摘要: The rice husk ash/natural rubber (RHA/NR) composites were prepared by latex blending process using the RHA modified with silane coupling agent. The structure and morphology of modified RHA were studied. The dispersing performance of modified RHA in the composites was evaluated from the structure and thermal properties. The results indicate that silane coupling agent KH-570 can react with the carboxyl of the RI-TA surface, leading to a significant decrease in carboxyl absorption intensity and the obvious improvement in the dispersion of RHA particles in rubber matrix. As the modified RHA having grafted onto NR molecular chains can increase the interface force between RHA and rubber matrix, the thermal stability of RHA/NR composites thus can be improved. The RHA/NR composite of highest thermal stability can be prepared with RHA load of 5% shows the best.
