以甲基丙烯酸丁酯(BMA)和苯乙烯(St)为单体,二乙烯苯(DVB)为交联剂,偶氮二异丁腈(AIBN)为引发剂,聚乙烯醇(PVA)为分散剂,水为分散介质,运用悬浮聚合法制备了自溶胀型高吸油树脂.通过正交试验考察了单体配比、交联剂用量、引发剂用量和分散剂用量对树脂吸油性能的影响.结果表明:当m(BMA):m(St)=5:5、交联剂用量、引发剂用量和分散剂用量分别为单体总质量0.5%、2%和2%时,吸油树脂吸油倍率达到14.12 g?g?1,吸附动力学研究发现此时吸油速率最大;通过热重表征和重复吸油试验,合成的高吸油树脂能够重复吸油多次,第五次的吸油倍率能够达到第一次的93%.

The highly oil absorptive resin was prepared by suspension polymerization of using butyl methacrylate (BMA) and styrene (St) as the monomer, divinylbenzene (DVB) as the crosslinking agent, azodiisobutyronitrile (AIBN) as the initiator, polyvinyl alcohol (PVA) as the dispersing agent and water as the dispersed phase in this paper. Effects of mass ratio of monomers, crosslinking agent dosage and initiator dosage on resin properties were investigated by the orthogonal test. The results show that the oil absorption capacity of the synthesized resin is as high as 14.12 g?g?1 when the mass ratio between BMA and St is 5:5, the mass fraction of the crosslinking agent, initiator and dispersant are 0.5%, 2% and 2% of the total monomer, respectively. Meanwhile, through the adsorption kinetics study, it was found that the above resin has the maximum oil absorption rate. In addition, the TG and reusability of oil absorption experiments show that the resin can be used repeatedly many times, the oil absorption amount of the fifth reused times can reach 93%oil absorption amount of the first time.
