PURPOSE: A PVC pipe of an antimicrobial triple structure is provided to improve impact resistance and strength against impact, and to stably and sanitarily supply drinking water using a water pipe with antimicrobial ability. CONSTITUTION: A PVC pipe of an antimicrobial triple structure is composed of an external layer(1), a central layer(2), and an internal layer(3). The external layer and the internal layer are composed of composite heat stabilizer 2~6 weight%, Methyl Methacrylate-Butadiene-Styrene impact modifier 3~8 weight%, zeolite 1~3 weight%, vermiculite 1~8 weight%, phosphate compound 0.1~2 weight%, lubricant 0.2~3 weight%, and TiO2 0.5~2 weight%. The central layer is composed of composite heat stabilizer 2~6 weight%, Methyl Methacrylate-Butadiene-Styrene impact modifier 0~2 weight%, CaCO3 0.1~5 weight%, lubricant 0.2~3 weight%, and TiO2 0.5~2 weight%.
