MEE对高粘度氨基硅油微乳化性能的研究

摘要

以高粘度氨基硅油为原料,选用脂肪酸甲酯乙氧基化物MEE-8和MEE-5两种非离子表面活性剂为复合乳化剂,正戊醇为助乳化剂,成功地制备了粒径小于50 nm的氨基硅油微乳液(固含量20%).讨论了各种因素对氨基硅油微乳液形成的影响,优化的条件为:乳化剂[m(MEE-8):m(MEE-5)=4∶1]用量42%(对氨基硅油质量),正戊醇用量7%(对氨基硅油质量),pH值为5.5～6.0.此氯基硅油微乳液能较好地改善织物的柔软性,且在应用过程中性能保持稳定.%Amino-silicone microemulsion of the parlicle size below 50 nm (20％ of solid content) was pre pared using heavy viscosity amino -silicone oil as raw material, nonionic surfactants fatty acid methyl ester ethoxylates MEE-8 and MEE-5 as complex emulsifier, 1-pentanol as coemulsifier.Some factors on the formation of amino-silicone oil microemulsion were also discussed.The optimal conditions were as follows: 42％ (on the weight of amino-silicone) of complex emulsifier [m(MEE-8) :m(MEE-5)=4:1], 7％ of 1 -pentanol ( on the weight of amlno-silicone), pH value 5.5～6.0.This amino-silicone oil microemulsion could improve the softness of the fabric, and the performance of microemulsion remained stable in the application process .
