[0036] A method for preparing a single-sided high-gloss 6061-H22 state aluminum alloy mirror panel, comprising the following preparation process:

[0037] S1. Put the weighed raw materials into a smelting furnace for smelting, after static refining, degassing, adding a grain refiner, filtering, and then casting by a semi-continuous casting method to obtain an ingot;

[0038] S2, heat the ingot prepared in step S1 at a temperature of 550°C-570°C for 15h-18h, and perform homogenization heat treatment;

[0039] S3. Carrying out surface milling treatment to the ingot after S2 treatment, during the surface milling treatment, ensure that the surface of the ingot after milling has no convex and concave feeling, and the roughness of the ingot surface is Ra<0.85 μm;

[0040] S4. Heating the ingot after the surface milling treatment in step S3 to 450°C-510°C, keeping it warm for more than 3 hours, and using the upper winding mode on the 1+4 type hot rolling unit to perform hot rolling into
