Example Embodiment
[0036] Embodiment 1: its raw material ratio is as follows (unit: weight part):
[0037]
[0038] Its manufacturing method is as follows:
[0039] First, the polyester polyol (polycarbonate polyol) and isocyanate (hexamethylene diisocyanate) were baked at 70°C for 8h; triethylenediamine and stannous octoate, water, 1,4-butanediol were baked , polysiloxane-polyalkoxy ether copolymer, two-dodecylamine polyoxyethylene ether triquaternary ammonium salt and carbon fiber powder are added to the baked polyol (polycarbonate polyol), and stir evenly to form A Finally, the material A and the baked raw material B isocyanate (hexamethylene diisocyanate) are mixed and cast to form, and the polyurethane sole is prepared by curing for 3 minutes. See Table 1 for the volume resistance value and bending resistance of the material in this example.
Example Embodiment
[0040] Embodiment 2: its raw material ratio is as follows (unit: weight part):
[0041]
[0042] Its manufacturing method is as follows:
[0043]Bake polyether polyol (polytetrahydrofuran ether diol) and isocyanate (diphenylmethane diisocyanate) at 70°C for 8h; next, bake triethylenediamine and stannous octoate, water, glycerol, polysiloxane Alkane-polyalkoxy ether copolymer, octadecylamine polyoxyethylene ether diquaternary ammonium salt and carbon fiber powder are added to the baked polyol (polytetrahydrofuran ether diol), stirred evenly to form A material; The material A and the baked raw material B isocyanate (diphenylmethane diisocyanate) are mixed and cast to form, and the polyurethane sole is prepared by curing for 3 minutes. See Table 1 for the volume resistance value and bending resistance of the material in this example.
Example Embodiment
[0048] Embodiment 3: its raw material ratio is as follows (unit: weight part):
[0049]
[0050] Its manufacturing method is as follows:
[0051] Firstly, polyester polyol (polycarbonate polyol) and isocyanate (diphenylmethane diisocyanate) were baked at 70°C for 8h; secondly, triethylenediamine and stannous octoate, water, 1,4-butanedi Add alcohol, polysiloxane-polyalkoxy ether copolymer, didodecylamine polyoxyethylene ether triquaternary ammonium salt and carbon fiber powder into the baked polyol (polycarbonate polyol), stir evenly to form Material A; finally, the material A and the baked raw material B isocyanate (diphenylmethane diisocyanate) are mixed and cast to form, and the polyurethane sole is prepared by curing for 3 minutes. See Table 1 for the volume resistance value and bending resistance of the material in this example.
