摘要 摘要:本文研究了纳米复合材料交联制备交联羧甲基纤维素的方法。使用二氧化硅纳米复合材料二氧化硅-丙烯酸羟丙酯(SiO2-HPA)和羧甲基纤维素钠为原料,在碱性条件下二氧化硅纳米复合材料可与羧甲基纤维素钠未取代羟基发生交联,最终制备得到交联羧甲基纤维素,且制备的交联羧甲基纤维素钠具有透光度高、粘度高,抗盐性好等特点,具有极大的工业应用价值。 This article shows a method of Preparation of cross-linked Carboxymethyl cellulose with Nano material. Under the alkaline environment , silica-nano material could cross the unsubstituted hydroxyl on carboxymethyl cellulose then form the cross-linked CMC, which owns a high light transmittance, viscosity and salt resistance, so has great industrial application value
