Characterization And Properties Of Polypropylene Recycled Acrylonitrile Butadiene Rubber Rice Husk Powder Composites

Komposit elastomer termoplastik bagi adunan polipropilena (PP)/ getah kitar semula akrilonitril butadiene (NBRr)/ serbuk sekam padi (RHP) telah dikaji. Kesemua sampel ujian disediakan dengan menggunakan pencampur dalaman Haake Rheomix Polydrive R600/ 610 pada suhu 180°C dan kelajuan rotor 50 rpm. Sa...

Sifat-sifat mekanikal dan terma bagi kesemua komposit yang dirawat telah meningkat. Rawatan Ac telah menambahkan ciri-ciri hidrofobik RHP dan meningkatkan lekatannya dengan matrik tak berpolar PP/NBRr. Peningkatan sifat-sifat seperti tensil, kestabilan terma dan penghabluran komposit yang lebih baik ditunjukkan oleh komposit yang dirawat dengan Ac berbanding pengkupelan ɤ-APS.
