Example Embodiment
[0052] Example 1
[0053] A high thermal conductivity silicone rubber cable material, which comprises the following components according to parts by weight:
[0054]
[0055] Its preparation method comprises the following steps:
[0056] (1) methyl vinyl silicone rubber, magnesium hydroxide, aluminum hydroxide, polydopamine-modified graphene (mix dopamine and graphene with a mass ratio of 1:1 in deionized water at 50° C. for 2 hours to obtain the Polydopamine modified graphene), boron nitride, compatibilizer, stabilizer, silicone masterbatch, silane coupling agent and antioxidant were mixed at 160°C for 25min, and then pelletized by a single-screw extruder. The single-screw extruder includes the first zone, the second zone, the third zone, the fourth zone, the fifth zone, the sixth zone and the seventh zone. The material passes through each zone in sequence, and the working temperature of the first zone is set as 110℃, the working temperature of the second zone is 115℃, t...
