1. a kind of preparation method of superhigh molecular weight polyethylene fibers, it is characterised in that comprise the following steps:

  • (1) super high molecular weight polyethylene gel precursor is obtained using gel spinning legal system;

    (2) by the super high molecular weight polyethylene gel precursor of step (1) through balancing stewing process;

    (3) and then by the super high molecular weight polyethylene gel precursor that step (2) is balanced after stewing process preliminary draft, extraction are carried out successivelyTake, dry and be not less than the hot gas spring of three-level, and while hot gas spring, pass through super high molecular weight polyethylene gel precursorCross the application roll with the antistatic additive aqueous solution;

    (4) dry, obtain final product superhigh molecular weight polyethylene fibers;

    Wherein, the mass concentration of the antistatic additive aqueous solution is 0.2~0.8%, and the antistatic additive is by alkylating reagentWith quaternary ammonium salt cationic highly effective antistatic agent obtained by fatty amine reaction, kinematic viscosity of the antistatic additive at 40 DEG C is 15~20mPa.s.
