The invention discloses a method for preparing a foam material reinforced silica aerogel composite material and relates to silica aerogel. The method comprises the following steps of: preparing silica plural gel and aging the silica plural gel, modifying and drying. Through test, porosity is 80 t o 95 percent, density is 0.15 to 0.5g / cm<3>, the Brunauer-Emmett-Teller (BET) specific surface area is 600 to 1,100m<2> / g, and a water contact angle is 130 to 160 degrees; the foam material reinforced silica aerogel composite material is super hydrophobic; aerogel pore size distribution is relativelycentralized and the pore size of the aerogel is 2 to 50nm; and coefficient of heat conductivity is 0.01 to 0.035 W / (m.K), compression strength is 0.3 to 2Mpa (2 percent deformation), and elastic modulus is 1 to 5 Mpa. Meanwhile, the foam material reinforced silica aerogel composite material has good heat insulation performance, and adsorption performance, environment-friendliness and the other excellent performance. The method is simple, is short in a cycle, low in cost, and high in safety, and contributes to large-scale production; and by the method, excellent performance of the aerogel can be kept and the mechanical property of aerogel can be improved.
