technical field [0001] The invention relates to the technical field of interconnection dielectric materials for integrated circuits, in particular to a thermoplastic resin composition with high thermal conductivity and high insulation, a preparation method and application thereof. Background technique [0002] With the rapid development of microelectronic high-density assembly technology and integration technology, the assembly density of electronic equipment has been rapidly increased, making electronic components and logic circuits smaller by tens of millions of times. At this time, the heat generated by electronic equipment will increase sharply. , and at the ambient temperature, composite insulating materials with high thermal conductivity are extremely important to make electronic components work normally with high reliability.

Problems solved by technology

[0004] In addition, at present, the bonding between the layers of circuit boards in the existing electronics industry uses thermosetting insulating adhesive films, which require a relatively long curing time and have relatively high requirements for storage conditions (usually low temperature and low humidity and other demanding conditions are required. ), which is inconvenient to use; in addition, the thermal conductivity of the system formula used is poor, resulting in the thermal conductivity of the film generally not exceeding 0.2W / (m K), which limits its scope of use
