小麦秸秆粉末/NR复合材料的性能研究

制备小麦秸秆粉末/NR复合材料，并对其性能进行研究。结果表明，小麦秸秆粉末对NR无明显补强作用，但具有良好的填充作用；采用氢氧化钠溶液、硅烷偶联剂KH-550或其水溶液对小麦秸秆粉末进行表面处理，均可改善复合材料的物理性能，其中硅烷偶联剂KH-550水溶液的效果较好。;A wheat-straw powder/NR composite was prepared，and its properties were investigated.The results showed that the wheat-straw powder had little reinforcing effect on NR，but had good filling effect；when the wheat-straw powder was modified by sodium hydroxide solution，silane coupling agent KH-550 or its solution，the physical properties of wheat-straw powder/NR composite were improved；the silane coupling agent KH-550 solution possessed better modifying effect
