          摘要:

          使用溶劑熱法將HKUST-1〔Cu3(BTC)2, BTC為1,3,5-苯三甲酸〕負載到聚磷酸銨(APP)的表面制得HKUST-1@APP,然后將不同量的HKUST-1@APP與環氧樹脂(EP)混合后固化制備HKUST-1@APP / EP阻燃復合材料。通過水平垂直燃燒測定儀、氧指數測定儀、電子拉力機等對EP復合材料進行了阻燃和力學性能分析。結果表明,當HKUST-1@APP的添加量為總體系的5%時,復合材料EAC-5的極限氧指數為27.5 %,垂直燃燒測試(UL-94)通過V-1級。添加HKUST-1@APP后,樣品殘炭的AD/AG(拉曼光譜中無定形碳的碳原子與晶體碳中SP2雜化的碳原子振動分別形成的D峰與G峰的峰面積比)降低到0.043,而添加總質量5%APP的EA-5的AD/AG為0.3161,說明HKUST-1@APP還可以改善環氧樹脂燃燒過程中產生的炭層,使炭層更連續、石墨化程度更高。

          Abstract:

          The HKUST-1@APP was prepared by loading HKUST-1〔Cu3(BTC)2, BTC means trimesic acid〕on the surface of ammonium polyphosphate (APP) via solvothermal method. The flame-retardant composites (HKUST-1@APP/EP) were prepared by mixing different amounts of HKUST-1@APP with epoxy resin (EP). The flame retardant and mechanical properties of EP composites were investigated by horizontal and vertical combustion tester,, oxygen index tester, electronic tensile machine, et al. The results showed that while adding 5% of HKUST-1@APP, the limiting oxygen index of EAC-5 was 27.5%, and the vertical combustion test (UL-94) passed the V-1 level. The AD/AG(the peak area ratio of D and G peaks formed by the vibration of carbon atoms in amorphous carbon and SP2 hybrid carbon atoms in graphite carbon in Raman spectrum)of the residual char was reduced to 0.043 compared to 0.3161 of EA-5 which was added 5% APP. It indicated that HKUST-1@APP could improve the char layer produced during combustion and make the char layer more continuous and graphitized.
