Abstract
(EN)
A method for injection compression molding of a conductive thermoplastic resin composition, comprising an injecting and filling step for injecting and filling the conductive thermoplastic resin composition in a cavity space (13) with an interval of 0.5 to 5.0 mm formed by the mating faces (11a) and (12a) of molds (11) and (12) heated to a mold temperature of 150 to 250°C and a compressing and shaping step for bringing a compressing rate to 1.0 to 20 mm/sec and a compressing pressure to 10 MPa by closing the space after completing the filling. Since a molding thus obtained comprises conductive fillers uniformly distributed therein at a high content, the molding can be applied to a separator for fuel cell.

Un procédé de moulage par compression par injection d'une composition de résine thermoplastique conductrice, comprenant une étape d'injection et de remplissage afin d'injecter et de remplir l'espace d'une cavité (13) par la composition de résine thermoplastique conductrice, un intervalle de 0,5 à 5,0 mm étant formé par les faces appariées (11a) et (12a) des moules (11) et (12) chauffés à une température de moulage de 150 à 250 °C, et une étape de compression et de mise en forme pour apporter une vitesse de compression de 1,0 à 20 mm/s ainsi qu'une pression de compression jusqu'à 10 MPa en refermant l'espace après avoir achevé de remplissage. Du fait qu'un moulage ainsi obtenu comprend une teneur élevée de charges conductrices réparties uniformément dans celui-ci, le moulage peut être appliqué à un séparateur pour pile à combustible.
