Neutral-color low-reflection LOW-E coated glass and preparation method thereof

The invention relates to neutral-color low-reflection LOW-E coated glass and a preparation method thereof.The coated glass comprises a glass substrate, an antireflection film layer, two or three composite film layers and a top protection layer, the antireflection film layer, the two or three composite film layers and the top protection layer are sequentially arranged on the surface of one side of the glass substrate in a plated mode from inside to outside, and each composite film layer comprises a dielectric layer, a seed layer, a functional layer and a barrier layer which are sequentially arranged; the antireflection film layer is adjacent to the dielectric layer of the composite film layer adjacent to the antireflection film layer, the barrier layer of the composite film layer adjacent to the antireflection film layer is adjacent to the dielectric layer of the composite film layer adjacent to the antireflection film layer, the top protection layer is adjacent to the barrier layer of the composite film layer
