摘要： 在研究ADP结块原因和防结块措施的基础上，以硬脂酸（SA）为防潮剂，以水和水/无水乙醇混合溶液分别作为防潮剂溶剂，采用溶剂蒸发法对ADP进行防潮改性以达到降低其吸湿性和防结块的目的。研究了溶剂蒸发温度、搅拌速度、防潮剂含量、溶剂种类、溶剂加入体积等工艺条件对ADP复合材料粒度大小的影响，制备了不同工艺条件下的ADP复合材料，并对其粒度和吸湿性进行了测试。结果表明，当SA质量分数为3%，以15 mL水和15 mL无水乙醇混合溶液为溶剂，在90 ℃的蒸发温度下，搅拌速度为400 r/min，对ADP复合材料的防潮效果最佳，其粒度为50 μm，吸湿率由2.79%降为0.92%，并进行了理论分析。

Abstract: Based on the study of the caking reason and anti-caking measures of ADP, stearic acid (SA) was used as moisture-proof agent, water and water / anhydrous ethanol mixed solution were used as moisture-proof agent solvent respectively, and solvent evaporation method was used to modify ADP to reduce its hygroscopicity and achieve the purpose of anti-caking. The influence of process conditions such as solvent evaporation temperature, stirring speed, moisture-proofing agent content, solvent type, and solvent addition volume on the particle size of ADP composites was studied. ADP composites under different process conditions were prepared, and their particle size and moisture absorption were tested. The results show that when the SA content is 3%, the mixed solution of 15 mL water and 15 mL absolute ethanol is used as the solvent, the evaporation temperature is 90 ℃, and the stirring speed is 400 r/min, the moisture-proof effect of the ADP composite is the best: the particle size is 50 μm, the moisture absorption rate is reduced from 2.79% to 0.92%, and then the theoretical analysis is carried out.
