摘要： 采用改性粉煤灰制备内墙调湿性涂料是对固废粉煤灰在功能涂料中应用的新尝试。 通过测试不同颜料体积浓度的粉煤灰内墙涂料的吸放湿性能，发现其在涂层中颜料体积浓度（PVC）与临界颜料体积浓度（CPVC）接近时调湿性最优，同时涂层的接触角出现了一个拐点。 粉煤灰涂料经过多次水洗后，外观变化较小，当粉煤灰涂料的 PVC≤CPVC 时，涂层（4#与 5# ）各方面性能可以达到ＧGB/T 9756—2009《合成树脂乳液内墙涂料》中的要求，可以被应用于内墙涂料中。

Abstract: A new humidity-controlling coating based on modified fly ash for interior wall is reported firstly in this paper. The moisture absorption and desorption of the interior coatings with fly ash having different pigment volume concentrations(PVC)were investigated. indicating that the coating film had excellent humidity controlling property and the smallest contact angle when the PVC reached the critical pigment volume concentration (CPVC). The interior coating film based on fly ash had a slight change in appearance after repeated washing test. Specifically, the coating film with PVC sCPVC(e.g,4# and 5#)showed good performance qualified to the requirements of GB/T 9756-2009, suitable for application in the interior wall.
