摘要：
A method of preparing a fibrous panel including surface treating a mineral wool with a water repellent agent to provide a water-repellent surface treated mineral wool, admixing the water-repellent surface-treated mineral wool with water to provide a slurry, and dewatering and drying the slurry to provide a fibrous panel. A method of preparing a mineral wool having a surface treated with a water repellent agent including contacting a water repellent agent emulsion with a mineral wool and drying the mineral wool, and a method of preparing a water-repellent surface-treated fibrous panel including mineral wool having a surface pre-treated with a water repellent agent are also provided.
