摘　　要：利用聚氨酯的特性对有机硅进行改性,通过改变高键能和低表面能的Si-O键,使其具有良好的氧化稳定性和耐水性。文中提出聚氨酯改性有机硅高分子表面活性剂的制备与性能研究。准备制备原料和仪器后,将20.0%、25.0%、30.0%体积的端羟烃基聚硅氧烷3667分散在70.0%体积的聚乙二醇(PEG2000)中,同时加入去离子水进行定量,得到聚氨酯改性的有机硅表面活性剂。在性能测试阶段,分别对目标产物的红外光谱分布情况以及表面张力情况进行测试,对端羟烃基聚硅氧烷3667浓度与表面活性剂性能之间的关系进行了综合分析。Using the characteristics of polyurethane to modify organic silicon can enhance its oxidation stability and water resistance through high bond energy and low surface energy Si-O bonds.This paper proposes the preparation and performance research of polyurethane modified organic silicon polymer surfactants.After preparing specific preparation materials and instruments,20.0%,25.0%,and 30.0%volumes of terminated hydroxyalkyl polysiloxane 3667 were dispersed in 70.0%volume of polyethylene glycol(PEG2000),and deionized water was added for quantification to obtain polyurethane modified organosilicon surfactant.In the performance testing stage,the infrared spectrum distribution and surface tension of the target product were tested separately,and a comprehensive analysis was conducted on the relationship between the concentration of hydroxyl terminated polysiloxane 3667 and the performance of surfactants.
