摘　　要：凹凸棒土又被称为“万用之土”,在工业生产中有广泛应用。将其与纸质文献脱酸常用的碱性介质氢氧化镁复合,产生一种新的复合物。经反复研究,确定复合物中氢氧化镁的负载量最多为25%,同时通过透射电子显微镜(TEM)确定了复合物的状态,物性分析表明凹凸棒土是良好的脱酸材料载体,并验证复合物的形成。后将这种复合脱酸材料应用于纸张脱酸,经过对比,发现其脱酸性能优越且脱酸后纸张性能明显增强。Attapulgite clay is well-known as a“universal soil”and has been widely used in industrial production.In our study,it was compounded with magnesium hydroxide-an alkaline medium commonly used for deacidification of paper-to produce a new composite material.After several trials,it was determined that the magnesium hydroxide loading in this composite was at most 25%.The dispersion of the composite was confirmed using transmission electron microscopy(TEM).Physical property analysis showed that attapulgite clay was a good carrier for the deacidification material,and verified the formation of the composite.Subsequently,this composite material was applied to paper deacidification.Through comparison,it was found that the deacidification performance of the composite was superior and that the properties of the paper were significantly enhanced after deacidification.
