摘　　要：为探究喷火油料凝胶形成的基本机制,基于精制直馏油分、二异辛酸铝及二甲酚的复配体系,测试了不同凝油剂配比条件下油料凝胶的表观粘度特性,通过原子力显微镜(AFM)对喷火油料凝胶的微观形貌进行表征,利用傅里叶变换红外光谱(FTIR)研究了油料凝胶的分子作用机制。研究结果表明:二异辛酸铅含量越高,凝胶的表观粘度也越高,较初始表观粘度的下降值减小;二异辛酸铝分子在非极性溶剂体系中通过氢键形成致密的网状结构,使得非极性溶剂分子的运动被限制,进而形成油料凝胶。To explore the fundamental mechanism of flamethrower oil gel formation,based on the compound system of refined straight run oil,aluminum 2-ethylhexanoate and xylenol,the apparent viscosity of oil gel with different gelling factor proportions was investigated.AFM was applied to characterize the microscopic morphology of the flamethrower oil gels,FTIR was used to study the interaction mechanism at molecular level.The results show that the higher content of aluminum 2-ethylhexanoate,the higher apparent viscosity of gel,and the lower reduced value compared to the initial apparent viscosity;Aluminum 2-ethylhexanoate can form a dense network in nonpolar solvent by hydrogen bonds,which restrict the movement of solvent molecules to form gel.
