发泡聚丙烯作为聚烯烃泡沫塑料的一种,凭借其耐化学腐蚀、机械性能良好、耐热及易降解回收等优点,近年来越来越多地应用于包装、汽车制造、保温材料等领域。然而,常规聚丙烯发泡性较差,直接对其进行发泡处理不易得到泡沫塑料产品,针对这一缺点国内外进行了诸多研究。综述了近年来在热学性能、力学性能及缓冲性能方面对聚丙烯进行改性、提升其发泡性能的研究以及发泡聚丙烯产品在生产生活当中的应用。
Foamed polypropylene,as a part of polyolefin plastic foam,has many advantages such as corrosion resistant,excellent mechanical properties,heat resistance,easy degradation recovery and so on.In recent years,more and more polypropylene products are applied to packing,vehicle production,thermal insulation and so many other areas.However,conventional polypropylene has poor formability,it's hard to get plastic foam product from general polypropylene by method of foaming process.There are a sea of studies aim at this disadvantage by the researches of polypropylene modification at home and abroad.The modification advance of thermal properties,mechanical properties and cushioning properties,and the application of polypropylene products in daily life recent years were described.
