Embodiment Construction
[0028] In order to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with examples, which do not constitute any form of limitation to the present invention.
[0029] According to the raw material formulation scheme of each embodiment in Table 1, weigh according to the weight fraction, pretreat the heat conduction agent, add the heat conduction agent into the high-speed mixer in different proportions, perform silane coupling agent treatment, mix evenly, and set aside ; The carbon fiber short fiber is surface treated, and made into uniform particles with a binder; PPS, PPO, PA, toughening compatibilizer, thermal conductivity agent and other additives are added to a high-speed mixer and mixed uniformly; after mixing The material is extruded and granulated in a twin-screw extruder. The extruder is divided into 10 zones. The screw combination is the best combination that can obtain the maximum ther...
