Abstract: | Hidroksiapatit (HAp) merupakan senyawa anorganik yang tersusun atas
fosfor yang memiliki kemampuan dalam meningkatkan sifat ketahanan api.
Material ini didapat dari sintesis tulang ikan hasil samping pengolahan ikan tuna.
Penelitian ini bertujuan membuat dan menentukan karakteristik fire resistance
coating berbahan dasar hidroksiapatit dari tulang ikan. Keunggulan pembuatan
HAp dari tulang ikan yaitu dapat langsung disintesis tanpa memerlukan
penambahan unsur P. Serbuk HAp didapat melalui proses sintering dengan suhu
900°C selama 5 jam dan dilakukan formulasi lapisan tahan api. HAp memiliki
rendemen 51,11 ± 0,08%, rata-rata ukuran partikel 5,675 μm, kristalinitas 62,45%
dengan struktur senyawa heksagonal dan rasio Ca/P 2,21. Hasil analisis TGA-DSC
dan FTIR menunjukkan bahwa hidroksiapatit berhasil disintesis dari tulang ikan
tuna. Pengujian ketahanan api dilakukan pada kayu jabon merah yang dilapisi HAp
dan epoksi dengan perbandingan 0:0, 0:1, 1:1, 2:1 dan 3:1 yang dibakar selama 10
detik pada suhu 300°C. Lapisan HAp:epoksi dengan perbandingan 3:1 memberikan
hasil terbaik dalam memadamkan api dan memiliki zona pirolisis terendah. Hydroxyapatite (HAp) is an inorganic compound composed of phosphorus which has ability to increase fire resistance properties. This compound is obtained from the synthesis of fish bones in by-product of tuna fish processing. This study aims to create and determine the characteristics of fire resistance coating based on hydroxyapatite from fish bones. The advantage of making HAp from fish bones is that can be synthesized directly without addition of phosphorus. HAp powder was obtained through sintering process at 900 °C for 5 hours and a flame retardant layer was formulated. The yield obtained 51,11 ± 0,08%, an average particle size of 5,675 μm, a percentage of crystallinity 62,45% with a hexagonal structure, Ca/P ratio of 2,21. Results of TGA-DSC and FTIR analysis showed that HAp was successfully synthesized from tuna fish bones. The fire resistance test was carried out on jabon merah wood coated with HAp and epoxy in a ratio of 0:0, 0:1, 1:1, 2:1 and 3:1 which was burned for 10 seconds at 300 °C. The HAp:epoxy layer with a ratio of 3:1 gave the best results in fire extinguish and produced the lowest pyrolysis zone. |
