Compression rubber adalah bagian karet yang langsung berhubungan dengan pulley penggerak roda. Penelitian ini bertujuan untuk memperbaiki sifat rheologi kompon compression rubber v-belt serta kelekatan serat pada matriks karet, optimasi kompon upper rubber, dan melakukan pencetakan produk v-belt dengan formula terbaik hasil penelitian.<br /> <br /> Sifat rheologi kompon compression rubber diperbaiki dengan mengubah jenis dan jumlah akselerator, yaitu menggunakan akselerator tunggal CBS sebanyak 1,2 phr sehingga memiliki keselamatan proses yang lebih baik. Perbaikan serat dilakukan dengan menambah perlakuan kimia terhadap serat, yaitu proses hidrolisis dan modifikasi peroksida terhada serat hasil penelitian sebelumnya yang telah mengalami proses delignifikasi dan ekstraksi. Perlakuan serat ini mampu memperoleh serat berukuran mikro (sekitar 10-15 μm) dengan kadar selulosa sebesar 80%. Kompon compression rubber menggunakan gabungan karet sintetis dan karet alam CR/RSS I: 70/30 phr, bahan pengisi serat gebang 20 phr dan carbon black N330 sebanyak 40 phr, N550 sebanyak 35 phr, dan bahan aditif lainnya.<br /> <br /> Kompon upper rubber telah berhasil dioptimasi dari formula dasar penelitian sebelumnya, menggunakan gabungan karet sintetis dan karet alam CR/RSS I: 70/30 phr, carbon black N330 sebanyak 30 phr, N550 sebanyak 30 phr, dan bahan aditif lainnya, tanpa menambahkan serat gebang. Pencetakan produk v-belt telah dilakukan dengan kerjasama antara BBKKP dengan PT. Bando Indonesia. Tahapan pecetakan produk meliputi tahap komponding menggunakan mini kneader, sheeting kompon hingga mencapai ukuran ± 0,3 cm, building, curing, v-cutting, home base cutting, dan finishing. Produk v-belt hasil penelitian juga telah diuji sesuai dengan standar JASO E-107 dan hasilnya mampu memenuhi persyaratan JASO E-107 yang diujikan. Pengujian durabilitas tidak dapat dilakukan karena alat uji yang ada di PT. Bando Indonesia sedang dalam perbaikan. </div> <!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves /> <w:TrackFormatting /> <w:PunctuationKerning />
