Definitions

  • suede also called suede, suede, nubuck leather
  • This active ingredient consists of water repellents such as silicones, fluorocarbon resins, metal soaps, certain complex compounds, waxes - individually or in mixtures - which are dissolved or finely dispersed in solvents such as white spirit, chlorinated hydrocarbons, alcohols, esters, ketones, aromatics.
  • solvents such as white spirit, chlorinated hydrocarbons, alcohols, esters, ketones, aromatics.
  • Liquefied, water-immiscible gases such as chlorofluorocarbons (PFCs), propane, butanes, are used as blowing agents. Compressed gases such as carbon dioxide and nitrous oxide are also used.
  • the active ingredient and blowing agent phases should result in a homogeneous mixture. None of the known impregnating agents is based on aqueous or e.g. B. aqueous / alcoholic solvent systems; they contain purely organic solvents.
  • the ingredients are filled in pressure-resistant tinplate or aluminum cans, which are equipped with commercial
  • FR-A-2 202 515 discloses oil and water repellent compositions for various substrates to be treated, including textiles and leather, with a copolymer (based on a monomer containing fluoroalkyl groups and two, optionally three further monomers), which, if appropriate can be present in a solvent that can be used for the polymerization in solution and then optionally form an aerosol together with a propellant. If a solvent is present in the compositions of the examples, it is always acetone. Also in the description there is no reference to the solvents ethanol, n-propanol or isopropanol.
  • ethylene oxide / propylene oxide copolymers containing aerosols on an aqueous basis are known, which may optionally contain solvents such as. Acetone, aliphatic lower alcohols and Giykole, and especially for perfume or insecticide F q rmultechniken are provided. Neither of these two references describes the problems associated with aerosols with fluorocarbon resin active ingredients, which may have to be solved.
  • the task was to design aerosol impregnating agents for the end user with comparable hydrophobing performance without disadvantageous physiological side effects.
  • hydrophobic substances known per se based on perfluorinated carbon resins fluorocarbon resins
  • fluorocarbon resins which can be diluted with alcohols, as aerosol with propellants, such as. B. Dimethyl ether (DME)
  • DME Dimethyl ether
  • They are suitable for waterproofing leather-sensitive leather without causing physiological damage to the respiratory tract when the spray is inhaled.
  • the composition according to the invention does not have to fear any health impairments, as studies on inhalation toxicology have shown.
  • An inventive, water-miscible blowing agent (B) is preferably a liquefied blowing agent, such as. B. Dimethyl ether (DME).
  • this propellant (DME) is present in combination with the solvent, especially ethanol or isopropanol, a binary system is formed in the impregnation spray.
  • blowing agent (B) can also be a liquefied (but not miscible with water) emulsifiable blowing agent, such as. B. propane, butane or difluorodichloromethane.
  • blowing agents can also be present as blowing agents (B), such as. B. carbon dioxide; nitrogen and nitrous oxide are further examples of compressed blowing agents.
  • the fluorocarbon resins present in the active ingredient (A) are the usual ones, as are offered by several companies for the hydrophobic finishing of leather and textiles.
  • hydrophobic fluorocarbon resins which can be diluted with alcohols, in particular those which contain solutions or emulsions which are stable over a long period of time or
  • FC 214 (20%); FC 228 (27%); FC 229 (20%); FC 390 (10%); FC 453 (20%); FC 461 (30%); Foraperle C 305 (25%); Foraperle P 300 (17%); Foraperle T 140 (30%); Foraperle T 145 (25%); Foraperle T 355 (30%); Foraperle T 344 (31%); Foraperle 1190 (28%); Foraperle T 430; Xeroderm DH 471763 (100%); Nuva F (approx. 20%); Nuva FH (approx. 25%). FC 228 and Foraperle P 300 and C 305 are particularly preferred among these products.
  • the solvent present according to the invention (in active ingredient A) is ethanol, n-propanol or isopropanol.
  • the resulting dilute solution of fluorocarbon resin in the solvent i. H. the active ingredient (A)
  • the blowing agent (B) for. B. dimethyl ether, clear or finely dispersible in pressure-resistant containers.
  • the solvent in combination with the propane or butane blowing agent has also proven itself.
  • the active substances (A) may also contain the auxiliaries customary in sprays of this type.
  • auxiliaries customary in sprays of this type.
  • One of these optional auxiliaries are common anti-corrosion agents (corrosion inhibitors) for tinplate and aluminum cans.
  • corrosion inhibitors include sodium benzoate; Disodium hydrogen phosphate; Vircopet 20, 30 and 40; Deriphat 151 C, Rewo B 3010; Sarcosyl NL 97; Dehyquart SP.
  • fragrance substances of the type customary in this field are also to be mentioned, such as perfume oils which are resistant to water, solvents and propellants, in particular DME.
  • the active ingredient (A) advantageously has the following composition, the amount of the components in each case being given in percent by weight, based on the active ingredient formulation:
  • the amount of active ingredient (A) in the impregnating spray according to the invention can vary depending on its type and the type of blowing agent present. In general, 35 to 65% by weight of active ingredient (A) (based on the finished filling formulation) are available. An amount of active ingredient of 40 to 60% by weight has proven particularly useful.
  • the amount of blowing agent (B) according to the invention can also vary. It is usually 30 to 70% by weight, preferably 35 to 55% by weight of liquefied propellant and 0 to 7% by weight, preferably 0 to 5% by weight of compressed propellant.
  • impregnating spray according to the invention is carried out in the same way as in the known aerosol impregnating agents on the surfaces of leather to be treated, e.g. B. shoes, leather clothing, leather furniture, etc., or of textiles, e.g. B. clothing, times, tarpaulins, umbrellas, etc. Also paper surfaces provided for impregnation can be treated according to the invention.
