一种含硅磷酸酯加脂剂的制备及性能

Preparation and Performance of Polyether Siloxane Phosphobetaine Fatliquoring Agent

以聚醚醇胺硅油、环氧氯丙烷、磷酸二氢钠为原料，制备了聚醚改性硅氧烷磷酸酯甜菜碱，并进行结构表征。将其与亚硫酸化鱼油、磷酸化蓖麻油复配后进行粒径检测，并用于猪服装革加脂，结果表明：这种加脂剂乳液粒径分布范围为10－1000nm，平均粒径为230．7nm，具有良好助染性，用之加脂后的皮革柔软度、丰满性良好，并具有较好的物理机械性能。

The siloxane phosphobetaine （PPBPS） was prepared by polyether and alcohol amine modified polysiloxane, epichlorohydrin, sodium dihydrogen phosphate and characterized by IR and chemical analysis method. A novel fatliquoring agent was prepared by PPBPS mixed with sulfited fish oil and phosphated castor oil, and was used in pigskin wet blue leather. The results show that the fatliquoring agent emulsion particle diameter is 10 - 1000nm, average particle size is 230.7nm, and it has good level dyeing property, the leather has good flexibility, and fullness, the mechanical properties of leather is also good.
