FILLING METERIAL FOR ARTIFICIAL GRASS MANUFACTURING APPARATUS AND METHOD OF FILLING METERIAL FOR ARTIFICIAL GRASS

摘要

Provided is a method for producing a filling material for artificial turf, comprising the following steps: an ingredient mixing step for mixing ethylene propylene diene terpolymer (EPDM), a filler, a heavy metal neutralizer, and a vulcanizer; an ingredient molding step for molding the ingredient mixture in a form of chips; a step for collecting the molded product using a water pump and then removing remaining moisture; a primary vulcanization step for conducting vulcanization only by hot air while pressure is not applied to the filling material molded in the form of chips; and a secondary vulcanization step for conducting secondary vulcanization after the primary vulcanization is completed.
