Abstract

The invention discloses a circulated cooling water compounded scale inhibitor and a preparation method of the circulated cooling water compounded scale inhibitor. The circulated cooling water compounded scale inhibitor is prepared by weighing polyaspartic acid, 1-hydroxy ethylidene-1,1-diphosphonic acid, polyepoxysuccinic acid, amino trimethylene phosphonic acid, deionized water, sodium hexametaphosphate, a dispersing agent, polyhydric alcohol phosphate ester, organic polybasic phosphonic acid, acrylic acid-acrylic acid phosphonic hydroxypropyl acrylate and organic solvent according to a ratio in parts by weight. According to the circulated cooling water compounded scale inhibitor and the preparation method, disclosed by the invention, the content of phosphor in a water treatment agent is reduced, the generation rate of calcium phosphate scales is reduced, and the corrosion inhibition speed ranges from 0.001mm/a to 0.01mm/a; the scale inhibition rate is up to 98 to 100 percent; the expiration date is long, the circulated cooling water compounded scale inhibitor can be stored for one month under 60 to 70 DEG C, and the scale inhibition effect is up to 99 to 100 percent.

Description

Technical field [0001] This application is the field of test agent process, especially involving an environmentally friendly and well -corrosion -resistant recycling dirt and preparation methods.
