摘　　要：研究了球磨胡桑木粉苄基化改性后的增重率与材料热塑性以及力学性能的关系。随着增重率的增加,即胡桑木粉苄基化反应程度的提高,产物的热塑性变好,但材料的拉伸强度和弯曲强度增加到一定程度后,反而随着增重率的增加而下降。以胡桑木粉苄基化产物为基体,分别以球磨胡桑木粉、蒙脱土为增强材料进行共混制备复合材料,探讨增强材料与木粉苄基化产物基体的质量比对复合材料力学性能的影响。试验结果表明,复合材料的力学性能优于胡桑木粉苄基化产物,其拉伸强度和弯曲强度随增强材料质量分数的增加而先增加后降低。The relationships between weight gain rate and the thermoplasticity along with mechanical properties of ballmilled benzylated mulberry flour were investigated.The thermoplasticity of benzylated mulberry flour improved with the increasing of weight gain rate,but the tensile strength and flexural strength were increased initially and then decreased with the increasing of weight gain rate.Mulberry flour and montmorillonite reinforced benzylated mulberry flour composites were prepared.The influence about quality ratio of reinforced materials and benzylated mulberry flour on benzylated mulberry flour composites was studied.The results showed that the mechanical properties of benzylated mulberry flour composites were superior to benzylated mulberry flour.The tensile strength and flexural strength were increased initially and then decreased with the increasing of reinforced materials content.
