微波辐射制备甲基丙烯酸十二酯-丙烯酸-2-乙基-己酯树脂及其吸附油烟性能

Microwave Irradiation Syntheses and Properties of Polydodecylmethacrylate-2-ethyl Hexyl Acrylate Resin for the Adsorption of Oil Fume

应用微波辐射法制备聚甲基丙烯酸十二酯-丙烯酸-2-乙基-己酯吸油烟树脂,采用扫描电子显微镜对吸油烟树脂的表面形貌和孔结构进行了表征,研究了单体配比、引发剂用量、交联剂用量、合成温度对树脂吸附气相油烟性能的影响.结果表明,当甲基丙烯酸十二酯/丙烯酸-2-乙基-己酯吸配比为3∶7,引发剂、分散剂和交联剂的用量分别为1%、1.5%和0.6%,合成温度为85℃时所合成的树脂其吸油烟率达到最大,此时树脂表面形成了较多和较深的孔。与常规条件下的合成方法相比,使用微波辐射合成WRT树脂不仅可缩短一半的反应时间,而且其吸附气相油烟率也高于普通合成法得到的NR树脂。

Polydodecylmethacrylate-2-ethyl hexyl acrylate resin was synthesized by means of microwave irradiation.Morphologies and textural properties of the synthesized resins were characterized by Scanning Electron Microscopy(SEM).The adsorption of oil fume on the resins was measured.The effects of monomer ratio,initiator dose,dispersant dose,and cross-linker dose as well as synthesis reaction temperature on the synthesized resin adsorption of oil fume were investigated.Results showed that when the monomer ratio(2-e...
