The invention relates to an auxiliary agent for treating papermaking sludge and a preparation method thereof. The preparation method of the auxiliary agent for treating papermaking sludge of the present invention comprises: combining a comonomer, an initiator, an emulsifier and a solvent Mixing, free radical polymerization or redox polymerization to obtain the auxiliary agent; the comonomer is composed of the following raw materials in weight percentage: 20-40% branched aromatic monomers containing unsaturated groups A, 0-20% anionic monomer B, 20-50% unsaturated monomer C and 30-60% cationic monomer D, wherein the sum of the weight percentages of A, B, C and D is 100% . The auxiliary agent for treating papermaking sludge of the present invention has the advantages of ensuring that the mechanical properties of the paper are not reduced, and saving energy and reducing emissions. |
