상용화제 첨가가 화이트 바이오 생분해 플라스틱 필름의 인장강도와 토출 량과 비중에 미치는 영향 Effects on the Tensile Strength and Discharge Volume of the White Biodegradable Plastic film added Compatibilizer원문보기
우리나라가 1인당 플라스틱 년간 소비량이 132 kg(2019)으로 세계1위로 나타났고, 지구온난화와 탄소중립을 위한 국제적 협약이 진해되고 있으며 소비자들도 바이오플라스틱에 대한 관심과 니즈가 증가하고 있어, 바이오플라스틱 소재에 복합 사용화 첨가제를 농도별로 첨가하여 필름을 생산 시 토출량, 용융지수, 인장강도 변화를 조사하였다. 석유계 수지인 LLDPE와 LDPE보다 PLA와 PBAT에서 용융지수가 현저히 높은 것으로 나타났으며 동일 수지나 동일 처리구에서는 heating temperature가 증가함에 따라 용융지수가 증가한 것으로 나타났다. 상용화제 4%를 첨가한 BDP-2 처리구에서 토출양도 비중도 우수한 것으로 조사되었으며, MD 및 TD 방향의 인장강도도 높게 나타나 BDP-2가 복합화 생분해 필름 제조용 제조 방법으로 가장 적합한 것으로 사료되었다.

Today, plastic waste has become a critical social issue due to the increasing of plastic consumption. Korean annual per capita plastic consumption was 132 kg, the most plastic consuming country in the world. Internationally, Carbon Neutral Agreement is underway due to global warming, consumers' interest and needs for biomass-based plastics has also been increased. In this study, film was produced by adding composite use additives to the biomass-based plastics according to concentration, and the resulting changes in discharge volume, melt index, and tensile strength were investigated. Melt index (MI) was significantly higher in PLA and PBAT than in petroleum-based resin LLDPE and LDPE. Also, among the same resin or in the same treatment group, MI has been increased when the heating temperature is increased. The discharge volume and gravity of the BDP-2 to which 4% compatibilizer was added were found to be higher among all treatments, while the tensile strength of MD and TD was also higher. BDP-2 was suitable to the film producing methods for biodegradable film production.
