摘要
聚丙烯是一种开发应用非常广泛的通用塑料,但受紫外线、氧气和热的作用易发生老化致使性能下降,限制了其应用范围和发展前景。针对这一问题,综述了聚丙烯改性的方法,同时也介绍了聚丙烯老化机制和国内外抗老化聚丙烯的研究现状,并指出研究改性抗老化聚丙烯材料将具有深远的理论意义和实际应用价值。
Polypropylene is a general-purpose plastic with a very wide range of development and application.Howerer,it is prone to aging due to the effects of ultraviolet rays,oxygen and heat,resulting in performance degradation which limites its application scope and development prospects.In view of this problem,the modification methods of polypropylene are summarized,the aging mechanism of polypropylene and the research status at home and abroad are also introduced,and it is pointed out that the research of modification of aging resistant polypropylene material will have far-reaching theoretical significance and practical application value.
