Abstract

This study has conducted an experiment of comparing the flame resistant performance and combustion characteristics according to flame resistant treatment using the Cypress Luba and particle board that is commonly used for interior decoration and furniture. As a result of testing the flame resistant performance of Cypress Luba, the Cypress Luba injected with flame resistant resin using the vacuum pressure treatment has shown to have better performances (carbonized area 9.55% and carbonized length 22.91%) than the Cypress Luba treated with flame resistant coating having rubberized plastic components on its surface. For particle board, the specimen attached with fireproof film was identified to be better (carbonized area 40.10% and carbonized length 43.40%) than the specimen with non-fireproof film. For the results of combustion characteristics using the Cone Calorimeter, the specimen treated with flame resistant coating on the surface had faster ignition than the Cypress Luba injected with fire resistant resin using vacuum pressure treatment, and in the total release of calories, the Cypress Luba injected with fire resistant resin using vacuum pressure had $68.2MJ/m^2$, and the specimen treated with fire resistant coating on the surface had $111.52MJ/m^2$. For the particle board, the ignition time had a little difference but in the total release of calories, the specimen attached with fireproof film had $90.1MJ/m^2$ and the specimen with non-fireproof film had $107.6MJ/m^2$.

본 연구에서는 실내장식 및 가구류 등에 이용되고 있는 편백루바와 파티클보드를 이용하여 방염처리 방법에 따른 방염성능 및 연소특성을 비교하는 실험을 하였다. 편백루바의 방염성능검사 결과 진공가압처리를 이용하여 난연수지를 주입한 편백루바가 표면에 염화고무수지 성분의 방염도료처리를 한 편백루바 보다 탄화면적은 9.55%, 탄화길이에서는 22.91% 우수한 것으로 나타났으며, 파티클보드는 파티클보드에 방염필름을 부착한 시편이 비방염필름을 부착한 시편보다 탄화면적 40.10%, 탄화길이에서는 43.40% 우수한 것으로 파악 되었다. Cone calorimeter를 이용한 연소특성 결과 편백루바 표면에 방염도료 처리를 한 시편이 진공가압처리를 이용한 난연수지 주입방식의 편백루바 보다 착화가 빨리 발생하였고, 총방출열량에서는 진공가압처리를 이용한 난연수지 주입방식의 편백루바가 $68.2MJ/m^2$, 편백루바 표면에 방염도료 처리를 한 시편이 $111.52MJ/m^2$을 나타내었으며, 파티클보드의 경우 착화시간에서는 미소한 차이를 보인 반면 총 방출열량에서는 파티클보드에 방염필름을 부착한 시편이 $90.1MJ/m^2$, 비방염필름을 부착한 시편은 $107.6MJ/m^2$의 총열방출량을 나타내었다.
