聚苯乙烯发泡材料广泛应用于保温、缓冲包装、餐饮包装等多个领域,聚苯乙烯树脂本身具有的特点,如难于环境降解性、较低的耐温性、冲击性能差、加工过程易产生有毒有害气体等,影响了聚苯乙烯泡沫材料的加工回收方式,决定了其的应用温度范围。开发更高耐温等级、更优冲击性能的聚合物发泡材料一直得到学术界和工业界的关注。相对于聚苯乙烯,聚丙烯(PP)具有明显的力学性能优势和耐温优势,以及一 Polystyrene foam materials are widely used in many fields such as heat preservation, buffer packaging and catering packaging. Polystyrene resin has its own characteristics, such as difficult to environmental degradation, low temperature resistance, poor impact performance, easy processing Produce toxic and harmful gases, affecting the processing of polystyrene foam recycling methods, determines the application of its temperature range. Development of higher temperature grades, better impact properties of polymer foam material has been the academic and industrial concerns. Compared with polystyrene, polypropylene (PP) has obvious advantages of mechanical properties and temperature resistance, as well as a
