一种NaOL-AA-SAS三元共聚物表面活性剂及其制备方法和应用
摘要：
本发明提供了一种NaOL‑AA‑SAS三元共聚物表面活性剂及其制备方法和应用。该NaOL‑AA‑SAS三元共聚物表面活性剂由摩尔比为1:(1～4):(1～2)的单体油酸钠、单体丙烯酸和单体甲基丙烯磺酸钠在引发剂过硫酸铵的作用下通过聚合反应生成。本发明制备的NaOL‑AA‑SAS三元共聚物表面活性剂与市售低分子脱墨剂相比，其分子量更大，对油墨的分散、捕集及乳化能力更强，可单独使用或与低分子表面活性剂复配后作为脱墨剂进行废纸脱墨，再生出的纸张白度高，残余油墨量少，特别适用于废旧杂志纸的浮选脱墨，具有良好的应用前景。
摘要（英）：

The invention provides a NaOL-AA-SAS terpolymer surfactant and a preparation method and application thereof. Under the function of an ammonium persulfate initator, the NaOL-AA-SAS terpolymer surfactant is generated through the polymerization reaction by monomer sodium oleate, monomer crylic acid and monomer sodium methallyl sulfonate of which the molar ratio is 1:(1-4):(1-2). Compared with a market low-molecular deinking agent, the prepared NaOL-AA-SAS terpolymer surfactant has larger molecular weight, and stronger dispersing, trapping and emulsifying ability to the ink. The NaOL-AA-SAS terpolymer surfactant can be used alone or used as the deinking agent for waste-paper deinking after compounded with the low-molecular surfactant, the regenerated paper has high whiteness, and the amount of the residue ink is small. The NaOL-AA-SAS terpolymer surfactant is suitable for the floatation deinking of the waste magazine paper, and has good application prospect.
