Embodiment Construction

[0020] The preparation steps of the impact-resistant conductive polyphenylene ether polyamide compound of the present invention are:

[0021] Adopt high-speed pre-mixing and dispersing one-time extrusion process. First, the polyphenylene ether, polyamide resin, high impact polystyrene, phosphate ester, impact modifier, antioxidant, coupling agent and other additives are dispersed and mixed by a high-speed mixer, and then directly enter the twin-screw extruder Processing, carbon black or carbon fiber (or carbon nanotubes) enters the twin-screw extruder through side feeding for processing, and is extruded, cooled, dried, pelletized and packaged. The temperature of each partition of the screw barrel should be kept at 240-270°C. The aspect ratio of the twin-screw extruder is 38, and the screw speed is 400 rpm.

[0022] According to the above preparation method, the embodiment uses polyphenylene ether as polyphenylene ether with a characteristic viscosity of 0.40dl / g, the polyami...

Abstract

The present invention relates to one kind of high molecular composite material, and is especially one kind of shock resisting conductive polyphenyl ether-polyamide composition and its preparation process. The polyphenyl ether composition consists of polyphenyl ether resin 30-50 wt%, polyamide 20-50 wt%, carbon black 0.3-25 wt%, shock modifier 3-20 wt% and phosphate 1-10 wt%. It is prepared through high speed pre-mixing and dispersing and once extruding. The polyphenyl ether-polyamide composition has high chemical resistance, high mechanical performance, easy forming and other advantages, and is suitable for use as package of electronic devices and in electrostatic coating parts.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to an impact-resistant conductive polyphenylene ether polyamide compound and a preparation method thereof. Background technique [0002] Electronic devices need packaging containers to carry and protect them during production, transportation and use. In order to prevent damage to electronic devices caused by static electricity generated by friction between electronic devices and containers, these containers are all made of conductive plastic. become. [0003] The main components of existing conductive plastics are compounded by plastics, conductive carbon black, carbon fiber or carbon nanotubes and various additives. Carbon fiber and carbon nanotubes have the characteristics of small dosage and little impact on the mechanical properties of the material, but the cost is much higher than carbon black, and the market is currently mainly based on carbon black. [0004] The main plastic ...
