| Abstract: | A nano - scale SiO2 modified polyacrylate emulsion is formulated with ammonium persulphate as initiator, anionic sodium dedecyl benzene sulfonate and OP- 10 as the compound emulsifier, acrylate and nano SiO2. The influence of the synthesis process, temperature, variety of emulsifier, introducing model of emulsifier to the properties of the emulsion is discussed. The structure and performance of the emulsion are characterized. The results show that the comprehensive properties of the modified emulsion are improved largely. The quality of the product conforms to the requirements specified in GB/T 1738--1993. |
