[0012] Example
[0013] The production method of the "water-in-water" emulsion papermaking retention aid of the present invention is as follows: acrylamide monomer and deionized water are formulated into an aqueous solution, which is generally prepared at a weight concentration of 20%, and ion exchange is carried out with an ion exchange column. Until the conductivity is less than 10us / cm, measure its concentration, and calculate the amount of acrylamide required for 1 ton of mixed monomer aqueous solution based on the concentration, and pump it into an adjustable temperature and sealable stainless steel batching kettle with a stirring device. Measure the molar ratio of acrylamide dimethylamino ethyl chlorobenzyl salt, polyamine, and ammonium sulfate according to the reaction requirements. Add these chemicals to the acrylamide solution. Use deionized water to adjust the mixed monomers in the batching kettle. The concentration is 35%.
