摘要
以苯乙酮为溶剂将蒽醌溶解,用转相法对油相进行乳化,制备出O/W型蒽醌乳液,以提高乳液在蒸煮液中的分散性。通过正交实验,得出了最佳乳化条件,并将制备的蒽醌乳液在硫酸盐法制浆中进行了应用。结果表明,最佳乳化条件为:转相温度95℃、乳化时间45 min、Span-80用量0.6 g、Tween-80用量2.0 g、Tween-20用量1.0 g、去离子水用量50 mL,采用剂在油中法进行乳化。通过蒸煮对比实验,得出蒽醌乳液较晶体蒽醌蒸煮液表面张力降低了28.4%,残碱有所提高,纸张性能也有所提高。蒽醌乳液浆色浅,纸张白度、抗张指数、耐破指数和撕裂指数分别较晶体蒽醌浆提高了6.2个百分点、4.9%、3.8%和4.7%。
In order to increase the dispersion of anthraquinone in cooking liquor, the oil-in-water （O/W） emulsion of anthraquinone was prepared by dissolving the anthraquinone with hypnone at fist then emulsifying the oil phase by using phase inversion process. The emulsification conditions were optimized by using orthogonal design, and the emulsion of anthraquinone was applied in KP cooking. The result showed that the best emulsification conditions were： phase inversion temperature was 95℃ , emulsifying time was 45 minutes, the dosages of Span-80, Tween-80, Tween-20 and water were 0.6 g, 2.0 g, 1.0 g and 50 mL respectively, anthraquinone emulsification was carried out by the method of putting the agent in the oil. In the KP cooking experiment, the surface tension of cooking liquor decreased by 28.4% and residual alkali increased in some extent compared with using crystal anthraquinone for cooking. The qualities of resultant paper including brightness, tensile index, burst index and tear index increased 6.2% 4.9%, 3.8% , and 4.7% respectively.
