【摘要】 选取不同发泡体系(低能耗发泡体系和纯W331发泡体系),制备发泡聚丙烯珠粒及发泡聚丙烯(EPP)成型制品(重卡卧铺)。同时对EPP发泡制品成型性能、力学性能、热学性能、承重性能、装配情况等进行系统研究。通过EPP成型制品的工艺参数、合格率，判定低能耗发泡体系优势，实现降低生产成本及节能减排的目的。更多还原

【Abstract】 We choose different foaming systems(low energy consumption and W331) to prepare foamed polypropylene beads(EPP) and sleeper for heavy-duty truck; At the same time, comparison of technological parameters, mechanical properties, thermodynamic properties, displacement change value, field assembly were systematically studied. Through comparison of technological parameters and the qualification rate of EPP molded products, the advantages of low energy consumption foaming system are determined to achieve the purpose of reducing production cost, energy conservation and emission reduction.更多还原
