Title (EN) RADIATION CROSSLINKING EPDM COMPOSITION AND CABLE PRODUCED THEREBY
(FR) COMPOSITION D'EPDM À RÉTICULATION PAR RAYONNEMENT ET CÂBLE AINSI PRODUIT
(KO) 조사가교 EPDM 조성물 및 이것에 의해 제조된 케이블
Abstract:
(EN) The present invention relates to a radiation crosslinking EPDM composition and a cable produced thereby. The radiation crosslinking EPDM composition is characterized by being formulated by adding 30-80 phr of EPDM, to which a crosslinking agent has not been added, 10-50 phr of a PO resin, 5-40 phr of a silicone rubber, 20-30 phr of a flame retardant, 5-10 phr of a crosslinking promoter, 1-5 phr of a crosslinking aid, 5-15 phr of an antioxidant, and 0.25 to 5 phr of a lubricant with respect to 100 wt% of the composition. The cable produced by the composition is characterized by being produced through: a step for performing primary kneading of the composition by means of a kneader; a step for performing secondary kneading of the primary kneaded composition by means of a roll mill; a step for extruding the twice-kneaded composition by means of an extruder, and then cutting to produce a pellet-shaped raw material; a step for extruding a cable of a selected length by means of the extruder by using the produced pellet-shaped raw material; and a step for crosslinking the cable using an electron beam accelerator.
(FR) La présente invention concerne une composition d'EPDM à réticulation par rayonnement et un câble ainsi produit. La composition d'EPDM à réticulation par rayonnement est caractérisée en ce qu'elle est formulée par l'ajout de 30 à 80 phr d'EPDM, auquel un agent de réticulation n'a pas été ajouté, de 10 à 50 phr d'une résine PO, de 5 à 40 phr d'un caoutchouc de silicone, 20 à 30 phr d'un agent ignifuge, 5 à 10 phr d'un promoteur de réticulation, 1 à 5 phr d'un auxiliaire de réticulation, 5 à 15 phr d'un antioxydant, et 0,25 à 5 phr d'un lubrifiant par rapport à 100 % en poids de la composition. Le câble produit par la composition est caractérisé en ce qu'il est produit par : une étape consistant à effectuer un malaxage primaire de la composition au moyen d'un pétrin ; une étape consistant à effectuer un malaxage secondaire de la composition malaxée primaire au moyen d'un laminoir ; une étape consistant à extruder la composition malaxée deux fois au moyen d'une extrudeuse, puis la découpe pour produire une matière première en forme de pastille ; une étape d'extrusion d'un câble d'une longueur sélectionnée au moyen de l'extrudeuse à l'aide de la matière première en forme de pastille produite ; et une étape de réticulation du câble à l'aide d'un accélérateur de faisceau d'électrons.
