[0017] Example 1
[0018] An antistatic modified PBT fiber, made of the following components by mass:
[0019] 45 parts of terephthalic acid, 43 parts of butanediol, 0.5 parts of tetraethyl titanate, 8 parts of modified graphene, zinc oxide and zirconium oxide with a particle size of 50-100nm in a mass ratio of 1:1. 3 parts of compound, 0.1 part of antioxidant 1010, 0.4 part of triphenyl phosphite.
[0020] Among them, the modified graphene is prepared as follows: 1) Graphene vulcanization: immerse graphene in concentrated sulfuric acid, heat it at 140-150℃ for 10-12h, take it out, filter and wash with distilled water for 3-6 times to obtain vulcanization Graphene; (2) Dissolve sulfurized graphene in anhydrous ethanol solvent, the concentration of sulfurized graphene in anhydrous ethanol is 3 to 5%, the pH of the ethanol solvent is controlled to 8.5, and then the silane coupling agent KH550 is added at the temperature The reaction is carried out at 35-45°C for 3-5h; (3) After the r...
