Microcrystal bead high-efficiency water-permeable composite brick and preparation method thereof
The invention relates to the technical field of composite bricks, and discloses a microcrystal bead efficient water-permeable composite brick and a preparation method thereof.The preparation method comprises the steps that ceramic shale particles, ceramic fine powder, white cement, a reinforcing agent and water are added into a stirrer, stirring and discharging are conducted, and a base layer is obtained; adding the natural colored sand, the modified polyurethane, the epoxy nano silicon dioxide, the quartz powder and the polycarboxylate superplasticizer into a stirrer, stirring, and uniformly paving on the base layer for extrusion forming. In the stirring process, a terminal hydroxyl group in the modified polyurethane reacts with an epoxy group in the epoxy nano silicon dioxide to generate a ring-opening reaction, so that the compatibility of the modified polyurethane and the epoxy group is increased, and the modified polyurethane and the epoxy nano silicon dioxide are more uniformly dispersed in the composite brick; the adamantane structure in the modified polyurethane has better stability, the mechanical property of the composite brick is improved, the durability of the composite brick is improved by the ferrocene group, and the durability and pressure resistance of the composite brick can be improved by the polyurethane.
本发明涉及复合砖技术领域，且公开了微晶珠高效透水复合砖及其制备方法，本发明通过将陶瓷页岩颗粒、陶瓷细粉、白水泥、增强剂、水加入到搅拌器中，搅拌，出料，得到基层；将天然彩砂、改性聚氨酯、环氧纳米二氧化硅、石英粉、聚羧酸减水剂加入搅拌器中，搅拌，均匀平铺基层上挤压成型。在搅拌的过程中，改性聚氨酯中的端羟基会和环氧纳米二氧化硅中的环氧基团进行反应，发生开环反应，增加了彼此的相容性，使其在复合砖中分散更均匀；改性聚氨酯中的金刚烷结构具有较好的的稳定性，提高了复合砖的机械性能，其中的二茂铁基团提高复合砖的耐久性，聚氨酯本身也可以提高复合转的耐久性和抗压性。
