    • A method for the preparation of a silica aerogel monolith in the atmosphere pressure is provided to prevent surface cracking frequently generated due to drying and contraction in ambient pressure drying by controlling the molar ratio of an organic precursor and methyl alcohol, thereby imparting flexibility to a wet gel of an intermediate step, and reduce the preparation cost by simplifying the preparation process. In a preparation method of a silica aerogel, a method for the preparation of a silica aerogel monolith comprises: a gelling process(S1) of diluting an organic precursor into methanol, adding oxalic acid as an acidic catalyst into the diluted solution in a concentration of 0.01 to 0.1M to hydrolyze the mixed solution for 24 hours, and adding a basic catalyst into the hydrolyzed material to gel the material at a temperature of 25 to 30 deg.C; and a drying process(S2) of drying the hydrophobic gel at a temperature of 50 to 300 deg.C in the atmosphere pressure. The organic precursor is one or more selected from the group consisting of methyltrimethoxysilane, trimethylchlorosilane, hexamethyldisilazane, trimethylethoxysilane, ethyltriethoxysilane, and phenyltriethoxysilane. The basic catalyst is one selected from the group consisting of ammonia water(NH4OH), potassium hydroxide(KOH), and sodium hydroxide(NaOH), and the basic catalyst is added after adding the acidic catalyst. Further, a mole rate(MeOH/MTMS) of the methyltrimethoxysilane and methanol is 30 to 40.
