A kind of preparation method of modified polyacrylamide water treatment material

Abstract

The invention discloses a method for preparing a modified polyacrylamide water treatment material. Stearic acid and triethanolamine are subjected to blending reaction, obtained ester amine is mixed with a dimethyl carbonate solution of hydroxypropyl methylcellulose to perform quaternarization, obtained quaternary ammonium salt is used to treat acrylamide monomer, and polymerization is performed under the action of an initiator, so that quaternary ammonium salt grafted polyacrylamide is obtained. The method is high in finished product stability, good in water treatment effect, safety and environmental friendliness, and excellent in overall performance.

Description

technical field

[0001] The invention belongs to the field of water treatment materials, and in particular relates to a preparation method of a modified polyacrylamide water treatment material. Background technique

[0002] Due to population growth and economic development, a series of problems affecting the quality of resources caused by excessive exploitation and unreasonable development and utilization of resources have directly threatened the survival of us and future generations; sewage treatment technology has a great impact on water saving, energy saving, etc. The problem plays a very important role, but at the same time, the use of sewage treatment chemicals also has a certain impact on the environment. In the cooling water system, in various occasions where the water temperature is higher than the ambient temperature, the scaling of calcium carbonate and other inorganic salts will bring serious consequences. In recent years, in the field of water treatment, the appl...
