The invention relates to an environment-friendly antibacterial PP plastic and a preparation process thereof, belonging to the technical field of polymer materials. The preparation steps comprise pretreatment of PP powder, stirring the pretreated PP powder, antibacterial agent, white oil and stabilizer in a high-speed mixer to obtain a mixed raw material, feeding the mixed raw material into a twin-screw extruder for melt extrusion, cold drawing and pelletizing, and injection molding to prepare samples. The antibacterial agent is a mixture of polylysine hydrochloride, polylysine citrate and natamycin, and the stabilizer is a mixture of any one of 2,6-di-tert-butyl-4-methylphenol, bis(3,5-di-tert-butyl-4-hydroxyphenyl) sulfide, pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate] and phosphite. The production formula and preparation process provided by the invention avoid the problem of environmental pollution by toxic substances easily produced by the solution grafting method, overcome the problem of reduced product strength easily caused by the existing melting method, and have good antibacterial properties.
