  • Patent number: 11667788
    Abstract: Melt emulsification may be employed to form elastomeric particulates in a narrow size range when nanoparticles and a sulfonate surfactant are included as emulsion stabilizers. Such processes may comprise combining a polyurethane polymer, a sulfonate surfactant, and nanoparticles with a carrier fluid at a heating temperature at or above a melting point or softening temperature of the polyurethane polymer, applying sufficient shear to disperse the polyurethane polymer as liquefied droplets in the presence of the nanoparticles in the carrier fluid at the heating temperature, cooling the carrier fluid at least until elastomeric particulates in a solidified state form, and separating the elastomeric particulates from the carrier fluid. The polyurethane polymer defines a core and an outer surface of the elastomeric particulates, and the nanoparticles are associated with the outer surface. The elastomeric particulates may have a span of about 0.9 or less.

  • Patent number: 11661498
    Abstract: 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.
