요약
에틸렌-프로필렌 디엔 단량체/폴리프로필렌에 바탕을 둔 에틸렌-프로필렌 디엔 단량체, 폴리프로필렌, 산화아연, 스테아르산, 그리고 클레이의 효과에 대하여 연소성을 조사하였다. 에틸렌-프로필렌 디엔 단량체/폴리프로필렌/클레이 나노복합체는 성형 후 콘칼로리미터(ISO 5660-1)를 이용하여 연소시험을 하였다. 그 결과 나노복합체는 에틸렌-프로필렌 디엔 단량체/폴리프로필렌 단독 조성에 비하여 최대열방출률을 감소시켰다. 이에 반하여 고무 연화제로 사용된 스테아르산은 자체의 연소성에 의하여 평균열방출률을 증가시켰다.
Abstract
Effects of ethylene-propylene diene monomer (EPDM)/polypropylene (PP), zinc oxide, stearic acid, and clay on the combustive properties based on EPDM/PP were investigated. The EPDM/PP/clay nanocomposites was compounded to prepare specimen for combustive analysis by cone calorimeter (ISO 5660-1). It was found that the combustive properties in the nanocomposites decreased due to the fire resistance compared with unfilld EDPM/PP. The nanocomposites showed the lower peak heat release rate (PHRR) than that of virgin EPDM/PP, while stearic acid for softening ruber increased the mean heat release rate (MHRR) by itself, combustible.
Key Words: Clay nanocomposites, Combustive properties, Peak heat release rate (PHRR)
