dc.description.abstract |
Palm oil fly ash (POFA) as solid waste produced from crude palm oil industries consist
of quite high of silica (more than 50% w/w). This study aimed to compare the properties and
morphology of thermoset natural rubber (TNR) with POFA, silica, carbon black (CB), and mixture
of POFA-CB fillers. The filler content used is 30 phr (per hundred rubbers). The process of making
the compound was conducted by using a roll mill at room temperature and a maximum roll
rotational speed of 20 rpm. Zinc oxide 5 phr, stearic acid 2 phr, mercaptodibenzothiazyldisulfide
(MBTS) 0.6 phr, and Sulfur of 3 phr were used as curative agents. Trimethylquinone (TMQ) 1 phr
was used as an antioxidant. Commercial minarex 2.5 phr was used as a plasticizer. Vulcanization
process was carried out at a temperature of 150 °C and a pressure of 50 kg/cm^ using a hot press.
Morphology was observed using a scanning electron microscope (SEM). Measurement of tensile
properties was carried out using universal testing machine (UTM) according to ASTM D412-06a
standard. The results indicated that the use of POFA as a filler could potentially produce TNR with
quite good morphology, tensile properties and water absorption properties. A mixture of POFA-CB
with a mass ratio of 50/50 (w/w) produced the thermoset with the value of 18.5 MPa of tensile
strength, 1600% of elongation at break, and 1.2 MPa of elastic modulus |
