Title (EN) A METHOD FOR PREPARING A CONDUCTIVE PLASTIC PRODUCT
(FR) PROCEDE DE PREPARATION D'UN PRODUIT EN PLASTIQUE CONDUCTEUR
Abstract:
(EN) The invention relates to a method for preparing a conductive plastic product in connection with injection moulding, in which method the product is formed from a molten plastic mixture such that the raw material is plasticized in a cylinder by means of a feeding screw (7) and injected into a mould (9). A doping agent (3) is added to a molten dopable conductor polymer (1) or to a molten mixture of a dopable conductor polymer (1) and a matrix plastic (2) after plasticization in a cylinder (5) of an injection-moulding machine (4) before injection into the mould (9) for obtaining conductivity.
(FR) L'invention se rapporte à un procédé de préparation d'un produit en plastique conducteur se rapportant au moulage par injection, dans lequel on réalise le produit à partir d'un mélange de plastique fondu, de vis transporteuse (7) et à l'injecter dans un moule (9). On ajoute un agent de dopage à un polymère conducteur fondu (1) à doper ou à un mélange fondu de polymère conducteur (1) à doper et d'une matrice plastique (2), après plastification dans le cylindre (5) d'une machine de moulage par injection (4), avant injection dans le moule (9) pour obtenir la conductivité.
