Clay brick with high alkali corrosion resistance and preparation method thereof
The invention discloses a clay brick with high alkali corrosion resistance and a preparation method of the clay brick. The clay brick is prepared from the following raw materials in percentage by weight: 50 to 70 percent of clay clinker, 20 to 40 percent of bauxite clinker, 5 to 15 percent of white mud and 5 to 10 percent of phosphoric acid. The preparation method comprises the following steps: respectively weighing the clay clinker, the bauxite clinker and the white mud according to the weight percentage, performing dry mixing, adding part of phosphoric acid, and performing wet mixing to obtain a mud material; aging the pug, adding the residual phosphoric acid, carrying out wet mixing again, and carrying out compression molding by using a brick press to obtain a green brick; drying the green brick, firing in a kiln, taking out after firing, and immersing in a phosphoric acid pool to obtain a clay brick impregnated with phosphoric acid; and carrying out heat treatment on the clay brick impregnated with phosphoric acid to obtain the clay brick. According to the preparation method, vacuumizing is not needed when the green bricks are immersed in the phosphoric acid, the temperature of the clay bricks immersed in the phosphoric acid for heat treatment in a kiln does not need to be too high, the requirements for equipment and production conditions are low, and the alkali corrosion resistance of the clay bricks is improved.
本申请公开了一种高抗碱侵蚀性能粘土砖及其制备方法，粘土砖的原料包括以重量百分含量计的下列各组分：粘土熟料50％～70％，铝矾土熟料20％～40％，白泥5％～15％，磷酸5％～10％。其制备方法包括：按照重量百分含量分别称取粘土熟料、铝矾土熟料及白泥，干混后加入部分磷酸，湿混，得到泥料；将泥料困料后加入剩余的磷酸，再次湿混，并用压砖机压制成型得到砖坯；将砖坯干燥、进窑烧制，烧制后取出并浸没于磷酸池中得到浸渍磷酸的粘土砖；将浸渍磷酸的粘土砖热处理得到粘土砖。该制备方法将砖坯浸没于磷酸时无需抽真空，浸渍磷酸的粘土砖在窑内热处理的温度也无需太高，对设备及生产条件的要求低，提高了粘土砖的抗碱侵蚀性能。
