摘 要：Nano SiO2/NR composites were prepared through blending nano SiO2 emulsion with natural rubber latex and then concreting with acetic acid. The emulsion nano SiO2 was prepared with Na2SiO3·9H2O and hydrochloric acid under the reaction of the assistant agents. The was analyzed effect of the application rates of assistant agents such as silane coupling agent, surfactant, nucleating agent and dispersant on the properties and interface structure of the nano SiO2/NR composites with IR, TEM, SEM, DMA was analyzed. An orthogonal test was arranged to select optimum condition. The results show that the best combination for preparing nano SiO2/NR composites is as follows: the rate of the silane coupling agent (TESPT), the surfactant(dodecyl benzene sulfonate natrium), nucleating agent(AlCl3) and dispersant(ethylene diamine tetraacetie acid) in the course of preparing nano SiO2 are 15%, 2.0%, 2.5% and 0.4%, respectively. Several replications in the experiment had produced desirable nano SiO2 products and nano SiO2/NR composites with better properties.
