| dc.description.abstract | Made of the kompon cis-1,4 isoprene (natural rubber} SIR 20 which have been
vulcanized and enhanced by a liquid smoke from cangkang of coconut of sawit and
phenol as antioxidant. The result of mixing between natural rubber of SIR 20
with the liquid smoke and phenol can reduce the oxidation of natural rubber of
SIR 20 to the influence shear and thermal in the moment of rubber processing.
Technique of mixing of cis-1,4 isoprene (natural rubber) SIR 20 which have been
vulcanized with the liquid smoke addition is to drop liquid smoke to natural rubber
in internal mixer with the variation of liquid smoke 0, 2, 4, 6, 8 and 10 phr of
between liquid smoke and phenol. The result from the examination indicates that
the rubber enhanced and also rubber enhanced by a liquid smoke mixture by phenol
can pursue the happening of degrading oxidize to enchain the cis-1,4 isoprene. The
matter is proved with the method FT-IR. From this examination result above indicate
that process oxidizes the thermal is more effective formed relatively at addition
:S 2 phr liquid smoke. But the addition of liquid smoke or phenol with the high
concentration (above 2 phr) reduce reaction the degrades oxidation is not effective. | en_US |
