Abstract

본 발명은 에틸렌 함량이 27~44몰%인 에틸렌-비닐알코올공중합체 30~70중량%와 지방족 폴리에스터 공중합체 30~70중량%로 구성되는 합성수지 35~75중량%와 전분 25~65중량%를 주성분으로 하며, 수지 가소제를 전체수지 조성에 대하여 1~5중량% 첨가하고, 전분함량에 대하여 수분을 15~45중량% 첨가한 후 고압에서 전분입자를 파괴하여 용융, 혼련하는 것을 특징으로 하는 생분해성 수지의 제조방법에 관한 것이다.The present invention is composed of 35 to 75% by weight of synthetic resin consisting of 30 to 70% by weight of ethylene-vinyl alcohol copolymer having an ethylene content of 27 to 44 mol% and 30 to 70% by weight of aliphatic polyester copolymer and 25 to 65% by weight of starch. Its main component, 1 to 5% by weight of the resin plasticizer is added to the total resin composition, 15 to 45% by weight of water relative to the starch content, and then melted and kneaded by breaking the starch particles at high pressure It relates to a method for producing a biodegradable resin.
