Title (EN) RUBBER COMPOSITION FOR SEISMIC ISOLATION LAMINATES
(FR) COMPOSITION DE CAOUTCHOUC POUR STRATIFIES D'ISOLATION SISMIQUE
Abstract:
(EN) A rubber composition for seismic isolation laminates which has excellent damping and hardening properties. The composition comprises at least a diene rubber and 40 to 160 parts by weight, based on 100 parts by weight of the diene rubber, of a carbon black having a CTAB specific surface area of 120 to 370 (m2/g) and a ratio of a CTAB specific surface area (m2/g) to an iodine adsorption (mg/g) of not more than 1.0.
(FR) L'invention concerne une composition de caoutchouc pour stratifiés d'isolation sismique, qui présentent d'excellentes propriétés d'amortissement et de durcissement. Cette composition comprend au moins un caoutchouc diénique et 40 à 160 parties en poids, par rapport à 100 parties en poids du caoutchouc diénique, de noir de carbone présentant une surface spécifique (CTAB) de 120 à 370 (m2/g) et un rapport entre la surface spécifique (CTAB) (m2/g) et l'absorption d'iode (mg/g) ne dépassant pas 1,0.
