The Preparation Of Modified Siloxane Surfactant And Its Application In Emulsifying Silicone Oil

Two novel better stability siloxane cationic surfactants were prepared used industrial raw materials in this paper. They were used to emulsify silicone oil with aliphatic non-ionic surfactants, the better application oil emulsion were obtained.One novel siloxane cationic surfactant was prepared used N-β-aminoethyl-y-aminopropyl methyl dimethoxy silane (KH-602) as coupling agent, octamethyl cyclotetrasiloxane (D4) as chain extender and 3-chloro-2-hydroxypropyl-trialkyl ammonium halide as modifier. The siloxane cationic surfactant with the best application effect was prepared through studying amino-silicone oil viscosity, the amino value, the reactant ratio and dimethyl amine on product impact, and the optimum amount of emulsifier was reduced in equal application effects and the best emulsifier ratio.Another novel siloxane cationic surfactant was prepared via hydrogen silicone oil (203 B) modified by AGE, F6, DMA and so on, adjusting reactant ratio on the basis of emulsifying silicone oil, especially in dimethy silicone oil, and then the better product was prepared. In addition, the better emulsifier and ratio were found in emulsifying dimethy silicone oil.
