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.
