Semi-conductive compound composition and method for preparing same

A semiconducting compound composition comprising:

• a base resin obtained by mixing two types of ethylene butyl acrylate resins having different melt indices, the two types of ethylene butyl acrylate resins being a first ethylene butyl acrylate resin and a second ethylene butyl acrylate resin;
• and
• carbon black,
• wherein in the base resin, the first ethylene butyl acrylate resin is an ethylene butyl acrylate resin having a content of a structural unit derived from a butyl acrylate monomer of 15 to 18 mol % and having MI1 of 5 to 10 g/10 min,
• the second ethylene butyl acrylate resin is an ethylene butyl acrylate resin having a content of a structural unit derived from a butyl acrylate monomer of 19 to 22 mol % and having MI2 of 17 to 22 g/10 min, and
• wherein a content of the carbon black satisfies the following Expression 1:
