[0003] Chinese Invention Patent Application Publication No. CN106243620B discloses a polyether ether ketone thermally conductive composite material and its preparation method and application. Fillers with different thermal conductivity are added to polyetheretherketone to prepare the composite material. Although the thermal conductivity is significantly improved, the Its mechanical properties such as impact strength are significantly reduced due to the addition of small molecule fillers, which limits its application to a certain extent.
[0004] In summary, in the prior art, it is difficult to produce a polyether ether ketone resin with excellent mechanical properties and high thermal conductivity, so a high thermal conductivity polyether ether ketone resin is proposed

Description

technical field [0001] The invention relates to the technical field of heat-conducting resins, in particular to a high-heat-conducting polyetheretherketone resin and molded products thereof. Background technique [0002] In recent years, traditional thermal conductivity materials have been difficult to meet people's needs in use. With the rapid development of special engineering materials, research on high thermal conductivity engineering materials has attracted much attention. Polyether ether ketone (PEEK) resin is the most typical material in polyarylether ketone (PAEK). It is a kind of thermoplastic engineering plastic with excellent comprehensive performance in recent years, high temperature resistance, chemical resistance and excellent rigidity and toughness. It has been gradually applied In aerospace, automotive, energy and other fields. However, single-component polyether ether ketone has poor performance in terms of thermal performance and antistatic performance, wh...
