Abstract
A light reflecting material, a reflecting layer and a preparation method therefor; the light reflecting material comprises glass powder particles (1), diffuse reflection particles, ultra-fine nano particles and an organic carrier; the particle size of the glass powder particles (1) is ≤5 μm, the particle size of the diffuse reflection particles is 0.1 μm to 0.2 μm, and the particle size of the ultra-fine nano particles is 0.01 μm to 0.05 μm. The glass powder particles (1), diffuse reflection particles and ultra-fine nano particles the particle sizes of which decrease progressively in sequence by one order of magnitude are used as the raw materials of the reflecting layer, without deceasing the adhesion between the reflecting layer and a substrate, the surface area within the reflecting layer that may cause reflection or refraction is increased to obtain better reflectivity.
