The invention discloses an outdoor acrylic light diffusion plate, which is prepared from the following components in parts by weight: 60 to 80 parts of polymethyl methacrylate, 10 to 15 parts of amorphous transparent fluororesin, 3 to 8 parts of light diffusion agent, 2 to 8 parts of aliphatic dihydric alcohol, 1 to 5 parts of photoinitiator and 0.1 to 1 part of cross-linking agent. The outdoor acrylic light diffusion plate is prepared by adopting an ultraviolet light irradiation crosslinking method. The advantages of various materials are utilized, organic combination is carried out, then an ultraviolet light irradiation method is utilized, under the action of the photoinitiator and the cross-linking agent, rapid compounding is carried out to generate a three-dimensional net-shaped cross-linking structure, in the cross-linking process, the light diffusion agent can be well dispersed in the cross-linking structure, and the phenomenon that a traditional light diffusant is prone to falling off on the surface of
