The present invention relates to a biodegradable foam buoy. More particularly, the present invention relates to a biodegradable foam buoy that can be naturally decomposed in water even if lost or damaged by foaming the biodegradable polymer, thereby protecting the marine environment. According to the present invention, the biodegradable foam buoy comprises a foam body formed by foaming a resin composition containing 70 to 90 wt% of polylactic acid (PLA), 5 to 25 wt% of polybutylene adipate terephthalate (PBAT), and 1 to 5 wt% of diglycidyl ether of bisphenol-A (DGEBA).
본 발명은 생분해성 발포 부구에 관한 것으로서, 더욱 상세하게는 생분해성 고분자를 발포시켜 제조함으로써 유실 또는 파손되더라도 수중에서 자연분해가 가능하여 해양환경을 보호할 수 있는 생분해성 발포 부구에 관한 것이다. 본 발명의 생분해성 발포 부구는 폴리락트산(PLA) 70 내지 90중량%와 폴리부틸렌아디페이트테레프탈레이트(PBAT) 5 내지 25중량%, 비스페놀-A의 디글리시딜 에테르(DGEBA) 1 내지 5중량%를 함유하는 수지 조성물을 발포시켜 형성한 발포체를 포함한다.
