The invention provides a double-layer composite ventilation grille structure and a preparation method thereof.The double-layer composite ventilation grille structure comprises an inner-layer composite overall grille structure and an outer-layer composite overall grille structure, the inner-layer composite overall grille structure comprises an inner-layer frame and a plurality of inner-layer single-V-shaped strips, and the outer-layer composite overall grille structure comprises an outer-layer frame and a plurality of outer-layer single-V-shaped strips; the outer-layer composite material integral grating structure comprises an outer-layer frame and a plurality of outer-layer single V-shaped strips; the inner-layer frame and the outer-layer frame are square frames with the same size; the two ends of each inner-layer single V-shaped strip are connected with the inner-layer frame into a whole, and the connecting positions are V-shaped sealing faces. The two ends of each outer-layer single V-shaped strip are connected with the outer-layer frame into a whole, the connecting positions are V-shaped sealing faces, and the outer sides of the two outer-layer V-shaped strips are connected with the outer-layer frame into a whole. And the inner-layer frame is fixedly connected with the outer-layer frame. The process is simplified, the production efficiency is improved, and the surface quality and the manufacturing precision of the ventilation grille are improved.
