| 摘要 | Flame-retardant nano-coatings have been prepared by adding nano-concentrates with nanometer layer double hydroxides (nano-LDHs) and nanometer titanium dioxide (nano-TiO2) to ammonium polyphosphate-pentaerythritol-melamine (APP-PER-MEL) coating. The dispersion and stability principle of nanoparticles is analyzed by using transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). The effect of nano-LDHs and nano-TiO2 on the improvement in fire-resistant and anti-ageing properties of the APP-PER-MEL coating is investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD), Differential thermal analysis (DTA), Thermogravimetry (TG) and fire protection test. The DTA and TG data show that the thermal decomposition of nano-LDHs at 310-430 degrees C is helpful to the char formation of the APP-PER-MEL system at 300-440 degrees C. The XRD and SEM data show that the thermal decomposition of nano-LDHs leads to the formation of an intercalated nanostructure of the char and mixed metal oxides (Al2O3 and MgAl2O4). The intercalated nanostructure can improve the anti-oxidation property of the char structure.
Accelerated ageing badly affects the chemical action and interaction of ammonium polyphosphate, pentaerythritol and melamine in traditional APP-PER-MEL coating, whereas the flame retardants in the nano-coating still have a very good interaction even after 500 h accelerated ageing. Nano-TiO2 can greatly improve anti-ageing properties of flame-retardant coating by its excellent ultraviolet-blocking power, and nanoscale interpenetrating network formed by uniformly dispersed nanoparticles can enhance the resistance of the coating to moisture in natural weathering.
