Environmentally friendly antimicrobial and mildew resistant synthetic fillers for artificial turf including antimicrobial polyurethane microcapsules and their preparation

摘要

The present invention relates to an antimicrobial and antifungal elastic filler and a method for manufacturing the same. More particularly, the present invention relates to an elastic filler for artificial turf, which has an antimicrobial agent and antifungal properties on an elastic chip, and a method for manufacturing the same. The present invention provides a method for manufacturing an antimicrobial and antifungal elastic chip, characterized in that a surface of a regenerated or new rubber ship is coated by mixing a polyurethane microcapsule containing chitosan, a pigment and a polyurethane binder, followed by curing. In the antimicrobial and antifungal elastic chip according to the present invention, the chitosan acts as an antimicrobial material and is usable with the polyurethane binder, so that a separate material such as expanded graphite is not required.
