Abstract

PURPOSE:To prevent the formation of rust after removing rust by emulsifying an aqueous soln. contg. hydrochloric acid as a principal component and a chlorohydrocarbon, adding specified amounts of the polyethylene oxide adduct of N- alkyltrimethylenediamine, colloidal silica powder and N-methyl-2-pyrrolidone to the emulsion, and causing gelation. CONSTITUTION:An aqueous soln. contg. hydrochloric acid as a principal component or further contg. one or >=2 kinds among phosphoric acid, nitric acid and sulfuric acid is mixed with a chlorohydrocarbon such as methylene chloride or trichloroethylene, and the mixture is emulsified. To the emulsion are added 0.5- 3% polyethylene oxide adduct of N-alkyltrimethylenediamine, 10-30% colloidal silica powder and 3-10% N-methyl-2-pyrrolidone, and gelation is caused.
