In the prior art, Wang Guangjiang et al. have studied the synthesis process of itaconic acid (IA)-acrylic acid (AA) binary copolymer aqueous solution and the effect on CaCO 3 The scale inhibition effect (Industrial Water Treatment, 2000,20(4): 25-26), the experimental results show that the IA-AA copolymer has a good effect on CaCO 3 The anti-scaling effect is good, and the adaptable temperature range is wide, and the significant anti-scaling effect can be obtained when the amount of the copolymer is small, but the price of acrylic acid is expensive in the experiment, which increases the production cost of the copolymer
Wu Yunjuan and others disclosed the synthesis of itaconic acid-sodium propylene sulfonate copolymer (Industrial Water Treatment, 2007, 27(11): 26-27), which has a certain scale inhibition rate and corrosion inhibition performance, but the ideal effect still exists certain gap

The invention relates to a preparation method of a copolymer water treatment agent, which is obtained by copolymerizing monomer itaconic acid and sodium methacryl sulfonate, and the mass ratio of itaconic acid and sodium methacryl sulfonate is 4.5:1 ~5.5:1, the present invention uses itaconic acid and sodium methacrylate as monomers, uses ammonium persulfate as an initiator, and isopropanol as a chain transfer agent to effectively promote the polymerization of the two monomers, so that the polymerization reaction The conversion rate is high, and the obtained polymer has good scale inhibition performance and iron oxide dispersion performance.
Description
A kind of preparation method of copolymer water treatment agent technical field The invention belongs to water treatment technical field, be specifically related to a kind of preparation method of copolymer water treatment agent. Background technique [0002] At present, in the field of water treatment, the scaling phenomenon of the water system is generally alleviated by adding a scale inhibitor. Commonly used antiscalants Mainly divided into inorganic salts, organic phosphine compounds, natural polymers and synthetic polymers. Inorganic salts and organic Phosphine compounds have been rarely used because they are easy to promote the reproduction of bacteria and algae in the system and make the water eutrophic. natural polymer Although it is cheap and easy to obtain, the scale inhibition effect is poor and the impurity content is high. As a result, a low-phosphorus and environmentally friendly synthetic polymer scale inhibitor was obtained. It has received extensiv...
