The invention belongs to the technical field of PP plastic antifogging, and particularly relates to a PP plastic antifogging sheet and a preparation process thereof.The PP plastic antifogging sheet comprises an antifogging sheet body and an antifogging coating coated on the surface of the antifogging sheet body, and the extrusion formula of the antifogging sheet comprises, by weight, 0.5 part of PP-450E raw material, 0.5 part of PP-5015 recycled material, 0.5 part of polypropylene, 0.5 part of polypropylene, 0.5 part of polypropylene and 0.5 part of polypropylene. The antifogging coating formula of the antifogging coating coated on the surface of the antifogging sheet comprises the following components in parts by weight: 1.5 parts of antifogging agent, 3 parts of water and 3 parts of alcohol. The production of the PP anti-fog extrusion sheet does not need anti-fog master batches, so that the production cost is reduced; the PP-450E raw material and the PP-5015 recycled material can promote each other, so that
