摘要：以硅烷偶联剂、木质素纤维、双氧水作为改性剂，对建筑废弃物粉末进行改性，并将改性后形成的水性复配物作为胶凝材料替代部分水泥，与建筑废弃物颗粒充分混合，制成轻质隔墙板，研究了木质素纤维掺量和建筑废弃物颗粒掺量对轻质隔墙板力学性能的影响，并进行了SEM微观分析。结果表明：改性后的建筑废弃物水性复配物具有与水泥相同功效的凝胶性质，在交联聚合作用下，可形成稳定的三维网络结构，有效提高轻质隔墙板的力学强度；随着木质素纤维掺量和建筑废弃物颗粒掺量的增加，轻质隔墙板的力学性能均呈先增大后减小的趋势，最佳木质素纤维掺量为6%，适宜建筑废弃物颗粒掺量为42%左右。 Abstract: With silane coupling agent, lignin fiber and hydrogen peroxide as modifiers, the construction waste powder was modified, and the modified water-based compound was used as the cementitious material to replace part of cement, which was fully mixed with the construction waste particles to prepare lightweight partition board. The influence of lignin fiber content and construction waste particle content on the mechanical properties of lightweight partition board was studied, and the SEM microscopic analysis was carried out. The results show that the modified water-borne compound of construction waste has the same gel property as cement, and can form a stable three-dimensional network structure under the cross-linking polymerization, effectively improving the mechanical strength of lightweight partition board. With the increase of lignin fiber content and construction waste particle content, the mechanical properties of lightweight partition board are increased first and then decreased, and the optimum content of lignin fiber is 6%, and the suitable content of construction waste particle is about 42%.
