摘　　要：高密度聚乙烯(HDPE)是性能优异的通用合成树脂,在工农业生产中有着广泛的应用,在渔业上主要是用作深水抗风浪网箱框架材料。但由于HDPE作为网箱框架材料在户外使用时存在着严重的老化现象,一旦其出现严重的老化不仅严重影响到网箱的使用寿命,甚至由于HDPE框架的老化产生断裂会造成巨大的经济损失。本文归纳并阐述了HDPE的老化机理,阐述了用无机纳米粒子改性HDPE进而提高其耐老化性能,重点归纳了几种用于改性HDPE的无机纳米粒子及其特性,阐明了这几种无机纳米粒子改性HDPE耐老化的机理和优势,总结了国内外无机纳米粒子表面处理方法及纳米改性HDPE耐老化性能的最新研究进展及发展趋势。High density polyethylene （HDPE） is a kind of excellent general synthetic resins, which is widely used in industry, agriculture, national defense, construction and household goods. It is also widely applied in fisheries, primarily as cage framework. However, HDPE faces a serious problem of aging when used outdoors, which limits its further application in fisheries. This paper described the aging mechanism of HDPE, elaborated on the use of HDPE modified by inorganic nanoparticles to improve the aging resistance performance, summarized several kinds of inorganic nanoparticles for modified HDPE, and clarified the advantages of using inorganic nanoparticles to enhance the aging resistance of HDPE and the advantages of anti-aging modification of HDPE with these inorganic nanoparticles. In addition, progress of the surface modification of inorganic nanoparticles and anti-aging modification of HDPE with nanotechnology were concluded.
