Abstract: 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.
