Abstract

The invention discloses a preparation method of a phosphorus-free environment-friendly scale inhibitor dispersant and belongs to the technical field of scale inhibitor dispersants. The present invention first utilizes wheat starch to prepare amylose, carries out copolymerization reaction with amylose, maleic anhydride and acrylic acid to obtain amylose-maleic anhydride-acrylic acid terpolymer, and terpolymer, polyaspartic acid acid, sodium lignosulfonate and other complexing agents and deionized water, and stir and mix evenly to obtain a scale inhibitor dispersant. The scale inhibitor dispersant prepared by the present invention is economical, environmentally friendly, and efficient, and can not only inhibit calcium carbonate scale, sulfuric acid scale The copolymer of calcium scale and calcium phosphate scale, and also inhibits the copolymer of zinc scale, iron scale, silicon scale and other scales. It has good scale inhibition effect, prevents the generation of scale, and can fully disperse the scale deposited in the water system. , environmentally friendly and biodegradable.

Description

technical field

[0001] The invention discloses a preparation method of a phosphorus-free environment-friendly scale inhibitor dispersant and belongs to the technical field of scale inhibitor dispersants. Background technique

[0002] Anti-scaling dispersant is a copolymer containing carboxyl, hydroxyl, sulfuric acid, phosphonic acid groups and other groups, because its straight chain and some branches contain phosphonic acid groups, so this copolymer has excellent anti-scaling performance, and It has a certain anti-corrosion effect, can inhibit the generation of scales such as calcium carbonate and calcium sulfate, and distort the crystal lattice. It also has a good dispersion effect on iron oxide and calcium phosphate. It can be used in combination with polyphosphate, organic phosphonic acid and other corrosion inhibitors. It is generally used in open circulating cooling water systems with low concentration multiples and harsh operating conditions.
