| description |
The utilization of waste rubber from recycled natural latex gloves (rNL-G) by means of
compounding together with synthetic rubber: acrylonitrile butadiene rubber (NBR)
could represents a new product with an acceptable properties. Results in first series
which NBR/ rNL-G compounds particularly fine size up to 20 phr loading of rNL-G,
showed overall improvement in cure characteristic, tensile, physical and thermal
properties compared to coarser size and other rNL-G loading. Meanwhile, in second
series, the incorporation of sawdust short fiber (SD) as natural filler at different loading
was studied with optimum rNL-G loading filled NBR from the first series. Results
indicated that, the addition of SD loading at 5 phr increased the adhesion between NBR
matrix, which led to improve the cure characteristics such as lower cure time and
increase the stiffness and rigidity such as modulus and hardness. At third series, the
addition of 6 phr of trans-polyoctylene rubber (TOR) as a compatibilizer has increased
the crosslinking density and enhanced the incorporation of NBR/ rNL-G compounds,
therefore improving the compatibility of NBR/ rNL-G compounds. Most of cure
characteristics, tensile, physical and thermal properties of compatibilised NBR/ rNL-G
compounds, particularly 6 phr TOR showed better overall properties than
uncompatibilised NBR/ rNL-G compounds. The combination of all material referring
from optimum loading of 1st series at 20 phr rNL-G/ fine size, 2nd series at 5 phr SD and
3rd series at 6 phr TOR. The NBR/ rNL-G /SD/TOR compound exhibited the most
improvement properties particularly the thermal stability, tensile and physical
properties. The tensile fracture surface of all series were supported by scanning electron
microscopy (SEM) observation proved the behavior of optimum strength of each
compound respectively. |
