发泡聚丙烯制备与应用研究进展

Preparation and Application of Expanded Polypropylene Foam

发泡材料作为一种新型材料,以高分子为基体,大量气泡存在于其内部,被看作以气体为填料的一种复合材料。发泡材料质量轻,比强度高且具备缓冲、吸声、保温等功能,在建筑、汽车、包装、航空航天和家电等领域应用广泛。聚丙烯具有优异的热学、力学和化学稳定性,是制备发泡材料所需要的聚合物基体,聚丙烯发泡材料成为继聚苯乙烯、聚乙烯发泡材料之后21世纪最具潜力的新型发泡材料。本文总结了发泡聚丙烯的制备方法,发泡形态,改性方法和应用现状,并简要展望了这类材料的发展前景,将为发泡聚丙烯材料的应用和发展提供理论基础。

Foaming material can be regarded as a gas filled polymer composite with large amounts of bubbles in a polymer matrix.The merits of low mass,high specific strength,sound-absorbing and heat-insulation make it very competitive in building,automotive industrial,packaging industry,aerospace fields and household electrical appliances.Polypropylene can be well suited to serve as a polymer matrix to prepare foaming material due to its excellent thermal,mechanical properties and chemical stability,foaming PP become the most potential composites in the 21 st century after PS and PE foaming material This paper summarized the progress of the preparation methods,cell morphology,modification methods,applications and outlooks of expanded polypropylene(EPP).This paper may provide theoretical foundation for the applications and developments of EPP.
