| titleOfInvention | A kind of phosphate-free water treatment agent and the preparation method and application thereof |
| abstract | The invention discloses the applications in processing cycle water of preparation method and the phosphate-free water treatment agent of a kind of phosphate-free water treatment agent, phosphate-free water treatment agent.The phosphate-free water treatment agent is obtained by dimethyl diallyl ammonium chloride, unsaturated carboxylic acid and acrylic ester polymerization and the limiting viscosity of the phosphate-free water treatment agent is 0.05 0.16dL/g, the unsaturated carboxylic acid is selected from acrylic acid, maleic acid, methacrylic acid or methylene-succinic acid, and the acrylate is selected from methyl acrylate, ethyl acrylate or hydroxypropyl acrylate.The method for preparing the phosphate-free water treatment agent includes：At 50 95 DEG C, monomer, initiator and molecular weight regulator are mixed in a manner of dropwise addition, the reaction was continued 1 4h, the monomer are dimethyl diallyl ammonium chloride, unsaturated carboxylic acid and acrylate at 75 95 DEG C after being added dropwise to complete.The phosphate-free water treatment agent of the present invention has preferable scale inhibitor effect, while having preferable flocculating effect to the suspended matter in recirculated water. |
