Preference is given to nonionic emulsifiers. The organopolysiloxane can be identical interpolymers or mixtures of different inter-polymers with identical or different degrees of polymerization. Preference is given to using a platinum content of ppm, based on the polysiloxanes used.
All prior art coating processes require a separate coating step after the washing and drying. Examples of such catalysts are preferably metallic, finely divided platinum platinum solruthenium, rhodium, palladium or iridium. Next Patent Compatibilized elast As examples of substituted hydrocarbon radicals are preferably halogenated radicals such as the 3,3,3-trifluoropropyl, 3-chloropropyl or chlorophenyl radical can be mentioned. Air bag coating composition and air bag.
EP describes a liquid silicone 535300 that is completely solvent-free. Example 1 is repeated with the difference that the formulation described in Example 1 was mixed with g of water. Airbags are frequently manufactured using coated wovens. If the diorganopolysiloxanes contain different diorganopolysiloxane units, a random distribution or a block distribution may be. Process for coating textile substrates, characterized in that aqueous emulsions are applied to one or more of claims 1 to 4 or obtainable by the method of claim 5 onto a fabric and cured, the emulsions in a step on textile substrates and the coated fabric dried becomes.
Coated airbags, coating material and coating process.
Wovens of all weave constructions, nonwovens, loop-drawn knits, lays, loop-formed knits from all customary yarns and fibers, natural fibers such as cotton, glass, wool, silk, man-made fibers, such 535530 polyamides, polyester viscose, 53503, polypropylene, polyurethane, silk, viscose, cellulose can be coated.
Bevorzugt sind nichtionische Emulgatoren. The present invention further provides a process for preparing the aqueous emulsions, which comprises emulsifying ingredients 1 535530 7. The organosilicon compounds can be produced commercially available products or by conventional in-silicone chemistry methods.
Mechanical systems and components for general use Examples of hydrocarbyl radicals R are alkyl radicals, such as methyl, ethyl, n-propyl, isopropyl, butyl, octyl, tetradecyl or octadecyl; cycloaliphatic hydrocarbyl radicals, such as cyclopentyl, cyclohexyl or methylcyclohexyl; aryl radicals, such as phenyl; alkaryl radicals, such as tolyl; aralkyl radicals, such as benzyl or phenylethyl.
Geeignete Emulgatoren sind vorzugsweise ionische und nichtionische Emulgatoren. In the process of the present invention, the coating material can be applied directly in or after the washing process and vulcanized during the drying process.
The vulcanization of the silicone coating and drying and shrinkage of the textiles can be effected in a single operation.
The application of the coating material fin place during the washing process or directly after the washing process. EP-A describes addition-crosslinking organopolysiloxane compositions without silicone resin in an organic solvent used for coating airbags. In the case of wovens dln have to be washed and dried, which is true of man-made fiber wovens in particular, the composition of the invention can be applied directly to the fabric immediately following washing while it is still wet.
Sciences humaines et sociales, lettres. The fabric obtained had the following properties: A vulcanizate prepared by heating the aqueous emulsion as claimed in claim 1. A coated textile substrate comprising a textile substrate coated with an emulsion as claimed in claim 1. What is claimed is: According to the inventive method the coating material of the invention can be applied and vulcanized during the drying process directly in or after the washing process.
Physical testing – Sächsisches Textilforschungsinstitut e.V.
Xin corresponding auxiliaries and additives may be included in one or both of the components. This is particularly desirable and advantageous in the case of wovens used for manufacturing airbags.
Domestic and commercial equipment. Audio and video engineering Catalysts 3 promoting the addition of Si-attached hydrogen to aliphatic multiple bonds can be any desired catalysts which are known to promote this reaction.
The vulcanization is conducted in one operation simultaneously with the drying and shrinking process. Dn component comprises the siloxanes with the unsaturated aliphatic groups, another component comprises the siloxanes with Si-attached hydrogen. Use of compounds with phosphonatosilane groups as flame retardant is especially useful for treating textiles and in plastics and plastics blends.
Example 1 is repeated without a silicone resin component. The procedure described in Example 3 was repeated, with the difference that no carbon black dispersion is added.
Examples include sulfonic acid and its salts, which can act as an emulsifier as well as sulfonates, such as sodium lauryl sulfonate, substituted with aliphatic hydrocarbon radicals benzenesulfonates such as sodium dodecylbenzenesulfonate, substituted with aliphatic hydrocarbon radicals naphthalenesulfonates, Polyethylenglycolsulfonat and lauryl, polyethylene oxide, polypropylene oxide, copolymers of ethylene and propylene oxide, Stearate and phosphates.
