摘要
以棉浆粕(纤维素)为基材、甲基丙烯酸烷基酯为接枝单体、双丙烯酸二元醇酯为交联剂,采用悬浮接枝聚合法合成了纤维素基吸油材料。用FTIR和SEM手段对产物的结构进行了表征,考察了引发剂的种类及用量、接枝单体种类及用量、交联剂种类及用量、反应温度和反应时间等因素对吸油材料吸油率的影响。纤维素基吸油材料的最佳合成条件:m(棉浆粕)∶m(K2S2O8引发剂)∶m(甲基丙烯酸丁酯接枝单体)∶m(双丙烯酸二元醇酯(B)交联剂)=1∶0.025∶1.5∶0.005,75℃下恒温反应6h;在此条件下合成的纤维素基吸油材料对大豆油、二甲苯和柴油的吸油率达到最大值,分别为16.2,14.3,13.7g/g。
The cellulose-based oil absorption materials were synthesized from alkyl methacrylate and cotton pulp(cellulose)by suspension graft copolymerization with glycol diacrylate as crosslinker. The structure of the synthesized graft copolymers were characterized by means of FTIR and SEM. Effects of type and dosage of initiators, type and dosage of grafting monomers, type and dosage of crosslinkers, reaction temperature, and reaction time on oil adsorptions of the products were investigated. Under the optimal conditions of m ( cotton pulp) : m ( K2S208 initiator) : m ( butyl methacrylate grafting monomer) : m(glycol diacrylate(B) crosslinker) 1 : 0. 025 : 1.5 : 0. 005, 75 ℃ and 6 h, oil absorptions of the synthesized material to soy bean oil, xylene and diesel oil could reach 16.2, 14.3 and 13.7 g/g, respectively.
