| Abstract: | In order to obtain the environment-friendly acrylic emulsion with stable properties,the nano-SiO2 is produced from the hydrolysis of terrathyl orthosilicate(TEOS)under the alkaline conditions and introduced into the envirnoment-friendly acrylic emulsion after surface modification.The nano-SiO2/polyacrylate composite emulsion is successfully prepared.The effects of synthetic technology on monomer conversion and stability of emulsion are investigated in detail.The results show that,under the optimized conditions:the polymerization temperature is 75℃;emulsifier dosage is 5 wt%;the initiator is 0.6%;monomer conversion and comprehensive stability of the composite emulsion are better. |
