摘　　要：以脂肪酸聚氧乙烯醚LAE-9、脂肪酸聚氧乙烯醚双酯DQA-600作为复合乳化剂,以矿物油为油相,制备了纺丝油剂微乳体系,并对其性能进行了系统的研究.研究表明：LAE-9与DQA-600比例为7∶3时,可显著降低矿物油与水相之间的界面张力,从而减小乳液的粒径;当复合乳化剂/矿物油比例在5∶5~9∶1的范围内时,可以形成一定浓度的微乳液,且当复合乳化剂/矿物油比例为7∶3时,形成微乳液的浓度范围最宽.乳液的电导率及运动粘度随着乳液中含水量的变化有显著地改变：在含水质量分数小于20.97%时,随着含水量的增加乳液电导率增加缓慢,之后讯速增大,含水质量分数超过64.12%后电导率又迅速下降;乳液运动粘度随浓度的增加先增大后减小,并在质量分数达到50%时乳液运动粘度达到最大值.矿物油含量增加使乳液粒径有所增大,而乳液质量分数在小于20%的范围内,浓度变化对乳液粒径及其分布影响并不大,但温度的升高却使乳液粒径增大且分布变宽.A series of spinning oil microemulsion was prepared by using luaric acid polyoxyethylene esters （LAE-9） and polyoxyethylene fatty acid diester DQA-600 as emulsifier and mineral oil as the oil phase. The performance of the microemulsion was systematically investigated. The results show that the best mass ratio of the hydrophilic to hydrophobic emulsifier is 7：3, at which the emulsifier can significantly reduce the interfacial tension between mineral oil and water phase, thereby reducing the particle size of the formed emulsion. And the microemulsion can be prepared in a certain range of concentration when the mass ratios of compound emulsifier and mineral oil are changing in the range from 5：5 to 9：1, among which at the ratio of 7：3 microemulsion could be prepared in the maximum concentration range. The conductivity and kinematic viscosity of the emulsion change significantly with the change of water content in the emulsion. The conductivity increases slowly with the increase of water content as the water content is less than 20.97%, and then it grows rapidly followed by a sharp decrease when moisture content exceeds 64.12%. And with the increase of the emulsion concentration, the kinematic viscosity of emulsion increases and reaches the maximum when its concentration reaches 50%. The increase of mineral oil content induces an increase of droplet size in emulsion, and the change of concentration has little influence on the size and distribution of emulsion droplet when emulsion concentration is less than 20%. However, with the temperature elevating, the size of emulsion droplet increases and its distribution becomes wider.
