Preparation method of ceramic color sand matrix
The invention discloses a preparation method of a ceramic colored sand matrix. The preparation method comprises the following steps: (1) weighing the following raw materials in percentage by weight: 40-50% of red mud, 10-25% of fly ash, 3-10% of shale, 5-12% of coal gangue, 1-5% of bentonite, 2-8% of talc and 4-10% of quartz; (2) respectively carrying out ball milling and sieving on the raw materials; (3) uniformly mixing the materials, adding a proper amount of water, kneading into pug, manually kneading into balls, and naturally drying; and (4) sintering the dried ball blank in a silicon carbide rod furnace. The water absorption rate of the colored sand matrix prepared by the process is about 20%, the porosity is 30-40%, the volume density is 1.8-2.2 g/cm<3>, the crushing strength is about 30 MPa, the acid resistance and alkali resistance are respectively greater than 95% and 99%, and the use requirements can be satisfied.
本发明公开了一种陶瓷彩砂基体的制备方法，包括如下步骤：(1)按以下重量配比称取原料：赤泥40～50％，粉煤灰10～25％，页岩3～10％，煤矸石5～12％，膨润土1～5％，滑石2～8％，石英4～10％；(2)上述原料分别球磨、过筛；(3)将上述混合均匀后，加适量的水揉练成泥料，然后手工搓制成球，自然干燥；(4)将干燥后的球坯置于硅碳棒炉中烧成。本发明公开的工艺方法制备得到的彩砂基体吸水率在20％左右，气孔率在30～40％之间，体积密度在1.8～2.2g/cm3之间，压碎强度为30MPa左右，耐酸耐碱性分别大于95％和99％，能满足使用要求。
