新型轻质玻化微珠墙体保温板的性能研究

玻化微珠是一种具有质轻、保温、隔热、防火和耐久性好等诸多优点的新型无机轻质骨料、以玻化微珠为轻质骨料，108胶和水泥为胶粘剂，掺加适量的粉煤灰、纤维及防水剂，经模压成型制备玻化微珠墙体保温板。通过正交试验进行试验配比优化，同时研究成型压力、水泥掺量、粉煤灰取代量和纤维掺量对玻化微珠保温板性能的影响；通过SEM扫描电镜对玻化微珠保温板进行内部微观形貌观察，研究界面结合情况以及断面微观形貌，并探讨相关作用机理，试验最终得出玻化微珠保温板最佳工艺参数为：成型压力0．78MPa、水泥掺量60％、粉煤灰取代量20％、纤维掺量1．0％。

Study on the performance of new lightweight glazed hollow beads wall thermal insulation board

Glazed hollow beads is a new inorganic lightweight aggregate which has many advantages such as light weight, thermal insulation, fireproof and good durability. Glazed hollow beads as lightweight aggregate, 108 plastic and cement as adhesive, and fly ash, fibers and waterproofing agent as additives, a kind of glazed hollow beads thermal insulation board is moulded. The optimal parameters of the glazed hollow beads thermal board are determined by orthogonal test.
