摘　　要：以竹浆和蔗渣浆为原料,采用纤维模塑热压成型制得环保墙体装饰材料。研究了蔗渣和竹浆的纤维形态,以及纤维不同添加量对墙体装饰材料挺度、抗张指数、耐破指数和滤水等性能的影响。实验表明,蔗渣浆和竹浆纤维的平均长度分别为0.78和1.22mm,两者在纤维形态方面具有很好的互补性。随着竹浆添加量的增加,浆料在成型过程中滤水速度加快,极大缩短了成形周期,并且制得的墙体装饰材料的挺度、抗张指数、耐破指数均呈先逐渐增大后缓慢减小的趋势。当竹浆的添加量为70%(质量分数)时,挺度、抗张强度、耐破指数均达到最大,分别比纯蔗渣浆制得的墙体装饰材料提高了77.02%、26.69%和21.77%,很好地改善了墙体装饰材料的物理性能。材料表面微观结构采用SEM进行表征。Environmental molding decorative building materials were prepared with bagasse and bamboo fibers via the hot forming process of fiber molding.The morphological characteristics of bagasse and bamboo fiber were analyzed.The effect of addition of the bamboo pulp on stiffness,tensile,burst and drainage were investigated.The results indicate that the average length of bagasse and bamboo fiber is 0.78 and 1.22mm.They have very well complementary to each other in fiber form.The drainage rate of pulp in the forming process was faster with the increase of the addition of the bamboo pulp,and the stiffness,tensile index and burst index increase at first and then tend to decrease.When the addition of bamboo pulp was 70%(by mass),the stiffness,tensile index,and burst index increased 77.02%,26.69% and 21.77%,which well improved the physical properties of molding decorative building material.The surface microstructure of the material was analyzed with SEM.
