Granules, put the pellets into a sealed iron bucket, stale for 55 hours until the moisture content of the pellets is 7.7%;

[0030] B. Under the pressure condition of 200MPa, use a press to press the stale material in step A into a green body, and the green body is dried at a temperature of 230°C to obtain a brick, and the mois...

Embodiment 3

[0033] The preparation method of the full-body ceramic exterior wall brick in this embodiment is obtained by using the following raw materials: 32 tons of clay, 27 tons of kaolin, 27 tons of stone rice, and 22 tons of high-alumina white mud; wherein, the total aluminum content of the raw materials 18%, total iron content 3%;

[0034] Its preparation method comprises the following steps:

[0035] A. Add the raw materials calculated in the above ratio and 20% water of the total amount of raw materials into a ball mill to grind to a particle size of 50 μm to 55 μm, then remove iron from the slurry and sieve it, and spray dry it with a spray drying tower. Granules, put the pellets into a sealed iron bucket, stale for 60 hours until the moisture content of the pellets is 7.5%;

Abstract

The invention discloses a preparation method of a full-body ceramic external wall tile and relates to the technical field of building material production. The full-body ceramic external wall tile is prepared from the following raw materials in percentage by weight: 25-32 percent of clay, 20-27 percent of kaolin, 20-27 percent of chicken girt and 15-22 percent of high-alumina white mud, wherein the total aluminum content of the raw materials is 14.5-18 percent, and the total iron content is smaller than or equal to 3 percent. The preparation method comprises the following steps: A, milling the raw materials with water, removing iron from the raw materials, and sieving, drying and ageing the raw materials; B, pressing the aged material in the step A into a green body, and then carrying out drying formation to obtain a green tile; and C, spraying glaze water on the surface of the green tile, then putting the green tile in a roller kiln, and drying and firing the green tile to obtain the full-body ceramic external wall tile. Compared with the prior art, the preparation method can solve the problem that the full-body ceramic external wall tile prepared by the traditional production process is poor in the compression resistance and the frost resistance and high in water absorption.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a method for preparing full-body ceramic exterior wall bricks. Background technique [0002] Full-body ceramic exterior wall tiles are ceramic tiles with the same material and color on the front and back sides. The existing full-body ceramic exterior wall tiles are made of natural stone as raw materials, and are prepared through production processes such as batching, ball milling, spray drying, high-pressure pressing, and calcination. And the surface is directly polished without glazing, which has good anti-skid and wear resistance. This type of brick body is a common choice for exterior wall tiles; but the full-body ceramic exterior wall tiles prepared by the existing methods have the following problems. The raw material is natural stone, which has many impurities without screening. After polishing, the brick surface is rough and the pores are exposed, resul...
