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
