Definitions

  • suede also called suede, suede, nubuck leather
  • impregnation agent only spray articles (aerosols) are available to the end consumer, by means of which impregnation substances and care products can be applied sparingly, evenly and effortlessly to the surface of the leather articles.
  • This application is superior to all other dosage forms offered (e.g. applying impregnation substances in dissolved, liquid form via pump spraying, direct distribution of the liquid from a bottle via a dispenser made of sponge felt or other material).
  • the propellant or propellant mixture is responsible for the application and fine atomization of the actual active ingredient.
  • 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.
  • PFCs chlorofluorocarbons
  • propane propane
  • propane propane
  • 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.
  • 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 which can be diluted with water alone or with water / alcohol mixtures, as aerosol with propellants, such as e.g. Dimethyl ether (DME), can be filled and sprayed. They are suitable for the hydrophobizing of water-sensitive leather without causing physiological damage to the respiratory tract when the spray is inhaled. Health impairments are not to be feared with the composition according to the invention, as studies on inhalation toxicology have shown.
  • a water-miscible blowing agent (B) present according to the invention is preferably a liquefied blowing agent, such as e.g. Dimethyl ether (DME). If this blowing agent (DME) is present in combination with a solvent system (LA) made of water and / or a water-miscible alcohol, in particular ethanol or isopropanol, then a binary or ternary system of DNE, water and / / or alcohol from within the known quantity ranges in the form of a uniform phase
  • a solvent system LA
  • a binary or ternary system of DNE water and / / or alcohol from within the known quantity ranges in the form of a uniform phase
  • a liquefied (water-immiscible but) emulsifiable blowing agent such as e.g. Propane, butane or difluorodichloromethane.
  • blowing agents may also be present as blowing agents (B), e.g. 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 water and / or alcohols, in particular those which contain solutions or emulsions which are stable over a long period of time or
  • FC 208 (approx. 30%); 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 T430;
  • 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 or diluent (LA) present according to the invention is selected from the group: water, preferably deionized water; one with water solvent (LW); and mixtures of water with (LW).
  • Solvents (LW), alone or in a mixture with water, have proven to be water-miscible alcohols, in particular mono- or polyhydric aliphatic alcohols; these are preferably C 1 -C 6 alcohols, such as ethanol, n-propanol, isopropanol, butanol; also glycols, such as ethylene glycol, but also water-miscible ketones are suitable as solvents (LW), such as acetone.
  • the resulting dilute solution of fluorocarbon resin in the solvent (LA), i.e. the active ingredient (A) with the propellant (B), e.g. Dimethyl ether, clear or finely dispersible can be mixed in pressure-resistant containers.
  • a solvent (LA) consisting of the combination of water / alcohol has proven to be particularly suitable here. But also alcohol alone (e.g. in combination with the blowing agents DME, propane or butane) or water alone have proven themselves as solvents (LA) (see also the explanations above for avoiding the known mixture gap of DME / water).
  • the active substances (A) may also contain the auxiliaries customary in sprays of this type.
  • auxiliaries are common anti-corrosion agents (corrosion inhibitors) for tinplate and aluminum cans.
  • corrosion inhibitors common anti-corrosion agents
  • the following are just a few examples: sodium benzoate; Disodium hydrogen phosphate; Vircopet 20, 30 and 40; Deriphat 151 C, Rewo B 3010; Sarcosyl NL 97; Dehyquart SP.
  • fragrances 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, there are 35 to 65% by weight of active ingredient (A) (based on the finished filling formulation). 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.
  • the impregnating spray according to the invention is applied in the same way as in the known aerosol impregnating agents to the surfaces of leather to be treated, e.g. Shoes, leather clothing, leather furniture, etc., or of textiles, e.g. Clothing, tents, tarpaulins, umbrellas etc. Paper surfaces intended for impregnation can also be treated according to the invention.
  • composition according to the invention showed no acutely toxic effect in the test animals, even at very high concentrations (up to 44 g / m 3 ). No mortality was found at this exposure; LC 50 values could not be determined.
  • the numerical data given represent percentages by weight, based on the active ingredient formulation or on the filling formulation.
