Investigation of Silane Coupling Agents on the Filler-Filler and Filler-Rubber Interaction and Mechanical Properties of EVM/ATH Composites

摘要

Ethylene vinyl acetate copolymer (EVM)/aluminium trihydrate (ATH) composites were prepared. Vinyl-trimethoxysilane (VTMO), triethoxyvinylsilane (VTEO), ethyltrimethoxysilane (ETMO), amino-propyl-trimethoxysilane (AMMO) four kinds of silanes were used in this research. The effects of silane amount and different kinds of silane on the dispersion and adhesion of the ATH in EVM composites were characterized through RPA, electron microscopy, bound rubber. It was found that the addition of VTMO/AMMO/VTEO led to a dramatic increase in Payne effect and tensile property of the composites. Filler dispersion increased with silane adding, and the interaction of ATH and EVM was found in silane treated composites, in which silane had effective functional groups.
