| Abstract: | Taking NaSiO3 as raw material, the nano-SiO2 latex was synthesized by the latex coprecipitation method, using some materials as assistants. And then, the nano-SiO2 was mixed with the natural latex to prepare the nano - SiO2 composites. The effects of the reaction temperature on the yield of nano - SiO2 and the marinating time on the properties of composites were investigated . The particle size of nano -SiO2 and the tensile fracture morphologies of nano-SiO2/NR composites prepared under different marinating time were observed by TEM and SEM respectively. The results showed that the nano - SiO2/NR composites synthesized by the latex coprecipitation method exhibited excellent capabilities. |
| Keywords: | latex coprecipitation method nano - SiO2 NR composites |
