摘　　要：化学纤维由于本身吸湿性差,在纺丝过程中容易产生静电,需要添加纺丝油剂,抗静电剂作为纺丝油剂的重要组成成分,对于纺丝工艺和后道加工具有重要意义。以AEO-3为原料、P_(2)O_(5)为磷酸化试剂,经过酯化、水解和中和等步骤制备了AEO-3磷酸酯钾盐型抗静电剂,主要探究了对合成工艺影响最大的投料比、酯化时间和水解时间对产物中单酯、双酯、游离磷酸、电导率和表面张力等的影响规律,实验结果表明:当AEO-3和P_(2)O_(5)的投料比为3:1、酯化时间为4 h,水解时间为4 h时,所制备的AEO-3磷酸酯钾盐型抗静电剂的效果最好,此时单酯含量高达62.4%,双酯含量为31.5%,1%含固量水溶液的电导率高达1702 us/cm,表面张力为30.6 mN/m,具有良好的抗静电效果。另外,该抗静电剂与化纤油剂主要成分矿物油(10#和15#白油)、月桂醇油酸脂等的相溶性好,具有实际应用价值。Due to the poor hygroscopicity of chemical fibers,it is easy to produce static electricity during the spinning process and necessary to add spinning oil.As an important component of spinning oil,antistatic agent is of great significance for spinning process and post-processing.In this paper,AEO-3 was taken as raw material and P_(2)O_(5) as phosphorylation reagent,AEO-3 phosphate potassium antistaticagent was prepared by esterification,hydrolysis and neutralization steps.The influence law of feed ratio,esterification time and hydrolysis time on the monoester,diester,free phosphoric acid,conductivity and surface tension of the product was investigated.The experimental results showed that when the feed ratio of AEO-3 to P_(2)O_(5) was 3:1,the esterification time was 4 h and the hydrolysis time was 4 h,the prepared AEO-3 phosphate potassium antistatic agent had the best effect,and the monoester content was as high as 62.4%,the content of diester was 31.5%,the conductivity of 1%solid content aqueous solution was as high as 1702 us/cm,and the surface tension was 30.6 mN/m,which had good antistatic effect.In addition,the antistatic agent had good compatibility with the main components of chemical fiber oil such as mineral oil(10#and 15#white oil)and lauryl alcohol oleic acid ester,which had practical application value.
