摘要
以棉短绒为基材,丙烯酸长链酯为单体,双丙烯酸二元醇酯为交联剂,采用悬浮接枝共聚法合成了高吸油性材料,考察了棉纤维与单体的投料比、交联剂种类与用量、引发剂用量、聚合反应温度与时间等因素对该材料吸油性能的影响,得到了不同丙烯酸长链酯与棉纤维接枝聚合制备吸油材料的最佳工艺条件。当以丙烯酸辛酯为单体,对棉纤维和单体总重量的比为60％,以1,4-二丙烯酸丁二醇酯为交联剂,其用量为0.6％时,制得吸油材料的最高吸油倍率为16.0g／g。
High oil absorption resins of higher n-alkyl acrylates modified cotton linter were synthesizedby supension graft copolymerization. The effects of the ratio of n-alkyl acrylates to linter, the kinds and amounts of crosslinker, the amounts of initiator, as well as reaction temperature and time on oil absorbency were investigated. The optimum reaction conditions were obtained, as to the example of n-octyl acrylate graft copolymer, the weight ratio of monomer to total raw materials is 60 % , the amount of crosslinker 1,4-butane-diol diacrylate is 0. 6%, the oil absorbency of this resin is 16. 0 g/g.
