Abstract

L'invention concerne un procédé pour la préparation d'un mélange élastomère thermoplastique electro-conducteur. Il s'agit d'un procédé de préparation de mélanges contenant 100 parties d'un polymère caoutchouc EP ou EPDM 25 à 250 parties d'un polymère essentiellement cristallin de propylène et du noir de carbone, caractérisé en ce qu'on utilise 1 à 25 parties d'un noir de carbone dont l'absorption d'huile (DBP) est supérieure à 150 m1/100 g et l'indice de porosité est supérieur à 100 m**2/g. Par préférence, le polymère EP ou EPDM a une cristallinité aux rayons X inférieure à 4 %-poids et une résistance aux tractions supérieure à 10 kg/cm**2 et le polymère de propylène est un copolymère séquencé de propylène et d'éthylène ayant une teneur en éthylène de 1 à 25 %-poids et une cristallinité aux rayons X supérieure à 25 %-poids. Les mélanges peuvent être utilisés dans les cas nécessitant une bonne conductibilité électrique combinée d'une facilité de mise en oeuvre, par exemple pour la fabrication de câbles ou de pièces moulées destinées à être laqués selon le procédé électrostatique comme il y a les pare-chocs d'automobiles et les cache-joints.
