BIO-DEGRADABLE SYNTHETIC RESIN COMPOSITION IN WHICH BIODEGRADATION PROPERTY IS CONTROLLED AND A EROSION CONTROL MAT USING A FILAMENT AND THEREOF CAPABLE OF CONTROLLING SERVICE LIFE AND ENHANCING RIGIDITY, FLEXIBILITY, AND SHOCK RESISTNACE

摘要

PURPOSE: A bio-degradable synthetic resin composition in which biodegradation property is controlled and an erosion control mat using a filament and thereof are provided to control biodegradation and obtain thermal stability, workability, and property of matter.;CONSTITUTION: A bio-degradable synthetic resin composition in which biodegradation property comprises 0.1-5 parts by weight of compatibilizer, , and 0.1-2 parts by weight of talc, or 0.2-2 parts by weight of calcium carbonate or chain extender based on 100.0 parts by weight resin compound. The resin compound comprises 30-80 weight% of number average molecular weight, 54,970-78,370 weight% of polylactic acid, and 70-20 weight% of polymer resin. The polymer resin is a mixture of more than one or two types which is selected from a group consisting of poly(butylenes adipate)-co-butylene terephthalate, poly(butylene succinate), and copolyester.;COPYRIGHT KIPO 2012
