摘　　要：以马来酸酐、壬基酚聚氧乙烯醚(TX-10)、亚硫酸钠为原料,制备出马来酸酐磺酸盐类阴离子表面活性剂,并与非离子表面活性剂AEO-9、AEO-3复配得到中性脱墨剂。通过红外光谱、抄片性能、扫描电镜的测试与表征对马来酸酐磺酸盐类阴离子表面活性剂结构、脱墨效果进行考察。结果表明:当马来酸酐磺酸盐类阴离子表面活性剂与AEO-9、AEO-3以2∶1∶1的比例进行复配时,中性脱墨效果比较理想,白度值提高14%ISO以上,尘埃度下降170mm2/m2以上。Neutral deinking agents were obtained by compounding maleate sulfonate ionic surfactants with two nonionic surfactants,fatty alcohol polyethenoxy ether AEO-9,AEO-3.The maleate sulfonate ionic surfactants were prepared by using maleic anhydride,polyoxyethylene alkyphenol （TX-10）,sodium sulfite.The structure of maleate sulfonate anionic surfactant and the deinking effect were investigated by FTIR,SEM.The results show that when the ratio of maleate sulfonate anionic surfactant：AEO-9：AEO-3 is at 2∶1∶1,the effect of neutral deinking is ideal,the whiteness of the deinking pulp can be increased above 14%ISO and the residual ink concentration can be decreased above 170mm2/m2.
