Preparation, structure and properties of silane modified silica/natural rubber nanocomposite. Part I - Forming mechanism of nanocomposite.

Abstract

Natural rubber/silica nanocomposite were prepared by mixing aqueous suspension of bis(3-triethoxysilylpropyl) tetrasunfit silane (TESPT) modified silica with Hevea Brasilienis latex using a pulverisette type mixer. Dispersion of the modified silica was characterized by laser scattering particle size distribution analyzer and SEM. The results showed that silica in suspension with statistical parameters: median 3.5 (µm); mean 3.8 (µm); variance 4 (µm²); standard deviation 2 (µm) is necessary to make nanocomposite with size distribution in range of 30 -100
