摘要/Abstract

摘要： 采用Fe²⁺-H₂O₂-二氧化硫脲(TD)氧化还原体系引发甲基丙烯酸缩水甘油酯(GMA)与桉树漂白木浆接枝共聚,并通过交联制得吸油功能材料——GMA接枝纤维。研究了各因素对接枝纤维接枝率及吸油率的影响。红外图谱证明GMA已成功接枝到纤维素上。结果表明:当反应温度 55 ℃,单体浓度 0.14 mol/L,H₂O₂质量浓度 0.20 g/L,TD质量浓度 1.00 g/L,交联剂邻苯二甲酸二烯丙酯树脂(DAP)用量 5.0 %,反应液比控制在50∶1(mL∶g),接枝纤维对0^#柴油的吸油率可达 17.6 g/g;在很大范围,接枝纤维吸油率随着接枝率的提高而增加;接触角和环氧基含量随着纤维接枝率的提高而增大。纤维表面极性是影响其吸油率的主要因素。

Abstract: Cellulose-g-glycidyl methacrylate (GMA) was obtained from graft copolymerization of bleached eucalyptus pulp with GMA induced by Fe²⁺-H₂O₂-thioureadioxide (TD) redox system via the crosslinking reaction. Influences of each factor on grafting percentage and oil adsorption rate of the cellulose-g-GMA were investigated as well. The FT-IR spectra of cellulose-g-GMA indicated that GMA monomer had been successfully grafted onto the cellulose backbone. The results showed that the oil adsorption rate of cellulose-g-GMA toward 0^# diesel can achieve 17.6 g/g when reaction temperature was 55℃, monomer dosage was 0.14 mol/L, H₂O₂ dosage was 0.20 g/L, TD dosage was 1.00 g/L, DAP dosage was 5.0 %, liquor ratio was 50∶1(mL∶g) respectively. Generally the oil adsorption rate increased with the increasing grafting percentage, and the contact angle, as well as the epoxy group content of cellulose-g-GMA were augmented with the increasing of grafting percentage. The fiber surface polarity of cellulose-g-GMA is the main factor which influences the oil adsorption rate.
