Research On The Synthesizing And Micro-emulsifying Of Amino-silicone Oil

In this thesis, the development history, classification oftextile softener of silicones and the common property of amino-silicone oil are briefly introduced. Moreover, synthetic methodsand the techniques of micro-emulsifying of amino-silicone oil areespecially explained and the factors affecting the polymerizationand micro-emulsification are discussed. The results show that:1.A series of amino-silicone oil with different-value and viscositywere prepared with octamethylcyclotetrasilane and N-beta-aminoethyl-gamma-aminopropylmethydimethoxysilane at potassiumhydroxide catalyst by bulk polymerization.2. The optimized synthesis conditions is the reaction time 4~~5h; the reaction temperature 135-145@ and the dosage of catalyst =0.06?.08% of the reactant mass.3. The compound emulsifier made through blending fatty alcohol polyoxyethylene ether and alkyphenol polyoxyethylene ether can emulsify and prepare ami no-si 1icone oi] into a transparent and clear micro-emulsions, with the diameter of its granule less than 0. 15um(150nm)4. The ratio of compound emulsifier is fatty alcohol polyoxyethylene ether taking up 60% and alkyphenol polyoxyethylene ether takingup 40%. The volume of usage is 43% of gravity of amino-silicone oil amino-silicone oil.5. The micro-emulsifying technique of amino-silicone oil is to stir the amino-si1icone oil in routine facilities together with the compound emulsifier with the speed of the agitator at 80 ~ 100r/min, no need of facilities with high speed and high shearing force and no need of raising temperature as well. On the condition of common temperature with 30 minutes stirring, the micro-emulsion of amino-si 1 icone fluid with good stability could be obtained.6. Adding a little of NZ and NS in mi croemulsion, the nature of its yellowing is considerably reduced with no concerns of increasing cost and decreasing softness .7. Micro-emulsion should have an excellent effect while applied to soft treatment of textile.
