纳米填料在不饱和聚酯(UP)包覆层改性中的应用前景

The Applied Prospects of Nano-filler in the Modification of Unsaturated Polyester Inhibitor

不饱和聚酯(U P)作为固体推进剂包覆层存在固化物脆性大、低温延伸率低、阻燃耐烧蚀性差的缺点,为了克服这些缺点,文献中提出了一些用纳米填料改性U P包覆层的方法,文章索集了用纳米填料改性U P韧性和阻燃性的最新进展和应用前景,附参考文献21篇。

Unsaturated polyester （UP） as a solid propellant inhibitor has deficiencies of great fragility of solidification, low cofficient of elongation at low temperature, poor flame retardancy and resistant ablation . In order to overcome the deficiencies, some methods of modifying UP inhibitor by nano-filler are presented in references. In this paper, the current situation, recent progress and applied prospects in the toughness and flame retardancy of modifying UP inhibitor by nano-filler are summarized and reviewed with 21 references.
