame retardant lie between two webs and are better protected.
  • This composite material can be produced by allowing another substrate layer web to run into the flexible carrier layer immediately after printing on a web, then drying the composite material and laminating it together under the action of pressure and heat.
  • the manufacture of the flame-retardant flexible material according to the invention takes place in such a way that a paste made from, for example, powdered flame retardant, optionally with liquid flame retardants, synergists or plasticizers, a solution or dispersion of the polymeric binder and, if appropriate, customary printing aids is applied to the flexible carrier layer by rotary screen printing in one certain pattern is applied, dried and solidified.
  • a paste made from, for example, powdered flame retardant, optionally with liquid flame retardants, synergists or plasticizers, a solution or dispersion of the polymeric binder and, if appropriate, customary printing aids is applied to the flexible carrier layer by rotary screen printing in one certain pattern is applied, dried and solidified.
  • the polymeric binder is e.g.
  • the latex of optionally halogenated elastomers such as natural, synthetic or silicone rubber, chloroprene or fluoroprene
  • the piles or dams of the bound flame retardant applied in a specific pattern must be removed to remove the volatile ones Latex ingredients are dried.
  • Hot melt adhesives in particular based on polyamides, polyesters or EVA, can also be used as dry powder in addition to as a dispersion. Then the printed piles of flame retardants and hot melt adhesive must be exposed to heat radiation shortly after printing before the printed web is driven into the so-called drying tunnel for final consolidation.
  • the foaming intumescent material which foams when heated, is printed in such a pattern or spacing between the centers of the flame retardants that the print pattern foams together under the action of heat to form a closed protective layer before the textile carrier suffers considerable damage or loses its strength. Once present, the foam can withstand extreme loads for an astonishingly long time. If you applied the fire protection coating by coating or impregnation, you would get a board from the flexible textile carrier that would only be suitable for stationary applications. The printed lumps or dams, on the other hand, only slightly change the handle and the air or water vapor permeability of the textile material. When using a clear flexible support, e.g. B. a glass fiber fabric or a film, remains a considerable light transmission despite the printed points of the insulation protection.
  • a clear flexible support e.g. B. a glass fiber fabric or a film
  • the flame-retardant flexible materials according to the invention offer the same protection as with a full-surface treatment, while the air permeability is still very remarkable and the grip is hardly changed.
  • the color of the flexible carrier is also retained on the unprinted side.
  • the flexible materials, which are flame-retardant according to the invention can be processed into protective clothing for extreme conditions in both civil and military fields.
