The invention discloses a high-fluidity high-tenacity electric conduction polyphenyl ether polyamide composition and a preparation method thereof. The composition consists of the following components in part by weight: 30 to 50 parts of polyphenyl ether, 20 to 55 parts of polyamide, 5 to 20 parts of flexibilizer, 2 to 10 parts of epoxidized soybean oil, 1 to 5 parts of carbon nano tube and 0.5 to 1.5 parts of compatilizer. A small amount of epoxidized soybean oil is added into a material composite system, so that the fluidity and the appearance of the material are improved. The obtained electric conduction polyphenyl ether polyamide composition has the advantages of excellent mechanical property, high compatibility with environment, high heat resistance, high fluidity, glossy surface and high practical value and the like; the surface resistance can reach 102 to 1010 ohm; and the composition is very suitable to be used in a computer and an electronic product, provides electronic screening for the electronic product, prevents an electronic element form being interfered by external electromagnetism, and can also be used in n automobile body panel of components inside and outside an automobile; and the electrostatic spraying of the composition can be performed according to the requirement.
