Patent number: 11851566Abstract: The present invention relates to a compound represented by the formula (II): CB-O-ROS-GC-Zn (II) where CB represents the white filler, O represents one or more oxygen bridge bonds, ROS represents an organo-silane residue, GC represents one or more coordinating groups forming a chelate with zinc in ionic form represented by linear, branched or cyclic alkyl chains, comprising one or more heteroatoms inside or at the end of the alkyl chain, and Zn represents zinc in ionic form coordinated with the coordinating groups, a process for the preparation thereof, and the use thereof in the vulcanisation process of elastomeric compounds.Type: GrantFiled: November 27, 2019Date of Patent: December 26, 2023Assignee: PIRELLI TYRE S.p.A.Inventors: Antonio Susanna, Raffaella Donetti, Thomas Hanel, Roberto Scotti, Barbara Di Credico, Silvia Mostoni, Massimiliano D'Arienzo

Patent number: 11661498Abstract: The present invention relates to a process for preparing a vulcanisable elastomeric compound for tyres, characterised by the use of a particular vulcanisation-activating filler and by the methods of adding additives, in particular the compatibilising agent (silane), which occurs only after completion of the reaction between the activating filler comprising zinc and the fatty acid (stearic acid). The present process, advantageous in itself due to the possible reduction of the times and of the energy required for vulcanisation, allows preparing compounds which, with the same performances compared to the traditional ones, can have a reduced zinc content, and consequently a lower release thereof from tyres during use at an environmental level.Type: GrantFiled: October 9, 2019Date of Patent: May 30, 2023Assignee: PIRELLI TYRE S.p.A.Inventors: Antonio Susanna, Raffaella Donetti, Luca Giannini, Thomas Hanel, Roberto Scotti, Barbara Di Credico

Patent number: 11383554Abstract: The present invention relates to new vulcanisable elastomeric compositions for components of tyres, comprising modified silicate fibres as fillers. The silicate fibres are modified according to the process with controlled pH of the invention. In addition, the invention regards components of tyres, comprising elastomeric materials obtainable by vulcanisation of said compositions, and tyres for vehicles comprising one or more of said components. The vulcanised elastomeric materials according to the invention are characterised by good static and dynamic mechanical properties, in particular by particularly low hysteresis. Advantageously the tyres of the invention comprising one or more of said components have a limited rolling resistance.Type: GrantFiled: October 20, 2017Date of Patent: July 12, 2022Assignee: PIRELLI TYRE S.p.A.Inventors: Luca Giannini, Luciano Tadiello, Thomas Hanel, Elkid Cobani, Barbara Di Credico, Massimiliano D'Arienzo, Roberto Scotti, Franca Morazzoni, Jorge Jose Perez Cacho, Daniel Javier Julve Sebastian

Patent number: 11161944Abstract: The present invention regards a solid master elastomeric composition (masterbatch, MB) comprising silicate fibres with needle-shaped morphology of nanometric size, characterised by high fibre content and uniformity, a process advantageous for the preparation thereof and its use in manufacturing tyres for vehicles. Advantageously the present elastomeric composition allows minimising the drawbacks associated with the handling of the powdery fibres in the manufacturing of compounds for tyres, without altering the final performances thereof.Type: GrantFiled: December 18, 2017Date of Patent: November 2, 2021Assignee: PIRELLI TYRE S.p.A.Inventors: Luciano Tadiello, Valeria Rosaria Cipolletti, Luca Giannini, Thomas Hanel, Maurizio Galimberti, Roberto Scotti, Barbara Di Credico, Franca Morazzoni, Massimiliano D'Arienzo, Irene Tagliaro

Patent number: 11091607Abstract: The present invention relates to new elastomeric materials for the production of tyres for vehicle wheels with good mechanical properties, in particular high moduli associated with low hysteresis values, including new reinforcement materials. Said reinforcement materials are obtainable by derivatising silica—in-situ during the mixing of the elastomeric composition, or previously—with special silanising agents (A) and silsesquioxanes (B), both substituted with reactive alkenyl functionalities.Type: GrantFiled: October 13, 2017Date of Patent: August 17, 2021Assignee: PIRELLI TYRE S.p.A.Inventors: Luciano Tadiello, Luca Giannini, Thomas Hanel, Matteo Redaelli, Massimiliano D'Arienzo, Barbara Di Credico, Roberto Scotti, Franca Morazzoni

Patent number: 7003981Abstract: Using sol-gel techniques, an optical gain medium has been fabricated comprising a glass ceramic host material that includes clusters of crystalline oxide material, especially tin oxide, and that is doped with active ions concentrated at the clusters. The active ions are preferentially located at the nanoclusters so that they experience the relatively low phonon energy of the oxide and are insensitive to the phonon energy of the host. A host with a high phonon energy, such as silica, can therefore be used without the usual drawback of reduced carrier lifetimes through enhanced nonradiative decay rates.Type: GrantFiled: October 1, 2002Date of Patent: February 28, 2006Assignee: University of SouthhamptonInventors: Elizabeth Taylor, Gilberto Brambilla, Norberto Chiodini, Alberto Paleari, Giorgio Spinolo, Franca Morazzoni, Roberto Scotti
