Abstract

The invention relates to a high-strength, high-thermal-conductivity and modified polyphenyl ether material and a preparation method thereof. The polyphenyl ether material is formed by mixing an enhanced modified material and a thermal conductive modified material; the enhanced modified material is prepared from, by weight, 30-50 parts of polyphenyl ether, 5-15 parts of polystyrene, 40-60 parts of glass fibers, 0.3-0.6 part of lubricant and 0.2-0.5 part of antioxidant; the heat-conducting modified material is prepared from, by weight, 12-40 parts of polyphenyl ether, 10-25 parts of polystyrene, 3-8 parts of toughening agent, 40-70 parts of thermal conductive filler, 1-3 parts of lubricant and 0.2-0.5 part of antioxidant. The polyphenyl ether material is prepared by firstly preparing the enhanced modified material and the thermal conductive modified material respectively and then mixing the enhanced modified material and the thermal conductive modified material in batch according to a certain proportion. Compared with the prior art, the polyphenyl ether material has the advantages of being large in mechanical strength, excellent in thermal conductivity, good in processability 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 strength and 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 material...
