| Abstract: | Comb-shaped amino silicone polyether was synthesized by epoxy polyether and amino silicon, which were synthesized by octamethylcyclotetrasiloxane with N,N-dimethyl-γ-aminopropyl-γ-aminopropyl methyl dimethoxysilane,N-β-aminoethyl-γ-aminopropyl methyl dimethoxylsilane and hexamethyldisiloxane.The structures of aminosiloxane and amino silicone polyether were characterized by IR and ~1H NMR.The composite defoamer was formulated with following composition (weight basis): 24% dimethyl silicone oil of different viscosity,4% amino silicone polyether,3% fumed silica, 4% emulsifier (Span-60,Tween-60,HLB value = 9),1% thickening stabilizers,and 64% deionized water. |
