Examples
Embodiment 1
[0020] (1) Preparation of UHMWPE charged particles: UHMWPE was dried in a vacuum oven at 100°C for 24 hours, so that the moisture content in the UHMWPE raw material was lower than 0.01%. Put 10g of UHMWPE and 10mg of graphene in a high-speed mixer and stir to obtain ultra-high molecular weight polyethylene / graphene composite particles; among them, graphene was added to the high-speed mixer in 3 times, each time stirring at a speed of 10000r / min for 10s at a high speed.
[0021] (2) High-temperature compression molding: preheat the ultra-high molecular weight polyethylene / graphene composite particles prepared in step (1) at 200°C for 5 minutes; then hot-press at 200°C and 10MPa for 30 minutes; finally cool to At room temperature, the target product was prepared.
Embodiment 2
[0023] Others are the same as in Example 1, the added graphene content is 50 mg, and the number of times of high-speed stirring is 5 times.
Embodiment 3
[0025] Others are the same as in Example 1, the added graphene content is 100 mg, the number of high-speed stirring is 10 times, and 10 mg graphene is added each time.
