Description

Technical field: [0001] The invention relates to the technical field of insulating and heat-conducting materials, in particular to an insulating and heat-conducting plastic with high mechanical strength. Background technique: [0002] In the field of electronic technology, due to the increasing integration of electronic circuits, the accumulation of heat is increasing. The accumulation of heat causes the temperature of the device to rise and the working stability to decrease. According to the Arhennius formula, for every 10°C increase in temperature, the life of the processor is reduced by half. Therefore, the material used for the processor is required to have high thermal conductivity, so that the heat can be conducted out quickly to achieve the purpose of cooling. For highly integrated chips, the design heat energy is so high that it is difficult for ordinary heat sinks to ensure effective heat dissipation. For devices that require insulation and heat dissipation, high ...
