The invention discloses antibacterial polyvinyl chloride resin, and belongs to the technical field of resin preparation. The antibacterial polyvinyl chloride resin is prepared from polyvinyl chlorideresin, polylactic acid, organic fluorine epoxy resin, polyphenylene sulfide, polycarbonate, polyhydroxybutyrate, vinyl acetate, calcium molybdate, chitosan, zinc borate, kieselguhr, wood fiber powder,chlorinated paraffin, polyethylene glycol, trioctyl trimellitate, polycaprolactone, trimethyl phosphate, tributyl citrate, adipic dihydrazide, tartaric acid, potassium peroxodisulfate, zinc phosphate, fluorine micro powder, nanometer titania, a silane coupling agent KH-560 and antibacterial performance additives. The antibacterial polyvinyl chloride resin is prepared through the steps of preparing a base material, preparing a modified material, mixing the base material, the modified material and other materials and the like. The prepared polyvinyl chloride resin has the excellent antibacterial performance.
