The invention discloses energy-saving self-luminous laminate flooring and a preparation method thereof. The flooring comprises a lower base material layer, a middle base material layer, a printing layer and an ultraviolet curing wear-resistant coating which are arranged from bottom to top sequentially and manufactured integrally, wherein the middle base material layer and the lower base material layer are made of a hollow glass bead doped and modified resin material, and the ultraviolet curing wear-resistant coating is made of an ultraviolet curing coating doped and modified with hollow glassbeads and long afterglow powder. The preparation method comprises the following steps: firstly, the hollow glass beads and the long afterglow powder are subjected to surface modification and then fully mixed with the resin material, an auxiliary and the like, and the finished laminate flooring is prepared by hot pressing, printing, film evaporation, tempering, curing, punching and the like. The laminate flooring has the advantages of being long in afterglow time, high in brightness, good in stability, good in heat preservation performance, environmentally friendly, non-toxic, pollution-free, radioactivity-free, energy-saving, consumption-reducing, attractive, practical and wide in application prospect.
