It is 0.1%, the sn-bi alloy, terne metal grain size are 20~30 μm；Also contain calcium carbonate, the carbon in the composite fibre
Sour calcium content is 0.6wt%；
The making step of the composite fibre is as follows：
Step 1, multi-walled carbon nanotube processing：
First, compound concentration 10- 4M chloroplatinic acids and a concentration of 10- 5The reaction solution of M polyvinylpyrrolidones, to reaction solution
In be passed through high-purity argon gas bubbling 30min, remove the oxygen in liquid, be then equally passed through hydrogen 10min and restored, then will
Reaction solution sealing, which is protected from light, stands 12h, and in the reaction system, the platinum grain growth of 5nm or so obtains platinum grain suspension；
The multi-walled carbon nanotube of purchase is taken, length is 50~500 μm, more than 1h in above-mentioned suspension is dipped into, due to platinum
Particle is 5nm or so, and grain size is smaller, and platinum grain can be embedded in surface or the fault location of multi-walled carbon nanotube；
Step 2 prepares mixture：
By sn-bi alloy, terne metal, carbon nanotube, antioxidant 1010, antioxidant 168, zinc stearate, calcium carbonate and gather
Propylene pellet is uniformly mixed by proportioning in homogenizer, then with extruder extruding pelletization, obtains compound particles；
Wherein, antioxidant 1010 content is 0.1wt%, and 168 content of antioxidant is 0.1wt%, and zinc stearate content is
0.25wt%, calcium carbonate content 0.6wt%；
Step 3 prepares precursor：
Said mixture particle at 80 DEG C is dried into 4h, is then precursor by its spinning using capillary rheometer；
Step 4 prepares anti-electrostatic polymer composite material：
Upper step is obtained into precursor and makes annealing treatment 5h at 180 DEG C, then Uniform Tension, extends 5~20 with 10mm/min speed tensiles
Times, obtain the anti-electrostatic polymer composite fibre.
2. according to claim 1 securely transmit band, which is characterized in that the anti-electrostatic polymer composite fibre with it is anti-quiet
Current source contacts, and the antistatic chain other end is contacted with the earth.
