| titleOfInvention | Multilayer pipe made of polyamides and fluoropolymer for conveying fuel |
| abstract | une couche extérieure formée d'un polyamide, une couche intermédiaire formée d'un mélange d'unnfluoropolymère et d'un polyméthacrylate d'alcoyle, une couche intérieure, en contact avec l'essence, formée d'unnmélange à matrice polyamide et contenant une phasendispersée polyoléfinique, cette couche pouvant contenir dunnoir de carbone, nLes couches étant successives et adhérentes entre-elles dans leur zone dencontact respective.The present invention relates to a multilayer tube based on polyamides comprising in its radial direction from the outside to the inside at least: an outer layer formed of a polyamide, an intermediate layer formed by a mixture of a fluoropolymer and a polyalkyl methacrylate, an inner layer, in contact with the gasoline, formed of a mixture with a polyamide matrix and containing a dispersed polyolefinic phase, this layer possibly containing carbon black, The layers being successive and adherent to each other in their respective contact zone.n n n According to another form of the invention the inner layer is replacednby two layers, one formed from a polyamide matrix blend containingnone dispersed polyolefinic phase, the other formed from a matrix mixturenpolyamide containing a dispersed polyolefinic phase and carbon black,nthe carbon black charged layer being in contact with the gasoline.n n n The tube of the invention may include an additional layernconsisting of production offcuts or tubes of the invention havingndefects, these scraps or tubes are crushed then melted and coextruded withnthe other layers. This layer can be located between the outer layer and thenintermediate layer or between the intermediate layer and the inner layer.n n n The tube of the present invention is very slightly permeable to petrol andnto its additives and has very good mechanical properties at low ornhigh temperature. In addition by adding black in the inner layer itnbecomes antistatic. Another advantage is that the inner layer in contactnwith essence does not exude. |
