[0026] A kind of composite material preparation method of carbon nanotube provided by the invention comprises the following steps:
[0027] S1, weigh 100 parts of carbon nanotubes, 100 parts of NR, 3.5 parts of zinc oxide, 2.5 parts of stearic acid, 0.3 parts of anti-scorch agent, 1.5 parts of accelerator CBS, 15 parts of sulfur, and 50 parts of carbon black according to a certain weight ratio. parts and modified CNT S (2, 5, 9, 15) copies;
[0028] S2, respectively grind the carbon nanotubes and zinc oxide through a ball mill for standby. When performing ball milling, it needs to be carried out under the protective atmosphere of adding an inert gas, and the ball-to-material ratio is 10:2, the speed is 200r / min, and the forward rotation is 20min. Then pause for 30 minutes, and then reverse for 20 minutes, so that the cycle is carried out, and the cumulative ball milling is 3-4 hours;
[0029] S3, add the carbon nanotubes and zinc oxide in the above S2 to the HAKKE torque rhe...
