The invention discloses a method for preparing a gradient aluminum-silicate electronic packaging material through a laser cladding melt-spinning material. The method is characterized in that a cast aluminum-silicate alloy is taken as a substrate, the aluminum-silicate alloy melt-spinning material processed through a rapid setting method is taken as a cladding material, a laser is utilized for conducting laser cladding, so that aluminum-silicate alloy melt-spinning material with different mass percentages is accumulated layer by layer on the surface of the substrate, and accordingly the aluminum-silicate electronic packaging material with the constituent elements are distributed in gradient is obtained. The aluminum-silicate gradient material is prepared through laser cladding and by utilizing the aluminum-silicate alloy melt-spinning material, the preparation method has the advantages that the gradient layer formation speed is high, the preparation time is short, and the gradient layerthickness is easy to control, the automation degree is high, and the preparation method is easily applied to large-scale industrial production.
