【摘要】 <正>木塑复合材料因其兼具高分子材料和原木材料的优点而在汽车内饰、建筑、园林等领域得到广泛应用^[1,2]。但木塑复合材料的基体树脂大多为聚烯烃、聚氯乙烯等,其与木粉的界面相容性差、基体树脂难以降解,二次回收利用难。因此,制备高性能、可降解的聚合物基木塑复合材料具有重要意义。聚乙烯醇（PVA）是一种综合性能优异,在一定条件下可生物降解的更多还原

【Abstract】 The PVA Wood-plastic composites with good properties has been prepared by the solid-phase mechanochemical method,the results showed that milling pan can promote the effect of pulverization,dispersion and mechanical activation,moreover improve the interfacial compatibility of the components to achieve good processability and mechanical performance.With the increasing milling cycle,the average particle size of wood powder has been effectively reduced from 47μm reduced to 25μm,moreover the tensile strength of the sample with 30%wood powder increased from 16 MPa to 24 MPa,and the elongation at break increased from 32%to 85%.更多还原
