| 摘 要： | 探讨了氧化铁颜料对木纤维．高密度聚乙烯复合材耐老化性能的改善作用。采用四种常用的氧化铁颜料与木纤维、高密度聚乙烯和其他加工助剂干混，并用自行设计的双螺杆／单螺杆双阶挤出机组制造木塑复合材料。对该木塑复合材料进行人工加速紫外循环老化处理，用CIE1976L^＊a^＊b^＊表色体系和ASTMD790标准分别对老化前后的材料进行测试，结果显示加入颜料以后木塑复合材料的抗弯弹性模量没有明显的变化，但是弯曲强度都有一定程度的提高。经过2000h人工加速紫外老化以后，不论是颜色要是力学性能都发生了明显的变化。铁红和铁黑着色的试样在整个老化过程中表现较好，颜料添加量约2．28％比较适宜。

| Abstract: | Four kinds of iron oxide pigments were added into wood-fiber/high-density-polyethylene composites (WF/HDPE) at three different concentrations, to determine the effects of pigments on the changes in the color and mechanical properties of the composites before and after UV accelerated weathering. HDPE, wood fibers, pigments and other processing additives were dry-mixed in a high-speed mixer. The mixtures were extruded by two-step extrusion process with a self-designed twin-screw/single-screw extruder system. ... |
