A plastic pipe. The plastic pipe consists of the following components measured by weight: 60 to 80 parts of ultra low density polyethylene, 20 to 40 parts of ethylene propylene rubber, 5 to 8 parts of dimethyl silicon oil, 4 to 10 parts of antioxidant, and 4 to 8 parts of color masterbatch. The range of the viscosity of the dimethyl silicon oil is 5000-30000 cst. The antioxidant is one or more of the following materials: N-phenyl-α-naphthylamine, N-phenyl-β-naphthylamine, 2-mercaptan benzimidazole, and 2-mercaptan benzimidazole zinc salt. The color masterbatch is a mixture of the ultra low density polyethylene and a toner. The present invention has good insulation performance and a long service life, and facilitates construction. |
