The invention discloses a nano additive modified high strength wall self heat preservation brick and a preparation method thereof. The method comprises the following steps: according to mass portion, 1 to 20 portions of bonding agent, 0.1 to 5 portions of admixture and 0.5 to 5 portions of nano additive are evenly mixed and added with admixtures, the weight of which is 0.001 to 0.1 times against the weight of the mixture, and evenly mixed again; and the mixture obtained is added with water and shaped. For the wall self heat preservation brick prepared by the method of the invention, the pressive strength is between 5 and 14MPa, the coefficient of thermal conductivity is between 0.1 and 0.2w/m.k, so that the brick is a highly efficient energy saving building material with superior performance.
