High-fluidity high-tenacity electric conduction polyphenyl ether polyamide composition and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-flow and high-toughness conductive polyphenylene ether polyamide composition and its preparation technology. Background technique [0002] Polyphenylene ether resin (PPE or PPO) is one of the five major engineering plastics, and it is also the most consumed variety among engineering plastic alloys. Because polyphenylene ether has excellent physical and mechanical properties, heat resistance and electrical insulation, low hygroscopicity, high strength, good dimensional stability, and good creep resistance at high temperatures, it is widely used in home appliances, office and Communication equipment, automobile industry and chemical industry and other fields. However, polyphenylene ether has poor chemical solvent resistance and poor molding process, and the polyphenylene ether polyamide alloy effectively overcomes the shortcomings of polyphenylene ether's poor mol...

AI Technical Summary

Problems solved by technology

[0004] Due to the high viscosity of the conductive substance, its addition causes the fluidity of the matrix material to drop too much, and it is difficult to form and process between thin walls.

Secondly, it has a great influence on the toughness of the matrix material, and the impact strength drops too much

[0005] For some application fields, the toughness of the material is relatively high, the wall thickness of the part is relatively thin, the fluidity of the material is high, and the product is difficult to form and process, the current material cannot meet the requirements.
