In this study, the waste nitrile gloves were reclaimed by using mechano-chemical method to form reclaimed nitrile glove (rNBRg). The significance of reclaiming waste nitrile gloves is to protect the environment. This reclaiming process is carried out at constant concentration of tetra methyl thiuram disulfide (TMTD) and different milling time. The performance of rNBRg then was evaluated by measurement of sol content and crosslink density at different milling time times. It shows that, the best milling time was at 40 minutes. Then, nitrile gloves were then reclaimed at highest milling time which is 40 minutes before underwent rubber compounding. The process of rubber compounding is proceeding by blending all additives and styrene butadiene rubber (SBR) with reclaimed nitrile gloves at different formulation and blend ratio to form SBR/rNBRg blend. This rubber blend then undergoes several characterizations such as cure characteristics, mechanical and physical properties of SBR/rNBRg blend at different SBR/rNBRg blend ratio. The cure time and scorch time are decreases as the composition of rNBRg increases. Maximum and minimum torque is increases and decreases respectively with the increasing of rNBRg loading. It is also observed that as the loading of rNBRg increases, the hardness and modulus at 100 % elongation are increases, while the tensile strength and elongation at break are decreases. |
