摘要

聚苯乙烯泡沫塑料是高度使用的包装材料之一,因为它的重量轻,隔振性能。聚苯乙烯泡沫塑料的使用量每年都在上升,但由于经济可行性差,回收设施很少接受回收后消费的聚苯乙烯泡沫塑料。本研究的目的是探讨回收后消费泡沫聚苯乙烯作为原料生产可持续复合材料的潜在价值。因此,本研究将增加聚苯乙烯回收的可行性和兴趣,并间接延长聚苯乙烯废物的生命周期。本研究以再生聚苯乙烯(rPS)、椰子壳(CS)和马来化聚苯乙烯(MAPS)为原料,采用内混炼机进行复合。研究了各组分对复合材料的转矩、流变、弯曲和形态性能的影响。结果表明,CS含量较高的rPS/CS复合材料由于粘度的增加而具有更高的加工扭矩。然而,MAPS的加入降低了复合材料的粘度。抗弯性能表明,当CS含量为30%时,未添加MAPS的rPS/CS复合材料的抗弯强度和模量分别达到33.5 MPa和3.1 GPa。然后,添加MAPS分别平均提高29%的抗弯强度和14%的抗弯模量。扫描电镜结果表明,MAPS的加入改善了rPS基体与CS颗粒之间的界面粘附,从而改善了材料的弯曲性能。rPS/CS复合材料的弯曲性能与文献中发现的木塑复合材料(WPC)相当,这表明其在类似WPC的应用中具有潜力。

Effect of Coupling Agent on Properties of Composites Made from Styrofoam Waste and Coconut Shell
Styrofoam is amongst one of the highly used packaging materials due to its lightweight and vibration isolate properties. The usage of styrofoam rises yearly, but it is seldom received by the recycling facilities to recycle the post-consumed styrofoam due to the poor economic viability. The objective of this research is to investigate the potential value of recycling post-consumed styrofoam as feedstock in producing sustainable composite materials. Therefore, this study would increase the feasibility and interest in recycling of styrofoam and indirectly continue the life cycle of styrofoam waste. In this study, the composites with varying compositions were of recycled polystyrene (rPS), coconut shell (CS) and maleated polystyrene (MAPS) compounded using an internal mixer. The effects of compositions on torque rheological, flexural and morphological properties of the composites were investigated. The findings showed that rPS/CS composites filled with more CS content possesses higher processing torque due to increase in viscosity. However, addition of MAPS lowered the viscosity of composites. The flexural properties revealed that the rPS/CS composites without MAPS exhibited the highest flexural strength and modulus of 33.5 MPa and 3.1 GPa, respectively, when the CS content was measured at 30 wt%. Then, the addition of MAPS improved on average 29% of flexural strength and 14% of flexural modulus, individually. The results from scanning electron microscopy showed that the addition of MAPS had improved the interfacial adhesion between rPS matrix and CS particles, which resulted in an improvement on flexural properties. The flexural properties of rPS/CS composites are comparable to wood plastic composites (WPC) as found in literature, which demonstrates its potential to be used in applications similar to WPC.
