Embodiment 1

[0030] (1) In a four-neck flask equipped with a reflux condenser, a thermometer and a dropping funnel, add 18.375 g of maleic anhydride and 40 mL of deionized water, and dissolve under magnetic stirring. Add 50 mL of 10 mol / L NaOH solution dropwise to the solution, at this time maleic anhydride is hydrolyzed to sodium maleate. During the dropwise addition, the temperature rises, and the temperature is controlled below 55°C. After the dropwise addition, the temperature was raised to 55 °C, 0.46 g of sodium molybdate catalyst was added, and then 10 mL of 30% hydrogen peroxide was slowly added dropwise as an initiator, and the dropping time was about 0.5 h. After the dropwise addition, the temperature was raised to 70°C, and the epoxidation was carried out for 0.5 h.

[0031] (2) Add IA (itaconic acid), AMPS (2-acrylamide-2-methylsulfonic acid), sodium bisulfite, ammonium ferrous sulfate, isopropanol and thioglycolic acid to the solution. The mass ratio of ESA (epoxysuccinic ac...

Embodiment 2

[0047] (1) In a four-neck flask equipped with a reflux condenser, a thermometer and a dropping funnel, add 16.34 g of maleic anhydride and 40 mL of deionized water, and dissolve under magnetic stirring. 50 mL of 10 mol / L NaOH solution was added dropwise to the solution, at this time maleic anhydride was hydrolyzed into sodium maleate. During the dropwise addition, the temperature rises, and the temperature is controlled below 55°C. After the dropwise addition, the temperature was raised to 55°C, 0.41 g of sodium molybdate catalyst was added, and then 10 mL of 30% hydrogen peroxide was slowly added dropwise as an initiator, and the dropping time was about 0.5 h. After the dropwise addition was completed, the temperature was raised to 65°C, and epoxidation was carried out for 0.5 h.

Embodiment 3

[0064] (1) In a four-necked flask equipped with a reflux condenser, a thermometer and a dropping funnel, add 19.6 g of maleic anhydride and 40 mL of deionized water, and dissolve under magnetic stirring. 50 mL of 10 mol / L NaOH solution was added dropwise to the solution, at this time maleic anhydride was hydrolyzed into sodium maleate. During the dropwise addition, the temperature rises, and the temperature is controlled below 55°C. After the dropwise addition, the temperature was raised to 55°C, 0.49 g of sodium molybdate catalyst was added, and 10 mL of 30% hydrogen peroxide was slowly added dropwise as an initiator for about 0.5 h. After the dropwise addition, the temperature was raised to 70°C, and the epoxidation was carried out for 0.5 h.

Abstract

The invention relates to an epoxysuccinic acid polymer and a preparation method thereof and a system and method for treating water by combining the epoxysuccinic acid polymer, a magnetic field and static electricity. The epoxysuccinic acid polymer is prepared by copolymerizing, by mass, 1 part of an epoxysuccinic acid monomer, 0.2-0.4 part of an itaconic acid monomer and 0.1-0.3 part of a 2-acrylamide-2-methanesulfonic acid monomer. The epoxysuccinic acid polymer takes epoxysuccinic acid as the main monomer, integrates a carboxylic acid group, a sulfonic acid group and an amide group into a whole and has the good scale inhibiting and dispersing performances, and the scale inhibiting rate can be effectively increased when the epoxysuccinic acid polymer is combined with the magnetic field and the static electricity to conduct water treatment.

Description

technical field [0001] The invention belongs to the technical field of chemical products and water treatment, and in particular relates to an epoxy succinic acid polymer, a preparation method thereof and a combined water treatment system and method with magnetic field and static electricity. Background technique [0002] There are two methods of industrial circulating cooling water treatment: chemical dosing and physical water treatment. Among industrial water treatment chemicals, scale and corrosion inhibitors are commonly used in the largest amount, which is of great significance to prevent equipment scaling, prolong equipment life, reduce energy consumption, and ensure safe operation of equipment. Most of the water treatment agents currently on the market contain phosphorus, are non-biodegradable, and are non-environmentally friendly products. There are also some environmentally friendly water treatment agents, which have the advantages of being phosphorus-free, environm...
