Abstract

The purpose of this study is the manufacture of natural bentonite into nano particles and is used as a filer on thermoplastic high-density polyethylene (HDPE). The method used in the manufacture of nanoparticles of bentonite are two ways; The first synthesis method using surfactant cetyl trimethyl ammonium bromide (CTAB) and the second way in ballmill for 10 hours. Characterization of the particle size analyzer (PSA), morphological analysis with scanning electron microscope (SEM) and analysis of the structure by X-ray diffraction (XRD) was performed. Nano particles with variation of composition of natural bentonite (2, 4, 6, 8, 10% w t) blends with HDPE and compatibilizer PE-g-MA on the appliance's internal mixer at a temperature of 150oC and laboplatomil rate of 60 rpm for 10 minute. Berdasarkan PSA analysis and X-ray, natural bentonite having an average size of 75 nm for synthesis with CTAB, and 97.5 nm for the ball mill. from the results of XRD analysis of minerals crystoballite (SiO2) and phase annite (Al3.448Fe3K0.99Na 0.01O12Si 2.552). In testing the mechanical properties of the resulting increase in tensile strength and breaking up the composition perpajangan 2 to 6 % and a decline in the composition of 8%. The results of SEM analysis showed that homogeneous mixing of ingredients and the bentonite particle agglomeration on the composition of 10 % wt.
