Example Embodiment
[0036] Example 1
[0037] A method for preparing the antistatic high-efficiency low-smoke halogen-free flame-retardant thermoplastic elastomer, including the following steps:
[0038] 1) Prepare various raw materials according to the weight percentage composition described in Table 1, where the antistatic agent is a 1:1 mixture of sodium dodecyl sulfonate and ethoxylated C12-14 tertiary alkylamine;
[0039] 2) After mixing the styrene elastomer and the filler oil and stirring it evenly, let it stand for 8 hours;
[0040] 3) Add other raw materials and stir for 3 minutes to make the raw materials evenly mixed and discharge;
[0041] 4) Put the mixed raw materials into a twin-screw extruder for extruding and granulation. The speed of the screw machine is 400r / min, the processing temperature is 200℃, and the extrusion granulation is the final antistatic, high-efficiency halogen-free Flame retardant thermoplastic elastomer.

Example Embodiment
[0048] Example 3
[0049] A method for preparing the antistatic high-efficiency low-smoke halogen-free flame-retardant thermoplastic elastomer, including the following steps:
[0050] 1) Prepare various raw materials according to the weight percentage composition recorded in Table 1, where the antistatic agent is a 1:1 mixture of sodium diethyldithiocarbamate and ethoxylauramide;
[0051] 2) After mixing the styrene elastomer and the filler oil and stirring it evenly, let it stand for 8 hours;
[0052] 3) Add other raw materials and stir for 3 minutes to make the raw materials evenly mixed and discharge;
[0053] 4) Put the mixed raw materials into a twin-screw extruder for extruding and granulation. The speed of the screw machine is 400r / min, the processing temperature is 200℃, and the extrusion granulation is the final antistatic, high-efficiency halogen-free Flame retardant thermoplastic elastomer.
