摘　　要：聚丙烯(PP)珠粒发泡材料具有优异的耐热、隔音、抗冲击以及耐化学腐蚀等性能,近年来被广泛应用在包装、建筑、汽车等行业。PP在其熔点温度附近的熔体强度会急剧下降,低熔体强度导致其难以得到好的泡孔结构,所以PP珠粒发泡的技术难度大,目前只有少数国家掌握了PP珠粒发泡的技术,因此PP珠粒发泡的研究受到了国内外的广泛关注。文中从制备工艺、发泡装备、性能改进、表征方法等方面综述了近年来国内外PP珠粒发泡的研究动态,并对该领域今后的研究方向进行了展望。Polypropylene（ PP） bead foam material has excellent properties such as heat resistance,sound insulation,impact resistance,chemical corrosion,etc. which has been widely used in packaging,construction,automotive and other industries in recent years. Due to the low melt strength of PP,it was very difficult to realize PP bead foaming with well forming properties,and this research attracts extensive attentions. At present,only a few countries have mastered PP bead foaming technology. This paper reviewed the recent research of the preparation,equipment,performance improvements and characterization for PP bead foam in detail. The research orientation of the field in the future was also suggested.
