| Abstract: | A series of natural rubber(NR) composites with modified kaolin(MK) and precipitated silica(PS) were prepared by melt blending,and their microstructure,gas barrier properties and mechanical properties were characterized.The results show that flake-like kaolinite and spherical silica particles are evenly dispersed in the natural rubber matrix.When NR is filled by MK or PS separately,the gas barrier properties of NR composites are improved gradually with the increasing of MK content,and MK is superior to PS in the barrier and reinforcing capability.When NR is filled by MK and PS blends,their gas barrier properties,tensile strength and tensile modulus all surpass that of NR composites filled by MK or PS separately,and MK/PS hybrid filler further improves the gas barrier properties and mechanical properties of NR composites. |
