【摘要】：以聚丙烯为基材,固体石蜡为稀释剂,聚乙烯蜡为增容剂,取代芳基酰胺类化合物为成核剂,通过热致相分离法,制备了聚丙烯膜材料。探讨了制膜条件对聚丙烯膜材料相分离过程和结构的影响。结果表明,相分离温度随着制膜条件中各组分质量分数的增大,呈现先增后减的变化趋势,改变成膜条件可以很好地控制膜的结构。当聚乙烯蜡质量分数为5%、成核剂为2%、固体石蜡为33%、聚丙烯为35%时,聚丙烯膜材料的综合性质良好。
[Abstract]:Polypropylene membrane materials were prepared by thermal phase separation with polypropylene as substrate solid paraffin as diluent polyethylene wax as compatibilizer and substituted aryl amides as nucleating agent. The effect of membrane preparation conditions on the phase separation process and structure of polypropylene membrane materials was discussed. The results show that the phase separation temperature increases first and then decreases with the increase of the mass fraction of each component in the film preparation condition. The structure of the film can be well controlled by changing the film forming condition. When the mass fraction of polyethylene wax is 5, nucleating agent is 2, solid paraffin wax is 33 and polypropylene is 35, the comprehensive properties of polypropylene membrane are good.
