| titleOfInvention | Itaconic acid aspartic acid SSS copolymerization research of non-phosphorus scale inhibitor and preparation method thereof |
| abstract | The invention discloses itaconic acid aspartic acid SSS copolymerization research of non-phosphorus scale inhibitor, belong to reverse osmosis membrane technical field of water treatment chemical, it is that monomer copolymerization is synthesized by itaconic acid, aspartic acid and SSS, and Polymer Formulation is as follows： In formula (I), m, n, a, b is 1~10 integer.The invention also discloses its preparation method.The present invention is by the way that the functional groups such as carboxyl, amide group and sulfonic acid group are introduced into molecule so that the polymer all has excellent scale inhibition and dispersion performance to calcium carbonate, calcium sulfate and calcium phosphate；The preparation method of the itaconic acid aspartic acid SSS copolymer of the present invention, the raw material of synthetic copolymer is easy to get, and reaction condition is gentle, and copolymerization product is biodegradable, it is without phosphorus, on environment without influence, synthesis cost and post processing expense are low. |
