摘要/Abstract

摘要：

为改善聚合物材料的火灾安全性,利用二硫化钼(MoS₂)的独特性能,结合纳米复合、催化成炭等设计思路,采用共沉淀法制备CeMnO_x-MoS₂和CeFeO_x-MoS₂双金属氧化物-MoS₂纳米杂化物,并将其分别应用到2种典型聚合物(聚氨酯和环氧树脂)中。结果表明:2种杂化物均匀分散在聚合物基体中,可有效延缓聚合物材料的热降解速率、提高残炭率,复合材料燃烧时释放的可燃性气体以及CO等毒性气体和烟密度明显降低,火灾安全性能明显提高。

Abstract:

In order to improve fire safety of polymer materials, considering unique properties of molybdenum disulfide (MoS₂), and based on nanocomposite and catalytic carbonization technology, CeMnO_x-MoS₂ and CeFeO_x-MoS₂ nanohybrids were synthesized by co-precipitation method and then incorporated into two typical polymer matrices (Thermoplastic polyurethane and Epoxy resin). The results indicate that the two kinds of nanohybrids are uniformly distributed in polymer matrix, which effectively delays thermal degradation of polymer materials and increases char residues at high temperature. Moreover, the addition of nanohybrids leads to the decreases of flammable gas, CO and smoke density during combustion of polymer composites, indicating significant improvement of fire safety performance.

Key words: molybdenum disulfide (MoS₂), hybrids, dispersibility, polymer material, fire safety
