摘　　要：为阐明高密度重组竹的表面涂饰性能,分析了不同密度重组竹的表面形貌、粗糙度、润湿性和漆膜附着力,考察了密度对漆膜附着力的影响。结果表明:重组竹的密度越高,其表面越光滑,粗糙度越小,Ra最低仅为1.71μm。同时,随着重组竹密度的增大,蒸馏水、甲酰胺和二碘甲烷三种极性不同的液体的接触角变大,表面自由能也随之降低。受表面粗糙度和润湿性的影响,低密度的重组竹与高密度的相比,具有更高的漆膜附着性能。然而,根据GB/T4893.4—2013对漆膜附着力的分级,所有重组竹对水性和油性木器底漆的表面漆膜附着力均为2级,表明密度对重组竹表面的漆膜附着力无显著影响。研究结果可为高密度重组竹的表面涂饰处理提供理论支持。To reveal the surface coating performance of high-density bamboo scrimbers,this study investigated the morphology,roughness,wettability and film adhesion of the scrimbers with different densities and preliminarily discussed the effect of density on the film adhesion.The results showed that the high-density scrimbers had a smoother surface and lower roughness.The minimum roughness was 1.71 μm in Ra.The contact angles of distilled water,formamide,and diiodomethane on the scrimbers increased with the increasing density.At the same time,surface free energy decreased as well.As a result,bamboo scrimbers with low density had better the property of film adhesion than the ones with high density.According to Chinses standard GB/T 4893.4-2013,the film adhesion of the water-based and oil-based wood priming paints for all bamboo scrimbers reached Level 2,indicating that density had no significant effect on the surface film adhesion of the scrimbers.The results will provide a theoretical reference for the coating treatment of high-density bamboo scrimbers.
