Abstract
(EN)
The application discloses methods for recycling polymeric materials, particularly cured rubber e.g. derived from tyres and the like. The polymer material is reduced to particulate form, and subjected to a surface activation treatment, preferably a cold gas plasma treatment. The resulting particles show excellent properties when blended with matrix or binder materials which are then cured or set to form new articles. In particular, the activated surfaces make intimate bonding contact with the surrounding matrix or binder, so that large proportions of particulate material can be recycled into new products which exhibit good performance, e.g. elastomeric performance.
(FR)
L’invention concerne des procédés de recyclage de matériaux polymériques, notamment de caoutchouc vulcanisé, par exemple dérivé de pneus ou analogues. Le matériau polymérique est réduit en une forme particulaire, et soumis à un traitement d’activation de surface, de préférence un traitement par plasma gazeux froid. Les particules résultantes présentent d’excellentes propriétés lorsqu’elles sont mélangées avec des matériaux de matrice ou de liant, qui sont ensuite réticulés ou durcis pour former de nouveaux articles. Les surfaces activées réalisent en particulier des contacts de liaison intimes avec la matrice ou le liant environnant, permettant ainsi de recycler de grandes proportions de matériau particulaire dans de nouveaux produits présentant de bonnes performances, par exemple élastomériques.
