摘　　要：利用氯乙酸钠对聚醚醇胺改性硅油(PAPS)进行季铵化改性制备聚醚改性硅氧烷甜菜碱(PBPS),通过正交试验对合成条件进行优化,并将其应用于皮革加脂。试验结果表明:PBPS的最佳合成条件为:n(ClCH2COONa)∶n(叔胺)=1.1∶1,温度为80℃,反应时间为6h。PBPS与磷酸化蓖麻油、亚硫酸化鱼油复配后用于皮革加脂,成革柔软、丰满、滑爽性好,具有一定的助染性,是一种性能优良的加脂剂。The alcohol - amine modified polysiloxane （PAPS） reacted with sodium chloroacetate to form the polyether - modified betaine functional siloxane surfactant （PBPS）via quaternary ammonium reaction, the major influencing factors were studied by orthogonal design test, and PBPS applied to fatliqouring. The results show that the best synthesis process of orthogonal design test is that：n （sodium chloroacetate） ： n （intermediate） = 1.1 ： 1 ,reaction temperature is 80℃ and reaction time is 6h. PBPS is com- plexed with phosphated castor oil, sulfited fish oil and applied to fatliqouring, the leather is good at good softness, fullness, liveliness and dyeing ability. So PBPS could be use to make good fatliqoaring agent.
