摘要:
为提高硅橡胶泡沫（SRF）的阻燃性能和耐火性能，采用室温脱氢法制备以纳米NiO为阻燃剂的SRF材料，通过极限氧指数（LOI）、UL-94试验、锥形量热仪（CONE）和烟密度测试以及热重分析，并使用Coats-Redfern方法计算12种机理函数下SRF的热解活化能，研究纳米NiO对SRF体系阻燃抑烟性能和热稳定性的影响。研究结果表明：添加纳米NiO后，SRF的垂直燃烧等级均达到V-0级，添加20%纳米NiO时SRF的LOI为28.4%；对比原样，热释放速率峰值（PHRR）和生烟速率峰值（PSPR）分别降低了34.56%和72.22%，最大烟密度（MSD）和烟密度等级（SDR）分别下降了58.40%和52.20%，拉伸强度、断裂伸长率以及抗压强度分别增加了40%、65.93%和125.60%；20%的纳米NiO显著提升了SRF复合材料的活化能。研究结果可为SRF材料阻燃抑烟性能的研究提供借鉴。
Abstract:
In order to improve the flame retardancy and fire resistance of silicone rubber foam (SRF),the SRF material with NiO nanoparticles as flame retardant was prepared by the room temperature dehydrogenation method.Through the ultimate oxygen index (LOI),UL-94 test,cone calorimetry (CONE) and smoke density tests and thermogravimetric analysis,the Coats-Redfern method was used to calculate the pyrolysis activation energy of SRF under 12 mechanism functions,and the influence of NiO nanoparticles on the flame retardancy and smoke suppression performance and thermal stability of SRF system was studied.The results show that all the vertical combustion grades of SRF reach V-0 level after the addition of NiO nanoparticles,and the LOI of SRF is 28.4% when 20% NiO nanoparticles are added.Compared with the original sample,the peak heat release rate (PHRR) and peak smoke generation rate (PSPR) decrease by 34.56% and 72.22%,respectively,the maximum smoke density (MSD) and smoke density rating (SDR) decrease by 58.40% and 52.20%,respectively,and the tensile strength,elongation at break and compressive strength increase by 40%,65.93% and 125.60%,respectively.20% of NiO nanoparticles significantly improve the activation energy of SRF composites.The research results can provide reference for the study on the flame retardancy and smoke suppression performance of SRF materials.
