Abstract

In this research, magnesium hydroxide as a flame retardant agents and zinc borate as a synergist were mixed with LDPF/EVA blended samples, in order to improve their flame retardancy. We attempted to select the best mixing ratio of the LDPF/EVA blend and the optimum amount of magnesium hydroxide and zinc borate by the comparison and analysis of the flame retardancy, the electrical properties such as the volume resistivity and dielectric loss tangent, and the mechanical properties such as the tensile strength and elongation at break. Particularly, specimen which is the 6phr of zinc borate and 10phr of magnesium hydroxide 70/30phr adding to the LDPF/EVA blended samples has been most excellent in flame retardancy and electrical/mechanical properties.

본 연구에서는 저밀도 폴리에틸렌과 에털렌 비닐 아세테이트 블렌드(LDPF/EVA)의 난연성을 향상시키기 위해 난연제인 수산화 마그네슘과 난연상승보조제인 zinc borate를 첨가한 후, 난연성과 체적저항률, 유전정접, 교류 절연파괴강도 등의 전기적 특성, 인장강도 및 연신율 등의 가계적 특성을 비교 분석하여 가장 우수한 LDPF/EVA 블렌드의 혼합비 및 적절한 $Mg(OH)_2$의 zinc borate의 첨가량을 선정하고자 하였다. 혼합비 70/30phr의 LDPF/EVA 블렌드에 10phr의 $Mg(OH)_2$와 6phr 정도의 zinc borate를 첨가한 시편에서 가장 우수한 난연성 및 전기/기계적 특성을 나타내었다.
