| 總結: | Recycled polystyrene (RPS)/rubber seed kernel powder (RSKP) composites at O, l,
3, 5, and 10 wt% of RSKP were prepared in an internal mixer at 180°C with 60 rpm
of rotor speed for 8 minutes. Processing torque, tensile strength, elongation at break,
Young's modulus and impact strength decreased with higher RSKP loadings, but
water absorption increased. In comparison to virgin polystyrene (VPS)/RSKP,
RPS/RSKP composites had lower processing torque, tensile strength, elongation at
break, impact strength and water absorption. Maleic anhydride (MAH) incorporation
into RPSIRSKP composites showed higher tensile strength, elongation at break,
Young's modulus and impact strength as compared to RPSIRSKP composites. The
presence of MAH increased the impact strength at l, 3, and 5 wt% of RSKP
loadings. Modifying of RSKP filler with natural rubber latex improved tensile
strength, elongation at break and impact strength for RPS/RSKP composites.
