摘　　要：利用凹凸棒土、活性炭具有特殊的纤维结构和强大的吸附性能等特性,选择其作为调湿功能填料,并以纯丙乳液为基料,配制调湿功能涂料;重点研究了调湿涂料在周期性热湿作用下的吸放湿特性。研究结果表明:添加凹凸棒土、活性炭的涂料具有调湿功效。运用凹凸棒土研制的调湿涂料在前100h调湿效果明显;而运用活性炭制备的调湿涂料则在100h之后逐渐表现出调湿特性;添加10g活性炭的调湿涂料168h吸湿率达0.81%,放湿率为0.75%。Attapulgite clay and activated carbon were selected as humidity controlling fillers for their special structures and strong adsorption properties etc, and the humidity controlling coating was prepared from the base of pure acrylic emulsion. The moisture absorption and desorption characteristics of the humidity controlling coating in the periodic heat and moisture conditions were studied in detail. The results indicated that the coatings added with attapulgite clay and activated carbon were provided with the humidity controlling efficacy. The effect of humidity controlling of the humidity controlling coatings prepared from attapulgite clay are obvious before 100 hours, while that prepared from activated carbon appear gradually afterl00 hours. The moisture absorption ratio of the humidity controlling coatings, which were added 10g activated carbon, reached 0. 81% after 168 hours, and the moisture desorption ratio was 0. 75%.
