中文摘要:
      以甲基丙烯酸丁酯(BMA)、甲基丙烯酸异辛酯(2-EHM)和苯乙烯(St)为原料,以过氧化二苯甲酰(BPO)为引发剂,聚乙烯醇(PVA)为分散剂,二乙烯基苯(DVB)为交联剂,改性凹凸棒(OATP)为无机添加物,在微波辐射下合成了P(BMA/2-EHM/St)复合凹凸棒高吸油树脂。探讨了苯乙烯、引发剂和凹凸棒质量分数以及反应温度等主要因素对树脂吸油倍率的影响,并用响应面法对合成工艺进行了优化,采用IR、TGA、SEM等对产物进行了结构表征和热性能及表面形貌的分析。实验结果表明:当w(St)=52.54%、m(2-EHM) : m(BMA)=1:1.5、w(BPO)=1.95%、w(DVB)=0.60%、w(PVA)=3.00%、w(OATP)=2.00%,聚合温度82℃、反应时间70min、微波功率为700W时,所制得的高吸油树脂吸油倍率最大,对四氯化碳、二氯甲烷、甲苯和二甲苯的吸油倍率分别达到37.24g/g、30.50g/g、19.64g/g、16.81g/g,添加OATP后树脂的热分解温度提高了32℃。
英文摘要:
      Using Butyl methacrylate(BMA), 2-ethylhexyl methacrylate(2-EHM) and styrene(St) as raw material, polyvinyl alcohol(PVA) as dispersant agent, benzoyl peroxide(BPO) as initiator, divinylbenzene(DVB) as crosslinking agent, modified attapulgite as inorganic additive to prepare high oil-absorption resin with microwave irradiation. The major influences, including mass fraction of initiator,styrene, OATP and reaction temperature were studied. Meanwhile, the structure, thermal performance and surface topography of oil-absorption resins were analyzed by FTIR, TGA and SEM, respectively. The result shows: when w(St)=52.54%、m(2-EHM) : m(BMA)=1:1.5、w(BPO)=1.95%、w(DVB)=0.6%、w(PVA)=3%、w(OATP)=2.0%,at 82℃,reaction time is 70min, microwave power is 700W, it has the maximum oil absorbency to carbon tetrachloride, dichloromethane, toluene and xylene. That is 37.24, 30.50, 16.94 and 16.81g/g, respectively, the thermal decomposition temperature of the resin was improved 32℃ after adding OATP into the resin.
