The Synthesis Of Amino-modified Silicone Softener Microemulsion

This paper summarized the bulk polymerization of octamethyl ring-tetrasilane with the two kinds of silicone coupling agents which are N,N-aminoethyl-aminopropyl methyl dimethoxysilane and ring-hexa aminopropyl methyl dimethoxysilane. We researched the influence of different catalysts on the reaction , discussed the relation of viscosity and time. We found it is the amount of coupling agents that decided the amino-number. We have discovered the best synthetic condition andsynthesized two softeners which is named RBK-5> RBM-60In addtion, we researched another the bulk polymerization of octamethyl ring-tetrasilane with the different hydrolytes of silicone coupling agents which are N,N-aminoethyl-aminopropyl methyl dimethoxysilane and ring-hexa aminopropyl methyl dimethoxysilane. As same as the above, researched the influence of different catalysts on the reaction , discussed the relation of viscosity and time. We found it was the amount of coupling agents that decided the amino-number. We have discovered the best synthetic condition and synthesized twosofteners which is named RBK-11, RBM-12.With two different alkyl phenol polyoxyethylene (OP) ,we have prepared compoud emulsifier according to the proportion of OP-4:OP-10=3: 7o We have emulsified the four softeners which hadbeen synthesized with the emulsifier above. The particle diameter of micro-emulsion is tens of nano-meters to hundreds of nano-meters. Compared to Japan-imported emulsifier E-08,both emulsifiers have good emulsifying effect.We had finished cotton fabric and polyester/cotton blended fabric using micro-emulsion, and discovered that fabrics had excellent soft feeling .The tear strength of different fabrics was increased about 30 percents and whiteness of the fabric was 78 percents or so after finishing which was 3 percents higher compared non-finished fabric. The crease recovery angle of the finished fabric had been raised.
