摘　　要：由于敦煌地处甘肃,气候条件恶劣,温度变化大,所以导致敦煌壁画易脱落、干裂等。极端的降水会导致敦煌壁画盐分结晶并与石窟壁分离。为了保护敦煌壁画,减小温度变化对敦煌壁画的影响,防止因水而导致敦煌壁画发生病害等,通过文献分析法,对气凝胶的保温隔热疏水性能和气凝胶材料在涂料方面的应用进行分析和梳理。分析结果表明:气凝胶保温隔热疏水涂料具有良好的保温隔热性能以及疏水性能,可以保护敦煌壁画免受自然灾害的侵蚀,延长敦煌壁画的寿命。Because Dunhuang is located in Gansu province where the climatic condition is harsh and the temperature variation is large,so it is easy for Dunhuang murals to fall off and crack.Extreme precipitation will cause salt crystals in Dunhuang murals to separate from the cave walls.In order to protect the Dunhuang murals,reduce the impact of temperature changes on the Dunhuang murals,and prevent water from causing disease to the Dunhuang murals,through literature analysis,the thermal insulation and hydrophobic properties of aerogel and the application of aerogel materials in coatings were analyzed and sorted out.The results showed that the aerogel thermal insulation hydrophobic coatings has good thermal insulation,thermal insulation and hydrophobic properties and can protect Dunhuang murals from natural disasters and extend the life of Dunhuang murals.
