木粉增强聚丙烯力学性能的改善方法

以废弃木粉为增强材料,制备了木粉增强聚丙烯复合材料,研究了改善废弃木粉增强聚丙烯复合材料力学性能的途径。结果表明,通过适当的处理方法对木粉进行表面处理、对基体树脂进行改性,可以有效地提高复合体系的界面粘接强度,能大幅度改善复合体系的力学性能;采用短切玻璃纤维及玻璃纤维毡与废弃木粉组合,可以获得力学性能很高、能作为结构材料使用的复合材料。

Methods to modify mechanical properties of polypropylene compo sites reinforced by wood flour

Polypropylene composites reinforced with waste wood flour were prepared and methods to modify their mechani-cal properties are studied. Results show that the proper surface treatment of wood flour and the modification of matrix resin can effectively increase the interfacial adhesion strength and significantly improve the mechanical properties of the system. Compos-ites with high mechanical properties that can be used as structure materials can be obtained by combining waste wood flour and chopped glass fiber or glass fiber mat.
