Additive for treating paper-making sludge and preparation method thereof

The invention relates to an additive for treating paper-making sludge and a preparation method thereof. The preparation method of the additive for treating the paper-making sludge comprises the following steps of: mixing comonomer, an initiator, an emulsifier and a solvent, and carrying out free-radical reaction or oxidation-reduction polymerization reaction to obtain the additive. The comonomer is prepared from the following raw materials in percent by weight: 20-40% of aromatic monomer A with branch chains containing no unsaturated groups, 0-20% of anionic monomer B, 20-50% of unsaturated monomer C and 30-60% of cationic monomer D, wherein the sum of the weight percentages of A, B, C and D is 100%. The additive for treating paper-making sludge has the advantages that no reduction of themechanical property of paper is ensured and the energy-saving and emission-reducing effects are achieved. 本发明涉及种用于处理造纸污泥的助剂及其制备方法，本发明的种用于处理造纸污泥的助剂的制备方法为：将共聚单体、引发剂、乳化剂和溶剂混合，进行自由基聚合反应或者氧化还原聚合反应，获得所述助剂；所述共聚单体由下述重量百分比的原料组成：20-40％
