Embodiment 1
[0021] The carbon-carbon / rubber composite material preparation method involved in this embodiment is also called the atomization drying method, and its process includes three steps of preparing masterbatch mixture, preparing masterbatch and preparing composite materials:
[0022] (1) Preparation of masterbatch mixture:
[0023] First prepare the carbon-carbon composite material aqueous solution: the carbon-carbon composite material powder and water are sonicated for 15min-12h at a temperature of 25-100°C and a power of 500-1500W to prepare a carbon-carbon composite material aqueous solution;
[0024] Then prepare the carbon black slurry: mix and stir the water and carbon black of the set mass fraction, and process it with a high-speed disperser to obtain a uniformly dispersed carbon black water dispersion with a mass percentage concentration of 20-30%. Treat the carbon black aqueous dispersion with a ball mill for 4-6 hours to obtain a carbon black slurry;
[0025] Finally, p...
