Abstract:
Vein Nano-graphite (NG) filled natural rubber composites were prepared and measured
effects on the properties of Nano-graphite filled natural rubber (NR) composites. I report
the Exfoliation method for synthesis ofNano-graphite from chemical techniques. Produced
Nano-graphite filtrated by vacuum filtration. Nano-graphite have been characterized by
various physico-chemical techniques (include X-ray diffraction and scanning electron
microscopy). Raman spectroscopy, transmission electron microscopy, atomic force
microscopy, Fourier transform infrared, have been use to examine the morphology,
determine the size and chemical structure of Nano-graphite particles.
Exfoliated Nano-graphite treated different loading level for NR. (0 phr,l phr, 2 pkr,3 phr,
4 phr, and 5 phr). After observed effects of properties, Phygico-mechanical properties
(according to ISO methods, such as Tensile strength, Modulus, Tear strength, Elongation,
Resilience), Cure characteristics (such as Minimum toque (ML), Maximum torque (MH),
Scorch time (Tsz), Cure time (Tso), Delta cure, Cure rate index (CRI), and
Chemical resistance by swelling method (% ofswelling index (SI). The maximum tensile
strength is 23 Mpa atl phr NGA{R composite. Respectively, 1.033 Mpa,2.3966 Mpa,
6.603 Mpa are best evaluation of Modulus at I00o/o, 300% and 500o/o elongation from 4
phr NGA{R composite. 77 is maxrmum resilience of NG loading NR composites shows in
4 phr NGAIR composite.2 phr NGAIR composite is exhibit (36.4 N/mm) maximum value
of tear strength. Chemical resistance tested by toluene, n-hexane, and water absorption
according to swelling method. Higher loading of NGATIR composites represent better
enhancement of chemical resistance compare with NR composite (control).
