The invention belongs to the technical field of pipe materials, and particularly relates to granules special for a high-toughness conductive polypropylene pipe fitting and a preparation method of the granules. The special aggregate for the high-toughness conductive polypropylene pipe fitting is prepared from the following components in parts by mass: 80-100 parts of polypropylene resin, 10-30 parts of a thermoplastic elastomer blend, 3-5 parts of a coupling agent, 2-3 parts of a dispersing agent, 3-5 parts of extending oil, 10-20 parts of carbon nanotubes and 10-20 parts of conductive carbon black. According to the formula, the carbon nano tube and the conductive carbon black are mixed to serve as a conductive medium, an efficient conductive system can be formed, the thermoplastic elastomer is subjected to oil-filled blending, the toughness of the material can be improved while the conductive effect is not affected, and therefore the problems that an existing polypropylene pipe fitting is unstable in conducti
