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。
Using cotton pulp (cellulose) as substrate, alkyl methacrylate as grafting monomer and diacrylate glycol as crosslinking agent, cellulose-based oil-absorbing materials were synthesized by suspension graft polymerization. The structure of the product was characterized by FTIR and SEM. The effects of the type and amount of initiator, the type and amount of graft monomer, the type and amount of crosslinking agent, the reaction temperature and the reaction time on the oil absorption rate influences. The optimum synthesis conditions of cellulose-based oil-absorbing materials were: m (cotton pulp): m (K2S2O8 initiator): m (butylmethacrylate grafting monomer): m Coupling agent) = 1: 0.025: 1.5: 0.005 at 75 ℃ for 6h. The oil absorption rate of soybean oil, xylene and diesel reached the maximum at 16.2, 14.3 , 13.7 g / g.
