以硝酸镁、硝酸铝和尿素为原料,并加入十二烷基磺酸钠制备了疏水性镁铝氧化物。以丙烯酸丁酯(BA)、甲基丙烯酸丁酯(BMA)和苯乙烯(St)为单体,聚乙烯醇(PVA)为分散剂,乙酸乙酯为致孔剂,过氧化苯甲酰(BPO)为引发剂,N,N′-亚甲基双丙烯酰胺(MBA)为交联剂,加入一定量疏水性镁铝氧化物,合成镁铝双金属氧化物复合丙烯酸酯系吸油树脂,并对该复合树脂的吸油性能进行了性能测试。结果表明,复合树脂对四氯化碳、三氯甲烷和甲苯的最高吸附倍率分别为42.89、36.29、26.85g/g。对复合树脂吸附四氯化碳的动力学模型拟合结果表明,复合树脂吸油符合准一级动力学模型。复合树脂的热重分析结果表明,复合树脂比原树脂的热稳定性有一定提高。
With magnesium nitrate, aluminum nitrate and urea as raw materials, sodium dodecyl sulfate was added to prepare a hydrophobic magnesium aluminum oxide. A kind of poly (vinyl alcohol) (PVA) as dispersant, ethyl acetate as porogen, benzoyl peroxide (BMA) and styrene BPO) as initiator and MBA as crosslinking agent, a certain amount of hydrophobic magnesium aluminum oxide was added to synthesize Mg-Al bimetallic oxide composite acrylate-based resin and The performance of the composite resin oil absorption performance test. The results showed that the highest adsorption capacity of composite resin for carbon tetrachloride, chloroform and toluene were 42.89,36.29,26.85g / g respectively. The fitting results of the kinetic model for the adsorption of carbon tetrachloride on the composite resin show that the composite resin absorbs oil in accordance with the quasi-first-order kinetic model. Thermogravimetric analysis of the composite resin shows that the thermal stability of the composite resin is higher than that of the original resin.
