Abstract:
본 발명은 바이오 플라스틱 조성물 및 이를 이용한 부직포에 관한 것으로, 보다 상세하게는 L-폴리락트산 수지, D-폴리락트산 수지와 폴리히드록시 알카노에이트 수지가 혼합된 블렌드(Blend) 수지를 포함하는 바이오 플라스틱 조성물 및 이를 성형하여 제조된 부직포에 관한 것이다. 본 발명에 의한 바이오 플라스틱 조성물은 수지 성분 간의 상용성 문제로 인하여 발생하는 물성 저하를 해결하였기 때문에, 생분해성, 유연성 및 기계적 물성이 우수하다. 또한 폴리락트산의 스테레오컴플렉스의 형성으로 인하여 열적 특성이 크게 개선될 수 있다. 특히 상기 조성물로 제조된 부직포의 경우 내열성 및 강도가 매우 우수하므로 자동차 내장재로서 적용되는 경우 경량화 및 친환경 컨셉이 주를 이루는 현 자동차 시장의 트렌드에 부합할 수 있을 것으로 기대된다.

Abstract:
PURPOSE: A bioplastic composition is provided to improve flexibility, chemical resistance, and heat resistance by solving a compatibility problem between biodecomposable resins comprising bioplastics. CONSTITUTION: A bioplastic composition comprises a blend resin which is formed by mixing a polylactic acid resin and a polyhydroxyalkanoate resin. The polyhydroxyalkanoate resin comprises a repetitive unit represented by chemical formula 1. In chemical formula 1, R1 is a hydrogen atom, or a substituted or a non-substituted C1-15 alkyl group, and n is an integer of 1 or 2. In the blend resin, the content of the polylactic acid resin is more than the content of the polyhydroxyalkanoate resin.
Abstract:
PURPOSE: An acrylic laminate film is provided to have excellent weatherability, moldability, and transparency and to improve cloudiness resistance and film formation and to prevent cloudiness at processing and degradation of transparency. CONSTITUTION: An acrylic laminate film comprises 30-60 wt% of a granular acrylic rubber copolymer which consists of a multistructure of a core and shell; 70-40 wt% of a bead phase acrylic thermoplastic resin. A manufacturing method of an acrylic laminate film comprises a step of forming the granular acrylic rubber copolymer; a step of forming a bead phase acrylic thermoplastic resin; and a step of forming a bead phase thermoplastic resin; a step of forming a resin mixture by mixing the granular acrylic rubber copolymer and bead phase thermoplastic resin; and a step of melting the resin mixture to mold the melted material.
