Abstract

The aim of this paper is to analyze combustion characteristics of treated woods by fire retardants which are prepared by several borate and phosphate compound solutions. The combustion characteristics for flame retardant treated wood were carried out using thermogravimetric analysis (TGA) to measure their combustion heat and flame retardant test using cone-calorimeter. The result of TGA and flame retardant test showed that single chemical solution affected the char forming and flame delay. The mixed retardants solutions was believed to be related to the efficacy and property of single chemical. The retention value and concentration of the retardants also affected the performance of fire retardant treated woods. The fire retardants FR1 and FR2 satisfied the requirement of The 3 Grade of Korean building codes.

본 연구는 목재에 난연성능을 부여하기 위한 난연제 조성물을 제조하고 그 난연제를 처리한 목재의 난연성능을 평가함에 있다. 난연제 조성물은 단독 혹은 혼합하여 소나무에 처리한 후 열분해 특성을 분석하였다. 처리된 시료의 연소특성 분석에는 TGA와 콘칼로리미터를 사용하였다. 시험결과, 단독약제에 의한 TGA의 열적 거동은 목재에 처리 시 Char의 형성 및 연소 지연 등으로 표현되어 나타났으며 이러한 연소특성은 이후 약제의 혼합에 의한 조성물의 난연성능의 발현에 영향을 미쳤다. 혼합약제의 목재 처리 후 콘칼로리미터에 의한 열특성 분석에서는 처리농도 및 처리량에 따라서 열방출률 및 총열방출량에 영향이 있었다. 난연제 조성물 중 FR1, FR2는 건축법 난연 3급을 만족하였다.
