【摘要】 采用低密度聚乙烯 (LDPE)与木粉制得了木粉 /LDPE复合材料。研究了木粉用量、表面处理剂种类及用量以及发泡剂用量对复合材料性能的影响 ;并对化学发泡法减轻复合材料自重的方案做了初步探讨。结果表明 :当木粉用量为 3 0份 ,表面处理剂用量为木粉质量的 1 0 %时 ,复合材料的综合性能最佳 ;添加 4份AC发泡剂后 ,复合材料的密度从 0 83g/cm3 降到 0 5 2g/cm3 ,化学发泡法可有效减轻材料的自重更多还原

【Abstract】 Wood flour/LDPE composite (WPC) was prepared from LDPE and wood flour, the effects of the content of the wood flour, the effects of the type and content of surface treatment agent, and the effect of the content of foaming agent on the properties of WPC were studied, and the reducing of the specific weight of the composite by the use of foaming agent was studied tentatively. The results showed that the overall property of the composite was the optimum when the content of the wood flour was 30 phr,and the content of the surface treatment agent C was 10% of the mass weight of the wood flour. When the content of foaming agent AC was 4 phr, the specific density of the composite decreased from 0.83 g/cm 3 to 0.52 g/cm 3. The use of chemical foaming agent could decrease the specific weight of the composite effectively.更多还原
