| 摘 要： | 采用自由发泡工艺研究了聚乙烯低发泡成型的配方及工艺条件，讨论了偶氮二碳酰胺(AC)、乙烯／醋酸乙烯共聚物(EVA)、过氧化二乙丙苯(DCP)用量、螺杆转数对制品性能的影响。结果发现，每100份聚乙烯中AC用量3份、EVA用量为5份、DCP用量为0．02份、螺杆转速为30r／min时，制得制品泡孔结构分布均匀，机械性能较好。

| Abstract: | Formulating and processing technology of PE low foaming extrusion were studied by free foam technology. The influence of contents of AC , EVA , DCP and the screw rotate speed on produce properties was discussed. The results showed that foam aperture was well-distributed, physical properties and mechanical properties were good when the content of PE was one hundred parts, the content of AC was 3 parts, the content of EVA was 5 parts, the content of DCP was 0.02 part and the srew rotate speed was 30rpm. |
