【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。
[Abstract]:Using bamboo pulp and bagasse pulp as raw materials, environmental protection wall decoration materials were prepared by fiber molding and hot pressing. The fiber morphology of bagasse and bamboo pulp and the effects of fiber content on the properties of wall decoration materials such as stiffness tensile index breaking resistance and water filtration were studied. The results showed that the average length of bagasse pulp and bamboo pulp were 0.78 mm and 1.22 mm, respectively, which were complementary to each other in fiber morphology. With the increase of the amount of bamboo pulp, the water filtration speed of the slurry in the forming process is accelerated, and the forming cycle is greatly shortened. The stiffness, tensile index and breaking resistance index of the wall decoration materials obtained are all gradually increasing at first and then decreasing slowly. When the content of bamboo pulp was 70% (mass fraction), the stiffness, tensile strength and breaking resistance index of bamboo pulp reached the maximum, which increased the wall decoration materials by 77.02% and 21.7775%, respectively, and improved the physical properties of the wall decoration materials. The surface microstructure was characterized by SEM.
