摘要: 采用微波辐射法制备了聚甲基丙烯酸甲酯-甲基丙烯酸丁脂(PMMA-BMA)吸油烟树脂,并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,探讨了单体配比、引发剂用量、分散剂用量、交联剂用量、微波功率对树脂吸附油烟性能的影响.结果表明:当MMA/BMA质量比为0.8:1,引发剂、分散剂和交联剂的用量分别为0.4%,0.3%和0.35%时,所合成的树脂有较高的吸油烟率,60℃时吸油烟率达0.191;在此工艺条件下,与常规的水浴加热合成方法相比,微波辐射合成树脂不仅可将反应时间由6h缩短至2h,而且其吸油烟率也高于常规法树脂、普通活性炭和商品化G-1651型高吸油树脂.

Abstract:

Polymethylmethacrylate-butylmethacrylate (PMMA-BMA) resin was prepared by means of microwave irradiation. The morphologies and textural properties of the product were then characterized using SEM. Moreover, the effects of monomer proportion, the initiator dosage, the dispersant dosage, the cross-linking agent dosage and the microwave power on the oil fume-adsorbing capacity of the resin were investigated. The results show that the adsorption ratio is up to 0. 191 at 60℃ when the mass ratio of MMA to BMA is 0.8:1 and when the dosages of the initiator, the dispersant and the cross-linking agent are respectively 0. 4%, 0. 3% and 0.35%. As compared with the traditional water-bath heating, microwave irradiation shortens the reaction time from 6 h to 2 h and results in a greater adsorption capacity even than those of the activated carbon and the commercial high-capacity G-1651 resin.
