Abstract

The invention relates to a preparation method of a polypropylene rod and post-processing equipment for the preparation method. A polypropylene composition is subjected to extrusion molding by extrusion equipment, cut by cutting equipment and subjected to post-processing by the post-processing equipment to obtain the polypropylene rod; polypropylene of which the molecular weight is 3000 to 4000, thiocyano-1-(2-aminophenyl) ethanone, a flame retardant filler, an auxiliary filler and a melting index regulator are mixed to obtain the polypropylene composition; three independent devices, namely a heating device, a cooling buffer device and a cooling device, are arranged in sequence to form the post-processing equipment. The preparation method disclosed by the invention is wide in raw material source and simple and controllable in preparation process, only requires normal operation of the post-processing equipment, and further realizes continuous production of rod forming, cutting and post-processing for the first time, thereby being liable to industrialization.
