[0002] Aluminum dihydrogen tripolyphosphate is an efficient and environmentally friendly anti-rust pigment and an ideal substitute for toxic pigments such as red lead and chromate. At present, aluminum dihydrogen tripolyphosphate is generally prepared by dehydration polymerization of aluminum oxide or aluminum hydroxide and phosphoric acid. The specific method is as follows: first, aluminum oxide or aluminum hydroxide is reacted with an aqueous solution of phosphoric acid in a certain molar ratio to prepare an intermediate acid aluminum phosphate; then the intermediate is calcined to obtain anhydrous aluminum dihydrogen tripolyphosphate; the anhydrous aluminum dihydrogen tripolyphosphate is hydrated, ground, and further washed, filtered, dried, and crushed to finally obtain a relatively pure aluminum dihydrogen tripolyphosphate.
