Tensile Properties and Morphology of Recycled Latex Glove Filled Epoxidized Natural Rubber (ENR50) Compounds

摘要

The effects on the properties of recycled latex glove (RL-G) filled Epoxidized Natural Rubber (ENR 50) were studied. Both compounds were prepared by two roll mill at five different compositions of RL-G (5, 15, 25, 35 and 50 phr). The size range of RL-G particles i.e., S_1 (300μm-700μm) and S_2 (3cm-5cm) were used. The properties such as tensile properties (tensile strength, elongation at break, and stress at 100% elongation) and morphology studies were determined. The results indicated that the both size, S_1 and S_2 of recycled latex glove filled ENR 50 blends exhibited an increased in tensile strength and elongation at break for increasing weight ratio of RL-G. Scanning electron microscopy (SEM) of the fracture surfaces shows that the fine size, S_1 RL-G/ENR50 exhibited high surface roughness and matrix tearing lines than the coarse size, S_2 thus improving the compatibility of RL-G/ENR50 compounds. The results overall indicated that the fine size, S_1 of RL-G filled ENR50 contributed to the better properties such as tensile strength and surface morphology compared to the coarse size, S_2 mainly at 15 phr of RL-G content.
