The present invention relates to an eco-friendly functional filler for artificial turf for having excellent impact absorbing properties and permeability and preventing the loss of filler using an eco-friendly biodegradable polymer. The eco-friendly functional filler for artificial turf is formed by extruding and injecting a mixture of 40 to 60 wt% of a biodegradable polymer, 20 to 30 wt% of red clay powder which is a mineral filler, 15 to 30 wt% of crushed straws, and 0.01 to 5 wt% of stabilizer which is addition agent. The biodegradable polymer is formed by blending at least one of a natural polymer having starch, chitin, or cellulous, synthetic polymers having polycaprolactone (PCL), polylactic acid (PLA), aliphatic polyester, or polyglycolic acid (PGA), and microbial polymers having polyhydroxyalkanoates (PHA) or poly-3-hydroxy-butyrate. The red clay powder has a particle size of 300 mesh or more. The crushed straw has a size of 0.1 to 1 mm. The stabilizer is mixed of one or more of a group consisting of a heat stabilizer, an antioxidant, and an UV stabilizer. |
