Abstract
Penelitian ini dilakukan untuk membuat resin epoksi tahan api dengan kombinasi penambahan serat tanaman pisang. Material tahan api dibuat dengan mensintesis kitosan dan ammonium polifosfat (CS-APP). Serat tanaman pisang dilakukan treatment NaOH untuk menghilangkan pengotor dan meningkatkan kekuatan serat. CS-APP berhasil disintesis dan dilakukan uji FTIR. Resin Epoksi (EP)+CS-APP di modifikasi dengan penambahan serat tanaman pisang variasi berat 5%, 10%, 15%, dan 20%. EP/CS-APP+Serat dikarakterisasi dengan FTIR, DSC, dan uji pembakaran Horizontal Burning Test UL-94 ASTM D 635. Hasilnya pada CS-APP menunjukkan terjadi reaksi antara kitosan dengan ammonium polifosfat sehingga terbentuk material tahan api. Hasil TGA dan DSC menunjukkan bahwa sampel yang kehilangan massa terkecil ada pada sampel EP/CS-APP dengan variasi 20% serat tanaman pisang sebesar 39,676 % pada Tmax 749,39 °C. Uji Pembakaran menghasilkan nilai kecepatan bakar rata rata atau Rate of Burning (ROB) terendah untuk EP/CS-APP+20% serat sebesar 0,141 mm/s dan tertinggai pada EP/CS-APP tanpa penambahan serat sebesar 0,184 mm/s. Uji FTIR hasil Pembakaran menunjukkan terbentuknya ikatan P-O-C untuk memberikan satabilitas termal pada resin akibat terbentuknya residu karbon. *********************************************************** This research was conducted to make a flame retardant epoxy resin with a combination of the addition of banana plant fibers. The refractory material is made by synthesizing chitosan and ammonium polyphosphate (CS-APP). Banana plant fibers were treated with NaOH to remove impurities and increase fiber strength. CS-APP was successfully synthesized and FTIR test was performed. Epoxy resin (EP)+CS-APP was modified with the addition of banana plant fiber with a weight variation of 5%, 10%, 15%, and 20%. EP/CS-APP+Fibers were characterized by FTIR, DSC, and Horizontal Burning Test UL-94 ASTM D 635. The results on CS-APP showed the reaction between chitosan and ammonium polyphosphate to form a refractory material. The results of TGA and DSC showed that the sample with the smallest mass loss was in the EP/CS-APP sample with a variation of 20% banana plant fiber of 39.676% at Tmax 749.39 °C. The Burning Test resulted in the lowest average burn value or Rate of Burning (ROB) for EP/CS-APP+20% fiber of 0.141 mm/s and the highest on EP/CS-APP without the addition of fiber speed of 0.184 mm/s. Burning FTIR test showed the formation of P-O-C to provide thermal stability to the resin due to the formation of residue.
