【摘要】：以木棉纖維為基材、甲基丙烯酸甲酯為接枝劑,通過接枝反應(yīng)制備了木棉基復(fù)合材料�？疾炝私又┓磻�(yīng)濃度、反應(yīng)溫度和反應(yīng)時間等因素對復(fù)合材料吸油性能的影響,實驗結(jié)果表明,影響吸油量的主要因素是接枝劑濃度,其次是反應(yīng)溫度;木棉纖維的最佳接枝工藝為:接枝劑濃度2 mol/L,溫度95℃,時間60 min。采用掃描電鏡、紅外光譜對所制備木棉基復(fù)合材料的表面形貌及結(jié)構(gòu)進行了表征,結(jié)果表明,接枝后的木棉纖維表面變得較為粗糙,接枝上了一定量的甲基丙烯酸甲酯,并且對柴油的吸附性能得到了很大提高。
[Abstract]:The wood fiber is used as the base material, and the methyl methacrylate is the grafting agent, and the wood-cotton-based composite material is prepared by the grafting reaction. The effects of the reaction concentration of grafting agent, reaction temperature and reaction time on the oil absorption property of the composite were investigated. The experimental results show that the main factors that affect the oil absorption are the concentration of the grafting agent, followed by the reaction temperature. The optimum grafting process of the wood fiber is as follows: the concentration of the grafting agent is 2 mol/ L, The temperature is 95 鈩，
