| 中文摘要: |
| 在本研究中以DOPO衍生物和异氰酸酯聚合形成的阻燃聚氨酯作为壳层，全氟己酮作为芯层制备全氟己酮微胶囊，再与三聚氰胺-甲醛树脂复合得到全氟己酮微胶囊灭火模块。制得的全氟己酮微胶囊灭火模块在60oC烘箱放置36小时的保留率为96.7%，表明其具有优异的储存稳定性。将全氟己酮微胶囊灭火模块和市场上购买的小型气溶胶灭火装置通过小尺寸电缆沟道的灭火试验进行灭火效果对比可以发现，全氟己酮微胶囊灭火模块能在8min内灭掉火源，且灭火过程中不产生大量烟气，对元器件没有任何损伤。全氟己酮微胶囊灭火模块在电力行业、储能行业主流的灭火装置市场中具有广阔的应用前景。 |
| 英文摘要: |
| In this study, a flame-retardant polyurethane formed by the polymerization of DOPO derivatives and isocyanate was used as the shell layer, and perfluorohexanone (PFH) was used as the core layer to prepare PFH microcapsules, which were then compounded with water-soluble melamine-formaldehyde resin to obtain the PFH microcapsule fire-extinguishing module. The retention rate of the prepared PFH microcapsule fire extinguishing module placed in an oven at 60 °C for 36 h was 96.7%, indicating that it has excellent storage stability. Through a fire-extinguishing test conducted in a small-sized cable trench, a comparison was made between the PFH microcapsule fire-extinguishing module and a small aerosol fire-extinguishing device purchased on the market, revealing that the PFH microcapsule fire-extinguishing module can effectively extinguish the fire within 8 min, while generating minimal smoke during the process. The PFH microcapsule fire-extinguishing module boasts several advantages, le fire-extinguishing module will enable it to have broad application prospects in the mainstream fire-extinguishing device markets in the power industry and energy storage industry. |
