目的 研究瓦楞纸板在沾染油脂后其力学性能受到的影响。方法 采用涂布的方式将油脂均匀涂覆在瓦楞纸板表面， 通过改变涂布量及样品放置时间来研究油脂沾染量及沾染时间对瓦楞纸板粘合强度、 边压强度及耐破强度的影响。结果 瓦楞纸板粘合强度、 边压强度及耐破强度均随着油脂沾染量的增加呈现不同程度的下降， 随着油脂沾染时间的增加先下降后趋于稳定。结论 油脂的沾染对瓦楞纸板粘合强度的影响较大， 对边压强度及耐破强度的影响较小。

The aim of this study was to investigate the influence of staining of grease on the mechanical properties of corrugated paperboard. Corrugated paperboard was coated with grease. By changing the coating weight and placing time of samples, the influences of stain amount and staining time on the ply adhesive strength, edgewise crush resistance and bursting strength of corrugated paperboard were studied. The ply adhesive strength, edgewise crush resistance and bursting strength gradually decreased with the increase of stain amount, while decreased and then became stable with the increase of staining time. The influence of staining of grease on ply adhesive strength was bigger than those of edgewise crush resistance and bursting strength.
