Description

technical field [0001] The invention relates to the field of thermally conductive insulating materials, in particular to a high thermally conductive insulating ABS composite material and a preparation method thereof. Background technique [0002] With the development of electronic technology, the miniaturization and intensification of products have become a trend. Especially in the fields of communication, microwave, aerospace, smart phones, etc., the operating frequency of the system is gradually increasing, and the processing capability of the chip is gradually improving. How to improve the signal sensitivity, reliability and heat dissipation of the electronic system has become a hot spot. Electronic and electrical equipment will generate a lot of heat. If the heat cannot be discharged in time, it will inevitably cause damage to the components of electronic and electrical appliances and the equipment itself if it accumulates to a certain extent. Therefore, the excess heat...
