摘　　要：以加速老化为手段,考察氙灯照射和冻融循环对高密度聚乙烯(HDPE)/稻糠粉和HDPE/秸秆粉两种木塑复合材料弯曲强度的影响。结果显示,同等条件下,HDPE/秸秆粉木塑复合材料的弯曲强度显著大于HDPE/稻糠粉木塑复合材料。经过氙灯照射和冻融循环后,两种木塑复合材料的弯曲强度均下降,且它们的弯曲强度下降程度随着氙灯照射时间的增加而增加,随着冻融温差的增加而增加。无重复双因素方差分析结果显示,氙灯老化时间和冻融循环温度对两种木塑复合材料的弯曲强度影响均非常显著(p<0.05,这里p表示显著性差异水平)。In this paper by taking accelerated weathering testing, we examined the effect of xenon lamp irradiation and freeze-thaw cycle on the bending strength of high density polyethylene （HDPE） /rice chaff powder wood-palstic composites and HDPE/stalk powder wood-palstic composites. The results show that the bending strength of HDPE/stalk powder wood-palstic composites was significantly greater than that of HDPE/ rice chaff powder wood-palstic composites under the same conditions. After the irradiation of xenon and freeze-thaw cycles, the bending strength of two kinds of composites was decreased. And the bending strength of two kinds of composites decreased along with the increase of xenon lamp irradiation time, and with the increase of freeze-thaw temperature difference. Results of two factor analysis of variance show that effects of xenon accelerated weathering time and freeze-thaw cycles temperature on the bending strength of two kinds of wood plastic composites were significant.
