The invention discloses an expanding agent for wood drying treatment and a drying method of wood. The expanding agent is composed of, by weight part, 0.5 part to 1.2 parts of CaO, 0.05 part to 0.1 part of KMnO4 and 0.1 part to 0.3 part of CuSO4. According to the expanding agent, a fiber pipe hole is rapidly swelled, a cell wall and cell cavity structure is opened, and absorbed water and free water are easily drained out. Meanwhile, Ca2+, MnO4- and the like in the expanding agent can react with harmful substances such as gum and tannin, a product can be discharged out in a manner of salt and complex compounds, the phenomenon that the harmful substances are adsorbed to wood fibers and cell cavities again is avoided, and wood stability is further improved. 本发明公开了种用于木材干燥处理的扩涨剂及木材的干燥方法。扩涨剂由以下重量份数的组分组成：CaO 0.5～1.2份、KMnO0.05～0.1份、CuSO0.1～0.3份。本发明的扩涨剂，可以使纤维管孔快速溶胀，打开细胞壁和细胞腔组织，使吸附水和自由水易于排出；同时，扩涨剂中的Ca、MnO等可与树胶、单宁酸等有害物质反应并将产物以盐类、络合物的形式排出，避免上述有害物质重新吸附到木料纤维及细胞腔中，进步增加了木材的稳定性。
