相容剂改性竹粉基木塑复合材料

WPCs-based Bamboo Powder Modified by the Compatilizer

比较了MA-g-LDPE和MA-g-EVA两种相容剂对木塑复合材料的性能影响效果。结果表明:当马来酸酐接枝物的加入量为10～15份时,木塑复合材料的综合性能最好。利用MA-g-LDPE改性时,复合材料的拉伸强度、弯曲强度和耐热性较好,而利用MA-g-EVA改性时,复合材料在冲击强度、流动性和耐水性方面则提高较多。

The properties of bamboo powder and polypropylene composite which was modified by two kinds of maleic anhydride-grafted polymers were compared. The result showed when the compatilizer content was added in the range of 10 to 15 phr,the comprehensive properties of WPCs were optimal. With regard to compatilizer modified WPCs,anhydride-grafted LDPE made the composite better in tensile strength, flexural property and heat-resistance property than those of anhydride-grafted EVA,which exhibited enhancing impact strength,flowability and water resistance property.
