Antistatic PET (Polyethylene Terephthalate) composition as well as preparation method and application thereof

The invention discloses an antistatic PET (Polyethylene Terephthalate) composition which comprises the following components in parts by weight: 70-85 parts of PET resin; 8-32 parts of conductive carbon black; 0.1 to 3 parts of a carbon nano tube; 0.5 to 5 parts of alkyl glycidyl ether; and 0.5 to 2.5 parts of silicone. According to the invention, a certain amount of carbon nanotubes, alkyl glycidyl ether and silicone are added into a conductive carbon black filled PET material system and cooperate with each other, so that the conductivity and resistance stability of the material are significantly improved, and after stretching processing, the antistatic PET material can still maintain good antistatic performance and effectively reduce shedding of carbon black on the surface of the material at the same time; the problems that the resistance of the conductive carbon black filled PET material is greatly increased and the carbon black is easy to fall off due to stretching processing in the prior art are well solv
