Polyether alcohol amine modified silicone oil was synthesized by the reaction of diethanolamine with epoxy modified silicone oil, and then reacted with sodium chloroacetate or sodium 2-hydroxy-3-chloropropyl phosphate to prepare carboxybetaine (PBPS) and phosphoric acid, respectively. Esters betaine-type (PPBPS) silicone amphoteric surfactant, and the surface activity of the two betaine silicone surfactants was studied. The critical micelle concentrations of PBPS and PPBPS were 0.3 g / L and 0.6 g, respectively. / L, the surface tensions at CMC are 25.93 mN / m and 26.13 mN / m, respectively, and the HLB values range from greater than 13 and between 10 and 13, and it has been found to have good emulsifying properties, foaming properties and Antistatic performance.
