A kind of conductive polyphenylene ether alloy and preparation method thereof

Abstract

The invention discloses a conductive polyphenylether alloy and a preparation method of the conductive polyphenylether alloy. The alloy consists of the following components: polyphenylether resin, nylon resin, conductive carbon black, a compatilizer, a flexibilizer, a coupling agent, an antioxidant, a lubricating agent and a dispersing agent. The preparation method comprises the following two steps: 1, preparing conductive master-batches by using the nylon as a matrix; and 2, blending the polyphenylether, the nylon, the conductive master-batches, the compatilizer, the flexibilizer and the like to prepare a conductive polyphenylether alloy. The nylon is adopted as a second resin component of the matrix in the conductive polyphenylether alloy disclosed by the invention; and compared with the normal polyphenylether / polystyrene alloys, the heat resistance property of the material is better and the oil resistance and the solvent resistance are greatly improved.
