Preparation method of high-strength hollow brick
The invention discloses a preparation method of a high-strength hollow brick. The preparation method comprises the following steps: A, mixing shale, coal gangue and a first pore-forming agent with water, and aging to obtain a prefabricated material; B, in a stirring state, adding a second pore-forming agent into the prefabricated material, and mixing to obtain a primary material; C, performing extrusion molding on the primary material to obtain a green brick; D, sequentially carrying out three-stage drying treatment on the obtained green brick to obtain a pre-sintered brick; and E, sintering the pre-sintered brick, The first pore-forming agent is granular and/or powdery, and the second pore-forming agent is slurry; and the temperature of the drying treatment in at least one stage is not higher than the boiling point of water. The effects that the requirements for materials are not high, and the strength of the hollow brick can be improved in a targeted mode are achieved.
本发明公开了一种高强度空心砖的制备方法，所述制备方法包括：A、将页岩、煤矸石和第一成孔剂加水混合后陈化，得到预制料；B、在搅拌状态下，向所述预制料中加入第二成孔剂进行混合，得到初制料；C、将初制料挤出成型，得到砖坯；D、将得到的砖坯顺次进行三个阶段的干燥处理，得到预烧结砖；E、对预烧结砖进行烧结；其中，所述第一成孔剂为颗粒状和/或粉末状，所述第二成孔剂为浆料；至少其中一个阶段的干燥处理的温度不大于水的沸点。实现了对于材料本身要求不高，其能够针对性提高空心砖强度的效果。
