The invention discloses an aluminum and aluminum 
alloy efficient environmentally-friendly 
polishing solution and a preparation method thereof. The 
polishing solution comprises the following componentsin parts by weight: 0 to 20 parts of 
sodium cocoyl isethionate, 0 to 15 parts of 1-phenyl-5-
tetrazole-thione, 0 to 10 parts of 3-sulfydryl-1-
sodium propanesulfonate, 0 to 3 parts of 
copper sulfate, 0.2 to 1.5 parts of 
sodium tungstate dehydrate, 0.5 to 4 parts of a 
corrosion inhibitor, 0.2 to 5 parts of a surfactant, 20 to 50 parts of 
sulfuric acid and 20 to 35 parts of deionized water, wherein the sum of dosage of the components is 100 parts. The prepared efficient environmentally-friendly 
polishing solution is mainly applied to aluminum and aluminum 
alloy chemical polishing, a preparation technology of the polishing solution is simple, polishing speed is high, and production cost is low; the polishing solution is efficient and environmentally-friendly, and 
nitric acid and 
chromium-containing substances harmful to human bodies and the environment are not utilized; the surface of a polished aluminum profile is high in brightness, good in smoothness and free of 
corrosion spots; and additives in the polishing solution cooperate with each other, functionality of the solution is effectively improved, chemical performance of the solution is stable, and the polishing solution is suitable for 
mass production.
