Radicals with unsaturated aliphatic groups, such as vinyl, allyl, hexenyl or cyclohexenyl, may be present.
In addition to the previously mentioned ingredients, emulsions according to the invention can preferably contain other ingredients such as fillers, for example, preferably aluminum oxide, aluminum hydroxide, pigments and stabilizers.
This means a significant saving of energy, time and money. Health care technology Another object of the invention is a process for coating textile substrates, characterized in that aqueous emulsions of the invention are applied onto a fabric and cured in the di on textile substrates and a step the coated textile is dried.
The sum of o and p can be betweenpreferablymore preferably Wenn die Diorganopolysiloxane verschiedene Diorganopolysiloxaneinheiten enthalten, kann eine statistische Verteilung oder eine Blockverteilung vorliegen. Polyamide or polyester fabrics finished with the products of this invention by the process of this invention can be used with particular advantage for manufacturing airbags for motor vehicles.
Mechanical systems and components for general use The vulcanization takes place in one operation at the same time as the drying and shrinking process. It can tissues from all weaves, nonwoven fabrics, knitted fabrics, scrims, knitted fabrics of all common yarns and fibers, natural fibers such as cotton, glass, wool, silk, synthetic fibers such as polyamides, polyesters, rayon, polyethylene, polypropylene, polyurethane, silk, rayon, cellulose coated become.
Aqueous emulsions based on addition-crosslinked silicone systems, containing carbon black as a further component. United States Patent Air bag coating composition and air bag. Aqueous emulsions without silicone resin of addition-crosslinking organopolysiloxanes are described for coating release papers in DE-A and for finishing textile materials in EP-B To avoid premature crosslinking, the emulsions of the invention are stored in at least two different components.
Process for coating substrates with aqueous emulsions containing organopolysiloxanes. Company organization, management and quality. The carbon black dispersion can have a solids content of preferably 1 to Examples are sulfonic acid and its salts which can act as emulsifier and also alkylsulfonates, such as sodium laurylsulfonate, benzenesulfonates substituted by aliphatic hydrocarbyl radicals, such as sodium dodecylbenzenesulfonate, naphthalenesulfonates substituted by aliphatic hydrocarbyl radicals, polyethylene glycol sulfonate and lauryl phosphate, polyethylene oxide, polypropylene oxide, interpolymers of ethylene oxide and propylene oxide, stearates and phosphates.
Bei den Gruppen mit aliphatischen Mehrfachbindungen handelt es sich vorzugsweise um Vinylgrupppen oder Allylgruppen, wobei Vinylgruppen besonders bevorzugt sind. There is no need for an additional coating process.
In the present invention, the amounts of platinum catalyst used is generally between 3 and ppm, based on the siloxane content. Testing of organic materials; Separation test on fabric plies bonded together. This is true in the use for manufacturing airbags.
Coated airbags, coating material and coating process – Wacker-Chemie GmbH
The procedure described in Example 3 was repeated, with the difference that no carbon black dispersion is added. However, all radicals described above as R can be present. The organosilicon compounds of components 124 or 5 may each be individual organosilicon compounds or a mixture of different organosilicon compounds. The silane resin 5 may be in the form of an aqueous emulsion.
Particularly advantageously equipped with the inventive products polyamide or polyester fabrics can be used for manufacturing airbags for motor vehicles according to the inventive method. Process for coating substrates with aqueous emulsions containing organopolysiloxanes. The organosilicon compounds can be produced commercially available products or by conventional in-silicone chemistry methods.
Log In Sign Up. Examples of substituted hydrocarbyl radicals are halogenated radicals, such as 3,3,3-trifluoropropyl, 3-chloropropyl or chlorophenyl.
A lick-roller is used to transfer this emulsion to a wet dtex polyamide fabric.
The vulcanization of the silicone coating and drying and shrinkage of the textiles can be effected in a single operation. This gives a dn with the following properties: All prior art coating processes require a separate coating step after the washing and drying.
EP Silicone coated base material and air bag base material. According to the invention, there is provided an aqueous silicone system which is applied to the fabric directly after washing while it is still wet and can be vulcanized during the drying step. The present invention relates to aqueous emulsions, a process for preparing them, materials prepared using the aqueous emulsions, a process for dinn organic fibers using such aqueous emulsions, and textile substrates coated with the emulsions.
In the inventive method, the aqueous emulsions according to the invention can be preferably applied to wet textiles that come directly from a washing or cleaning 533530. One component comprises the siloxanes with the unsaturated aliphatic groups, another component comprises the siloxanes with Si-attached hydrogen. Shipping Delivery Order tracking Returns. The coating according to the present invention confers a better aging resistance to the fabric.
Coated textile substrates characterized in that textile substrates with emulsions according to one or more of claims 1 to 4 or produced are coated according to claim. This is particularly desirable and advantageous in the case of wovens used for manufacturing airbags.
Rubber and plastic industries The organosilicon compounds may each be one type of such organosilicon compounds as well as a mixture of different organosilicon compounds.
EP Liquid silicone rubber coating composition for application to air bags. The carbon black is preferably carbon black, furnace black or lamp black. Suitable emulsifiers are ionic and nonionic emulsifiers. The inventive coating gives the fabric a better aging resistance and flame resistance. Click for automatic bibliography generation.
