| dc.description.abstract | The use of appropriate and effective compatibilizer can improve the morphology and properties of material Thermoplastic Vulcanizate (TPV). This study aimed to determine the effect of the ratio of Maleated Natural Rubber (MNR) and Maleated Polypropylen (MAPP) as compatibilizer and the effect of mixing time on the morphology and properties of TPV natural rubber based. TPV samples were made in a two stage process, namely the stage of making compound and TPV material manufacturing phase. Stage of compound manufacturing is done by using a roll mill at room temperature and 20 rpm of roll speed. Compound materials include natural rubber (SIR 20), filler hybrid fly ash/carbon black and additives sulfur. The second stage of the dynamic vulcanization is carried out in the internal mixer at 175ÂșC and 60 rpm of rotor speed, mixing of rubber compound, polypropylen (PP) and double compatibilizer MNR / MAPP. Ratio of rubber compound / PP made permanent 30/70, while the ratio MNR / MAPP varied 30/70, 50/50, 70/30. Time mixing in internal mixers varied 8, 12, 16 and 20 minutes. TPV samples tested include tensile properties (standard ISO 527-2 type 5A), morphology and water absorption properties. The test results showed that the ratio of compatibilizer MNR / MAPP and mixing time affects the morphology and properties of TPV. TPV tensile properties increased with increasing mixing time to reach the optimum point and will decrease the mixing time in the past when the optimum point. Best tensile properties and morphology obtained with compatibilizer ratio MNR / Mapp 70/30 and 8 minutes mixing time with a value of 3.34 MPa tensile strength; 19.75% elongation at break; elastic modulus of 50.90 MPa and water absorption 0.759%. | en_US |
