Description

[0001] technical field [0002] The invention relates to the field of polymer material modification, in particular to a polyphenylene sulfide composite material and a preparation method thereof. Background technique [0003] At present, the heat dissipation devices commonly used in general industries are mainly metal materials with excellent thermal conductivity, but metal materials have poor corrosion resistance, are difficult to process, have a large specific weight, and are relatively expensive; in recent years, research on plastic strip steel It has attracted much attention. The research on thermal conductivity and electrical conductivity of plastics has continued to develop. It mainly uses conventional thermal and conductive fillers such as metal powder or thermal graphite, and the thermal conductivity of polymers is good, but the relative performance of other properties has dropped a lot, especially the impact. toughness. [0004] For example, CN102464883A discloses ...
