%X 采用自制的聚腰果酚对胶粉（RP）进行脱硫反应制得接枝改性胶粉（MRP），将其与天然橡胶（NR）共混，并研究MRP/NR共混体系的结构与性能。结果表明：MRP/NR共混体系的物理性能优于RP/NR共混体系，耐老化性能优于NR和RP/NR共混体系；添加六次甲基四胺（HMTA）可以进一步提高MRP/NR共混体系的物理性能，尤其是当MRP用量为50份、HMTA用量为0.5份时，MRP/NR共混体系的物理性能与NR硫化胶相当。;The modified rubber powder（MRP）was prepared by the desulfurization reaction between poly cardanol and RP，and MRP was blended with the NR to obtain MRP/NR，whose structure and properties were investigated.The results showed that，the physical properties of MRP/NR was superior to those of WRP/NR，and the aging resistance of MRP/NR was better than that of WRP/NR and NR.With the addition of HMTA，the physical property of MRP/NR was further improved.The physical property of MWRP/NR was almost equivalent to that of the NR when the content of MWRP and HMTA was 50 and 0.5 phr respectively
