Abstract

The invention discloses an electric-conduction polyphenyl ethe / polyamide composition and preparation method thereof. The electric-conduction polyphenyl ethe / polyamide composition comprises, in parts by weight, 25-35 parts of polyphenyl ether , 40-55 parts of polyamide, 4-7 parts of a compatibilizer, 7-10 parts of a flexibilizer, 1-5 parts of electric-conduction carbon black, 3-9 parts of carbon fiber, and 0-2 parts of a coupling agent. The preparation method of the composition comprises: firstly putting electric-conduction carbon black or electric-conduction carbon black processed by the coupling agent, polyphenyl ether, polyamide, the compabilizer and the flexibilizer in a high-speed mixer for mixing, then adding the mixture through a first-segment charge port of a double-screw extruder, adding employed carbon fiber through a forth-segment cylinder of the double-screw extruder, and then performing extrusion by controlling the rotation speed of the double-screw extruder to be 1050-1200 rpm and the temperature to be 240-275 DEG C, so as to obtain the electric-conduction polyphenyl ether / polyamide composition which is high in mechanical strength, simple in production technology, good in product appearance and good in electric conductivity.

Description

technical field [0001] The invention relates to a conductive polyphenylene ether / polyamide composition, a preparation method and application thereof, and belongs to the field of polymer materials. Background technique [0002] Compared with metal materials, polymer materials are relatively light in weight, not easy to be corroded, low in price, easy to process, low in production energy consumption, and small in pollution, making them more and more widely used in current practical applications. Some fields have replaced metal materials. However, polymer materials do not have the properties of metal materials in some aspects, which is not conducive to processing and application. For example, unmodified materials not only have poor mechanical properties and thermal properties, so some additives are usually added to improve their mechanical properties; In practical application, it is necessary for the material to have certain characteristics that are beneficial to the actual pr...
