| 摘 要： | 以硫酸铝和尿素为原料,山梨醇为模板剂,利用均相沉淀法在高压釜中反应合成了NH4Al（OH）3.24（CO3）0.38.H2O（AACHH）阻然晶须,研究了CO2相对浓度对合成产物及形貌的影响.XRD、FT-IR、PM和TG/DTA分析结果表明：在通入10 min的CO2的条件下可以制备出形状完好的AACHH晶须,晶须长径比为10~20,晶须释放阻燃气体为NH3、CO2和H2O,完全分解其失重量为57.9%.

| Abstract: | Using aluminum sulfate and urea as raw materials,sorbitol as template,AACHH retardant whiskers were prepared by homogeneous precipitation method in the autoclave.The research focused on the effect of the relative concentration of CO2 on the products and their morphologies.The whiskers were analyzed by XRD,FI-IR,PM and TG/DTA.The results showed that: AACHH retardant whiskers with perfect morphology could be prepared under the condition the gas flushed with CO2 for 10 minutes.The length-diameter ratios of the... |
