Abstract

Nowadays, awareness towards environmental issues increases significantly where people have learned the important of protecting environment for a better future. Thus, this study have explore the kenaf fiber embedded with fire retardant liquid by producing a heat and fire insulator application. The samples is 200 mm x 2000 mm x 40 mm in size, with fixed composition of kenaf fiber but different fire retardant ratios. The sample is prepared by combining 184g kenaf fiber with 5% of fire retardant and gradually increasing the amount of fire retardant until 25%. It take approximately one hour for the kenaf fiber and fire retardant mixture to completely mixed. The samples are then dried for 2 to 3 days at room temperature with good ventilation surrounding. Thermal testing, fire testing and acoustic testing have been performed as part of this study. The outcome of this study is that the performance of sample as a good insulator depends in the composition ratios of fire retardant and also the density of the sample. The use of kenaf fiber embedded with fire retardant is to produced an excellent performance of heat and fire insulators.As a result, sample S1 with the highest value of thermal conductivity which is 0.4472 W/mK and temperature different of 240°C, sample S6 with the higher percentage of non-burn fiber which is 98.103% and lastly, sample S3 which have reached the highest peak of 0.9104 coefficient at 1259 Hz and at 1600 Hz with coefficient of 0.9091 was obtained. This study suggest that this study sample have a potential to replace the current insulator used in industry.
