The invention relates to a nano environment-friendly reinforced floor with weather resistance, salt mist resistance, abrasion resistance, scrubbing resistance, excellent adhesive force, impact resistance, corrosion resistance, scratching resistance and waterproof performance and a manufacturing method. The nano environment-friendly reinforced floor comprises a base layer and a bottom layer, wherein the base layer is a density board, the bottom layer is a waterproof diaphragm layer and compounded on one side of the base layer, and the other side of the base layer is provided with a nano layer. The nano environment-friendly reinforced floor has the advantages that: 1, a new field of manufacturing the reinforced floor by using a nano material is created, and the nano reinforced floor has weather resistance, salt mist resistance, abrasion resistance, scrubbing resistance, excellent adhesive force, impact resistance, corrosion resistance, scratching resistance and waterproof performance; and 2, the nano material has effects on sterilization, rot resistance, deodorization, filtration and ultraviolet radiation resistance, so the reinforced floor is environment-friendly and healthy, and radically eliminates the harm of the noxious odor of the conventional reinforced floor to the environment and people.
