Abstract
The invention relates to the technical field of corrosion and scale inhibitor preparation, in particular to a phosphorus-free corrosion and scale inhibitor. The phosphorus-free corrosion and scale inhibitor is prepared from, by mass, 3%-6% of zinc oxide, 15%-25% of a 48% sodium hydroxide solution, 20%-40% of a 37% sodium salt of polyepoxysuccinic acid, 20%-40% of a 30% acrylic acid-2-acrylamido-2-methylpropanesulfonic acid copolymer and 10%-25% of distilled water. According to the phosphorus-free corrosion and scale inhibitor and a preparation method thereof, the problem that zinc salt is difficult to dissolve in an alkaline corrosion and scale inhibitor is solved, and the circulating water treatment cost is greatly reduced.
