Eco-friendly polylactic acid based composite composition having a controlled physical property and preparation method thereof

摘要

The present invention relates to an environmentally friendly poly (lactic acid) composite material composition having controlled properties and a method for producing the same. The present invention can provide an eco-friendly composite material composition exhibiting physical properties capable of extrusion molding without compromising the environmental friendliness of the composite material composition in the production of a ternary eco-friendly composite material composition containing polylactic acid resin, natural rubber and organic clay . In the present invention, a process for producing a composite material composition, particularly by preliminarily selecting a content value of an organic clay, that is, a critical content value, from which the environmentally friendly composite material composition transitions from a soft property to a brittle property, It can be designed optimally.
