Graphene composite ultra-high molecular weight polyethylene fiber and preparation method thereof

A method for preparing a composite ultra-high molecular weight polyethylene fiber, comprising:

• preparing a glass fiber premix:
• dispersing glass fiber in a first white oil to obtain the glass fiber premix containing 5 wt % to 30 wt % of glass fiber;
• preparing a graphene slurry premix:
• grinding graphene slurry, filtering, then adding the filter residue to a second white oil, and then adding a first UHMWPE to the second white oil containing the graphene filter residue, heating the premix to a first temperature, raising the first temperature to a second temperature after the same was not bubbled, and maintaining the second temperature;
• preparing a spinning mixture:
• mixing the glass fiber premix, the graphene slurry premix, a second UHMWPE, an antioxidant, and a third white oil to obtain the spinning mixture;
• swelling and mixing the spinning mixture to form a molten state;
• extruding the spinning mixture which is in the molten state;
• cooling to form a gel-spun;
• and
• obtaining the composite ultra-high molecular weight polyethylene fiber from the gel-spun.
