The invention discloses oxidation-resisting corrosion-resisting aluminum profile rare earth silane treating fluid. The oxidation-resisting corrosion-resisting aluminum profile rare earth silane treating fluid is made from raw materials including, by weight, 120 parts to 130 parts of CeCl37H2O, 180 parts to 190 parts of H2O2, 1.6 parts to 1.8 parts of tetrabutyl titanate, 2.2 parts to 2.3 parts of chitosan, 0.5 part to 0.6 part of acetylacetone, 0.4 part to 0.5 part of H2SO4, a proper amount of deionized water, 1 part to 1.2 parts of tetraethoxysilane, 5 parts to 5.2 parts of methyl triethoxysilane, 50 parts to 53 parts of ethyl alcohol, 10 parts to 11 parts of ammonium hydroxide, 15 parts to 15.6 parts of fluorine-silicon-contained ylate emulsion and 2 parts to 2.5 parts of nanometer zirconium dioxide. According to the fluid, micropores and cracks on the surface of a film formed by the treating fluid are obviously reduced, the compactness is high, and a certain hydrophobic property is achieved; through using of the tetrabutyl titanate, the chitosan, the acetylacetone and the H2SO4, the crosslink level of the passivation film can be strengthened, forming of surface gathering objects can be restrained, and corrosion resistance and oxidation resistance of the passivation film can be strengthened.
