采用高密度聚乙烯(HDPE)为树脂基体在一定加工条件下制备了高密度聚乙烯/木粉发泡材料,研究了马来酸酐接枝聚乙烯(MAPE)作为相容剂对材料的力学性能、泡孔直径分布的影响,比较了发泡材料和未发泡材料的力学性能.结果表明,MAPE含量为5%时,材料具有较好的力学性能,泡孔的存在对于材料的力学性能有着较为明显的影响;发泡材料和未发泡材料力学性能及其变化有所不同,未发泡材料力学性能变化较为显著;MAPE的含量对泡孔直径的分布有一定的影响.
The polyethylene/wood foamed composite was made under certain conditions used high-density polyethylene (HDPE) as the plastic matrix. The influences of the MAH-g-PE on the mean diameter distribution of the foams and mechanical properties of the material were studied. The results show that the mechanical properties of the foamed and unfoamed materials are better with 5% MAH-g-PE. The foams can influence the mechanical properties obviously. It is different between the mechanical properties of foamed and unfoamed composite as well as their changes. The mechanical properties of the unfoamed material change more obviously. The distribution of the foams also changes with different amount of MAH-g-PE.
