The invention belongs to the technical field of building materials, and discloses a preparation method of a water-resistant anti-freezing shale ganged brick. The preparation method comprises the following steps: (1) adding plant straw into a sodium bicarbonate aqueous solution and a zinc oxide aqueous solution to obtain slurry, adding a graphene oxide aqueous solution and 1-butyl-3-methylimidazolium chloride ionic liquid, uniformly mixing, and adding a single-walled carbon nanotube to obtain a modified plant straw cellulose solution; (2) taking shale, crushing, soaking in the modified plant straw cellulose solution, adding tetraethoxysilane, mixing, and carrying out constant-temperature and constant-pressure closed reaction to obtain modified shale; (3) mixing the modified shale with fly ash, adding water and a fluxing agent, stirring and mixing, performing compression molding, and drying to obtain a pretreated green body; and (5) firing and molding the pretreated green body to obtainthe water-resistant anti-freezing shale ganged brick. The method is safe and simple, and the prepared shale ganged brick has good water resistance, frost resistance and mechanical properties.
本发明属于建筑材料技术领域，公开了一种耐水抗冻页岩清水砖的制备方法。所述制备方法包括：（1）在碳酸氢钠水溶液和氧化锌水溶液中加入植物秸秆，得浆料，加入氧化石墨烯水溶液和1‑丁基‑3‑甲基咪唑氯盐离子液体，混匀后加入单壁碳纳米管得改性植物秸秆纤维素溶液；（2）取页岩，粉碎，浸泡于改性植物秸秆纤维素溶液中，加入正硅酸乙酯混合，恒温恒压密闭反应得改性页岩；（3）将改性页岩与粉煤灰混合，加入水、助熔剂，搅拌混合后压制成型，干燥得预处理坯体；（5）将预处理坯体烧制成型得耐水抗冻页岩清水砖。该方法安全简单，制备的页岩清水砖耐水性、抗冻性及力学性能都较好。
