Abstract

The invention relates to a high-thermal-conductivity modified polyphenyl ether material and a preparation method thereof. The polyphenyl ether material is prepared from, by weight, 5-50 parts of polyphenyl ether, 5-20 parts of polystyrene, 3-8 parts of toughening agent, 30-70 parts of thermal conductive filler, 0.2-3 parts of lubricant and 0.2-0.5 part of antioxidant. The polyphenyl ether material is prepared in the steps that 1, the thermal conductive filler and the lubricant are weighed and pre-mixed to obtain pre-mixed thermal conductive filler; 2, polyphenyl ether, polystyrene, the toughening agent and the antioxidant are weighed and mixed evenly with the pre-mixed thermal conductive filler to obtain a mixture; 3, the mixture is added in a screw extruder and subjected to melting, extruding, strip molding and cutting into particles to obtain the target product. Compared with the prior art, the polyphenyl ether material has the advantages of being good in processability, excellent in thermal conductivity, high in production efficiency and the like.

Description

technical field [0001] The invention relates to a polyphenylene ether material and a preparation method thereof, in particular to a modified polyphenylene ether material with high thermal conductivity and a preparation method thereof. Background technique [0002] With the continuous development of industrial production and science and technology, people have higher and higher requirements for the comprehensive performance of thermal conductive materials, and traditional metal materials can no longer meet the requirements of some special occasions. For example, the rapid accumulation and increase of heat generated by electronic equipment will cause the device to malfunction, so timely heat dissipation has become an important factor affecting its life. Therefore, it is urgent to develop thermally conductive insulating materials with high reliability and high heat dissipation performance to replace traditional materials. Thermally conductive polymer materials, especially ther...
