The invention discloses a composite SiO2 aerogel heat insulation material and a preparation method thereof, and relates to a heat insulation window and wall surface heat insulation material. The composite SiO2 aerogel heat insulation material is composed of the following raw materials in parts by weight: 80-100 parts of distilled water, 20-40 parts of water glass, 20-30 parts of a reinforcing agent, 1-2 parts of a dispersing agent, 20-40 parts of absolute ethanol, 20-40 parts of a first modification agent, 20-40 parts of a second modification agent and 10-20 parts of a catalyst. The composite SiO2 aerogel heat insulation material has the advantages of low cost and good heat insulation, other indicators are better than that of heat insulation materials in prior art. In building heat insulation aspects, the material is saved, construction is convenient, white pollution is reduced, the aerogel mechanical properties are improved, the product surface is smooth, the structure is uniform, the shrinking percentage is small, stability is good, producing process and equipment are simplified, production cost is greatly reduced, the composite SiO2 aerogel heat insulation material is environmentally-friendly and free of pollution, the reality of turning aerogel into the building heat-insulation material can be realized.
