บทคัดย่อ (EN): Expanded polystyrene (EPS) is a major class of thermoplastics. The recycling of EPS involves much technological challenges stemming mainly from its very low bulk density (15-50 kb/m3). Its light weight, while being a valuable attribute, makes the material transportation cost high and limits recycling to nearby localities. In this study, this waste material has been utilized for blending with silica-reinforced natural rubber (NR). Partial replacement of NR by small percentage of NR even by a small percentage of a waste material can have considerable impact on the economic viability of NP processing. The NR/EPS blends were prepared by melt mixing in a Brabender Plasticorder at 140°C for 8 min. Since NR and EPS are incompatible and immiscible a method has been devised to improve compatibility. For this, EPS and NR were initially grafted with maleic anhydride (MA) using the initiator dicumyl peroxide (DCP) to give a graft copolymer. Various graft copolymers were prepared by changing the NR/EPS ratios as 35/5, 30/10, 25/15 and 20/20. For all copolymers, MA and DCP concentrations were maintained at 1phr and 0.15 phr respectively. Grafting was confirmed by Fourier Transform infrared spectroscopy (FTIR). The grafted blend was subsequently blended with more of NR during mill compounding giving blend compositions with ratios of 95/5, 90/10, 85/15 and 80/20 between NR and EPS. A sulphur curing system was employed for the compounds. Silica reinforced NR compounds were also prepared employing the same NR/EPS blends. Morphological studies using scanning electron microscopy (SEM) showed better dispersion of EPS in the compatibilized blend. By this technique, the tensile strength, elongation at break, modulus and tear strength of most compositions were found to be either at par with or better than that of virgin silica filled NR compound. It is also noted that the thermal properties of the blends are equivalent to that of virgin NR. The study establishes the potential of this method for replacing of NR by waste EPS to some extent. While this addresses to some extent the environmental problems arising from waste EPS this technique has the potential to make NR processing more economical.
